iOS app to detect 4 QR codes

Job ID: 34955213

Budget: $49 – $50 USD

I need a sample iOS app that turns on the camera and detects 4 QR-codes shown on the screen. User must point the phone at the screen until all 4 QR-codes are detected simultaneously.

Once all 4 are identified, then:
- a snapshot of the image must be taken,
- the exact coordinates of each QR-codes in the snapshot image must be identified,
- as well as the data in the QR-codes must be extracted.

All these pieces must be passed to dummy function Analyze(). It accepts the snapshot image bitmap, the coordinates of the QR-codes (ordered in a left to right, top bottom order), and the data in the QR-codes.

Please note that the snapped image must be in focus. You can either automatically take the image, or ask the user to take it by pressing a button (Which ever is easier.). After the image snapshot is taken, the camera must turn off.
