在某些情况下如何设置具有标题视图的导航项目的标题

Question

I have a navigationItem with a titleView . Now in some conditions I want to use the title property for that navigationItem . How to do that? Any idea?

Here is what I have tried, however is not working:

self.revealViewController().navigationItem.titleView = UIView.init()

self.revealViewController().navigationItem.title = "My Item"

Answer 1

在设置标题之前，需要将titleView设置为nil。

Answer 2

在您的ViewController的viewdidload中，您可以设置标题，例如

  self.title = "your title"

Answer 3

UIView* titleView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 40)];
//titleView.backgroundColor=[UIColor redColor];

self.navigationItem.titleView=titleView;
