在UINavigationController中更改后退按钮的默认字体 [英] Change the default font of Back button in UINavigationController

问题描述

我正在尝试将UINavigationController中的Back按钮的默认字体更改为自定义字体

I am trying to change the default font of Back button in UINavigationController to a custom font

UIFont *myCustomFont = [UIFont fontWithName:@"MyCustomFont" size:18];

如何将此自定义字体设置为后退按钮？我浏览了本网站中类似问题的其他答案但没有成功。

How can I set this custom font to the Back Button? I've browsed through other answers to similar questions in this site with no success.

推荐答案

[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:
        @{UITextAttributeTextColor:[UIColor blackColor],
         UITextAttributeTextShadowOffset:[NSValue valueWithUIOffset:UIOffsetMake(0, 1)],
         UITextAttributeTextShadowColor:[UIColor whiteColor],
         UITextAttributeFont: myCustomFont
        }
         forState:UIControlStateNormal];
