Detecting taps in uiimageview inside uiscrollview

Question

I have a UIScrollView with multiple UIImageViews in it created like this. ``` frame = [[UIImageView alloc] initWithImage:bg]; frame.frame = CGRectMake(FRAME_SEPARATOR + numPage*1024 + numColumn*(FRAME_SEPARATOR+230), 10 +numRow*(FRAME_SEPARATOR+145), 230, 145); UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped:)]; [frame addGestureRecognizer:tap]; [tap release]; [scroll addSubView:frame]; ``` The problem is that imageTapped is not being called when tapping over an image. If I add the gesture recognizer to the scrollview like this: ``` UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped:)]; [scroll addGestureRecognizer:tap]; [tap release]; ``` imageTapped is called. How can I detect the taps over the UIImageViews? Thanks

Accepted Answer

Make sure userInteractionEnabled is set to YES on the UIImageView:

```
frame.userInteractionEnabled = YES;
```

I'd also recommend using a different name for the UIImageView variable (eg. imageView instead of frame). Otherwise, you can easily confuse it with the view's frame property.
