IOS开发--给UIImageView添加touch事件

Add Tap gesture UITapGestureRecognizer to myImageView view (type of UIImageView).

UITapGestureRecognizer *myTapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(gestureTapEvent:)]; myImageView.userInteractionEnabled = YES;[myImageView addGestureRecognizer:myTapGesture];[myTapGesture release];    

Implement gestureTapEvent: method to receive the touch event.

-(void)gestureTapEvent:(UITapGestureRecognizer *)gesture {

UIImageView* myImageView = (UIImageView*)gesture.view ;
}

Then when you implement your imageViewClicked method, you can get the tapped ImageView using the view property of the GestureRecognizer. Starting from that, you can for example:
use the tag of your imageView (if you affected it in your tableView:cellForRowAtIndexPath:method) to retrieve the tag and do whatever you want with it (depending on what you affected it to, for example you may have set imageView.tag = indexPath.row intableView:cellForRowAtIndexPath: and get that indexPath row back then)
Go thru the superviews of the imageView up to the UITableViewCell, then ask for its indexPath to get it back and do whatever you want with it.
Example:
-(void)imageViewClicked:(UITapGestureRecognizer*)gestRecognizer{    UIImageView* iv = (UIImageView*)gestRecognizer.view;    NSInteger tag = iv.tag; // then do what you want with this    // or get the cell by going up thru the superviews until you find it    UIView* cellView = iv;    while(cellView && ![cellView isKindOfClass:[UITableViewCell class]])        cellView = cellView.superview; // go up until you find a cell    // Then get its indexPath    UITableViewCell* cell = (UITableViewCell*)cellView;    NSIndexPath* indexPath = [self.tableView indexPathForCell:cell];}
