iPhone UINavigationBar使用[UINavigationBar外观]更改所有控制器的字体样式 [英] iPhone UINavigationBar change font style for all controllers with [UINavigationBar appearance]

问题描述

我知道我可以单独更改导航栏的字体，如下所示：更改导航栏的字体

I'm aware that I can individually change the font of a navigation bar as outlined in this answer: Change the navigation bar's font

目前我正在使用更全球化的方法：

Currently I'm using a more global approach:

//in my app delegate:
    [[UINavigationBar appearance] setBarStyle:UIBarStyleBlackTranslucent];

有没有办法全局更改导航栏通过外观对象的字体？

Is there a way to globally change the font that the Navbar through the appearance object?

谢谢！
