如何在Swift中更改 NavigationBar 字体?
How do I change the NavigationBar font in Swift?
这是我到目前为止尝试过的，但是收到一个错误(我已经正确地对项目实现了CaviarDreams):
This is what I have tried so far, but receiving an error (I have correctly implemented CaviarDreams to the project):
self.navigationController.navigationBar.titleTextAttributes = NSFontAttributeName[UIFont .fontWithName(CaviarDreams.ttf, size: 20)]
错误说:Use of unresolved identifier 'CaviarDreams
对不起，如果问题很严重.
Sorry if the question is extremely bad.
推荐答案
尝试一下:
self.navigationController.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "CaviarDreams", size: 20)!]
现在，必须解开UIFont才能在此处使用.
Now, UIFont must be unwrapped to be able to be used here.
Swift 5 (+安全处理可选的UIFont)
Swift 5 (+ safe handling of optional UIFont)
self.navigationController?.navigationBar.titleTextAttributes = [ NSAttributedString.Key.font: UIFont(name: "Caviar-Dreams", size: 20) ?? UIFont.systemFont(ofSize: 20)]
