我在iOS5中工作，顯然我應該能夠使用scrollView.pinchGestureRecognizer控制或至少抑制UIScrollView的內部捏手勢識別器。iPhone iOS如何在啓用縮放時使UIScrollView與UIRotationGestureRecognizer一起使用？
但是，我的代碼似乎不工作。識別器不會將我的課程視爲委託，並且不會等待我的旋轉手勢識別器失敗。我能做些什麼來使旋轉手勢成爲優先事項，之後會考慮捏？
更確切地說，我運行的問題是，同時旋轉和縮放的視圖「飛出屏幕」朝向左下角，永遠不會再被看到。
-(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;
}
}
