I am facing a unique problem. I have this app uploaded on app store. I am using MPMoviePlayerController in the app. Many people have complained that they are getting no sounds in the videos.
When I asked them what is the os version - all of them have iOS 5.0. Now I also updated my iPad to iOs 5 and tested the app. I am getting no problem. Everything is working fine.
What can be the problem? How do I resolve this issue because I am unable to recreate this error in my iPad?
Please help.
Thanks

I have an app that shouldn't rotate unless on one particular screen.
The problem is that it is rotating on all screens, but the real big problem is that it only occurs when the users download the app from app store and are using it on iPhone 5, so I can't really find a way to test and fix the bug, since I wasn't able to reproduce it (in a development environment) so far.
I believe this is not an iOS problem since other devices with the same version are doing ok with the version I uploaded to apple through XCode, the bug really only occur when downloaded from app store and is installed on iPhone 5.
Any thoughts on what might be happening or how to fix it?
Thanks in advance!
I'm recording audio on every iOS simulator available and on some devices without any problems (for example iPhone 4 with iOS 5.1.1 or iPhone 4S with iOS 6.0.1), but recently I got feedback from my client telling me that audio recording on iPhone 4 with iOS 6.0.1 fails with no crash - they click record and nothing happens. Has anyone encountered that problem? Is this device specific? Or the usually working and widely used code for AVAudioRecorder needs to have some specific settings on this one device + system combination?
Happened to me too and in my case PrepareToRecord() was failing because a folder in file's path was missing (not created yet).
i don't have a jailbraked iPhone and i don't want to jailbrake it for now. I convert my myAppName.app application to myAppName.ipa. I load my app on iTunes but when i sync, the app is not installed on my iPhone. My iPhone iOS is iOS 6, i make apps on Xcode 4.4.1 so on iOS 5.1, so i can't run my app on my iPhone from Xcode.
Can someone tell me how can i solve this problem?
(Sorry for my English)
If I understand you correctly, you are trying to run your app on iPhone. Correct? If that's the case, you will have to purchase a membership on develop.apple.com. Once you have done that follow the steps on: http://www.youtube.com/watch?v=dUdHifLTyrE&feature=BFa&list=PLdtvnlkHu09KgpdUgjkUnoTWqwTcqKGGH . I recommend following this video because the steps have been explained very clearly and if you follow it carefully, chances are you will be able to run your app in the first shot.
Also, if you using Xcode 4.5 to develop apps and running them on 3.5" screen, please uncheck "Use Autolayout" under File Inspector. For more info, please check: presentViewController: crash on iOS <6 (AutoLayout)
Hope this answers your question! All the best!
I released an iPhone/iPad app some weeks ago. From 15 reviews (worldwide) I got a dozen 1 star reviews from users saying the app does not work, they only get a blank screen. The other three are happy and it works for them.
I tested the app on an iPad 1, an iPad 2, an iPhone 3GS and several iPhone 4s - it worked on every device flawlessly. And it passed the app store submission process, so it must have worked at Apple...
The crash report in iTunes Connect is empty - the app obviously does not crash, it just hangs somewhere.
Unfortunately there is no way to contact the users where it doesn't work :-(
I know its really hard to help with that less information, but I don't know what to do when I can't replicate the problem on my side...
So does anybody has any idea?
If its a memory problem - shouldn't the app crash then?
I use AVFoundation to play a movie and I know of some flaws since its a relatively new library - does somebody know of this problem (a blank screen) in relation with AVFoundation?
It would be helpful as well if you could download the app (the name is "Hyperactive") and test if you get a blank screen. If so I would be glad to learn the exact device and the iOS version. I hope this is not missunderstood as spam, thats not what I intend...
Thanks in advance,
best regards,

This is a longshot, but maybe the user had the application running for a long time, receiving a viewDidUnload, and something you unload is not getting reloaded on the viewDidLoad.
Try running a "Simulate Memory Warning" on the iphone simulator options.
Both iPhone and iPad versions work fine on iPad 1.
Application won't install on iPhone 3G with iOS 4.2.1.
Have you tested your application on a jailbroken device?
It turned out that the black screen only happens on an iPod Touch and the solution is very easy:
You need an additional entry in the .plist file for the iPod Touch:
Main nib file base name ...
iPod Touch 4G thinks it's an iPad
I have an app that uses AVAudioPlayer to play some embedded MP3 files. The volume buttons work reliably on the 3GS I mostly use for testing -- they worked under 4.1 and work now after upgrading to 4.3.1. On my boss's iPhone 4 running 4.2.1, they don't seem to work in our app at at all; and on the iPod Touch (also running 4.2.1) that's my secondary test machine, I've been able to get them to work once but can't reproduce how I did it.
I tried a hack I found, creating a dummy AVAudioPlayer at application startup but leaving it in prepareToPlay state, and found I was able to use the volume buttons on my initial screen, but once I was playing real audio they stopped working.
Anyone run into this? Any ideas why it works on some phones and not others?
Update: I updated the Touch to 4.3.1 and the problem went away. I assume therefore it's probably a bug in 4.2.1, but I'd still like to know if anyone's seen it and/or can point me to a bug report.
I had same problem. I found that the YouTube App was setting the default volume on the AVAudioPlayer. Found this with iPhone 4.3.3 so I am not sure if you are out of the woods yet.
