Nib from different class

Question

I have tried several other examples, on this site and others, but for the life of me I cannot get this to work.

I have a NIB file which is a part of the class "ViewController2". I need to use a few of the views in this NIB file in my "ViewController1" class.

Each time I call

[[NSBundle mainBundle]loadNibNamed:@"ViewController2" owner:self options:nil];

it causes a crash, saying that one of my UIButtons is not KVC compliant, but I have properly linked all the buttons and outlets, to no avail.

Any help would be extremely appreciated! Thank you in advance!

Will the suggestion on the accepted answer of this question work for you? http://stackoverflow.com/questions/5849330/one-xib-file-with-multiple-files-owners — trojanfoe, Aug 25 '13 at 07:49
I tried that trojanfoe, but after entering the following code: VC2 *VC2 = [[VC2 alloc]init]; [self addChildViewController:VC2]; [_containerView addSubview:advancedMenu.stopwatchView]; I get the following error: *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key customAboutBtn.' — Will, Aug 26 '13 at 11:03

that is faster at least 3 times than NSBundle:

ViewController2 *_viewController2 = [[[UINib nibWithNibName:@"ViewController2" bundle:nil] instantiateWithOwner:nil options:nil] objectAtIndex:0];

it will load the nib file and it will create a new instance of the ViewController2 class.

NB: if you'd like to use an already existing instance of the ViewController2 class for the nib, you will need to set that instance as owner.

When you load a nib and set the owner: property to self, iOS tries to wire up the outlets with KVC. If you don't have a UIButton with a keyPath that matches the one in the xib file inside of the class you're currently in, you'll get the crash. You need to set owner: to nil.
