Question

I can draw an image into the navbar by adding this to the bottom of my delegate.m class.

@implementation UINavigationBar (UINavigationBarCategory)
- (void)drawRect:(CGRect)rect 
{
UIImage *img  = [UIImage imageNamed: @"nav_bar.png"];
[img drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];   
}
@end

This works great so far, but I would like to have some global BOOL var i can set from all my other viewControllers so I can change the navbar when needs be.

Does anybody know of a good solution? Is there a way to set some global var that all classes can see and that I can reference from with the above method?

Cheers,
-Code

Assuming you have a global bool in your app delegate

@property (nonatomic, assign) BOOL globalBool;

You can access your application delegate from any class in your app like this

id appDelegate = [[UIApplication sharedApplication] delegate];

BOOL gloBalBool = [appDelegate globalBool];

and set the global bool variable

[appDelegate setGlobalBool:YES];
