Ios ABPeoplePickerNavigationController透明顶栏

我使用标准的ABPeoplePickerNavigationController，当我拖动带有联系人的桌子时，我看到顶部的条是透明的。我解决不了。看起来糟透了

我尝试将[UIColor whiteColor]设置为我能访问的所有内容：导航栏、ABPeoplePickerNavigationController的所有子视图以及它的topViewController的所有子视图。我尝试将不同的栏样式设置为导航栏。没什么帮助

这是代码

@interface MNFindClientVC () <ABPeoplePickerNavigationControllerDelegate>
@property (nonatomic, strong) ABPeoplePickerNavigationController *addressBookController;
-(void)openPhoneBook;
@end

@implementation MNFindClientVC
-(void)viewDidLoad
{
        [super viewDidLoad];
        self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"phonebook"] style:UIBarButtonItemStyleBordered target:self action:@selector(openPhoneBook)];
        self.addressBookController = [[ABPeoplePickerNavigationController alloc] init];
        self.addressBookController.peoplePickerDelegate = self;
}

-(void)openPhoneBook
{
    [self presentViewController:self.addressBookController animated:YES completion:nil];
}
@end

@接口MNFindClientVC（）
@属性（非原子，强）ABPeoplePickerNavigationController*addressBookController；
-（作废）开放电话簿；
@结束
@实现MNFindClientVC
-（无效）viewDidLoad
{
[超级视图下载]；
self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc]initWithImage:[UIImage ImageName:@“phonebook”]样式：UIBarButtonItem样式有边框的目标：自我操作：@selector（openPhoneBook）]；
self.addressBookController=[[ABPeoplePickerNavigationController alloc]init]；
self.addressBookController.peoplePickerDelegate=self；
}
-（作废）openPhoneBook
{
[self-presentViewController:self.addressBookController动画：是完成：无]；
}
@结束

对不起我的英语。谢谢：）

我在使用半透明的UINavigationBar时遇到了同样的问题。使用以下代码（在iOS 8中测试）在ABPeoplePickerNavigationContrller中禁用UINavigationBar的半透明性可以解决此问题：

对不起，它仍然对我有效，你可以注释掉右边的BarbuttonItem行并再次测试。

_addressBookController = [[ABPeoplePickerNavigationController alloc] init];
[_addressBookController setPeoplePickerDelegate:self];

[[UINavigationBar appearanceWhenContainedIn:[ABPeoplePickerNavigationController class], nil] setTranslucent:NO];

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