2. Launching the app.

Improve support for Macro PDF Once you finish the editing, deploy the app and run it on a real device again. Tapping the scan button should bring up the built-in camera and start capturing video. However, at this point the message label and the top bar are hidden. You can fix it by adding the following line of code.

This will move the message label and top bar to appear on top of the video layer. Re-run the app after making the changes. The message label No QR code is detected should now appear on the screen. As of now, the app looks pretty much like a video capture app. How can it scan QR codes and translate the code into something meaningful? The app itself is already capable of detecting QR codes. Here is how we are going to tweak the app:. Add the following code in the do block of the viewDidLoad method:.

Later, when a QR code is detected, we will change its size and turn it into a green box. In order to capture the QR code and decode the information, we need to implement the method to perform additional processing on metadata objects. Here is the code:. The second parameter i.

These couple lines of code are used to set up the green box for highlighting the QR code. By calling the transformedMetadataObject for: From that, we can find the bounds of the QR code for constructing the green box.

Lastly, we decode the QR code into human-readable information. This step should be fairly simple. Once launched, tap the scan button and then point the device to the QR code in figure The app immediately detects the code and decodes the information. The demo app is currently capable of scanning a QR code.

Your task is to tweak the existing Xcode project and enable the demo to scan other types of barcodes. Atlease post the code how to remove the red horizontal line on top of Scanner view. Thank you sir! Thanks so much, but i have a trouble , the scan time its so slow, do you have any solutions?
