Question

我正在尝试将一个视图控制器推入一个nowmodal但没有任何事情发生。所以，我有一个loginController作为rootViewController，它推送一个tabBarControler，然后在tabBar视图中打开一个presentModal。在presentModal中我有一个UITableView，当点击推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，这里是层次结构：

LoginViewController（作为根视图控制器）＆gt;＆gt;＆gt; push＆gt;＆gt;＆gt; UITabBarController（HomeViewController和另外两个）＆gt;＆gt;＆gt;打开＆gt;＆gt;＆gt; PackViewController（presentModal）需要通过pushViewController打开另一个视图：

代码：

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;

LoginViewController.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];

}

执行当前模态时，需要提供一个导航控制器，其根视图控制器是表视图控制器。

如何处理需要使用navigationController的tabBar中的presentModal
