You can use a UIGestureRecognizer to detect touches on the map view. Instead of a single tap, however, I would suggest looking for a double tap (UITapGestureRecognizer) or a long press (UILongPressGestureRecognizer). A single tap might interfere with the user trying to single tap on the pin or callout itself. In the place where you … Read more
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];
I had the same problem, and I finally had a revelation 😛 It was like simultaneous gesture rencognizers on uiPickerView don’t work. so I use the gesture delegate < UIGestureRecognizerDelegate> with // add tap gesture UITapGestureRecognizer* gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(pickerViewTapGestureRecognized:)]; [picker addGestureRecognizer:gestureRecognizer]; gestureRecognizer.delegate = self; with -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{ // return return … Read more
This method does not require subclassing anything. You just add a UILongPressGestureRecognizer to the view and set the minimumPressDuration to zero. Then you check the state when the gesture events are called to see if the touch event is beginning or ending. Here is the entire project code for the example image above. import UIKit … Read more
This should solve your problem. Detect touch event on UIScrollView AND on UIView’s components [which is placed inside UIScrollView] The idea is to tell the gesture recognizer to not swallow up the touch events. To do this you need to set singleTap’s cancelsTouchesInView property to NO, which is YES by default. UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer … Read more
This is a step by step guide on how to implement gesture recognizers in your class: Conform your class to UIGestureRecognizerDelegate protocol. Instantiate the gesture recognizer. For example, to instantiate a UITapGestureRecognizer, we will do: UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapFrom:)]; Here, action is the selector which will handle the gesture. Here, our selector … Read more
UINavigationBar does not expose its internal view hierarchy. There is no supported way to get a reference to the UILabel that displays the title. You could root around in its view hierarchy “manually” (by searching through its subviews), but that might stop working in a future iOS release because the view hierarchy is private. One … Read more
Define your target selector(highlightLetter:) with argument as UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter:)]; Then you can get view by – (void)highlightLetter:(UITapGestureRecognizer*)sender { UIView *view = sender.view; NSLog(@”%d”, view.tag);//By tag, you can find out where you had tapped. }
The UIGestureRecognizer is a red herring I think. In the end to solve this I overrode the pointInside:withEvent: method of my UIView: – (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event { BOOL pointInside = NO; if (CGRectContainsPoint(imageView.frame, point) || expanded) pointInside = YES; return pointInside; } This causes the view to trap all touches if you touch either the … Read more
