如果将UIView添加为子视图,则UIButton目标不起作用

我有一个UIButton.它有两个子视图.然后我打电话给:

[createButton addTarget:self action:@selector(openComposer) forControlEvents:UIControlEventTouchUpInside];

如果我点击UIButton那些未被覆盖的部分,但是它的一个子视图,它可以正常工作.但是,如果我点击其中一个子视图,则不会触发该操作.

在两个子视图中,我已经.userInteractionEnabled设置为YES.

这两个子视图都是UIViews带有frame和的backgroundColor.

如何让水龙头"通过" UIView并进入UIButton？

谢谢

编辑:我需要使用UIControlEvents因为我需要UIControlEventTouchDown.

编辑2:

这是按钮的代码.

@interface CreateButton ()

@property (nonatomic) Theme *theme;
@property (nonatomic) UIView *verticle;
@property (nonatomic) UIView *horizontal;
@property (nonatomic) BOOL mini;

@end

@implementation CreateButton

    if (! _verticle) {
        _verticle = [[UIView alloc] init];
        _verticle.backgroundColor = [self.theme colorForKey:@"createButtonPlusBackgroundColor"];
        _verticle.userInteractionEnabled = NO;
    }
    return _verticle;
}

    if (! _horizontal) {
        _horizontal = [[UIView alloc] init];

设置userInteractionEnabled到NO你的子视图,让触摸通过他们到您的按钮.

还要确保_verticle.userInteractionEnabled = NO;为您的horizontal房产改变您的懒人装载机,_horizontal.userInteractionEnabled = NO;因为我认为这是一个错字.
