UIImageView *img1=[[UIImageView alloc] init];
img1.frame=CGRectMake(20, 20, 100, 50);
img1.image=[UIImage imageNamed:@"test1"];
[self.view addSubview:img1];

UIImageView *img2=[[UIImageView alloc] init];
img2.frame=CGRectMake(20, 90, 100, 150);
img2.image=[UIImage imageNamed:@"test2"];
[self.view addSubview:img2];

UIImageView *imageViewMask1 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"test1"]];
imageViewMask1.frame = CGRectMake(0, 0,100, 50);

UIImageView *photoImage1=[[UIImageView alloc] init];
photoImage1.frame=CGRectMake(160, 90, 100, 150);
photoImage1.image=[UIImage imageNamed:@"test2"];
photoImage1.layer.mask = imageViewMask1.layer;
[self.view addSubview:photoImage1];

UIImageView *image3=[[UIImageView alloc] initWithImage:[[UIImage imageNamed:@"wechatback1"] stretchableImageWithLeftCapWidth:10 topCapHeight:25]];
image3.frame=CGRectMake(10, 300, 100, 150);
[self.view addSubview:image3];

UIImageView *imageViewMask = [[UIImageView alloc] initWithImage:[[UIImage imageNamed:@"wechatback1"] stretchableImageWithLeftCapWidth:10 topCapHeight:25]];
imageViewMask.frame = CGRectMake(0, 0, 100, 150);

UIImageView *photoImage=[[UIImageView alloc] init];
photoImage.frame=CGRectMake(170, 300,  100, 150);
photoImage.image=[UIImage imageNamed:@"test2"];
photoImage.layer.mask = imageViewMask.layer;
[self.view addSubview:photoImage];
