Change the height of NavigationBar and UIBarButtonItem elements inside it in Cocoa Touch

Question

I suppose it\'s not strictly in line with Apple guidelines but I guess it must be possible somehow. I\'d like to change the height of navigation bar inside UINavigationContr

Answer 1

I managed to do something similar by subclassing UINavigationBar and overriding -layoutSubviews. The code looks like:

-(void)layoutSubviews {
    [super layoutSubviews];
    int i = 0;
    for (UIView *view in self.subviews) {
        NSLog(@"%i. %@", i++, [view description]);
        if ([view isKindOfClass:NSClassFromString(@"UINavigationButton")]) {
            view.frame = CGRectMake(0, 0, 100, 50);
        }
    }
}

If you need to know how to subclass UINavigationBar, have a look at this very good answer.

I am not really sure about the NSClassFromString(@"UINavigationButton")] part. It works, but I did this as an experiment, and I'm not sure if this will get approved by Apple. I hope someone with a better knowledge might shed some light.
