ios - Swift 中的外观代理 (iOS)

Question

有没有人尝试过快速使用外观代理？

这种语法不起作用，有没有人想出如何在segmentedControl或UITabBar等控件上设置标题文本属性？我想我很接近

segmentedControl.titleTextAttributesForState(UIControlState.Normal) = 
NSDictionary(objects: [UIFont(name: fontFamilyRegular, size: 16.0)], 
forKeys: [NSFontAttributeName])

Answer 1

这应该这样做：

segmentedControl.setTitleTextAttributes([
    NSFontAttributeName: UIFont(name: "Helvetica", size: 16.0)!,
    NSForegroundColorAttributeName: UIColor.blueColor()
    ], forState: UIControlState.Normal)

Answer 2

确保解开字体 (!)

let font = UIFont(name: "HelveticaNeue-Light", size:15.0)!
UIBarButtonItem.appearance().setTitleTextAttributes([NSFontAttributeName:font,NSForegroundColorAttributeName:UIColor.redColor()], forState: UIControlState.Normal)

Answer 3

对于 XCode 6.1，试试这个：

UITabBarItem.appearance().setTitleTextAttributes(NSDictionary(object: UIFont(name: "Helvetica", size: 16.0)!, forKey: NSFontAttributeName), forState: UIControlState.Normal)
