I made an Ecommerce app for iPhone and iPad using objective c. The app is working fine on iPhone but crashing a lot on iPad. I am getting lot of memory warning on iPad. I tried different things to get it control but not getting any success. Apps has features like
As per user current location it shows the store on map view and list view.
During checking user can order as per his current location or can place an order for different location.
Add favorite product and favorite store
Can anyone suggest what I might be doing wrong or anything I should implement to get it fixed.
Use Instruments. That's actually the only device that anyone can give you. And of course be aware that if your app is in the background, crashing after a memory warning is quite normal and not something the user will even notice.

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.
Does anyone know when the App Store started requiring the app previews to be on a physical device and show this pop-up?
Even when I mirror my iPhone Xs to my Mac, the pop-up does not show. If no pop-up on video, app store rejects app preview.
Anyone know of a better way to get around this issue?
Another image that shows issue:
This pop-up NEVER shows on screen recording or mirroring....
We have same problem. You have two options:
You can record the screen from another mobile or camera
You can use a previous iOS. We have checked that permission dialog can be screen recorded with iOS12
What was your solution?
Yes, has been steadily, over the past 3'ish years or so, working on removing certain system sensitive controls from being displayed in that feed. My guess it's for $SEKURITY reasons, though it doesn't completely make sense, to me, what would be the attack vector that it attempts to prevent.
The location dialog is not the only case I know that it hides. It originally started with them hiding even *** in the password text fields, and hiding the keyboard in such input, as well. Apparently it now expanded to location, and likely other system dialogs. 🤷♂️
Surprisingly few people seem to be discussing this.
I published an app last year (2021 / June) on 14.? which required the popup and it was accepted. Did this again with another app just after 15.? and I cannot get it past the apple store. Once they allowed me to post a video recording and I got it through, but since then ... no chance.
How are people getting their app through - I assume apple use the screen capture system to do their testing.
I had the same problem but my app was accepted.
Surely screen recording does not work, but screen capture does. I have embedded a screenshot of the permission dialog into a video and submitted it for app review.
I am writing a piece of code using swift for iOS.
It’s using location services. I need to take a screenshot of the current screen every time the location gets updated.
The thing is when the app is running in background and updating the location the screenshots taken are from my app. Not the app which is currently available in the screen.
Assume that the user plays a game in their phone. But my app run in background and updating the location when the users location is significantly changed the screenshot should be taken and it should include the game. Not my app screen.
Can some one tell me how to achieve the screenshot capability I want.
Short answer: You can't.
Apps can only take screenshots of their own content. Starting with (I think) iOS 7 Apple blocked the ability of apps to take screenshots of anything but their own content. This is for security reasons.
Imagine your app echoes each character of your password as you type it, and then replaces it with a bullet as you type the next character. Now imagine an app that runs in the background and takes a screen-shot every time your app displays a new character of the user's password.
I have a app that opens straight to a camera that is based on this WWDC sample: https://developer.apple.com/library/ios/samplecode/AVCam/Introduction/Intro.html
A few users have been experiencing a bug where the camera does not turn on and does not allow them to capture content.
I just ran into the same issue last night and this is what I observed:
I was debugging a separate issue and the camera was working 100% ok, then all of a sudden, it stopped working.
Every time I would open the app or navigate back to the camera, it would show a dark view of whatever it was currently pointing at, but the image was frozen. Its like it worked for 1 second, then the capture preview would freeze.
I tried force closing and reopening, same problem.
I tried uninstalling and reinstalling, same problem.
I then restarted my phone and the issue was solved.
How is it possible that this bug persists between separate installs?
Does anyone know what might be causing the camera to fail?
How should I go about debugging it if it only occurred once after months of using it and I have no idea what triggers it?
Are you running iOS 9?
That might be an iOS 9 software internal bug.
I had exactly the same non-reproducible issues but with MapKit's map view rendering.
In my case map view was showing just rectangle grid without any map objects - no streets, lakes, rivers, etc.
I've tried to google over internet to find potential reason of such weird issue, but without any luck. Then I've restarted device and that helped, the same as in your case.
Sure, my info is not a full answer, just want to share my experience.
Your process does not have direct access to the camera hardware, but rather through a device manager. It is the state of that manager that determines if things will work.
To confirm, when your app is experiencing issues, kill it then open the default Camera app. If it shows a blank or still frame preview, then you know it's not necessarily a problem in your app.
I have developed an iOS enterprise app for iPad. When it is launched it connects to a webservice, gets some data, and stores it in Core Data. Then the next screens use this data and do what is needed, like fill UITextFields, drop downs, show the user a UIAlertView, etc. Basically i use the data, manipulate it, and save it.
Consider this: I install the app now in morning, I use it immediately, and then I click the home button on iPad and leave it there for couple of hours. I then launch the app, and it shows a black screen before crashing and going back to iPad main menu.
Why is it crashing like that? Any ideas?
If you need more information please let me know.
You need to check your logs for errors.
Plug your device to your computer and open Xcode/Organizer/Devices/Device Logs
