更改UITabBarItem中的字体

Question

嗨,我有这个代码,它不起作用,我做错了什么？

- (void)viewDidLoad
{    
    [self.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"AmericanTypewriter" size:20.0f], UITextAttributeFont, nil] forState:UIControlStateDisabled];
}

顺便说一句,这不是我的viewDidLoad中唯一的东西,但我只是想告诉你那些我把它放在哪里.

Answer 1

根据:如何在iOS 5中更改UITabBarItem中的文本颜色

看起来解决方案可能是将消息发送到外观代理,而不是一个项目:

(在iOS 7.0+中已弃用)

[[UITabBarItem appearance] setTitleTextAttributes:@{UITextAttributeFont: [UIFont fontWithName:@"AmericanTypewriter" size:20.0f]} forState:UIControlStateNormal];

对于iOS 7.0+,请使用:

[[UITabBarItem appearance] setTitleTextAttributes:@{NSFontAttributeName: [UIFont fontWithName:@"AmericanTypewriter" size:20.0f]} forState:UIControlStateNormal];

Answer 2

快速的方式,懒惰:

UITabBarItem.appearance().setTitleTextAttributes([NSFontAttributeName: UIFont.systemFontOfSize(10)], forState: .normal)
UITabBarItem.appearance().setTitleTextAttributes([NSFontAttributeName: UIFont.systemFontOfSize(10)], forState: .selected)
