setting Title for navigation bar in xcode
提问by Anish
I have created a navigation controller programmatically,
我以编程方式创建了一个导航控制器，
//Creating AddViewController Object
addViewController *addView = [[addViewController alloc]init];
UINavigationController *addViewControl = [[UINavigationController alloc]init];
[addViewControl.view addSubview:addView.view];
[self presentModalViewController:addViewControl animated:YES];
But when i add self.title = @"Title" in addViewController class. it is not displaying.
但是当我在 addViewController 类中添加 self.title = @"Title" 时。它没有显示。
i tried with the following,
我尝试了以下内容，
self.navigationItem.title = @"Title";
self.navigationController.navigationBar.topItem.title = @"Title";
But it's not displaying Title.
但它不显示标题。
I think it is possible to do with setting a label. but the above one is direct method.
我认为可以设置标签。但上面的一种是直接方法。
Any Idea..

Try initializing your navigation controller this way:
尝试以这种方式初始化您的导航控制器：
UINavigationController *addViewControl = [[UINavigationController alloc] initWithRootViewController:addView];
[self presentModalViewController:addViewControl animated:YES];
//[addView release];
//[addViewControl release]; // uncomment these two lines if not using ARC
And then set the titleproperty of your addViewControllerclass in the viewWillAppearmethod.
然后在方法中设置类的title属性。addViewControllerviewWillAppear

You should assign the title to the addViewlike addView.title = @"Title";
您应该将标题分配给addView喜欢addView.title = @"Title";
Another way to do it is self.navigationItem.title = @"Title";
另一种方法是 self.navigationItem.title = @"Title";

In the viewController class:
[self setTitle:@"title"];or self.title=@"title";
在 viewController 类中：
[self setTitle:@"title"];或self.title=@"title";

This seem to work fine for me
这对我来说似乎很好用
self.navigationController.navigationBar.topItem.title = @"Title";

Your navigation controller isn't correctly setup:
您的导航控制器设置不正确：
UINavigationController *addViewControl = [[UINavigationController alloc]initWithRootViewController:addView];
// delete this line: [addViewControl.view addSubview:addView.view];

[self.navigationItem setTitle:@"title here"];
