I have a working application on iOS 4.
I have migrated to SDK 5, and now, on simulator and on devices the application just freeze.
There is no error or crash, just UI totaly freeze.
That occur only on the following case.
I have table view with FetshResultController that have list of object (Managed Objects).
Click on one of the list pushViewController with details.
For each list controller update i call tableView reloadData for the details view.
on iOS 4 there is no problem, but on iOS 5 after some time (can be minute or even few seconds) the entire UI freeze without any error. I need to forcly close the reopen the application.
Why is that issue on iOS 5 ? What can i do ?
(Compiling on iOS 4 is enabled to run on iOS 5, but i try to compile on iOS 5, so i will be able to debug it. iOS 4 SDK cannot "see" iOS 5)

I have an application that uses iOS, todayExtension and watchOS as targets.
Until the launch of the new iOS 13, everything was working fine, that week I downloaded the iOS 13 beta on my iPhone and the watchOS 6 on my watch. Then, suddenly my app loads its objects but when I try to show them on a WKInterfaceTable, it's freezed. The table is there, the number of elements are there, but I can't roll it with drag/crown, I can select a row, but I can't navigate through it.
I already tried moving it out from a group, now the TableView is only below the Interface Controller, so no object should be above the TableView.
Btw,
"Supports Running Without iOS App Installation" checkbox is checked.
After several hours of remaking the bugged screens from mark zero, I found the answer: watchOS 6 is marking the "Fixed to the screen edges" as true by default, and this field made my screens no to scroll anymore!
I hope that no developer spend more hours on this nonsense like I did.
I am developing the iOS watchApp with WatchDevice.
I have facing issues with Running the app in the Real device.
Its keep on showing only ActivityIndicator and nothing goes ahead of this screen.even i tested with Hello world Test App.
By just putting One Static Label,but its still showing same activityIndicator.Anyone knows how to solve this issue??any thing Wrong with My Code or setup?
Recently i have updated my app to support iOS 7.0 but now my app is not working in iPad 1(iOS 5.1.1) and its working fine in iPad 2(iOS 6.1.3) and iPad 3(iOS 7.0).
Right now i am running my app with instruments to improve performance but i am not able to understand that same code not generating memory in iPad 2 & 3 and create problem in iPad 1 only. so whenever i modified code, i need to check in all 3 devices and some of the code is not working in iPad 2(iOS 6.1.3)
I have implemented custom tabbar controller to match iOS 7.0 design in iOS 6 & 5. i am planning to modify to remove custom tababr and implement UITabBarController instead of that.
Let me know is there any easy solution for that or any alternative to solve this problem. do i need to reinstall iOS in iPad 1 or is there any hardware related problem with my iPad 1?
Your problem is that iPad 1 has less memory than iPad2 or iPad3 so memory warning is provoked before. If you want to run your App in iPad 1 you need to improve your memory management. I recommend you that you watch the "Fixing Memory Issue" in https://developer.apple.com/wwdc/videos/.
Good luck!
I have an app released on the app store and I am still working on my iOS 7 update. How will the upgrade to iOS 7 affect the version of my app that is already out there? Will the users who have upgraded still be able to use the existing version?
If your app was built with Xcode 4 and the iOS 6 SDK, it will look the same on iOS 7, except for UIAlertViews and UIActionSheets.
If you make an update to your app with Xcode 5 and the iOS 7 SDK, all UI elements will be updated.
Apple hasn't said how much longer you can submit apps using Xcode 4, but it won't be forever.
If your existing app uses any native controls and ui, it will change in the upgraded iOS. So if you have a navigation bar translucent in your current app, it will show up as the iOS 7 navigation bar translucent. If you have Custom buttons, they will stay unchanged. They will still be there.
So my answer is: Depends.
If you have all the native controls, it will be changed to iOS 7 elements.
If you have all the custom controls (custom buttons, backgrounds etc.), it will not be effected.
Try to look into iOS 7 transition guide once its available.
If you mean how will the existing version of your app work on iOS 7, then, the simple answer is: try it!
Briefing:
Application View Controller Stack:
Navigation Controller > RootViewController > TabbarController
Where RootViewController is a basic UIViewController (like a menu) and lets user to select the starting tab (UIViewController) for the upcoming UITabbarController.
Occurance:
occurs on iPhone 4S, iOS 5
not occurs on iPhone 5, iOS 6
not occurs on any simulator (iOS 5, 6)
After I navigate to UITabbarController (which consists 4 UIViewControllers) if I try to change between tabs, App itself and XCode hangs for an indefinite time (between 5 to 60 seconds). I have disabled all background threads, all network traffic, every singleton. Yet it still hangs while debugging.
This happens once per runtime, only on first change of tabs.
The tricky part is if I disconnect my device from XCode and start app without debugging, there is no such behaviour. I tried to identify where this "hang" occurs. But I was unable to catch the thread/process which is causing it.
Looks like my app chokes during that period and viewDidLoad,viewDidAppear,viewDidDisappear messages starts to flow back in after hang is gone.
How can I address this problem, find out what is causing this?
I am using XCode 4.6.1, iOS base SDK 6.1. I have started this app on XCode 4.3.2, iOS base SDK 5.1. Then upgraded to XCode 4.6.1 and this issue arised.
I also profiled the app for possible leaks, there is no leak and suspiciously app does not hang while profiling.
I am trying to address this issue for days now, it is getting a bit frustrating. I can provide any other details if requested.
