UIBarButtonItem不显示禁用状态titleTextAttributes

Question

我正在尝试在textAttributes的{​​{1}}上设置已停用的UIBarButtonItem。

我像这样创建我的项目：

UIToolbar

然而，当我设置NSDictionary *enabledAttrs = @{ NSFontAttributeName : font, NSForegroundColorAttributeName : color }; NSDictionary *disabledAttrs = @{ NSFontAttributeName : font, NSForegroundColorAttributeName : [UIColor grayColor] }; [item setTitleTextAttributes:enabledAttrs forState:UIControlStateNormal]; [item setTitleTextAttributes:disabledAttrs forState:UIControlStateDisabled]; 时，该按钮被禁用（它不会触发其动作）但它不会尊重其item.enabled = NO - 它仍然显示为正常状态。为什么呢？

Answer 1

创建UIButton并使用UIBarbutton进行换行，我认为它应该可行。

UIButton *uiButton = [[UIButton alloc] init];
[uiButton setTitleColor: color1 forState: UIControlStateNormal];
[uiButton setTitleColor: color2 forState: UIControlStateDisabled];

UIBarButtonItem *uiBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:uiButton];
