Answer 1

如果我理解你的意思正确，你只需要创建一个带有一个或多个UINavigationController实例的NSArray，并将其分配给UITabBarController的viewControllers属性。

你需要进行调整，但这样的东西可能会起作用：

NSMutableArray* controllers = [NSMutableArray arrayWithCapacity:4];

for (NSUInteger i = 0; i < 4; ++i)
{
    UIViewController* innerController = [[[UIViewController alloc] init] autorelease];
    UINavigationController* outerController = [[[UINavigationController alloc] initWithRootViewController:innerController] autorelease];
    [controllers addObject:outerController];
}

[tabBarController setViewControllers:controllers animated:YES];
