已经搜索了一些可能的修复,但都没有解决我的问题.
我一直在点击uitableview中的单元格,而不是单击其中的按钮.
这是我的代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.backgroundColor = [UIColor blackColor];
UIView *v = nil;
NSArray *array = [cell subviews];
for (v in array) {
NSLog(@"%@",[v class]);
if( [v isKindOfClass:[UIView class]] ){
[v removeFromSuperview];
}
}
//tb
if (tableView == self.tb) {
v = [[UIView alloc] initWithFrame: CGRectMake(0, 0, self.tb.bounds.size.width, 120.0)];
if([feeds count]>0){
UIImageView *box=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"statusBox.png"]];
box.userInteractionEnabled = YES;
[v addSubview:box];
AsyncImageView *imageView1 = [[AsyncImageView alloc] initWithFrame:CGRectMake(10, 20.0f, 34.0f, 34.0f)];
imageView1.contentMode = UIViewContentModeScaleAspectFill;
imageView1.clipsToBounds = YES;
//cancel loading previous image for cell
[[AsyncImageLoader sharedLoader] cancelLoadingImagesForTarget:imageView1];
if (users1 != nil && users1.imagelink != nil && (id) users1.imagelink != [NSNull null]){
imageView1.imageURL = [NSURL URLWithString:users1.imagelink];
}
else{
imageView1.image=[UIImage imageNamed:@"default_ProfilePic.png"];
}
UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myFunction:)];
tapped.numberOfTapsRequired = 1;
[imageView1 addGestureRecognizer:tapped];
[tapped release];
imageView1.userInteractionEnabled = NO;
[v addSubview:imageView1];
UIFont *font = [UIFont fontWithName:@"TrebuchetMS-Bold" size:11];
UILabel *descLabel1 = [[UILabel alloc] initWithFrame: CGRectMake(52, 23, 160, 48)];
descLabel1.text = [NSString stringWithFormat:@"%@ %@",users1.userfirstn,users1.userlastn];
descLabel1.textColor = [UIColor blackColor];
descLabel1.font = font;
descLabel1.adjustsFontSizeToFitWidth=YES;
descLabel1.numberOfLines = 0;
CGSize expectedLabelSize = [descLabel1.text sizeWithFont:descLabel1.font
constrainedToSize:descLabel1.frame.size
lineBreakMode:UILineBreakModeWordWrap];
CGRect newFrame = descLabel1.frame;
newFrame.size.height = expectedLabelSize.height;
descLabel1.frame = newFrame;
descLabel1.numberOfLines = 0;
descLabel1.userInteractionEnabled = NO;
[v addSubview:descLabel1];
UILabel *descLabel2= [[UILabel alloc] initWithFrame: CGRectMake(52, 43, 200, 48)];
StatusClass *stat1=[feeds objectAtIndex:indexPath.row];
descLabel2.text = [stat1 statcreate];
descLabel2.textColor = [UIColor blackColor];
descLabel2.font = font;
descLabel2.adjustsFontSizeToFitWidth=YES;
descLabel2.numberOfLines = 0;
CGSize expectedLabelSize2 = [descLabel2.text sizeWithFont:descLabel2.font
constrainedToSize:descLabel2.frame.size
lineBreakMode:UILineBreakModeWordWrap];
CGRect newFrame2 = descLabel2.frame;
newFrame2.size.height = expectedLabelSize2.height;
descLabel2.frame = newFrame2;
descLabel2.numberOfLines = 0;
descLabel2.userInteractionEnabled = NO;
[v addSubview:descLabel2];
UILabel *descLabel3= [[UILabel alloc] initWithFrame: CGRectMake(10, 63, 280, 80)];
StatusClass *stat=[feeds objectAtIndex:indexPath.row];
descLabel3.text = [stat stattext];
descLabel3.textColor = [UIColor blackColor];
descLabel3.font = font;
descLabel3.adjustsFontSizeToFitWidth=YES;
descLabel3.numberOfLines = 0;
descLabel3.userInteractionEnabled = NO;
[v addSubview:descLabel3];
//comment button
UIButton *buttonC = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[buttonC addTarget:self action:@selector(sendComment:) forControlEvents:UIControlEventTouchUpInside];
[buttonC setImage:[UIImage imageNamed:@"comment.png"] forState:UIControlStateNormal];
buttonC.frame = CGRectMake(2, 160, 145, 35);
buttonC.userInteractionEnabled = YES;
[v addSubview:buttonC];
//share button
UIButton *buttonS = [UIButton buttonWithType:UIButtonTypeRoundedRect];
buttonS.tag = indexPath.row;
[buttonS addTarget:self action:@selector(sendShare:) forControlEvents:UIControlEventTouchUpInside];
[buttonS setImage:[UIImage imageNamed:@"share.png"] forState:UIControlStateNormal];
buttonS.frame = CGRectMake(150, 160, 140, 35);
buttonS.userInteractionEnabled = YES;
[v addSubview:buttonS];
}
v.userInteractionEnabled = YES;
[cell addSubview:v];
}
return cell;
}
我也尝试了UITapGestureRecognizer按钮,仍然没有工作.
谢谢.

我对这个问题感到困惑....
我设法通过在一个项目上执行此操作来解决此问题:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("RegCell", forIndexPath: indexPath) as! CustomCell
cell.contentView.userInteractionEnabled = false // <<-- the solution
return cell
}
但同样不适用于不同的项目.我不知道为什么...

还有另外一个像这样的问题的潜在原因,那就是UITableViewCells现在有了contentView.这可以并将放置在自定义表格视图单元格中的其他视图之前,以便拾取触摸并检测单元格选择.这样做可能会阻止其后面的任何视图的触摸.在使用笔尖创建单元格时,我特别注意到这种烦恼.
处理此问题的可接受方法是确保所有子视图不是添加到tableview单元本身,而是添加到其中contentView.这是一个只读属性,可在某些情况下调整自己的帧,例如,当侧向滑动以显示删除按钮时,或在编辑模式期间.因此,您应确保您添加到的任何项目contentView都具有智能大小并具有正确的调整大小行为.
还要注意,通过添加单元格contentView,您可以自己阻止对它的触摸,从而防止选择单元格.我个人尝试不允许在包含具有自定义用户启用控件的单元格的tableviews中选择单元格.它只会导致混乱和尴尬的界面.事实上,我正在认真考虑用UITableViews我的未来项目替换所有项目UICollectionViews,这些项目更具适应性.

我是这样做的：
let plusButton: UIButton = {
let v = UIButton()
v.setImage(plusImg, for: .normal)
v.tintColor = .dark
v.translatesAutoresizingMaskIntoConstraints = false
// adding targets here did not work
v.addTarget(self, action: #selector(plusButtonHandler), for: .touchUpInside)
return v
}()
并且似乎调用addTarget闭包内部的方法不起作用。
当我将addTarget方法分解出来并将其放入初始化程序时，一切正常！

在我的情况下，我尝试通过 将 UIButton 直接添加到单元格self.addSubview(myButton)，所以我更改为self.contentView.addSubview(myButton)并且它起作用了
似乎contentView是在前面myButton所以按钮不会收到点击手势。
UITableViewCell 默认处理所有手势。设置cell.selectionStyle = UITableViewCellSelectionStyleNone;以使其禁用默认行为。
