在開發(fā)中經(jīng)常會(huì)用到導(dǎo)航器，在導(dǎo)航器中添加標(biāo)題很簡(jiǎn)單，如下：

self.title=@"Elimination phase Day 1";

但是如果題目太長(zhǎng)，后半部分就變成省略號(hào)了，那要實(shí)現(xiàn)自定義字體，代碼和效果如下：

      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; 
    [titleText release];
