iOS开发 系统自带保存图片到相册的方法

1.代码

- (void)loadImageFinished:(UIImage *)image{    UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), (__bridge void *)self);}- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{    NSLog(@"image = %@, error = %@, contextInfo = %@", image, error, contextInfo);}

2.调用loadImageFinished方法并传入要保存的图片即可
