iphone - 如何在 imagepicker 中设置 imagepicker.tag=value

Question

我是 iphone sdk 的新手，当我设置 imagepicker.tag=vaule(100) 时会产生错误，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 的一个属性UIView。UIImagePickerController是 的子类UIViewController。它没有tag属性。
