一起使用UITabBarController和UINavigationController

Question

在選項卡欄視圖之后單擊視圖時，具有2個選項卡的最佳實踐或好方法是如何類似於UINavigationController。

是否為每個選項卡制作UINavigationController？

標簽欄的創建方式如下：

// Create the tab bar text and images
AViewController *viewA = [[AViewController alloc] init];
BViewController *viewB = [[BViewController alloc] init];

UITabBarItem *tabA = [[UITabBarItem alloc] initWithTitle:@"A" image:[UIImage imageNamed:@"a.png"] tag:1];
UITabBarItem *tabB = [[UITabBarItem alloc] initWithTitle:@"B" image:[UIImage imageNamed:@"b.png"] tag:2]

viewA.tabBarItem = tabA;
viewB.tabBarItem = tabB;

NSArray* controllers = [NSArray arrayWithObjects:viewA, viewB, nil];
self.viewControllers = controllers;

為了進行導航，您需要像這樣為每個創建UINavigationController

更新：現在嘗試

AViewController *viewA = [[AViewController alloc] init];
BViewController *viewB = [[BViewController alloc] init];

UINavigationController *navA = [[UINavigationController alloc]initWithRootViewController:viewA];
UINavigationController *navB = [[UINavigationController alloc]initWithRootViewController:viewA];

UITabBarItem *tabA = [[UITabBarItem alloc] initWithTitle:@"A" image:[UIImage imageNamed:@"a.png"] tag:1];
UITabBarItem *tabB = [[UITabBarItem alloc] initWithTitle:@"B" image:[UIImage imageNamed:@"b.png"] tag:2]

tabA.tabBarItem = tabA;
tabB.tabBarItem = tabB;

NSArray* controllers = [NSArray arrayWithObjects:navA, navB, nil];
self.viewControllers = controllers;
