UICollectionView中的单元格间距

我如何在UICollectionView的一个部分设置单元格间距?我知道有一个属性minimumInteritemSpacing，我已经将它设置为5.0，但间距仍然没有出现5.0。我已经实现了flowout委托方法。

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section
{

    return 5.0;
}

我仍然没有得到想要的结果。我认为这是最小间距。有没有什么方法可以设置最大间距?

试试这个方法:

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView
                    layout:(UICollectionViewLayout*)collectionViewLayout
    insetForSectionAtIndex:(NSInteger)section {

    UIEdgeInsets insets = UIEdgeInsetsMake(?, ?, ?, ?);

    return insets;
}

请注意属性名minimumInterItemSpacing。这将是项目之间的最小间距，而不是精确的间距。如果你设置minimumInterItemSpacing为某个值，你可以确保spacing不会小于该值。但有机会获得更高的价值。

实际上，项目之间的间距取决于几个因素itemSize和sectionInset。集合视图根据这些值动态放置内容。所以你不能保证精确的间距。你应该用sectionInset和minimumInterItemSpacing做一些试错。

在头文件中定义UICollectionViewDelegateFlowLayout协议。

实现UICollectionViewDelegateFlowLayout协议的如下方法:

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
    return UIEdgeInsetsMake(5, 5, 5, 5);
}

点击这里查看苹果文档的UIEdgeInsetMake方法。

支持第一个问题。我试图在UICollectionView上获得5px的间距，但这并不奏效，以及UIEdgeInsetsMake(0,0,0,0)…

在UITableView中，我可以通过直接指定一行中的x,y坐标来做到这一点。

这是我的UICollectionView代码:

#pragma mark collection view cell layout / size
- (CGSize)collectionView:(UICollectionView*)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    return [self getCellSize:indexPath];  // will be w120xh100 or w190x100
    // if the width is higher, only one image will be shown in a line
}

#pragma mark collection view cell paddings
- (UIEdgeInsets)collectionView:(UICollectionView*)collectionView layout:(UICollectionViewLayout *)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
    return UIEdgeInsetsMake(0, 0, 0, 0); // top, left, bottom, right
}

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section {

    return 5.0;
}

更新:用下面的代码解决了我的问题。

ViewController。m

#import "ViewController.h"
#import "MagazineCell.h" // created just the default class. 

static NSString * const cellID = @"cellID";

@interface ViewController ()

@end

@implementation ViewController

#pragma mark - Collection view
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return 1;
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return 30;
}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    MagazineCell *mCell = (MagazineCell *)[collectionView dequeueReusableCellWithReuseIdentifier:cellID forIndexPath:indexPath];

    mCell.backgroundColor = [UIColor lightGrayColor];

    return mCell;
}

#pragma mark Collection view layout things
// Layout: Set cell size
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {

    NSLog(@"SETTING SIZE FOR ITEM AT INDEX %d", indexPath.row);
    CGSize mElementSize = CGSizeMake(104, 104);
    return mElementSize;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section {
    return 2.0;
}

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section {
    return 2.0;
}

// Layout: Set Edges
- (UIEdgeInsets)collectionView:
(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
   // return UIEdgeInsetsMake(0,8,0,8);  // top, left, bottom, right
    return UIEdgeInsetsMake(0,0,0,0);  // top, left, bottom, right
}

@end

我知道这个话题很老了，但如果有人还需要正确答案，你需要什么:

Override standard flow layout. Add implementation like that: - (NSArray *) layoutAttributesForElementsInRect:(CGRect)rect { NSArray *answer = [super layoutAttributesForElementsInRect:rect]; for(int i = 1; i < [answer count]; ++i) { UICollectionViewLayoutAttributes *currentLayoutAttributes = answer[i]; UICollectionViewLayoutAttributes *prevLayoutAttributes = answer[i - 1]; NSInteger maximumSpacing = 4; NSInteger origin = CGRectGetMaxX(prevLayoutAttributes.frame); if(origin + maximumSpacing + currentLayoutAttributes.frame.size.width < self.collectionViewContentSize.width) { CGRect frame = currentLayoutAttributes.frame; frame.origin.x = origin + maximumSpacing; currentLayoutAttributes.frame = frame; } } return answer; }

其中maximumSpacing可以设置为您喜欢的任何值。这个技巧保证了单元格之间的空间将等于maximumSpacing!!

2013-10-17 14:16:01

我使用monotouch，所以名称和代码会有点不同，但你可以通过确保集合视图的宽度等于(x *单元格宽度)+ (x-1) * MinimumSpacing与x =每行单元格的数量来做到这一点。

只需要根据MinimumInteritemSpacing和Cell的宽度执行以下步骤

1)我们根据单元格大小+当前插入+最小间距计算每行项目的数量

float currentTotalWidth = CollectionView.Frame.Width - Layout.SectionInset.Left - Layout.SectionInset.Right (Layout = flowlayout)
int amountOfCellsPerRow = (currentTotalWidth + MinimumSpacing) / (cell width + MinimumSpacing)

2)现在你有了所有信息来计算集合视图的预期宽度

float totalWidth =(amountOfCellsPerRow * cell width) + (amountOfCellsPerRow-1) * MinimumSpacing

3)所以当前宽度与预期宽度之差为

float difference = currentTotalWidth - totalWidth;

4)现在调整insets(在本例中，我们将其添加到右侧，因此集合视图的左侧位置保持不变

Layout.SectionInset.Right = Layout.SectionInset.Right + difference;

使用水平流布局，我也得到了10点之间的单元格间距。为了移除间距，我需要将minimumlinespespaces和minimumInterItemSpacing设置为零。

UICollectionViewFlowLayout *flow = [[UICollectionViewFlowLayout alloc] init];
flow.itemSize = CGSizeMake(cellWidth, cellHeight);
flow.scrollDirection = UICollectionViewScrollDirectionHorizontal;
flow.minimumInteritemSpacing = 0;
flow.minimumLineSpacing = 0;

此外，如果所有单元格大小相同，直接在流布局上设置属性比使用委托方法更简单、更有效。

2014-05-08 12:40:04

试试下面的代码，确保每个项目之间的间距为5px:

- (UIEdgeInsets)collectionView:(UICollectionView *) collectionView 
                        layout:(UICollectionViewLayout *) collectionViewLayout 
        insetForSectionAtIndex:(NSInteger) section {

    return UIEdgeInsetsMake(0, 0, 0, 5); // top, left, bottom, right
}

- (CGFloat)collectionView:(UICollectionView *) collectionView
                   layout:(UICollectionViewLayout *) collectionViewLayout
  minimumInteritemSpacingForSectionAtIndex:(NSInteger) section {    
    return 5.0;
}
2014-10-21 19:06:18

我偶然发现了与op类似的问题。不幸的是，接受的答案不适合我，因为collectionView的内容不会正确居中。因此，我提出了一个不同的解决方案，只需要在collectionView中的所有项目都具有相同的宽度，这似乎是问题中的情况:

#define cellSize 90

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
    float width = collectionView.frame.size.width;
    float spacing = [self collectionView:collectionView layout:collectionViewLayout minimumInteritemSpacingForSectionAtIndex:section];
    int numberOfCells = (width + spacing) / (cellSize + spacing);
    int inset = (width + spacing - numberOfCells * (cellSize + spacing) ) / 2;

    return UIEdgeInsetsMake(0, inset, 0, inset);
}

该代码将确保…minimumInteritemSpacing…将是每个collectionViewCell之间的精确间距，并进一步保证所有的单元格一起将在collectionView

2015-05-01 18:14:38

最流行的答案的Swift版本。单元格之间的空格将等于cellSpacing。

class CustomViewFlowLayout : UICollectionViewFlowLayout {

    let cellSpacing:CGFloat = 4

    override func layoutAttributesForElementsInRect(rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
        if let attributes = super.layoutAttributesForElementsInRect(rect) {
        for (index, attribute) in attributes.enumerate() {
                if index == 0 { continue }
                let prevLayoutAttributes = attributes[index - 1]
                let origin = CGRectGetMaxX(prevLayoutAttributes.frame)
                if(origin + cellSpacing + attribute.frame.size.width < self.collectionViewContentSize().width) {
                    attribute.frame.origin.x = origin + cellSpacing
                }
            }
            return attributes
        }
        return nil
    }
}

投票的答案(以及快速版本)有一个小问题:右边会有一个很大的空格。

这是因为流布局是定制的，以使单元格间距精确，具有浮动左行为。

我的解决方案是操纵部分插入，使部分是对齐中心，但间距是完全指定的。

在下面的截图中，项目/行间距正好是8pt，而左右插入部分将大于8pt(使其居中对齐):

这样的Swift代码:

private let minItemSpacing: CGFloat = 8
private let itemWidth: CGFloat      = 100
private let headerHeight: CGFloat   = 32

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    // Create our custom flow layout that evenly space out the items, and have them in the center
    let layout = UICollectionViewFlowLayout()
    layout.itemSize = CGSize(width: itemWidth, height: itemWidth)
    layout.minimumInteritemSpacing = minItemSpacing
    layout.minimumLineSpacing = minItemSpacing
    layout.headerReferenceSize = CGSize(width: 0, height: headerHeight)

    // Find n, where n is the number of item that can fit into the collection view
    var n: CGFloat = 1
    let containerWidth = collectionView.bounds.width
    while true {
        let nextN = n + 1
        let totalWidth = (nextN*itemWidth) + (nextN-1)*minItemSpacing
        if totalWidth > containerWidth {
            break
        } else {
            n = nextN
        }
    }

    // Calculate the section inset for left and right. 
    // Setting this section inset will manipulate the items such that they will all be aligned horizontally center.
    let inset = max(minItemSpacing, floor( (containerWidth - (n*itemWidth) - (n-1)*minItemSpacing) / 2 ) )
    layout.sectionInset = UIEdgeInsets(top: minItemSpacing, left: inset, bottom: minItemSpacing, right: inset)

    collectionView.collectionViewLayout = layout
}
2015-12-01 04:40:59

记住，它是最小行间距，而不是最小项间距或单元格间距。因为你的collectionView的滚动方向是水平的。

如果是垂直的，则需要为单元格之间的水平空间设置单元格空间或项间空间，为单元格之间的垂直空间设置行间距。

objective - c版本

- (CGFloat)collectionView:(UICollectionView *)collectionView
                       layout:(UICollectionViewLayout*)collectionViewLayout
    minimumLineSpacingForSectionAtIndex:(NSInteger)section
    {
        return 20;
    }

斯威夫特版本:

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return 20
}
2015-12-12 15:36:49

我有一个水平的UICollectionView和子类化的UICollectionViewFlowLayout。集合视图具有较大的单元格，并且每次只显示一行单元格，并且集合视图适合屏幕的宽度。

我尝试了iago849的答案，它起作用了，但后来我发现我甚至不需要他的答案。出于某种原因，设置minimumInterItemSpacing没有任何作用。我的项目/单元格之间的间距可以完全由minimumlinespace控制。

不知道为什么会这样，但确实有效。

上面vojtech-vrbka的解决方案是正确的，但它会触发一个警告:

警告:UICollectionViewFlowLayout缓存的帧不匹配索引路径-缓存值:这可能是因为流布局子类layout是修改UICollectionViewFlowLayout返回的属性而没有复制它们

下面的代码应该修复它:

class CustomViewFlowLayout : UICollectionViewFlowLayout {

   let cellSpacing:CGFloat = 4

   override func layoutAttributesForElementsInRect(rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
       let original = super.layoutAttributesForElementsInRect(rect)

       if let original = original {
           let attributes = NSArray.init(array: original, copyItems: true) as! [UICollectionViewLayoutAttributes]

           for (index, attribute) in attributes.enumerate() {
                if index == 0 { continue }
                let prevLayoutAttributes = attributes[index - 1]
                let origin = CGRectGetMaxX(prevLayoutAttributes.frame)
                if(origin + cellSpacing + attribute.frame.size.width < self.collectionViewContentSize().width) {
                    attribute.frame.origin.x = origin + cellSpacing
                }
            }
            return attributes
       }
       return nil
   }
}

我发现了使用IB配置单元格或行之间的间距的非常简单的方法。

只需从storyboard/Xib文件中选择UICollectionView，然后按下图所示单击大小检查器。

要以编程方式配置空间，请使用以下属性。

1)用于设置行间距。

[self.collectionView setMinimumLineSpacing:5];

2)用于设置项目/单元格之间的间距。

[self.collectionView setMinimumInteritemSpacing:5];

回答Swift 3.0, Xcode 8

1.确保你设置了集合视图委托

class DashboardViewController: UIViewController {
    @IBOutlet weak var dashboardCollectionView: UICollectionView!

    override func viewDidLoad() {
        super.viewDidLoad()
        dashboardCollectionView.delegate = self
    }
}

2.实现uicollectionviewdelegatflowlayout协议，而不是UICollectionViewDelegate。

extension DashboardViewController: UICollectionViewDelegateFlowLayout {
    fileprivate var sectionInsets: UIEdgeInsets {
        return .zero
    }

    fileprivate var itemsPerRow: CGFloat {
        return 2
    }

    fileprivate var interitemSpace: CGFloat {
        return 5.0
    }

    func collectionView(_ collectionView: UICollectionView,
                        layout collectionViewLayout: UICollectionViewLayout,
                        sizeForItemAt indexPath: IndexPath) -> CGSize {
        let sectionPadding = sectionInsets.left * (itemsPerRow + 1)
        let interitemPadding = max(0.0, itemsPerRow - 1) * interitemSpace
        let availableWidth = collectionView.bounds.width - sectionPadding - interitemPadding
        let widthPerItem = availableWidth / itemsPerRow

        return CGSize(width: widthPerItem, height: widthPerItem)
    }

    func collectionView(_ collectionView: UICollectionView,
                        layout collectionViewLayout: UICollectionViewLayout,
                        insetForSectionAt section: Int) -> UIEdgeInsets {
        return sectionInsets
    }

    func collectionView(_ collectionView: UICollectionView,
                        layout collectionViewLayout: UICollectionViewLayout,
                        minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 0.0
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
        return interitemSpace
    }
}

以前的版本并没有真正工作的部分> 1。所以我的解决方案在这里找到了https://codentrick.com/create-a-tag-flow-layout-with-uicollectionview/。对于懒惰的人:

override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
    let attributesForElementsInRect = super.layoutAttributesForElements(in: rect)
    var newAttributesForElementsInRect = [UICollectionViewLayoutAttributes]()
    // use a value to keep track of left margin
    var leftMargin: CGFloat = 0.0;
    for attributes in attributesForElementsInRect! {
        let refAttributes = attributes 
        // assign value if next row
        if (refAttributes.frame.origin.x == self.sectionInset.left) {
            leftMargin = self.sectionInset.left
        } else {
            // set x position of attributes to current margin
            var newLeftAlignedFrame = refAttributes.frame
            newLeftAlignedFrame.origin.x = leftMargin
            refAttributes.frame = newLeftAlignedFrame
        }
        // calculate new value for current margin
        leftMargin += refAttributes.frame.size.width + 10
        newAttributesForElementsInRect.append(refAttributes)
    }

    return newAttributesForElementsInRect
}

.m

@implementation MaxSpacingCollectionViewFlowLayout

    if (attributes.count <= 0) return attributes;

    CGFloat firstCellOriginX = ((UICollectionViewLayoutAttributes *)attributes[0]).frame.origin.x;

    for(int i = 1; i < attributes.count; i++) {
        UICollectionViewLayoutAttributes *currentLayoutAttributes = attributes[i];
        if (currentLayoutAttributes.frame.origin.x == firstCellOriginX) { // The first cell of a new row
            continue;
        }

        UICollectionViewLayoutAttributes *prevLayoutAttributes = attributes[i - 1];

            let previousAttributes = answer[i - 1]

            let maximumSpacing: CGFloat = 8
            let origin = previousAttributes.frame.maxX

            if (origin + maximumSpacing + currentAttributes.frame.size.width < self.collectionViewContentSize.width && currentAttributes.frame.origin.x > previousAttributes.frame.origin.x) {
                var frame = currentAttributes.frame
                frame.origin.x = origin + maximumSpacing

故事板的方法

在你的故事板中选择CollectionView，然后进入尺寸检查器，设置单元格和行的最小间距为5

Swift 5编程方式

lazy var collectionView: UICollectionView = {
        let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .horizontal

        //Provide Width and Height According to your need
        let width = UIScreen.main.bounds.width / 4
        let height = UIScreen.main.bounds.height / 10
        layout.itemSize = CGSize(width: width, height: height)

        //For Adjusting the cells spacing
        layout.minimumInteritemSpacing = 5
        layout.minimumLineSpacing = 5

        return UICollectionView(frame: self.view.frame, collectionViewLayout: layout)
    }()
2019-04-25 10:41:04

如果你在创建一个水平集合视图，那么为了在单元格之间留出空间，你需要设置属性minimumlinespcing。
