如何在 UITableViewCellStyleSubtitle 样式中检测对 UITableViewCell 对象的 UIImageView 的触摸 [英] How to detect touches on UIImageView of UITableViewCell object in the UITableViewCellStyleSubtitle style

问题描述

我在 UITableViewCellStyleSubtitle样式(即左侧的图像视图，粗体文本标签和详细文本标签下方)来创建我的表格.现在我需要检测对 UIImageView 的触摸，还需要知道单击图像视图的索引路径/单元格.我尝试使用

I am using the UITableViewCell object in the UITableViewCellStyleSubtitle style (i.e an image view on the left, text label in bold and under that a detail text label) to create my table. Now I need to detect touches on the UIImageView and also to know the indexpath/cell in which the image view was clicked. I tried using

cell.textLabel.text = @"Sometext";
NSString *path = [[NSBundle mainBundle] pathForResource:@"emptystar1" ofType:@"png"];
UIImage *theImage = [UIImage imageWithContentsOfFile:path];
cell.imageView.image = theImage;
cell.imageView.userInteractionEnabled = YES; 

但它不起作用.每当单击图像时，都会调用 didSelectRowAtIndexPath:.我不想创建一个单独的 UITableViewCell 并向其添加自定义按钮.有什么方法可以检测到 UIImageView 本身的触摸?

But it's not working. Whenever the image is clicked, didSelectRowAtIndexPath: is called. I don't want to create a separate UITableViewCell and add a custom button to it. Is there any way to detect touches on the UIImageView itself?

推荐答案

在你的 cellForRowAtIndexPath 方法中添加这段代码

In your cellForRowAtIndexPath method add this code

cell.imageView.userInteractionEnabled = YES;
cell.imageView.tag = indexPath.row;

UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myFunction:)];
tapped.numberOfTapsRequired = 1;
[cell.imageView addGestureRecognizer:tapped];   
[tapped release];

然后要检查哪个 imageView 被点击，检查 selector 方法中的标志

And then to check which imageView was clicked, check the flag in selector method

-(void)myFunction :(id) sender
{
    UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender;
    NSLog(@"Tag = %d", gesture.view.tag);
}
