FXBlurView是UIView的子类,它实现毛玻璃效果的原理其实就是覆盖上一层FXBlurView的实例对象。

- (void)viewDidLoad {

[super viewDidLoad];

UIImageView * imageView = [[UIImageView alloc] initWithFrame:self.view.bounds];

imageView.image = [UIImage imageNamed:@"Default-Port-hd47"];

[self.view addSubview:imageView];

FXBlurView * aview = [[FXBlurView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];

aview.tintColor = [UIColor whiteColor];  //前景颜色

aview.blurRadius = 20.0;                 //模糊半径

aview.dynamic = YES;                     //动态改变模糊效果

[self.view addSubview:aview];

FXBlurView * bview = [[FXBlurView alloc] initWithFrame:CGRectMake(0, 120, 100, 100)];

bview.tintColor = [UIColor whiteColor];  //前景颜色

bview.blurEnabled = YES;                //是否允许模糊,默认YES

bview.blurRadius = 10.0;               //模糊半径

bview.dynamic = YES;                   //动态改变模糊效果

bview.iterations = 2;                  //迭代次数:

bview.updateInterval = 2.0;            //更新时间(不确定具体功能)

/*

blurRadius = 1.0 && dynamic = 100 的效果和 blurRadius = 10.0 && dynamic = 1的效果大致相同

*/

[self.view addSubview:bview];

FXBlurView * cview = [[FXBlurView alloc] initWithFrame:CGRectMake(150, 0, 200, 200)];

cview.blurRadius = 20.0;

cview.tintColor = [UIColor whiteColor];

[self.view addSubview:cview];

}
