iOS 将图片保存到本地相册

1、将图片保存到iPhone本地相册

/**
*  将图片保存到iPhone本地相册
*  UIImage *image            图片对象
*  id completionTarget       响应方法对象
*  SEL completionSelector    方法
*  void *contextInfo
*/
UIImageWriteToSavedPhotosAlbum(_image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

2、处理响应结果

//响应对象
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{

NSString * msg = nil;

if (error == nil) {
msg = @"保存成功";
}else{
msg = @"保存失败";
}

}
