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;
}
