Unable to change color of UISearchDisplayController - ios6

Question

I'm using UISearchDisplayControlleron UInavigationBar but the background color of UISearchDisplayController is not matching the color of uinavigationbar. i used the following code in ma ViewDidLoad but no change I'm unable to change the color of UISearchDisplayController
self.searchDisplayController.searchBar.tintColor = [UIColor clearColor];

Answer 1

A UISearchDisplayController is not an interface element. It is a controller, not a view. It has no color.

Answer 2

What I did was I created a UISearchBar subclass and in IB made the searchBar belonging to the UISearchDisplayController part of that subclass. From there I was able to change the tintColor and backgroundColor. The reason I needed this was because the UISearchBar was not displaying correctly within a UINavigationBar and this was the only way I could think of on, how to do it.
Edit
Your actually able to do this relatively easy with UISearchDisplayController's initializer, initWithSearchBar:contentsController:, however you'll still need to subclass UISearchBar.
Here is the Code I used. Now if your performing this through IB you only need to use initWithCoder: but I created a setup method. Just incase, I need to use it again, in places other than IB.
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
// Initialization code
[self setup];
}
return self;
}
-(id) initWithCoder:(NSCoder *)aDecoder {
if (self = [super initWithCoder:aDecoder]) {
[self setup];
}
return self;
}
-(id)init {
if (self = [super init]) {
[self setup];
}
return self;
}
-(void) setup {
self.backgroundColor = [UIColor clearColor];
self.tintColor = [UIColor clearColor];
for (UIView * view in self.subviews) {
if ([view isMemberOfClass:NSClassFromString(#"UISearchBarBackground")]) {
view.alpha = 0.0;
}
}
}
