如何在imagepicker中设置imagepicker.tag = value

Question

我是iphone sdk的新手，当我设置图片picker.tag = value（100）然后它会产生错误，所以任何人都可以帮我解决这个问题

   `  imagepicker=[[UIImagePickerController alloc]init];
    imagepicker.delegate=self;
    imagepicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:imagepicker animated:YES];`

Answer 1

imagepicker=[[UIImagePickerController alloc]init];
imagepicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imagepicker animated:YES];
imagepicker.view.tag = 100;

Answer 2

tag是UIView的属性。 UIImagePickerController是UIViewController的子类。它没有tag属性。
