iOS8 模糊视图(毛玻璃效果) UIVisualEffectView

在需要模糊的UIView上，，添加一个UIVisualEffectView对象即可,若直接在storyboad里面直接加UIVisualEffectView，你的项目必须是iOS8以上才能用

– (void)viewDidLoad {

[superviewDidLoad];

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

//

// imageview.frame = CGRectMake(10, 200, 300, 300);

//

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

//

// imageview.contentMode = UIViewContentModeScaleAspectFit;

//

// imageview.userInteractionEnabled = YES;

//

// [self.view addSubview:imageview];

effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *effectview = [[UIVisualEffectView

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

effectview.frame =,view.frame.size.width,self.view.frame.size.height);

//[imageview addSubview:effectview];

[self.viewaddSubview:effectview];

buttonWithType:UIButtonTypeSystem];

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

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

[effectview.contentViewaddSubview:btn];

}

让我们将事前的忧虑，换为事前的思考和计划吧!
