QXCameraKit

● https://github.com/akirahrkw/QXCameraKit ● http://cocoadocs.

org/docsets/QXCameraKit/0.1.0/● API library for lens camera● written by swift(80%) and objc(20%)● easy and simple to use:)

QXCameraKitvar manager = QXAPIManager()

// this method does Discovery Request and get Device Description

manager.openConnection({ [unowned self] (result:Bool, error:NSError?) -> () in

if(result) {

// this method gets live image to display on your device

manager.startLiveImage({ [unowned self] (image:UIImage, error:NSError?) -> () in

…

...

self.liveViewImage.image = croppedImage

})

} else {

….

}

})

QXCameraKitfunc didTapLongPressedZoomIn(gesture:UILongPressGestureRecognizer) {

switch(gesture.state) {

case .Began:

manager.api?.startZoomIn({ [unowned self] (json:NSDictionary, isSucceeded:Bool) -> () in

...

}

break

case .Ended:

manager.api?.stopZoomIn({ [unowned self] (json:NSDictionary, isSucceeded:Bool) -> () in

...

}

break

…

}

}

Swift

● currently swift doesn’t have a way to convert a swift function to a C function pointer

● this library uses CFSocketCreate which uses C function pointer. so it needs to use objc
