在开发中经常会用到导航器，在导航器中添加标题很简单，如下：  

phase Day 1";  

  

UILabel *titleText = [[UILabel alloc] initWithFrame: CGRectMake(0, 0, 200, 20)];  

    titleText.backgroundColor = [UIColor clearColor];  

    [titleText setFont:[UIFont systemFontOfSize:15.0]];  

    [titleText setText:@"Elimination phase Day 1"];  

    self.navigationItem.titleView=titleText;
