Installation

Initialization

You initialize an NPCameraView just like any other UIView.
The simplest way is to drag a UIView in IB and change its class to NPCameraView. As soon as an NPCameraView is created you will be able to see a live preview from the camera.

Switch front & rear cameras

// self.cameraView is an instance of NPCameraView

// Switch to the rear camera
self.cameraView.cameraType = NPCameraTypeRear;

// Switch to the front camera
self.cameraView.cameraType = NPCameraTypeFront;

Capture still image

[self.cameraView captureImageWithCallback:^(UIImage *image) {
	// Do something with this new image
    self.myImageView.image = image;
}];

Record video

// Record a 5 second video and save it to a file
NSURL *myVideoFilePathURL = ... // create a full path to a video file (*.mov)
[self.cameraView recordVideoForDuration:5.0f
                              toFileURL:myVideoFilePathURL
                               callback:^(NSURL *videoFileURL) {
                                   if (videoFileURL) {
                                       // Do something with this video
                                   }
                               }];
