I added two uiimageview
s, one on another subview uiview
(imageview1,imageview2
). In the first view the top uiimageview
is hidden(imageview2
) and in the second view the bottom imageview
is hidden(imageview1
).
Allocating tap gesture:
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)]; UITapGestureRecognizer *singleTap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)];
Set user interaction for both uiimageview to YES.
[singleTap setNumberOfTapsRequired:1]; [singleTap1 setNumberOfTapsRequired:1];
// adding gesture to uiimageview
Add tap gesture recognizer and selector respectively.
[imageview1 addGestureRecognizer:singleTap]; [imageview2 addGestureRecognizer:singleTap1];
But my taps are not recognized.
Can any one tell me where the mistake is?
Open the Library, look for "Tap Gesture Recognizer" object. Drag the object to your storyboard, and set the delegate to the image you want to trigger actions. Then go to the view controller, drag the same object to set the IBAction.
Adding a Tap Gesture Recognizer in Interface Builder You don't need to switch between the code editor and Interface Builder. Open Main. storyboard and drag a tap gesture recognizer from the Object Library and drop it onto the view we added earlier. The tap gesture recognizer appears in the Document Outline on the left.
Try setting setUserInteractionEnabled:YES
before adding gesture recognizer.
[imageview1 setUserInteractionEnabled:YES] [imageview2 setUserInteractionEnabled:YES] [imageview1 addGestureRecognizer:singleTap]; [imageview2 addGestureRecognizer:singleTap1];
Update:
After the comment you have made I suggest you bring your views to the top before detecting the tap event. Because parent imageView is above and catches these taps.
[yourparentview bringSubviewToFront:imageview1]; [yourparentview bringSubviewToFront:imageview2];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)]; singleTap.numberOfTapsRequired = 1; singleTap.numberOfTouchesRequired = 1; singleTap.delegate = self; [imageview1 addGestureRecogniser:singleTap]; [singleTap1 release]; imageview1.userInteractionEnabled = YES; //disabled by default
