i read thru the whole forum maybe im doing something wrong any help would be great

tabController = [[UITabBarController alloc] init]; tabController.delegate = self; [tabController setViewControllers: [NSArray arrayWithObjects: //[[[UINavigationController alloc] initWithRootViewController:[[[SearchTableViewController alloc] init] autorelease]] autorelease], //[[[UINavigationController alloc] initWithRootViewController:[[[SearchPhotosViewController alloc] init] autorelease]] autorelease], //[[[UINavigationController alloc] initWithRootViewController:[[[SearchPhotosViewController alloc] init] autorelease]] autorelease], //[[[UINavigationController alloc] initWithRootViewController:[[[SearchPhotosViewController2 alloc] init] autorelease]] autorelease], [[[UINavigationController alloc] initWithRootViewController:[[[crap2 alloc] init] autorelease]] autorelease], [[[UINavigationController alloc] initWithRootViewController:[[[crap3 alloc] init] autorelease]] autorelease], [[[UINavigationController alloc] initWithRootViewController:[[[crap alloc] init] autorelease]] autorelease], nil]]; //tabCon开发者_如何学Ctroller.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;

//tabController.navigationController.navigationBar.barStyle = UIBarStyleBlack; //tabController.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; //tabController.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent; tabController.navigationController.navigationBar.barStyle = UIBarStyleBlack; [window addSubview:[tabController view]];

For NavigationController, try:

self.navigationController.navigationBar.barStyle = UIBarStyleBlack;

For a Toolbar, try:

[toolbar setTintColor:[UIColor blackColor]];
