Error loading my managedObjectModel
- by niklassaers
Hi guys,
When I call [myAppDelegate managedObjectModel], in the retain line below, my application will crash (iPhone SDK v3.1.3):
- (NSManagedObjectModel *)managedObjectModel {
if (managedObjectModel != nil) {
return managedObjectModel;
}
managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain];
return managedObjectModel;
}
Here is my crash trace
#0 0x905c44e6 in objc_exception_throw
#1 0x01e78c3b in +[NSException raise:format:arguments:]
#2 0x01e78b9a in +[NSException raise:format:]
#3 0x000af99b in _NSArrayRaiseInsertNilException
#4 0x0001c360 in -[NSCFArray insertObject:atIndex:]
#5 0x0001c274 in -[NSCFArray addObject:]
#6 0x01c16a7e in +[NSManagedObjectModel mergedModelFromBundles:]
#7 0x00002432 in -[myAppDelegate managedObjectModel] at myAppDelegate.m:102
What is going on here? This is template code that I haven't seen fail before.
Cheers
Nik
