Question

我在IOS 8人选择器委托代码中遇到了一个奇怪的问题。只有

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController    *)peoplePicker;
{
    [self dismissViewControllerAnimated:YES completion:NULL];
}

正在调用

方法。我已经回顾了其他问题并通过调用旧的IOS 7方法对选择联系人进行了重要的IOS 8委托方法更改

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:   (ABMultiValueIdentifier)identifier {
    [self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person property:property identifier:identifier];
}

但永远不会被召唤。

我在调用viewcontroller didLoad中设置委托，

它在ios 7中完美运行。这是一个故事板应用程序。

我在这里的评论中看到了同样的问题：ABPeoplePickerNavigationController changes with iOS8?

但从未找到答案。显然我身上的某个错误，但我无法找到它。

更新：根据要求，以下是我设置委托的方式：

self.picker = [[ABPeoplePickerNavigationController alloc] init];
self.picker.peoplePickerDelegate = self;

并且，在@interface：

@interface TreatmentsAddEntryTVC :    UITableViewController<UITextViewDelegate,ABPeoplePickerNavigationControllerDelegate>

Answer 1

尝试使用此委托方法，看看它是否命中：

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person;
{
   // yes the below line is deprecated as of iOS 8
   [self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person];
}

Answer 2

我讨厌回答我自己的问题，特别是当答案毫无意义，但感动时：

self.picker = [[ABPeoplePickerNavigationController alloc] init];
self.picker.peoplePickerDelegate = self;

从didLoad到我实际想要显示选择器的方法修复了问题。我已经在SO上看到至少一个其他问题，其中注意到并讨论了这种行为：

Cannot select contact on iOS 8

Answer 3

对于iOS 8.1的项目，我替换了这个方法

trackdatacompvar <- within(trackdatacompvar,
                           { 
                             grpA <- check_if_in_circle(points = cbind(X, Y), 
                                                        x_grpA, y_grpA, rad_grpA + 115)
                             grpB <- check_if_in_circle(points = cbind(X, Y), 
                                                        x_grpB, y_grpB, rad_grpB + 115)
                             grp <- ifelse(grpA, ifelse(grpB, 'D', 'A'),
                                           ifelse(grpB, 'B', 'C'))
                           } )

用这个

-(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person{ 
}

当我选择联系人时，新方法确实出现了。

IOS 8 - ABPeoplePickerNavigationController - 取消委托方法有效，有些则无效
