UIButton在UIScrollView中不起作用 [英] UIButton does not work when it in UIScrollView
问题描述
我的观点结构:
UITableView
UITableViewCell
UIScrollView
CustomView
UIButton
问题是当我触摸它时UIButton不起作用。
我用代码创建它:
The problem is UIButton doesn't work when I touch it. I create it with code:
btn = [[UIButton alloc] init];
[btn setImage:image forState:UIControlStateNormal];
[btn addTarget:self action:@selector(tileTouchUpInside) forControlEvents:UIControlEventTouchUpInside];
btn.layer.zPosition = 1;
[self addSubview:btn];
我还添加了这个:
scroll.delaysContentTouches = NO;
scroll.canCancelContentTouches = NO;
但我的按钮无论如何都不起作用。我无法取消内容或为UITableView设置延迟,因为如果我设置它,UITableView会停止垂直滚动。
But my button doesn't work anyway. I can't cancelContentTouches or set delay for UITableView because if I set it, UITableView stop scrolling verticaly.
感谢您的帮助!
推荐答案
使用
- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
return NO;
}
如果您没有收到该消息,请设置:
If you are not getting that message, set:
scrollView.delaysContentTouches = NO;
问题是因为 touchesShouldCancelInContentView
的方式默认情况下,只有当子视图是UIControl时才返回NO,但是你的按钮隐藏在CustomView中,而不是。
The problem is because of the way touchesShouldCancelInContentView
behaves by default, it returns NO only if the subview is an UIControl, but your button is hidden inside the CustomView which isn't.
