清华大佬耗费三个月吐血整理的几百G的资源，免费分享！....>>> 

// 创建UIImage对象
UIImage *image = [UIImage imageNamed:@"sample.png"];

// 创建UIImageView
UIImageView *imageView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ];
imageView.image = image;
[self addSubview:imageView];

// 旋转
CGAffineTransform rotate = CGAffineTransformMakeRotation( 1.0 / 180.0 * 3.14 );
[imageView setTransform:rotate];
