Crash on creating new persistence store (jailbroken iPhone device 4.1)

Question

Hi there,

Whenever I deploy "CoreDataBooks" Apple iOS sample application to my jailbroken device with self signed certificate and run it - it crashes at line where core-data persistent store is added to persistent store coordinator:

line 178:

if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) {

// Update to handle the error appropriately. NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); }

It is also interesting that application's "Document" directory was never created and sqlite was never copied into it, so I'm suspected that it might be connected to write permissions issue. However, I've tested app by setting 777 permissions recursively and it was the same.

Sample works fine with iPhone Simulator.

Environment summary:

• Xcode 3.2.4 / iOS SDK 4.1
• Device: iPhone4 (iPhone3,1)
• Firmware: 4.1 (8B117)
• Jailbroken with: PwnageTool 4.1.2

Self signed certificate for code signing was used as described at http://ihackmyi.com/forum/index.php/topic,24020.0.html

Complete code was downloaded from this location: http: //developer.apple.com/library/ios/#samplecode/CoreDataBooks/Introduction/Intro.html

For building purpose, sample configuration was slightly changed:

1. Base SDK: iOS Device 4.1
2. Code Signing/Any iPhone OS Device: "Xcode Code Sign"
3. iOS Deployment Target: iOS 4.1

I used SSH to deploy it to /Applications directory on the device and set permissions to 777 with:

iPhone:~ root# chmod -R 777 /Applications/CoreDataBooks.app

I used Respring to restart Springboard and after that I run CoreDataBooks app and it crashed with following crash log (I provided symbilized version):

It is the same with other core-data related samples.

Thanks in advance, Nikola

Answer 1

Just a guess, but try to create the documents directory manually. It crashes because of the abort(); which gets called when the persistent store could not be accessed. And it can't be accessed (i.e. created) if the directory is not there.

I think the documents directory is created upon regular install of the app.

Or try adding this somewhere at the beginning:

NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
[[NSFileManager defaultManager] createDirectoryAtPath:path attributes:0];
