今天在调试时发现，tabBarItem的title与NavigtionBar的title存在一定的关联。
当在控制中执行self.title = @"xxxx";或执行xxxVc.title = @"xxxx" 会同时将tabBarItem与Navigation的title同时赋值为xxxx.
代码如下：
//设置tabar视图
- (void)viewDidLoad {
[super viewDidLoad];
MeViewController *me = [[MeViewController alloc] init]; //创建视图控制器
//将me添加到当前视图控制器中
[self addChildVc:me
title:@"与我相关"
image:[UIImage imageNamed:@"tabbar_icon_at"]
selectedImage:[UIImage imageNamed:@"tabbar_icon_at_click"]];
}
- (void)addChildVc:(UIViewController *)childVc
title:(NSString *)text
image:(UIImage *)image
selectedImage:(UIImage *)selectedImage{
childVc.tabBarItem = [childVc.tabBarItem initWithTitle:nil //此处为nil
image:image
selectedImage:selectedImage];
childVc.title = text;
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:childVc];
[self addChildViewController:nav]; //向子视图中添加控制器
}
效果图：
