Change BarButtonItem Font Using Swift (Xcode 6)
提问by Seth
I am having trouble changing the font in my swift Xcode project of a BarButtonItem that was added to a navigation controller. I was able to change the color of the button without a problem, but the font will not change. Code:
我无法更改已添加到导航控制器的 BarButtonItem 的 Swift Xcode 项目中的字体。我可以毫无问题地更改按钮的颜色，但字体不会改变。代码：
var navTextColor = UIColor(red:0.3, green:0.09, blue:0.05, alpha:1.0)
self.navigationController?.navigationBar.tintColor = navTextColor

If you create and outlet (e.g. @IBOutlet var barButton: UIBarButtonItem!) linked to your UIBarButtonItem, you should be able to change your font type by using setTitleTextAttributeson the outlet.
如果您创建并将插座（例如@IBOutlet var barButton: UIBarButtonItem!）链接到您的UIBarButtonItem，您应该能够通过setTitleTextAttributes在插座上使用来更改您的字体类型。
barButton.setTitleTextAttributes([ NSFontAttributeName: UIFont(name: "Arial", size: 12)!], forState: UIControlState.Normal)

Another easy way to change all TabBarItems font is using this code in ViewDidLoad()of UITabBarController: (No need to create an Outlet )
另一种简单的方法来改变所有TabBarItem的字体在使用此代码ViewDidLoad()的UITabBarController：（无需创建一个插座）
UITabBarItem.appearance().setTitleTextAttributes([NSFontAttributeName: UIFont(name: "IranSansMobile", size: 15)!], for: UIControlState.normal)
