Apply a Global conditional format to UISearchBar, UINavigationController, UIToolbar in iOS - ios

Question

I'm applying next global format to my app:
-(void)customizeAppearance{
//Customizing UINavigationBar
UIImage *navigationbarImage44 = [[UIImage imageNamed:#"navigationbar_44"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
UIImage *navigationbarImage32 = [[UIImage imageNamed:#"navigationbar_32"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
//Set the background image for *all* UINavigationBars
[[UINavigationBar appearance] setBackgroundImage:navigationbarImage44 forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundImage:navigationbarImage32 forBarMetrics:UIBarMetricsLandscapePhone];
//Customize the titlebar for *all* the navigationBars
[[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0], UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:labelFontName size:0.0], UITextAttributeFont,
nil]];
//Customizing UIToolbar
UIImage *toolbarImage44 = [[UIImage imageNamed:#"toolbar_44"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
UIImage *toolbarImage32 = [[UIImage imageNamed:#"toolbar_32"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UIToolbar appearance] setBackgroundImage:toolbarImage44 forToolbarPosition:UIToolbarPositionAny
barMetrics:UIBarMetricsDefault];
[[UIToolbar appearance] setBackgroundImage:toolbarImage32 forToolbarPosition:UIToolbarPositionAny
barMetrics:UIBarMetricsLandscapePhone];
//Customizing UIBarButtonItem
UIImage *button30 = [[UIImage imageNamed:#"buttonitem_30"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
UIImage *button24 = [[UIImage imageNamed:#"buttonitem_24"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
[[UIBarButtonItem appearance] setBackgroundImage:button30 forState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setBackgroundImage:button24 forState:UIControlStateNormal
barMetrics:UIBarMetricsLandscapePhone];
//Customizing UIBarButtonItem BackButton
[[UIBarButtonItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0], UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:labelFontName size:0.0], UITextAttributeFont,
nil]forState:UIControlStateNormal];
UIImage *buttonBack30 = [[UIImage imageNamed:#"backbuttonitem_30"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 13, 0, 5)];
UIImage *buttonBack24 = [[UIImage imageNamed:#"backbuttonitem_24"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 12, 0, 5)];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:buttonBack30
forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:buttonBack24
forState:UIControlStateNormal barMetrics:UIBarMetricsLandscapePhone];
//Customizing UISegmentedControl
[[UISegmentedControl appearance] setTintColor:(UIColorFromRGB(toolbarTintColor))];
//Customizing UISearchBar
[[UISearchBar appearance] setBackgroundImage:navigationbarImage44];
}
and I'm calling this at my AppDelegate.m method
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[self customizeAppearance];
return YES;
}
The question is:
How do I condition all this general format if the viewController is not inside an iPad popup???
I don't want my popups to share original format, I want them with UINavigationBars, UIToolbars, UIBarButtonItems.. in black color as always
thanks in advance for the support

Answer 1

Instead of using appearance you can use appearanceWhenContainedIn:. So instead of
[[UINavigationBar appearance] setBackgroundImage:navigationbarImage44 forBarMetrics:UIBarMetricsDefault];
do
[[UINavigationBar appearanceWhenContainedIn:[CustomViewController class]] setBackgroundImage:navigationbarImage44 forBarMetrics:UIBarMetricsDefault];
which will restrict the appearance changes to only UINavigationBar instances contained in CustomViewController. You may want to check out this question for clarification on how to use appearanceWhenContainedIn for things like UIBarButtonItem.
