armv7 0x000025a8 start (in MyApp) + 32

But i am not sure what it describes , please let me know that what it explains

Thanks a lot for your help.

Answer 1

SIGABRT is the most generic type of crash. If you are running say an iPhone 3gs and your client is using a newer iPhone 4/4s for example you could be compiling for different architectures (Armv6/7) make sure its set to Armv6 in that case and it also looks like one of the methods you are using may be deprecated. Look for code in main.m. There are a lot of instances where you have to use iOS version difference code (but most of it is for iOS4/iOS5)

Answer 2

I had the same problem, I was using core data in my app, so if you are using core data, maybe this answer will help you, I fixed mine by changing the persistentStoreCoordinator store code.

    ....
    - (NSPersistentStoreCoordinator *)persistentStoreCoordinator {

        if (persistentStoreCoordinator != nil) {
            return persistentStoreCoordinator;
        }

        NSURL *storeUrl = [NSURL fileURLWithPath:[[self applicationDocumentsDirectory] stringByAppendingFormat:@"yourdb.sqlite"]] ;
    ....

Check this line

NSURL *storeUrl = [NSURL fileURLWithPath:[[self applicationDocumentsDirectory] stringByAppendingFormat:@"yourdb.sqlite"]] ;

Changed the above line to

NSURL *storeUrl = [NSURL fileURLWithPath:[[self applicationDocumentsDirectory] stringByAppendingPathComponent:@"yourdb.sqlite"]] ;

This just solved my problem.
