ios - UIBarButtonItem 样式普通更改字体

Question

改变

NSDictionary * barButtonAppearanceDict = @{UITextAttributeFont : font};
    [[UIBarButtonItem appearance] setTitleTextAttributes:barButtonAppearanceDict forState:UIControlStateNormal];

使用纯...时不影响 UIBarButtonItem

如何更改普通样式 UIBarButtonItem 的字体

这仍然适用于 iOS6

Answer 1

然而，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，您可以试试这个:

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

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

您确定在您的 AppDelegate 类中实现了它吗？ (例如在 didFinishLaunchingWithOptions 方法中)
