添加子视图后无法单击 UIButton [英] Can't click on UIButton after add a subview

问题描述

我正在使用一种方法为我的按钮添加阴影.问题是在那之后，我无法点击它们.我将 userinteractionenabled 属性添加到 YES，但仍然无法点击.

I'm using a method to add a shadow to my buttons. The problem is after that, I can't click in them. I add the userinteractionenabled property to YES, but still can't tap.

这是代码.

我该如何解决?我错过了什么吗?

How can I resolve that? Am I missing something?

- (UIView*)putView:(UIView*)view insideShadowWithColor:(UIColor*)color andRadius:(CGFloat)shadowRadius andOffset:(CGSize)shadowOffset andOpacity:(CGFloat)shadowOpacity
{
    CGRect shadowFrame; // Modify this if needed
    shadowFrame.size.width = 0.f;
    shadowFrame.size.height = 0.f;
    shadowFrame.origin.x = 0.f;
    shadowFrame.origin.y = 0.f;
    UIView * shadow = [[UIView alloc] initWithFrame:shadowFrame];
    shadow.userInteractionEnabled = YES; // Modify this if needed
    shadow.layer.shadowColor = color.CGColor;
    shadow.layer.shadowOffset = shadowOffset;
    shadow.layer.shadowRadius = shadowRadius;
    shadow.layer.masksToBounds = NO;
    shadow.clipsToBounds = NO;
    shadow.layer.shadowOpacity = shadowOpacity;
    [view.superview insertSubview:shadow belowSubview:view];
    [shadow addSubview:view];
    return shadow;
}

推荐答案

我找到了解决方案

在人们的评论之后，我做了一些改变.这是最终的代码

After the comments of the people, I did some changes. This is the final code

+ (void)putView:(UIView*)view insideShadowWithColor:(UIColor*)color andBlur:(CGFloat)shadowRadius andOffset:(CGSize)shadowOffset andOpacity:(CGFloat)shadowOpacity
{
    CGRect shadowFrame = view.frame;
    UIView * shadow = [[UIView alloc] initWithFrame:shadowFrame];
    shadow.backgroundColor = [UIColor redColor];
    shadow.userInteractionEnabled = YES; // Modify this if needed
    shadow.layer.shadowColor = color.CGColor;
    shadow.layer.shadowOffset = shadowOffset;
    shadow.layer.shadowRadius = shadowRadius;
    shadow.layer.cornerRadius = view.layer.cornerRadius;
    shadow.layer.masksToBounds = NO;
    shadow.clipsToBounds = NO;
    shadow.layer.shadowOpacity = shadowOpacity;
    [view.superview insertSubview:shadow belowSubview:view];
}

有了这个，您可以同时拥有圆角和阴影的视图.当然，还启用了触摸事件！

With this, you can have a view with round corners and shadows at the same time. And, of course, the touch events enabled!
