我想为UITabBarController创建一个UIView
- @interface TE : UIViewController <UITabBarControllerDelegate>{
- UITabBarController *tabBarController;
- }
- @property (nonatomic,retain) UITabBarController *tabBarController;
- @end
viewDidLoad方法：
- UIViewController *testVC = [[T1 alloc] init];
- UIViewController *otherVC = [[T2 alloc] init];
- NSMutableArray *topLevelControllers = [[NSMutableArray alloc] init];
- [topLevelControllers addObject: testVC];
- [topLevelControllers addObject: otherVC];
- tabBarController = [[UITabBarController alloc] init];
- tabBarController.delegate = self;
- [tabBarController setViewControllers:topLevelControllers animated:NO];
- tabBarController.selectedIndex = 0;
- self.view = tabBarController.view;
这会创建标签栏控制器,但是当我点击标签栏项目时,我会收到一个错误：
Thread1:Program receive signal: SIGABRT
编辑：我通过下载并修改了http://www.iphonedevcentral.com/create-uitabbarcontroller/版本来解决了这个问题
解决方法
你上面说的你不想在appDelegate中创建tabBarController.为什么不？你会在哪里创建它？ tabBarController必须是根视图控制器,不能是任何其他视图控制器的子级.
Btw,确保你实现：
- - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {
- NSUInteger tabIndex = [tabBarController.viewControllers indexOfObject:viewController];
- if (viewController == [tabBarController.viewControllers objectAtIndex:tabIndex] ) {
- return YES;
- }
- return NO;
- }
