我正在尝试将视图控制器推入当前模式，但没有任何反应。所以，我有一个作为 rootViewController 的 loginController，它推送一个 tabBarControler，然后在其中一个 tabBar 视图中打开一个 presentModal。在 presentModal 我有一个 UITableView 单击推送另一个视图但是当我尝试这样做时没有任何反应。为了更清楚，这里的层次结构：
LoginViewController（作为根视图控制器）>>>push>>> UITabBarController（HomeViewController 和其他两个）>>>打开>>> PackViewController（presentModal）需要通过pushViewController打开另一个视图：
编码：
AppDelegate.m
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
LoginViewController_iPhone *loginViewController = [[LoginViewController_iPhone alloc] init];
self.navigationController = [[[UINavigationController alloc] initWithRootViewController:loginViewController] autorelease];
self.window.rootViewController = self.navigationController;
登录视图控制器.m
- (void)viewDidLoad
{
[super viewDidLoad];
HomeViewController_iPhone *referenciaHomeViewController = [[HomeViewController_iPhone alloc] init];
MapaViewController_iPhone *referenciaMapaViewController = [[MapaViewController_iPhone alloc] init];
GuiaViewController_iPhone *referenciaMidiaViewController = [[GuiaViewController_iPhone alloc] init];
UINavigationController *navHome = [[UINavigationController alloc] initWithRootViewController:referenciaHomeViewController];
UINavigationController *navMapa = [[UINavigationController alloc] initWithRootViewController:referenciaMapaViewController];
UINavigationController *navGuia = [[UINavigationController alloc] initWithRootViewController:referenciaMidiaViewController];
self.tabBarController = [[UITabBarController alloc] init];
[self.tabBarController.tabBar setBackgroundImage:[UIImage imageNamed:@"tabBarBackground"]];
[self.tabBarController.tabBar setSelectionIndicatorImage:[UIImage imageNamed:@"tabBarSelected"]];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navHome, navMapa, navGuia, nil];
}
- (void)login {
[self.navigationController pushViewController:self.tabBarController animated:YES];
}
PackViewController.m (PRESENTMODAL):
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
CompraPackViewController_iPhone *controller = [[CompraPackViewController_iPhone alloc] init];
[self.navigationController pushViewController:controller animated:YES];
[controller release];
}
