iOS开发之如何实现毛玻璃效果
我们在开发中有时候项目需要可能会需要实现毛玻璃效果,诸如下图,它并不是仅仅设置一下透明度就能搞定的,从图中可以看出这个view并不是透明,而是有点模糊效果。

上代码:

附:方便粘贴
//创建背景view
UIView *alpView = [[UIView alloc]initWithFrame:CGRectMake(10, 0, SCREEN_Width - 20,frame.size.height - 10 )];
alpView.frame = CGRectMake(0, 0, SCREEN_Width - 20,frame.size.height - 10 );
alpView.backgroundColor = [UIColor blackColor];//根据需要设置,可不写
alpView.alpha = 0.1;//根据需要设置,可不写
alpView.layer.cornerRadius = 5;
alpView.layer.masksToBounds = YES;
//创建毛玻璃
UIBlurEffect * blur = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView * effe = [[UIVisualEffectView alloc]initWithEffect:blur];
effe.frame = CGRectMake(10, 0, SCREEN_Width - 20,frame.size.height - 10);
effe.layer.masksToBounds = YES;
effe.layer.cornerRadius = 5;
effe.alpha = 0.9;
//把要添加的视图加到毛玻璃上
[effe addSubview:alpView];
[self addSubview:effe];
