TTNavigator and TTStyleSheet

[CG]

Hi,

I'm setting a global style sheet to change the navigationBarTintColor
in my app delegate like this:

[TTStyleSheet setGlobalStyleSheet:[[[DefaultStyleSheet alloc]
init] autorelease]];

That is working just fine, except when when my app state is restored
by calling restoreViewControllers in TTNavigator. In that case, the
navigation bar is showing the iOS default, pale blue color. When I
navigate on to the next view, the style sheet takes effect again.

I would really appreciate any hints on this...

Best regards,
Christian

Have you tried putting something in

- (void)applicationDidBecomeActive:(UIApplication *)application;

?

I'd be tempted to try setting the navbar color directly from there.

The other thing I notice is that my views tend to have this:

- (void)viewDidAppear:(BOOL)animated
{
   self.navigationController.navigationBar.tintColor
}

which works, but is obviously less than ideal.

Rob.

The approach Robert states in viewDidAppear is the way I do it but in viewWillAppear instead

Robert, ep,

Thank you very much for your quick responses. I implemented a common
super class for my view controllers now and added the following
method, following your suggestions:

- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if (self.navigationController) {
self.navigationController.navigationBar.tintColor =
TTSTYLEVAR(navigationBarTintColor);
}
}

While this does solve my problem for now, it surely feels like a bad
work-around, though.

Anyway, thanks again.

Christian.

Exactly - it's bad layering, the view reaches up to its parent and twiddles a property that is logically part of the parent view, not itself.

Also, for what it's worth, you could use a category to override viewWillAppear, instead of inheritance.

I used a category to solve the exact problem.

Yes, I thought about using a category, too. But I already had a super
class in place that all affected view controllers were descending
from. Also, I noticed that controllers inheriting from
TTViewController were not affected and I was afraid to break something
down that branch of classes...
