iOS 8 模糊视图(毛玻璃效果)的简单实现UIVisualEffectView

标签：ios   ios开发   毛玻璃   

在需要模糊的UIView上，添加一个UIVisualEffectView对象即可。

效果如下图：

代码如下：

    UIImageView *imageview = [[UIImageView alloc] init];

    imageview.frame = CGRectMake(10, 100, 300, 300);

    imageview.image = [UIImage imageNamed:@"2"];

    imageview.contentMode = UIViewContentModeScaleAspectFit;

    imageview.userInteractionEnabled = YES;

    [self.view addSubview:imageview];

    UIBlurEffect *blur = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

    UIVisualEffectView *effectview = [[UIVisualEffectView alloc] initWithEffect:blur];

    effectview.frame = CGRectMake(0, 0, imageview.size.width/2, 300);

    [imageview addSubview:effectview];

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeSystem];

    btn.frame = CGRectMake(10, 50, 100, 40);

    [btn setTitle:@"btn" forState:UIControlStateNormal];

    [effectview.contentView addSubview:btn];
