Requirements

TGCameraViewController works on iOS 7.0+ version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

  • AssetsLibrary.framework
  • AVFoundation.framework
  • CoreImage.framework
  • Foundation.framework
  • MobileCoreServices.framework
  • UIKit.framework

You will need LLVM 3.0 or later in order to build TGCameraViewController.

Todo

  • Landscape mode support
  • Zoom
  • Image size as global parameter
  • Fast animations
  • Create a custom picker controller
  • Zoom does not work with the camera roll pictures
