You have two options for doing what you want, either stick with and customize a UIImagePickerController, or create your own by using the AVFoundation.

The UIImagePickerController does provide a fair bit of customization options, and this similar thread has some good information on that: link.

If you still want to make your own, I suggest heading over to the Apple Documentation and checking out this demo project called AVCam: link. However, it's way more in-depth than you'll probably need so I can recommend this video tutorial as well: link.

If going for the last option, I would like to mention that to make the "actual camera" fit the frame of your previewLayer, you can set the videoGravity on the AVCaptureVideoPreviewLayer to AVLayerVideoGravityResizeAspectFill.

Working with a custom camera can be a bit of a pain, but it’ll pay dividends given that you’ll really be able to customize your app experience.

The easiest way to do it is to use TGCameraViewController.

Using this TGCameraViewController, you can edit whole camera view. Also, It provides following functionalities:-

• Easy way to access album (camera roll)
• Flash auto, off and on
• Focus
• Front and back camera

Also you can refer AVCamManual: Extending AVCam to Use Manual Capture document for creating own custom camera.
