Ich habe eine Ansichtshierarchie, die ungefähr so aussieht:
UIView (A)
UIView > UIImageView
UIView > UIView (B)
UIView > UIView (B) > Rounded Rect Button
UIView > UIView (B) > UIImageView
UIView > UIView (B) > UILabel
Ich habe Gestenerkenner an meine UIView (B) angehängt. Das Problem, mit dem ich konfrontiert bin, ist, dass ich keine Aktionen für den abgerundeten Rechteck-Button bekomme, der sich in der UIView befindet (B). Der SingleTap-Gestenerkenner erfasst / überschreibt das Touch Up Inside-Ereignis der Schaltfläche.
Wie kann ich es zum Laufen bringen? Ich dachte, dass die Hierarchie der Antwortketten sicherstellen wird, dass das Tastenberührungsereignis bevorzugt wird und ausgelöst wird! Was vermisse ich?
Hier ist ein verwandter Code:
#pragma mark -
#pragma mark View lifecycle (Gesture recognizer setup)
- (void)viewDidLoad {
[super viewDidLoad];
// double tap gesture recognizer
UITapGestureRecognizer *dtapGestureRecognize = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTapGestureRecognizer:)];
dtapGestureRecognize.delegate = self;
dtapGestureRecognize.numberOfTapsRequired = 2;
[self.viewB addGestureRecognizer:dtapGestureRecognize];
// single tap gesture recognizer
UITapGestureRecognizer *tapGestureRecognize = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapGestureRecognizer:)];
tapGestureRecognize.delegate = self;
tapGestureRecognize.numberOfTapsRequired = 1;
[tapGestureRecognize requireGestureRecognizerToFail:dtapGestureRecognize];
[self.viewB addGestureRecognizer:tapGestureRecognize];
// add gesture recodgnizer to the grid view to start the edit mode
UILongPressGestureRecognizer *pahGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressGestureRecognizerStateChanged:)];
pahGestureRecognizer.delegate = self;
pahGestureRecognizer.minimumPressDuration = 0.5;
[self.viewB addGestureRecognizer:pahGestureRecognizer];
[dtapGestureRecognize release];
[tapGestureRecognize release];
[pahGestureRecognizer release];
}
