如何在目标c中以编程方式设置选项卡栏项目标题? [英] How to set tab bar item title programmatically in objective c?

问题描述

我想以编程方式将标题设置为选项卡项，但是它不起作用.我的代码如下:

I want to set title to tab item programatically, but it not works. My code is below:

- (IBAction)tab1Click:(id)sender {
    myTabBarController = [[UITabBarController alloc] init];        
    view2Controller = [[View2Controller alloc] init]; 
    [view2Controller setTitle:@"title"];
    view3Controller = [[View3Controller alloc] init];  
    deneme = [[ViewController alloc] init];  

    myTabBarController.viewControllers = [NSArray arrayWithObjects:deneme, view2Controller,view3Controller, nil]; 
    [self.view addSubview:myTabBarController.view];    
    myTabBarController.selectedIndex=1;
}

推荐答案

您可以轻松设置所有UITabBar图标.您可以在viewWillAppear:方法中完成此操作:

You can set all the UITabBar icons in an easy way. You can do this in your viewWillAppear: method:

[[self.tabBarController.tabBar.items objectAtIndex:0] setTitle:NSLocalizedString(@"BotonMapas", @"comment")];

[[self.tabBarController.tabBar.items objectAtIndex:1] setTitle:NSLocalizedString(@"BotonRA", @"comment")];

[[self.tabBarController.tabBar.items objectAtIndex:2] setTitle:NSLocalizedString(@"BotonEstado", @"comment")];

[[self.tabBarController.tabBar.items objectAtIndex:3] setTitle:NSLocalizedString(@"LabelInfo", @"comment")];

Swift 3.1解决方案

Swift 3.1 Solution

self.tabBarController?.tabBar.items?[0].title = NSLocalizedString("BotonMapas", comment: "comment")
self.tabBarController?.tabBar.items?[1].title = NSLocalizedString("BotonRA", comment: "comment")
self.tabBarController?.tabBar.items?[2].title = NSLocalizedString("BotonEstado", comment: "comment")
self.tabBarController?.tabBar.items?[3].title = NSLocalizedString("LabelInfo", comment: "comment")
