iOS8毛玻璃效果-UIView模糊效果_uiblureffectstyledark

最近公司忙，没来得及写博客，补发一篇UIView模糊处理的小技巧，希望大家能用得上

//定义毛玻璃效果

UIBlurEffect * blur = [UIBlurEffecteffectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView * effe = [[UIVisualEffectViewalloc]initWithEffect:blur];
effe.frame =CGRectMake(50,90, self.view.frame.size.width - 100, 400);

// 把要添加的视图加到毛玻璃上

UIButton * btn = [[UIButtonalloc]initWithFrame:CGRectMake(50,50, 100,100)];
btn.backgroundColor = [UIColorredColor];
[effeaddSubview:btn];
[self.viewaddSubview:effe];

效果是枚举，有三种：

UIBlurEffectStyleExtraLight      UIBlurEffectStyleLight      UIBlurEffectStyleDark

之后还有你想把你的图片模糊也可以这样添加：

// 定义需要毛玻璃化的图片

UIImageView * image = [[UIImageViewalloc]initWithImage:[UIImageimageNamed:@"2.png"]];
image.frame =CGRectMake(100,100, 100,100);

// 定义毛玻璃效果

UIBlurEffect * blur = [UIBlurEffecteffectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView * effe = [[UIVisualEffectViewalloc]initWithEffect:blur];
effe.frame =CGRectMake(50,90, self.view.frame.size.width - 100, 400);
[image addSubview:effe];
[self.viewaddSubview:image];
