ios - 如何更改 ABPeoplePickerNavigationController 后退按钮颜色？

Question

我ABPeoplePickerNavigationController用来获取所有联系人。我用 更改了 tintColor [[UIBarButtonItem appearanceWhenContainedIn:[ABPeoplePickerNavigationController class], nil] setTintColor:[UIColor whiteColor]];，但是当它推动时，backItem<Contacts仍然是蓝色的。

我试过这个

`[[UIBarButtonItem appearanceWhenContainedIn:[ABPeoplePickerNavigationController class], nil] setTintColor:[UIColor whiteColor]];`  
_picker.topViewController.navigationController.navigationBar.tintColor = [UIColor whiteColor];

和推之前

[[UIBarButtonItem appearanceWhenContainedIn:[ABPersonViewController class], nil] setTintColor:[UIColor whiteColor]];,

它没有用。如何改变它？
