1、保存到iOS照片库需要引入QuartzCore.framework框架，具体代码如下：
.h文件
#import <QuartzCore/QuartzCore.h> UIImageView *imageView; @property (nonatomic, retain) IBOutlet UIImageView *imageView; .m文件 UIGraphicsBeginImageContext(imageView.bounds.size); [imageView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *temp = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIImageWriteToSavedPhotosAlbum(temp, nil, nil, nil);
2、保存到对应的沙盒目录中，具体代码如下：
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES); NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"sms.gif"]]; // 保存文件的名称 BOOL result = [UIImagePNGRepresentation(imageView.image)writeToFile: filePath atomically:YES]; // 保存成功会返回YES
