推荐答案

试试这段代码：在Swift 3中测试。

Try this code: Tested in Swift 3.

注意：方法1仅适用，如果您的VC嵌入了navigationController。在您的情况下，您只使用navigationBar来显示title.So，请使用方法2.

Note: Method 1 works only, If your VC embedded with navigationController.In your case you only using navigationBar to show title.So, use method 2.

方法1：

 navigationController?.navigationBar.setTitleVerticalPositionAdjustment(5, for: UIBarMetrics.default) // set any number you want between -20 to 15

方法2：

 navigationBar.setTitleVerticalPositionAdjustment(10, for: UIBarMetrics.default) // navigationBar is the name of your navBar..
