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。

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!
}

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
}
如果接受的答案不成立,你可以试试这个:
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
return 0.01f; }
太棒了;)
当我使用扩展和调用layoutSubviews()立即更新布局视图时,它为我工作。
extension UITableViewCell {
func removeSeparator() {
separatorInset = UIEdgeInsetsMake(0, bounds.size.width, 0, 0)
}
}
override func layoutSubviews() {
super.layoutSubviews()
removeSeparator()
}
iphone的宽度是320。因此,在单元格属性中为separatorInset设置左右值,大于320的一半。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellId = @"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
NSInteger lastRowIndexInSection = [tableView numberOfRowsInSection:indexPath.section] - 1;
if (row == lastRowIndexInSection) {
CGFloat halfWidthOfCell = cell.frame.size.width / 2;
cell.separatorInset = UIEdgeInsetsMake(0, halfWidthOfCell, 0, halfWidthOfCell);
}
}
