教你几行代码实现图片的模糊效果

1     // 创建图片
2     UIImageView *imgView = [[UIImageView alloc]initWithFrame:[UIScreen mainScreen].bounds];
3     imgView.image = [UIImage imageNamed:@"1"];
4     [self.view addSubview:imgView];
5     //添加模糊效果
6     UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
7     UIVisualEffectView *effectView = [[UIVisualEffectView alloc]initWithEffect:blurEffect];
8     effectView.frame = [UIScreen mainScreen].bounds;
9     [imgView addSubview:effectView];
