如何从 UIScrollview 获取 UITextview 覆盖的点击位置
大家好...
我有一个文本视图作为滚动视图的子视图，文本视图覆盖了所有滚动视图区域。 我想在滚动视图中获取位置点击，但文本视图没有通过它 情况是，如果我点击文本视图，滚动视图中也会检测到点击。 我可以这样做吗？
这是我的实现：
-(void)viewWillAppear:(BOOL)animated{
UIGestureRecognizer *tapScroll = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
//tapScroll.numberOfTapsRequired = 2;
[self.scrollView addGestureRecognizer:tapScroll];
self.tapGesture = (UITapGestureRecognizer *)tapScroll;
tapScroll.delegate = self;
[tapScroll release];
}
-(void)handleTap:(UITapGestureRecognizer *)recognizer{
NSLog(@"handle tap");
location = [recognizer locationInView:self.scrollView];
[self.textView becomeFirstResponder];
NSLog(@"location tap x : %f, y : %f", location.x, location.y);
if (location.y < self.view.frame.size.height - keyBoardBounds.size.height) {
NSLog(@"HEIGHT : %f", self.view.frame.size.height - keyBoardBounds.size.height);
[self.scrollView setContentOffset:CGPointZero animated:YES];
}else {
[self.scrollView setContentOffset:CGPointMake(0, location.y/2) animated:YES];
}
}
我无法获取点击位置，因为文本视图没有通过它，有人可以帮助我吗？
