- [UIViewController awakeFromNib] doesn't call super

Originator:farcaller
Number:rdar://11119157 Date Originated:
Status:Open Resolved:
Product:iPhone SDK Product Version:5.1
Classification:Serious Bug Reproducible:Always
 
Summary:

The UIViewController's -awakeFromNib does not call -[NSObject(UINibLoadingAdditions) awakeFromNib]. Does not allow to tamper into nib loading globally at one place.

Steps to Reproduce:

1. Swizzle NSObject's awakeFromNib.
2. Load a view controller from nib.

Expected Results:

Swizzled method is called.

Actual Results:

Swizzled method is not called.

Regression:

N/A

Notes:

Looking at the possible guessed disassembly

- (void)awakeFromNib
{
    if(_viewControllerFlags & 0x40) {
        BOOL passPredicate = ([self _doesSelfOrAncestorPassPredicate:^{...}] != 0);
        if([self isViewLoaded] && !passPredicate) {
            [self viewDidLoad];
        }
    }
}

it seems that super call is definitely missing out there.
