Первоначально я не хотел делать это таким образом, но, похоже, до сих пор он работал без проблем (взято из данного сообщения devforums):
Добавьте UIGestureRecognizerDelegate в свой заголовок.
Теперь добавьте проверку номера версии ... Если мы на iOS 4, мы можем сделать это:
if (NSFoundationVersionNumber >= 678.58){
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchGestureCaptured:)];
pinch.delegate = self;
[mapView addGestureRecognizer:pinch];
[pinch release];
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panGestureCaptured:)];
pan.delegate = self;
[mapView addGestureRecognizer:pan];
[pan release];
}
Добавить методы делегата для обработки жестов:
#pragma mark -
#pragma mark Gesture Recognizers
- (void)pinchGestureCaptured:(UIPinchGestureRecognizer*)gesture{
if(UIGestureRecognizerStateEnded == gesture.state){
///////////////////[self doWhatYouWouldDoInRegionDidChangeAnimated];
}
}
- (void)panGestureCaptured:(UIPanGestureRecognizer*)gesture{
if(UIGestureRecognizerStateEnded == gesture.state){
///////////////////[self doWhatYouWouldDoInRegionDidChangeAnimated];
}
}
-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{
return YES;
}
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch: (UITouch *)touch{
return YES;
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;
}
