我无法以编程方式为我的标签栏控制器设置标题

问题描述

我尝试以编程方式创建标签栏控制器.没关系，但我无法为标签栏项目设置标题.. 我该怎么做?

I try to create tab bar controller as programatically. It is ok but I can not set title to tab bar items.. How can I do this?

- (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];

UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"title" image:nil tag:0];
tab1.tabBarItem = item;

myTabBarController.viewControllers = [NSArray arrayWithObjects: tab1, tab2,tab3,tab4,tab5,nil];


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

}

推荐答案

UITabBarItem *tabItem = [[[myTabBarController tabBar] items] objectAtIndex:1];

此行中的

1 表示，您尝试从数组中获取 second 对象.

1 in this line means, that you try to get second object from array.

UITabBarItem 也有很好的方法 initWithTitle:image:tag:.而 this 是文档的链接它非常有帮助.

Also UITabBarItem has nice method initWithTitle:image:tag:. And this is link to documenttion its very helpfull.

我的解决办法:

1) 创建一些项目:

initWithTitle:image:tag:

2) 使用标签栏方法将它们添加到您的标签栏:

2) Add them to your tabbar with tab bar method:

- (void)setItems:(NSArray *)items animated:(BOOL)animated
