Question

In iOS development when using Core Data framework, why this line wont work in real device:

NSURL *storeUrl = [NSURL fileURLWithPath: 
                  [[self applicationDocumentsDirectory] 
                       stringByAppendingPathComponent: @”MyDB.sqlite”]];

Doesn’t this mean that the DB file is under UUID/Documents directory? or it means it is under UUDI/MyApp.app/Documents?

Answer 1

applicationDocumentsDirectory should be pointing to GUID/YourApp/Documents

This would be a correct usage to get the Documents directory

+(NSString *)applicationDocumentsDirectory {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
    return basePath;
}

What is the applicationDocumentsDirectory code? Assuming you are using it from an example, either from Apple or another reliable source, this should point to your apps Documents folder.
