我有一个UIButton
。它有两个子视图。然后我打电话:
[createButton addTarget:self action:@selector(openComposer) forControlEvents:UIControlEventTouchUpInside];
如果我点击UIButton
未涵盖但其子视图之一,它工作正常。但是,如果我点击其中一个子视图,它不会触发该操作。
在两个子视图上,我都有.userInteractionEnabled
set to YES
.
两个子视图都是普通的UIViews
与一个frame
and backgroundColor
.
如何让水龙头“通过”UIView
并到UIButton
?
Thanks
EDIT:我需要使用 UIControlEvents 因为我需要 UIControlEventTouchDown。
EDIT 2:
这是按钮的代码。
@interface CreateButton ()
@property (nonatomic) Theme *theme;
@property (nonatomic) UIView *verticle;
@property (nonatomic) UIView *horizontal;
