UIView 内的 UIButton，带有showTouchWhenHighlighted 辉光被超级视图剪裁

发布于 2024-11-01 02:04:54 字数 459 浏览 4 评论 0原文

我使用的方法可能有点错误，如果是这样，也许有人可以建议......但无论如何，我用于创建响应程序小部件的模式涉及添加一个不可见的 UIButtonTypeCustom 来填充UIView 的边界，以便向任何视图添加向后兼容的按钮行为。对于我的需求，这效果非常好。为了稍微改善使用此混合按钮的用户体验，我将按钮的showsTouchWhenHighlighted设置为YES。这工作正常，但按钮的“发光”被按钮的父 UIView 剪切。我试过了；

button.layer.masksToBounds = NO;
button.clipsToBounds = NO;
parentView.layer.masksToBounds = NO;
parentView.clipsToBounds = NO;

但这些都不允许发光脱离父视图的边界。这是一个相当小的外观问题，但我认为让这个工作看起来更好

希望有人可以提供帮助！谢谢

it's possible the approach i'm using with this might be a little wrong, and if so perhaps someone can advise... but in any case, a pattern i've got into for creating responder widgets involves adding an invisible UIButtonTypeCustom that fills the bounds of a UIView in order to add backwards-compatible button behaviour to any view. for my needs, this works perfectly well. in order to slightly improve the user experience of using this hybrid button, i set showsTouchWhenHighlighted to YES for the button. this works fine, but the "glow" of the button is clipped by the button's parent UIView. i've tried;

button.layer.masksToBounds = NO;
button.clipsToBounds = NO;
parentView.layer.masksToBounds = NO;
parentView.clipsToBounds = NO;

but none of these allow the glow to escape the bounds of the parentView. it's quite a minor cosmetic issue, but i think it would look nicer to get this working

hope someone can help! thanks

我使用这样的代码，并且发光不会被父级剪辑 - 经过验证和测试。

UIButton myButton = [[UIButton alloc] init....];
[parentView addSubview:myButton];
myButton.showsTouchWhenHighlighted = YES;
parentView.clipsToBounds = NO;

无需在按钮上设置 .clipsToBounds = NO；默认值已经是NO。

当您设置属性时，您是否检查过 parentView 是否为非零？还要检查层次结构中是否没有另一个可能会剪切发光效果的 UIView。

I use code like this, and the glow is not clipped by the parent - verified and tested.

UIButton myButton = [[UIButton alloc] init....];
[parentView addSubview:myButton];
myButton.showsTouchWhenHighlighted = YES;
parentView.clipsToBounds = NO;

No need to set .clipsToBounds = NO on the button; the default is already NO.

Have you checked that parentView is non-nil when you're setting the properties? Check also that there isn't another UIView further up in the hierarchy that might be clipping the glow effect.
