Taking photo and video on iOS device - ios

Question

Im trying to be able to take and capture a photo and show it in a uiimage view AND/OR take a capture a video and play it back in a movieplayercontroller.
I am able to click a button and "Take Photo" which does display in my uiimageview just fine. However the image disappears out of the uiimageview if i click a button to "Take Video" The take video works and displays back fine but like a said my uiimage has now disappeared.
If i go back to re take the photo the video i captured disappears?

I haven't actually compiled and run your code, but looking at it, you're defining imagePicker in the class instance, whereas you're defining picker inside the TakePhoto method. My guess is that when you run through the process, the method instance is being destroyed once it completes.
Instead, try using a single imagePicker instance declared at the class level, set its properties differently depending on whether the user is loading an image or video, and set the selected media accordingly.
