在我的应用程序中,我有一个 tapGesture、panGesture、rotationGesture 和 pinchGesture。 tapGesture 是所有手势的起点,它向我展示了选择了哪个 subview 。
当我输入一个按钮来处理 ImagePicker 后, subview 仍然处于选中状态,因此它仍在处理手势。
我的问题:是否有停止处理手势的声明?
编辑
我不需要 gestureRecognizer,因此我将它们置于非事件状态:
panRecognizer.enabled = NO;
pinchRecognizer.enabled = NO;
rotationRecognizer.enabled = NO;
因此,如果我需要它们,我希望在处理 tapRecognizer 时让它们工作, 但此处识别器不会从非事件状态变为事件状态。
[panRecognizer isEnabled];
pinchRecognizer.enabled = YES;
rotationRecognizer.enabled = YES;

我的 View 是一个 ViewController, subview 在 imageView 上。
识别器被分配给 self.imageView。
在第一种方法中,我禁用了识别器,在第二种方法中,我启用了它们
- (IBAction)photo: (id) sender {
panRecognizer.enabled = NO;
pinchRecognizer.enabled = NO;
rotationRecognizer.enabled = NO;
UIImagePickerController* picker = [[UIImagePickerController alloc]init];
picker.delegate = self;
picker.allowsEditing = NO;
@try {
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
@catch (NSException * e) {
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"Error" message:@"Camera is not available"
delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease];
[alert show];
}
[picker release];
}
- (IBAction)oneTap: (UIGestureRecognizer*)gestureRecognizer {
NSLog(@"oneTap");
float differenz = 2000;
[panRecognizer isEnabled];
pinchRecognizer.enabled = YES;
rotationRecognizer.enabled = YES;
for (UIView* const subview in array) {
subview.opaque = YES;
CGPoint const point = [gestureRecognizer locationInView:self.imageView];
float zwischenS = sqrt(powf(point.x - subview.frame.origin.x,2)) + sqrt(powf(point.y - subview.frame.origin.y,2));
if (differenz > zwischenS ) {
differenz = sqrt(powf(point.x - subview.frame.origin.x,2)) + sqrt(powf(point.y - subview.frame.origin.y,2));
newView.layer.borderColor = [[UIColor clearColor]CGColor];
newView = subview;
subview.layer.borderColor = [[UIColor whiteColor]CGColor];
subview.layer.borderWidth = 3.0f;
[imageView bringSubviewToFront: subview];
}
}
}
我的错误是什么?
