objective-c - 如何以编程方式将标题设置为标签栏项目？

Question

我尝试了这个但它不起作用我看不到标签栏项目..我该如何解决这个问题？谢谢你的帮助。

- (void)viewDidLoad
{
[super viewDidLoad];
 // Do any additional setup after loading the view from its nib.

 myTabBarController = [[UITabBarController alloc] init];        
 tab1 = [[ZiyaretFormTab1 alloc] initWithNibName:@"ZiyaretFormTab1" bundle:nil];   
 tab2 = [[ZiyaretFormTab2 alloc] initWithNibName:@"ZiyaretFormTab2" bundle:nil];   
 tab3 = [[ZiyaretFormTab3 alloc] initWithNibName:@"ZiyaretFormTab3" bundle:nil];  
 tab4 = [[ZiyaretFormTab4 alloc] initWithNibName:@"ZiyaretFormTab4" bundle:nil];    
 tab5 = [[ZiyaretFormTab5 alloc] initWithNibName:@"ZiyaretFormTab5" bundle:nil];  

 myTabBarController.viewControllers = [NSArray arrayWithObjects: tab1,    tab2,tab3,tab4,tab5,nil]; 
 UITabBarItem *tabItem = [[[myTabBarController tabBar] items] objectAtIndex:1];
 [tabItem setTitle:@"theTitle"];

 [self.view addSubview:myTabBarController.view];    
 myTabBarController.selectedIndex=0;

}

在进入选项卡(ZiyaretFormTab1 到 ZiyaretFormTab5)的每个 View Controller 中，将这段代码插入到 initWithNib 或 viewDidLoad 函数中。

    UITabBarItem * tabtitle = [[UITabBarItem alloc] initWithTitle: @"title"
                                                            image: nil //or your icon 
                                                              tag: 0];

    [self setTabBarItem: tabtitle];
