简书开篇写一个简单的例子纪念一下！
最近有一个项目，要显示该用户是否认证过
head认证.png
这其实是两个view，底部一个头像view，上面覆盖一个认证信息view。
UIImageView *headV = [[UIImageView alloc]initWithFrame:CGRectMake(100, 100, 120, 120)];
headV.image = [UIImage imageNamed:@"systemM"];
headV.clipsToBounds = YES;
[self.view addSubview:headV];
UIImageView *imageV = [[UIImageView alloc]initWithFrame:CGRectMake(-25,5, 85, 30)];
imageV.image = [UIImage imageNamed:@"ided"];
CGAffineTransform transform= CGAffineTransformMakeRotation(-M_PI*0.25);
imageV.transform = transform;
[headV addSubview:imageV];```
直接上代码。
