PBJVision: An Objective-C repository from chetem

Vision

Vision is an iOS camera engine that supports touch-to-record video, slow motion video (120 fps for supporting hardware, which is currently only iPhone 5S), and photo capture. It is compatible with both iOS 6 and iOS 7 and supports 64-bit. Pause and resume video capture is also possible without having to use a touch gesture as the sample project provides.

I created this component at DIY as a fun means for young people to author video. This same recording interaction was pioneered by Vine and also adopted by Instagram.

Please review the release history for a summary of the latest changes and more information.

CocoaPods is the recommended method of installing PBJVision, just add the following line to your Podfile:
