保存图片到相册

//接口中定义这个方法,然后在实现类中实现他
- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *) contextInfo;

//实现类中实现
- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *) contextInfo {
    NSString *message;
    NSString *title;
    if (!error) {
        title = @"成功提示";
        message = @"成功保存到相";
    } else {
        title = @"失败提示";
        message = [error description];
    }
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                    message:message
                                                   delegate:nil
                                          cancelButtonTitle:@"知道了"
                                          otherButtonTitles:nil];
    [alert show];
    [alert release];
}

//调用方法保存到相册的代码
 UIImageWriteToSavedPhotosAlbum(img, self, @selector(imageSavedToPhotosAlbum: didFinishSavingWithError: contextInfo:), nil);
