如何使用NSFileManager将UIImage保存到文件？

谢谢,

当我将图像保存到文件时,它以错误的方向保存.

- (void)saveImage:(UIImage *)image:(NSString *)imageName
{
   NSData *imageData = UIImagePNGRepresentation(image);         
   NSFileManager *fileManager = [NSFileManager defaultManager];   
   NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
       NSUserDomainMask, YES);
   NSString *documentsDirectory = [paths objectAtIndex:0];         
   NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:
      [NSString stringWithFormat:@"%@.png", imageName]];
   [fileManager createFileAtPath:fullPath contents:imageData attributes:nil];
}

谢谢.
