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

问题描述

我在 UITableViewCell 对象TableView_iPhone / TableViewCells / TableViewCells.html> UITableViewCellStyleSubtitle
样式（即左侧的图像视图，粗体的文本标签，文本标签）来创建我的表。现在我需要检测 UIImageView 上的触摸，并且还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; 

但它不工作。每当图像被点击， didSelectRowAtIndexPath：被调用。我不想创建一个单独的 UITableViewCell 并添加一个自定义按钮。有没有办法检测 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 cellForRowAtIndexPath 方法中添加此代码

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];

然后检查哪个 imageView ，检查选择器方法中的标志

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);
}
