this class is not key value coding-compliant for the key givenName [duplicate]

Question

SO i have this

- (void)loadView { BOOL success; NSFileManager *fileManager = [NSFileManager defaultManager]; NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString* databasePath = [documentsPath stringByAppendingPathComponent:@"ProxDeals.db"]; NSError *error;  BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:databasePath]; if (fileExists==TRUE) {     [[NSBundle mainBundle] loadNibNamed:@"ProxDealsViewController" owner:self options:nil]; } else {     NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"ProxDeals.db"];     NSLog(@"%@",defaultDBPath);     success = [fileManager copyItemAtPath:defaultDBPath toPath:databasePath error:&error];     if (!success) {         NSAssert1(0, @"Failed to create writable database file with message '%@/.", [error localizedDescription]);     }     [[NSBundle mainBundle] loadNibNamed:@"UserRegistration" owner:self options:nil]; } 

}

and this error:

 Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<ProxDealsViewController 0x5f22160> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key givenName.' 

I know that i don't do something wright in the initialization of the UserRegistration nib but i don't know how to fix this.

This usually means that something is trying to access the @property "givenName".

If you were doing something with IB, the usual cause is that you either:

• deleted that property from the class, but haven't deleted the hookups in IB yet
• OR: you have a File's Owner object set to the wrong class (check the properties - different depending which version of xcode you're using - to find the Class Name its set as. You probably copy/pasted a NIB file, and didn't change this field in the NIB), and you've hooked up an outlet for that class, but your actual File's Owner is something different
