在iPhone模拟器上使用UIImagePickerController [英] Use the UIImagePickerController on a iphone simulator

问题描述

我有方法，从画廊或从相机拍照

I have the method, that take photos from gallery or from the camera

-(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，代码不工作。它不能在 picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum 和 picker.sourceType = UIImagePickerControllerSourceTypeCamera

But when i run it on the simulator, code doesnt work. And it doesnt work in picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum and picker.sourceType = UIImagePickerControllerSourceTypeCamera

是模拟器或代码中的问题吗？

Is the problem in the simulator or in the code?

推荐答案

Try this,

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

如果您正在创建iPad应用程序。您必须在popOver控件中显示图库。

If you are creating the app for iPad. You will have to present the gallery in a popOver control.
