ViewDidAppear with UIImagePickerController.

Is there a way to do a ViewDidAppear with UIImagePickerController when switching to another view? all I get is the camera reloading after I press the "use" button. Help would be much appreciated! Thank you.

Not sure what you mean, you want viewWillAppear to get called when a presented UIImagePikerController has a button pressed?

If I understand correctly, tapping Use causes the UIImagePickerController to disappear, but then it appears again because you are presenting it in viewWillAppear? If you proceed with the course, you will find that we wrap the call to present the UIImagePickerController in an if statement that prevents it from showing again:

if (self.image == nil && [self.videoFilePath length] == 0) {

Have you implemented any code in imagePickerController:didFinishPickingMediaWithInfo:? That gets called when you tap Use. You can set a property or something in that method that you can check in the viewWillAppear or viewDidAppear methods.

Hope this helps!
