有的時(shí)候需要添加一個(gè)高斯模糊效果,或者毛玻璃效果,但是高斯模糊是針對(duì)圖片的,處理圖片的像素.UIView應(yīng)該怎么做呢?
上代碼:
UIBlurEffect *blur = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
UIVisualEffectView *effectview = [[UIVisualEffectView alloc] initWithEffect:blur];
effectview.frame =self.view.frame;
[self.view addSubview:effectview];
