# Sample Application

{% file src="/files/TagauudjcRdk0n0C7CCO" %}

## Build Project

### - Download and Open Project

* Download [**IDCardRecognition-iOS.zip \[147M\]**](https://www.dropbox.com/scl/fi/fb9xeu6l6uetinceabdil/IDCardRecognition-iOS.zip?rlkey=02g8miakb0op9jg1vjajjgjas\&st=uy1od0s9\&dl=0)
* Open the `IDCardRecognition-iOS` project in Xcode.

### - Setting Up SDK License Key

* Add License key:

{% code title="ViewController.swift" lineNumbers="true" %}

```swift
var ret = IDSDK.setActivation("QbxKmXkM8E2X+CzScRgJZlVxWxIlQL5Scimac/QMNoCeCEzEyCbrIdd0rKU09QO5Zz9/NiSGk0xd" +
     "T5TmKuLIAiwiac1GmOcF6yRH8+FeCfLAlX2yoyUI3EuXxgiJ9T+ZQD+y6cW9wOlO5vRxPtPD4H3t" +
     "xTXkgrUzvKvMNI3e+08jfb7WfJ0VTaL3qzcZtQa9btQT1bNl2baUrWlA5W08P8GETFJq4mjHHusQ" +
     "GUGx4a4OF78Rs2S3lbMs9XoeKy+aJEET/rPiubCf7Br1hytmYg9CDi+3mtdewL+6OCzWVntdKL4h" +
     "IRqd+LAWqGgBYbiVzM9lstNiqCuvDE0bJ4Fn0w==")
```

{% endcode %}

* Build Project.

### - Integration Guide

* Activate and Initialize ID SDK

```swift
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    
    var ret = IDSDK.setActivation("QbxKmXkM8E2X+CzScRgJZlVxWxIlQL5Scimac/QMNoCeCEzEyCbrIdd0rKU09QO5Zz9/NiSGk0xd" +
                       "T5TmKuLIAiwiac1GmOcF6yRH8+FeCfLAlX2yoyUI3EuXxgiJ9T+ZQD+y6cW9wOlO5vRxPtPD4H3t" +
                       "xTXkgrUzvKvMNI3e+08jfb7WfJ0VTaL3qzcZtQa9btQT1bNl2baUrWlA5W08P8GETFJq4mjHHusQ" +
                       "GUGx4a4OF78Rs2S3lbMs9XoeKy+aJEET/rPiubCf7Br1hytmYg9CDi+3mtdewL+6OCzWVntdKL4h" +
                       "IRqd+LAWqGgBYbiVzM9lstNiqCuvDE0bJ4Fn0w==")
    print("set activation: ", ret)
    if(ret == SDK_SUCCESS.rawValue) {
        ret = IDSDK.initSDK()
        print("init sdk: ", ret)
    }

}
```

* Extract Data from Camera Frame

```swift
func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
    if(self.cameraRunning == false) {
        return
    }
    
    if(Date().timeIntervalSince1970 - startTime <= 1) {
        return
    }

    guard let pixelBuffer: CVPixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) else { return }
           
    CVPixelBufferLockBaseAddress(pixelBuffer, CVPixelBufferLockFlags.readOnly)
    let image = CIImage(cvPixelBuffer: pixelBuffer).oriented(CGImagePropertyOrientation.right)
    
    let context = CIContext(options: nil)
    guard let cg = context.createCGImage(image, from: image.extent) else {
        CVPixelBufferUnlockBaseAddress(pixelBuffer, CVPixelBufferLockFlags.readOnly)
        return
    }

    let capturedImage = UIImage(cgImage: cg, scale: 1.0, orientation: .upMirrored).fixOrientation()
    CVPixelBufferUnlockBaseAddress(pixelBuffer, CVPixelBufferLockFlags.readOnly)
    
    let result = IDSDK.idcardRecognition(capturedImage) as NSDictionary
```
