我想在单击类的对象时删除手势
I want to remove gesture when i click on object of a class
问：
从我的角度来看，我将尝试以下代码，但它不起作用。
- (void) handleTouch:(UITapGestureRecognizer *) gesture
{
CGPoint touchPoint = [gesture locationInView:self.view];
NSArray *viewsAtPoint = [self viewsAtPoint:touchPoint];
for(TheifView * aView in viewsAtPoint)
{
[aView removeFromSuperview];
}
}
- (void) registerGesture
{
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouch:)];
tapGesture.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tapGesture];
}

将标签放入 ThiefView...说 111。然后，您可以识别它并从 self.view 中删除。如果这不是您期望的答案，请用清晰的描述进行解释。
用于从视图中删除手势。
for (UIGestureRecognizer *recognizer in self.view.gestureRecognizers) {
if ([recognizer isKindOfClass:[UITapGestureRecognizer class]]) {
[self.view removeGestureRecognizer:recognizer];
}
}
用于从视图中删除 ThiefView
for (UIView *subview in self.view.subviews) {
if (subview.tag==111) {
[subview removeFromSuperview];
}
}
