ios - 如何在 iOS 中保存带有 TextView 数据的图像选择器

Question

我有一个 UITextView，图像选择器并在 View 中提交 UIButton。我想将数据保存在一起，但由于 imagePickerController 使用委托(delegate)方法，因此无论何时在 TextView 中输入数据，它都会被调用。

我是否应该暂时保存来自 didFinishPickingMediaWithInfo 方法的图像，然后在单击提交按钮时检索它？

如果是这样，我该怎么做？

如果没有，如何同时保存textview和image数据？

Answer 1

Should I temporarily save the image from the didFinishPickingMediaWithInfo method and then retrieve it when the submit button is clicked?

是的。

If so, how do I do this?

@property (nonatomic) UIImage *lastSelectedImage;

- (void)imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    self.lastSelectedImage = image;
    [thePicker dismissViewControllerAnimated:YES completion:nil]
}

- (void) buttonPressed:(id)sender {
    // do something with self.myTextView.text and self.lastSelectedImage
}
