我在 iOS5 中工作，显然我应该能够使用 scrollView.pinchGestureRecognizer 控制或至少抑制 UIScrollView 的内部捏合手势识别器。
但是，我的代码似乎不起作用。识别器不会将我的班级视为代表，也不会等待我的旋转手势识别器失败。我该怎么做才能优先考虑旋转手势，然后再考虑捏合？
更准确地说，我遇到的问题是同时旋转和缩放的视图“飞离屏幕”朝向左下角，再也看不到了。
-(void)setup scrollViews
{
[tempScrollView.pinchGestureRecognizer requireGestureRecognizerToFail:rotationRecognizer];
tempScrollView.pinchGestureRecognizer.delegate = self;
tempScrollView.maximumZoomScale = 4.0;
tempScrollView.minimumZoomScale = 0.25;
//
tempScrollView.delegate = self;
}
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}
-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
if([gestureRecognizer isEqual:rotationRecognizer])
{
NSLog(@"Rotation gesture");
}else {
NSLog(@"Other gesture: %@", [gestureRecognizer class]);
}
return YES;
}
- (IBAction)rotateView:(id)sender {
if([sender isKindOfClass:[UIRotationGestureRecognizer class]])
{
UIRotationGestureRecognizer* recognizer = sender;
float recognizerRotation = [recognizer rotation];
CGAffineTransform transform = CGAffineTransformMakeRotation(recognizerRotation);
activeView.transform = transform;
}
}
