在我的相机应用程序中，当我单击图像时，它会向用户询问标题和描述，然后保存它。现在它正在保存图像，但不询问标题和描述。我是 iOS 的新手。所以，可能是这样是一个愚蠢的问题。请帮助我得到这个。对于相机点击我正在使用这种方法：-

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

BOOL camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
if(camera)
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    [[picker navigationBar]setBarStyle:UIBarStyleDefault];
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    [picker setDelegate:self];
    [self presentViewController:picker animated:YES completion:NULL];

    [picker release];
}

您可以通过以下方式执行此操作：

  • 使用相机单击图像。
  • 在不保存图像的情况下返回您的应用程序。到目前为止，您将获得在您的应用程序中单击的图像的引用。
  • 向用户询问标题和描述。

  • 使用这行代码将图像保存到图片库：

    UIImageWriteToSavedPhotosAlbum(UIImage *image, id completionTarget, SEL completionSelector, void contextInfo);

希望它可以帮助你。
