swift——设置navigationitemtitle的内容以及格颜色

1.用UILabel，自定义整个titleview

//    var TitleText = UILabel()

        self.TitleText.frame = CGRectMake(0, 0, 100, 30)
        self.TitleText.text = "账号"
        self.TitleText.font = UIFont.boldSystemFontOfSize(20)
        self.TitleText.textColor = UIColor.whiteColor()
        self.navigationItem.titleView = TitleText

2.只改变字体颜色

        let navigationTitleAttribute: NSDictionary = NSDictionary(object: UIColor.whiteColor(), forKey: NSForegroundColorAttributeName)
        self.navigationItem.title = "账号"
        self.navigationController?.navigationBar.titleTextAttributes = navigationTitleAttribute as? [String : AnyObject]
