我在定制一个UITableView。我想隐藏在最后一个单元格上的分离线…我能这样做吗?
我知道我可以用tableView。separatorStyle = UITableViewCellStyle。没有,但是这会影响tableView的所有单元格。我希望它只影响最后一个单元格。

当前回答
在viewDidLoad中添加这一行:
self.tableView.separatorColor = [UIColor clearColor];
在cellForRowAtIndexPath中:
适用于iOS低版本
if(indexPath.row != self.newCarArray.count-1){
UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 2)];
line.backgroundColor = [UIColor redColor];
[cell addSubview:line];
}
适用于iOS 7以上版本(包括iOS 8)
if (indexPath.row == self.newCarArray.count-1) {
cell.separatorInset = UIEdgeInsetsMake(0.f, cell.bounds.size.width, 0.f, 0.f);
}
其他回答
在willdisplaycell:
cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)
在ios7中,UITableView分组样式单元格分隔符看起来有点不同。它看起来有点像这样:
我尝试了凯梅纳兰的回答:
cell.separatorInset = UIEdgeInsetsMake(0, 10000, 0, 0);
然而,这似乎对我不起作用。我不知道为什么。所以我决定使用Hiren的答案,但使用UIView而不是UIImageView,并在iOS 7风格中画出界线:
UIColor iOS7LineColor = [UIColor colorWithRed:0.82f green:0.82f blue:0.82f alpha:1.0f];
//First cell in a section
if (indexPath.row == 0) {
UIView *line = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 1)];
line.backgroundColor = iOS7LineColor;
[cell addSubview:line];
[cell bringSubviewToFront:line];
} else if (indexPath.row == [self.tableViewCellSubtitles count] - 1) {
UIView *line = [[UIView alloc] initWithFrame:CGRectMake(21, 0, self.view.frame.size.width, 1)];
line.backgroundColor = iOS7LineColor;
[cell addSubview:line];
[cell bringSubviewToFront:line];
UIView *lineBottom = [[UIView alloc] initWithFrame:CGRectMake(0, 43, self.view.frame.size.width, 1)];
lineBottom.backgroundColor = iOS7LineColor;
[cell addSubview:lineBottom];
[cell bringSubviewToFront:lineBottom];
} else {
//Last cell in the table view
UIView *line = [[UIView alloc] initWithFrame:CGRectMake(21, 0, self.view.frame.size.width, 1)];
line.backgroundColor = iOS7LineColor;
[cell addSubview:line];
[cell bringSubviewToFront:line];
}
如果使用这个,请确保在第二个If语句中插入正确的表视图高度。我希望这对某些人有用。
所有答案的代码将使单元格填充为零,而不是默认值。我在iOS 11 iPad Pro 12中看到了这个问题。”
但我有一个解决方案(“肮脏的hack”),那就是使一个空的部分,将使分隔线隐藏。
下面是我使用的代码:
typedef enum PXSettingsTableSections {
PXSettingSectionInvite = 0,
PXSettingSectionAccount,
PXSettingSectionPrivacy,
PXSettingSectionCreation,
PXSettingSectionTest,
PXSettingSectionAboutHide, // invisble section just to hide separator Line
PXSettingSectionFooterHide, // invisble section just to hide separator Line
PXSettingSectionNumItems,
} PXSettingsTableSectionsType;
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return PXSettingSectionNumItems;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
switch (section) {
case PXSettingSectionInvite: return 1;
case PXSettingSectionAccount:return (isSocialLogin) ? 1 : 2;
case PXSettingSectionPrivacy: return 1;
case PXSettingSectionCreation: return 2;
case PXSettingSectionTest: return 3;
case PXSettingSectionAboutHide: return 3;
default: return 0;
}
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
switch(section)
{
case PXSettingSectionInvite: return nil;
case PXSettingSectionAccount: return @"Account";
case PXSettingSectionPrivacy: return @"Privacy";
case PXSettingSectionCreation: return @"Someting";
case PXSettingSectionTest: return @"Test";
case PXSettingSectionAboutHide: return @" ";
case PXSettingSectionFooterHide: return @" ";
}
return nil;
}
- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
if (section == PXSettingSectionFooterHide || section == PXSettingSectionAboutHide) {
// [UIColor clearColor] will not work
[header.contentView setBackgroundColor:[UIColor whiteColor]];
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
// You can control here the size of one specific section
if(section == PXSettingSectionAboutHide){
return 0.0000001; //make it real small
}
return 45.0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
switch(indexPath.section)
{
case PXSettingSectionInvite:
return self.inviteCell;
case PXSettingSectionAccount:
if (isSocialLogin) {
return self.myWalletCell;
}
switch(indexPath.row)
{
case 0: return self.changePasswordCell;
case 1: return self.myWalletCell;
}
case PXSettingSectionPrivacy:
switch(indexPath.row)
{
case 0: return self.privateAccountCell;
}
case PXSettingSectionCreation:
switch(indexPath.row)
{
case 0: return self.videoResolutionCell;
case 1: return self.selfieMirrorCell;
}
case PXSettingSectionTest:
switch(indexPath.row)
{
case 0: return self.termsOfUseImageCell;
case 1: return self.attributionCell;
case 2: return self.aboutCell;
}
case PXSettingSectionAboutHide:{
switch(indexPath.row)
{
case 0: return self.clearCacheCell;
case 1: return self.feedbackCell;
case 2: return self.logoutCell;
}
}
}
return self.emptyCell;
}
来跟进Hiren的回答。
在ViewDidLoad和下面一行:
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
或者,如果你正在使用XIB或storyboard,将“separator”更改为“none”:
在CellForRowAtIndexPath中添加这个:
CGFloat separatorInset; // Separator x position
CGFloat separatorHeight;
CGFloat separatorWidth;
CGFloat separatorY;
UIImageView *separator;
UIColor *separatorBGColor;
separatorY = cell.frame.size.height;
separatorHeight = (1.0 / [UIScreen mainScreen].scale); // This assures you to have a 1px line height whatever the screen resolution
separatorWidth = cell.frame.size.width;
separatorInset = 15.0f;
separatorBGColor = [UIColor colorWithRed: 204.0/255.0 green: 204.0/255.0 blue: 204.0/255.0 alpha:1.0];
separator = [[UIImageView alloc] initWithFrame:CGRectMake(separatorInset, separatorY, separatorWidth,separatorHeight)];
separator.backgroundColor = separatorBGColor;
[cell addSubView: separator];
这是一个结果的例子,我显示一个动态单元格的tableview(但只有一个内容)。结果是,只有一个有分隔符,而不是所有的“虚拟”tableview自动添加填充屏幕。
编辑:对于那些不经常阅读注释的人来说,实际上有一种更好的方法,只需几行代码:
override func viewDidLoad() {
super.viewDidLoad()
tableView.tableFooterView = UIView()
}
实现这一点的最好方法是关闭默认的行分隔符,子类UITableViewCell,并添加一个自定义的行分隔符作为contentView的子视图-参见下面的自定义单元格,用于表示一个SNStock类型的对象,它有两个字符串属性,ticker和name:
import UIKit
private let kSNStockCellCellHeight: CGFloat = 65.0
private let kSNStockCellCellLineSeparatorHorizontalPaddingRatio: CGFloat = 0.03
private let kSNStockCellCellLineSeparatorBackgroundColorAlpha: CGFloat = 0.3
private let kSNStockCellCellLineSeparatorHeight: CGFloat = 1
class SNStockCell: UITableViewCell {
private let primaryTextColor: UIColor
private let secondaryTextColor: UIColor
private let customLineSeparatorView: UIView
var showsCustomLineSeparator: Bool {
get {
return !customLineSeparatorView.hidden
}
set(showsCustomLineSeparator) {
customLineSeparatorView.hidden = !showsCustomLineSeparator
}
}
var customLineSeparatorColor: UIColor? {
get {
return customLineSeparatorView.backgroundColor
}
set(customLineSeparatorColor) {
customLineSeparatorView.backgroundColor = customLineSeparatorColor?.colorWithAlphaComponent(kSNStockCellCellLineSeparatorBackgroundColorAlpha)
}
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
init(reuseIdentifier: String, primaryTextColor: UIColor, secondaryTextColor: UIColor) {
self.primaryTextColor = primaryTextColor
self.secondaryTextColor = secondaryTextColor
self.customLineSeparatorView = UIView(frame:CGRectZero)
super.init(style: UITableViewCellStyle.Subtitle, reuseIdentifier:reuseIdentifier)
selectionStyle = UITableViewCellSelectionStyle.None
backgroundColor = UIColor.clearColor()
contentView.addSubview(customLineSeparatorView)
customLineSeparatorView.hidden = true
}
override func prepareForReuse() {
super.prepareForReuse()
self.showsCustomLineSeparator = false
}
// MARK: Layout
override func layoutSubviews() {
super.layoutSubviews()
layoutCustomLineSeparator()
}
private func layoutCustomLineSeparator() {
let horizontalPadding: CGFloat = bounds.width * kSNStockCellCellLineSeparatorHorizontalPaddingRatio
let lineSeparatorWidth: CGFloat = bounds.width - horizontalPadding * 2;
customLineSeparatorView.frame = CGRectMake(horizontalPadding,
kSNStockCellCellHeight - kSNStockCellCellLineSeparatorHeight,
lineSeparatorWidth,
kSNStockCellCellLineSeparatorHeight)
}
// MARK: Public Class API
class func cellHeight() -> CGFloat {
return kSNStockCellCellHeight
}
// MARK: Public API
func configureWithStock(stock: SNStock) {
textLabel!.text = stock.ticker as String
textLabel!.textColor = primaryTextColor
detailTextLabel!.text = stock.name as String
detailTextLabel!.textColor = secondaryTextColor
setNeedsLayout()
}
}
要禁用默认的行分隔符,请使用tableView。separatorStyle = UITableViewCellSeparatorStyle.None;消费者方面相对简单,见下面的例子:
private func stockCell(tableView: UITableView, indexPath:NSIndexPath) -> UITableViewCell {
var cell : SNStockCell? = tableView.dequeueReusableCellWithIdentifier(stockCellReuseIdentifier) as? SNStockCell
if (cell == nil) {
cell = SNStockCell(reuseIdentifier:stockCellReuseIdentifier, primaryTextColor:primaryTextColor, secondaryTextColor:secondaryTextColor)
}
cell!.configureWithStock(stockAtIndexPath(indexPath))
cell!.showsCustomLineSeparator = true
cell!.customLineSeparatorColor = tintColor
return cell!
}
