UIImagePickerController exception : "Source type must be UIImagePickerControllerSourceTypeCamera"

Question

what is wrong with this? I really don't understand some important parts for UIImagePickerController....

here's the source:

     UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;        
imagePickerController.delegate = self;
[self presentModalViewController:imagePickerController animated:YES];
[imagePickerController release];

Can't I open the photo library? Any help appreciated!

Answer 1

If you're using the photo library, do you need to set cameraCaptureMode?

Answer 2

Maybe not in your case but when you initalize your UIImagePickerController object, FIRST you need to set your source type before setting any other properties otherwise you get the same error.

let imagePickerController =  UIImagePickerController()
imagePickerController.sourceType = UIImagePickerControllerSourceType.Camera
imagePickerController.cameraCaptureMode =   
UIImagePickerControllerCameraCaptureMode.Photo
imagePickerController.cameraDevice = .Front
imagePickerController.showsCameraControls = true;
imagePickerController.navigationBarHidden = false;
imagePickerController.toolbarHidden = false;
imagePickerController.delegate = self
