I am working on application (using Swift) which has the function to scan barcodes. For this I am using RSBarcodes.
Issue I am dealing with is that I need to scan barcodes from A4 paper sheet which is full of them. However the capturing is too fast and before I can focus on the right barcode the app captures wrong one.
So basically I need to ensure that the device will not capture some barcode, I don't want, but the one I will be pointing on for a longer time. My only idea is to check if the same barcode was captured for example 10 times and based on this assume that this one is the right one. Is there some more elegant solution?
Thanks for any suggestion!
I'm not an iOS dev, so I don't know the specifics - but is there a way you activate the camera but not the scanner? If so, if you can overlay a button in the camera view which says "Scan" - then your user would provide the trigger to capture the barcode once they have settled on a specific one.

I have an app that uses ARKit to detect faces and send over the network the coordinates of interest, which works well. I would like this app to run in background, still sending the data over the network, while I would be using another app (almost) fullscreen.
The option 'Enable multiple windows' is activated in info.plist, but as soon as I launch my other app, the ARKit app stops sending information (the app actually probably stops).
Is there a simple way to do this, and at least is this feasible? Thanks!
This is not possible at this point. Camera and AR stuff is disabled at a system level in apps when they are displayed in Slide Over or Split View.
I'd recommend displaying a warning message when Slide Over/Split Screen is being used saying that you should use the app in full screen mode. See this answer under a different question for details.
I have created application which having the Scan QR functionality, which will scan the QR and once scanning done will show the next screen.
I want to write the UI test case for scanning QR code without opening the Camera.
I have explore and found the launchArguments option, but still not satisfied my requirement.
Is there any way to do this?
Is there an easy way to make in iOS Google Street View GMSPanormaView's camera follow the device's orientation via data from its motion sensors?
If not, has anyone already done it and can share a code snippet that takes data from CoreMotion, maybe manipulates it to create GMSPanoramaCamera, and passes it to the GMSPanoramaView with animateToCamera:animationDuration:?
Any relevant Android code would also be useful.
Upon checking the Maps SDK for iOS:Internal: Street View, there is no built-in function/implementation for the device orientation/ gyroscope sensor.
According to Ziem's answer you can try implement this by yourself(create function). He also give pointers to study the following:
Set the camera orientation point of view
Animate the camera movements

Github
Using a site they have successfully create a function that will let you browse the Google streetview panoramas with your smartphone/tablet like you were inside it, just by moving your phone like a window to the world.
How can I record the operations on iOS, such as touch, move, select, when they happened, the time, the position of action, the action type will be recorded.And then the record can be replay, the actions would be triggered sequencly .
Thank you very much!
I would suggest you this GestureRecognizer:
Add a visual tap effect when you press the screen Record yourself
using the App on the simulator using a screen capture Add in a video
player at the tutorial screen that shows how to use the app
This three action can be done using via AVFoundation framework
or
A another way to this is SIKULI tool. You can automate the demo work flows easily http://www.sikuli.org/download.html
I was wondering if there was a specific method called when we press the 2 buttons of the iPhone (using Home-Button & Power on/off) to take a screenshot. If yes, I would known his name to use her in programming.
There used to be a UIGetScreenImage() function that you could use to capture the screen. Apple no longer allows use of that function in App Store apps, so you have a few other options. CALayer has a -renderInContext: method—Google it—that you can use to copy a view’s contents to a graphics context; this does not, however, work for OpenGL content, video, or live imagery from a device’s camera. I’m not sure about solutions for the first two, but for the latter—getting images from the camera—you’ll need to use the AVFoundation framework.
It is a system level service for which the app never receives any notification or method call.
I believe that would be a native method, not accessible from the IPhone SDK. In what context are you going to be using this? You might be looking for this - Take screenshot from code
