ios app strange crash on start

Question

My project, called OBI, works fine when launched from Xcode, but when I create .ipa file its crashes with provided log. In project no classes with names: Mutex, DelayedPointerDeletionManager or MemoryManager, so I can't understood from where this exception.

I will be very pleased for any help, or direction to dig

EDIT Finally I found what causes this exception. Is symbol striping option in build setting, after I changed it from all symbols to debug symbols everything become fine.

Answer 1

This is crashing in the dynamic loader as iOS loads your classes into memory. Part of this process is calling +load on any classes that implement the method.

One possibility is that you are doing too much work in +load, and are being killed with a "Failed to launch in time". Providing the full crash log would show whether this is the case.

Answer 2

From what I can see (it would help if you show some code, especially your applicationDidFinishLaunching method) it looks like your app is taking too long to launch and is being killed by the OS.

An app has a certain time limit to set up a root view controller and do any basic set up. if it takes too long, the OS considers it non responsive and kills it. You won't notice this problem when launching from Xcode because the time limit is disabled when launching with a debugger attached: see here https://developer.apple.com/library/ios/qa/qa1592/_index.html

If you are downloading an image in your app delegate I would suggest switching to an asynchronous approach, and also probably handling the image loading from the view controller which will use the image

edit: it looks like you get a different error from the console than the Q&A describes, but without any code I can't help much more than that

Answer 3

ImageLoader is linked to the loading of code pieces (external framework, libraries). You should make sure you all those are "see-able" by your binary. Building in XCode can put all in the same folder so you have no path issue but, an din particularly if you are referencing third parties framework you need to make sure they can be "seen" by the main executable. Does the console spit anything?
