如何更改纯样式UIBarButtonItem 的字体

这仍然适用于iOS6

Answer 1

但是，这对我有用（使用普通的BarButtonItem），刚刚对其进行了测试：

[self.myBarButtonItem setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  [UIFont fontWithName:@"Helvetica" size:22.0],NSFontAttributeName,
  nil]forState:UIControlStateNormal];

要使用外观代理，您可以尝试以下操作：

 NSDictionary *attrDict = [NSDictionary dictionaryWithObject: [UIFont fontWithName:@"Helvetica" size:22.0] forKey: UITextAttributeFont];
[[UIBarButtonItem appearance] setTitleTextAttributes: attrDict
                                        forState: UIControlStateDisabled];
[[UIBarButtonItem appearance] setTitleTextAttributes: attrDict
                                        forState: UIControlStateNormal];

你确定，你在AppDelegate类中实现了这一点吗？（例如didFinishLaunchingWithOptions方法）

Answer 2

我在应用程序委托中设置了以下内容，效果很好：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[UIBarButtonItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"Avenir" size:21.0]} forState:UIControlStateNormal];
}
