Ios 如何在使用FBSDK共享对话框时更改UIBarButtonItem的色调

我对uibarbuttonite的颜色有问题

我已经设置了

[[uibarbuttonite外观]setTintColor:[UIColor-whiteColor]]用于在应用程序中使用默认颜色

但是在这个屏幕上。它似乎看不见按钮，因为它是白色的！
我使用ViewController中的FBSDKShareDialog show来显示共享弹出屏幕。如何编辑此屏幕的“淡色”

编辑以了解更多信息

作为建议，它仅适用于此屏幕。但实际上我的问题是在我把这个屏幕改成蓝色之后。这将影响发送电子邮件屏幕。所以在电子邮件屏幕上，它似乎也看不到按钮，因为我的导航栏是蓝色的。那是骗子。我使用UIActivityController显示电子邮件屏幕

如果您还没有弄清楚这一点，那么可以使用代理进行

如果（[UINavigationBar conformsToProtocol:@protocol（UIAppearanceContainer）]{[UINavigationBar外观].tintColor=[UIColor whiteColor]；}@Jigar我必须设置
[[UIBarButtonItem外观]setTintColor:[UIColor whiteColor]]因为当用户单击发送到电子邮件时。按钮默认设置为蓝色，我的导航栏颜色也为蓝色。因此，如果（[UINavigationBar conformsToProtocol:@protocol（UIAppearanceContainer）]{[UINavigationBar外观]，[UIColor whiteColor]；}@Jigar我必须设置
