我的程序不支持 UIInterfaceOrientation。添加UITabBarItem后程序将不支持UIInterfaceOrientation。请给出解决方案。我还添加了导航控制器。这是我的代码。
-(void) applicationDidFinishLaunching:(UIApplication *)application {
//I create my navigation Controller
//UINavigationController *navigationController;
//I create my TabBar controlelr
tabBarController = [[UITabBarController alloc] init];
// Icreate the array that will contain all the View controlelr
NSMutableArray *localControllersArray = [[NSMutableArray alloc] initWithCapacity:2];
// I create the view controller attached to the first item in the TabBar
sivajitvViewController *firstViewController;
firstViewController = [[sivajitvViewController alloc]init];
navigationController = [[UINavigationController alloc] initWithRootViewController:firstViewController];
//[navigationController.tabBarItem initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:1];
firstViewController.navigationItem.title=@"Gallery";
//viewController.tabBarItem.image = [UIImage imageNamed:@"natural.jpg"];
navigationController.tabBarItem.image = [UIImage imageNamed:@"Gallery.png"];
navigationController.tabBarItem.title = @"Gallery";
//navigationController.headerTitle = @"Some Title";
[localControllersArray addObject:navigationController];
[navigationController release];
[firstViewController release];
// I create the view controller attached to the second item in the TabBar
SecondViewController *secondViewController;
secondViewController = [[SecondViewController alloc] init];
navigationController = [[UINavigationController alloc] initWithRootViewController:secondViewController];
//[navigationController.tabBarItem initWithTabBarSystemItem:UITabBarSystemItemContacts tag:2];
navigationController.tabBarItem.image = [UIImage imageNamed:@"News.png"];
navigationController.tabBarItem.title = @"News";
[localControllersArray addObject:navigationController];
[navigationController release];
[secondViewController release];
// load up our tab bar controller with the view controllers
tabBarController.viewControllers = localControllersArray;
// release the array because the tab bar controller now has it
[localControllersArray release];
// add the tabBarController as a subview in the window
[window addSubview:tabBarController.view];
// need this last line to display the window (and tab bar controller)
[window makeKeyAndVisible];
}
