更改NavigationItem标题大小

Question

我把标题放在nevegationItem中：

let navigationItem = UINavigationItem()
navigationItem.title = "Title"
navigationBar.items = [navigationItem]

这很有效......但是。

如何更改标题文本的大小？？

Answer 1

您可以在导航栏中设置字体...

let font = UIFont(name: "Helvetica", size: 22)!
UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: font]

Answer 2

使用字体属性

更改标题字体

self.navigationController.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "CaviarDreams", size: 20)!]
