如何更改普通样式UIBarButtonItem的字体

这仍然适用于iOS6

Answer 1

然而，这适用于我（使用普通的BarButtonItem），刚刚测试过它：

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

对于使用外观代理，您可以尝试：

 NSDictionary *attrDict = [NSDictionary dictionaryWithObject: [UIFont fontWithName:@"Helvetica" size:22.0] forKey: UITextAttributeFont];

[[UIBarButtonItem appearance] setTitleTextAttributes: attrDict
                                        forState: UIControlStateDisabled];
[[UIBarButtonItem appearance] setTitleTextAttributes: attrDict
                                        forState: UIControlStateNormal];

您确定在AppDelegate课程中实现了这一点吗？ （例如在didFinishLaunchingWithOptions - 方法中）

Answer 2

我在appdelegate中设置了以下内容并且效果很好：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    [[UIBarButtonItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"Avenir" size:21.0]} forState:UIControlStateNormal];

}
