ios - 在 iphone 模拟器上使用 UIImagePickerController

Question

我有方法，从画廊或相机拍照

-(IBAction) getPhoto:(id) sender {
  UIImagePickerController * picker = [[UIImagePickerController alloc] init];
  picker.delegate = self;

  if((UIButton *) sender == choosePhotoBtn) {
        picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
  } else {
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
  }

  [self presentModalViewController:picker animated:YES];
}

但是当我在模拟器上运行它时，代码不起作用。它在 picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum 和 picker.sourceType = UIImagePickerControllerSourceTypeCamera

中不起作用

是模拟器的问题还是代码的问题？

Answer 1

试试这个，

 if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
        {
            picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        }
        else
        {
            picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
        }
        [self.navigationController presentModalViewController:picker animated:NO];

如果您正在为 iPad 创建应用程序。您必须在 popOver 控件中显示图库。
