objective-c - CNContactPickerViewController 联系人列表偏移问题

Question

说明：如果我设置“[[UIScrollView 外观] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentNever];” 在我的应用程序的其他地方，CNContactPicerViewController 中的前两项将被覆盖并且无法触摸。在当前 Contact Picer 之前设置 UIScrollViewContentInsetAdjustmentAutomatic 将有助于前两项可触摸，但联系人列表的初始位置不正确。

- (IBAction)chooseFromContact:(id)sender {
    if (@available(iOS 11.0, *)){
        [[UIScrollView appearance] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentNever];
    }
    ContactManager *contactManager = [ContactManager sharedInstance];
    [contactManager selectContactAtController:self complection:^(NSString * _Nonnull phone) {
        NSLog(@"Hello World");
    }];
}

// in ContactManager.m
- (void)selectContactAtController:(UIViewController *)controller
                      complection:(void (^)(NSString *))completcion {
    if (@available(iOS 11.0, *)){
        [[UIScrollView appearance] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentAutomatic];
    }
    
    self.contactPicker = [[CNContactPickerViewController alloc] init];
    self.contactPicker.delegate = self;
    [controller presentViewController:self.contactPicker animated:YES completion:nil];
    self.currentViewController = controller;
    self.didselectPhone = completcion;
}
