问题描述
我在 UIViewController 中为我的一个标签执行此操作:
I do this in a UIViewController for one of my tabs:
self.title = @"Welcome";
但是，它会覆盖我对 tabBarItem 的所有内容.我试过了:
However, it's overwriting whatever I have for the tabBarItem. I have tried:
self.tabBarItem.title = @"Home";
和
[self.tabBarItem initWithTitle:@"Home" image:[UIImage imageNamed:@"iconHome.png"] tag:0];
但是，self.title 仍然会覆盖 tabBarItem，无论我是否在 设置标题之后尝试后两段代码.代码甚至可以正常运行，但是 self.tabBarItem.title 或 initWithTitle 什么也没做?
But still, self.title overwrites the tabBarItem, regardless of whether I am trying the two latter pieces of code after the title has been set. The code even runs without errors, but the self.tabBarItem.title or initWithTitle doesn't do anything?
推荐答案
好的，我想通了！这就是我正在做的事情:
OK, I figured it out! Here's what I am doing:
self.title = @"Title for TabBarItem"; // TabBarItem.title inherits the viewController's self.title
self.navigationItem.title = @"Title for NavigationBar";
navigationBar 将继承 self.title，除非另外使用 self.navigationItem.title
the navigationBar would inherit self.title, unless otherwise set using self.navigationItem.title
