ios - ABPeoplePickerNavigationController 搜索栏颜色并且不会改变

Question

I'm trying to change the color of the search bar orange and the bar tint color to white when a contact get selected.

不管我一直在尝试什么，什么都没有改变，它就像这样卡住了（后退按钮不是白色的）。

在 AppDelegate 中：

[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTintColor:[UIColor whiteColor]];
[[UINavigationBar appearanceWhenContainedIn:[UINavigationController class], nil] setBarTintColor:OrangeOfficialColor];

[[UINavigationBar appearance] setBarTintColor:OrangeOfficialColor];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

弹出视图时：

ABPeoplePickerNavigationController *contactsPicker = [[ABPeoplePickerNavigationController alloc] init];
    contactsPicker.peoplePickerDelegate = self;
    contactsPicker.displayedProperties = @[[NSNumber numberWithInt:kABPersonPhoneProperty]];

    [contactsPicker.searchDisplayController.searchBar setBarTintColor:OrangeOfficialColor];
    [contactsPicker.searchDisplayController.searchBar setTintColor:[UIColor whiteColor]];

    [self presentViewController:contactsPicker animated:YES completion:nil];

开始使用 Xcode 6（iOS 8 SDK）和 iOS 7 应用程序后，我遇到了同样的问题。这是我的解决方法：

[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue" size:16.0f], NSForegroundColorAttributeName : [UIColor blueColor]} forState:UIControlStateNormal];
