我已经创建了一个自定义UITableViewCell。表视图很好地显示了数据。我陷入的是当用户触摸tableview的单元格时,然后我想显示单元格的背景颜色,而不是默认的[蓝色]值,以突出显示单元格的选择。 我使用这段代码,但什么都没有发生:
cell.selectedBackgroundView.backgroundColor=[UIColor blackColor];

对于Swift 3.0:
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = super.tableView(tableView, cellForRowAt: indexPath)
cell.contentView.backgroundColor = UIColor.red
}

I've got a slightly different approach than everyone else that reflects the selection on touch rather than after being selected. I have a subclassed UITableViewCell. All you have to do is set the background color in the touch events, which simulates selection on touch, and then set the background color in the setSelected function. Setting the background color in the selSelected function allows for deselecting the cell. Make sure to pass the touch event to the super, otherwise the cell won't actually act as if its selected.
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
self.backgroundColor = UIColor(white: 0.0, alpha: 0.1)
super.touchesBegan(touches, withEvent: event)
}
override func touchesCancelled(touches: NSSet!, withEvent event: UIEvent!) {
self.backgroundColor = UIColor.clearColor()
super.touchesCancelled(touches, withEvent: event)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
self.backgroundColor = selected ? UIColor(white: 0.0, alpha: 0.1) : UIColor.clearColor()
}
在Swift 4中,你还可以全局设置你表格单元格的背景色(从这里取):
let backgroundColorView = UIView()
backgroundColorView.backgroundColor = UIColor.red
UITableViewCell.appearance().selectedBackgroundView = backgroundColorView
如果你正在使用一个自定义的TableViewCell,你也可以覆盖awakeFromNib:
override func awakeFromNib() {
super.awakeFromNib()
// Set background color
let view = UIView()
view.backgroundColor = UIColor.redColor()
selectedBackgroundView = view
}
根据UITableView中选定单元格的自定义颜色,根据Maciej Swic的答案,很棒的解决方案
为了补充这一点,你在Cell配置中声明Swic的答案通常如下:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
为了增加效果,您可以使用RGB值来实现自定义颜色外观,而不是系统颜色。在我的代码中,我是这样实现的:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
}
static NSString *CellIdentifier = @"YourCustomCellName";
MakanTableCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Configure the cell...
if (cell == nil) {
cell = [[[NSBundle mainBundle]loadNibNamed:@"YourCustomCellClassName" owner:self options:nil]objectAtIndex:0];
}
UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor colorWithRed:255.0/256.0 green:239.0/256.0 blue:49.0/256.0 alpha:1];
bgColorView.layer.cornerRadius = 7;
bgColorView.layer.masksToBounds = YES;
[cell setSelectedBackgroundView:bgColorView];
return cell;
}
如果这对你也有用,请告诉我。你可以在选定单元格的角落上打乱拐角半径的数值。
为所有单元格添加背景(使用Maciej的答案):
for (int section = 0; section < [self.tableView numberOfSections]; section++) {
for (int row = 0; row < [self.tableView numberOfRowsInSection:section]; row++) {
NSIndexPath* cellPath = [NSIndexPath indexPathForRow:row inSection:section];
UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:cellPath];
//stuff to do with each cell
UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor redColor];
[cell setSelectedBackgroundView:bgColorView];
}
}
