从Exchange全局地址列表访问联系人时，iOS应用程序崩溃

标签： ios cordova exception cordova-plugins ios10

我在cordova框架上构建了一个应用程序，并且我使用了一个名为cordova-plugin-contacts（https://github.com/apache/cordova-plugin-contacts）的插件来访问联系人的号码。

每当我从联系人中选择联系人时，都会在iOS 9和10中正确选取联系人号码。但是，当我从Exchange全局地址列表中的组联系人访问联系人时，不会发生这种情况。一旦我尝试在iOS9中尝试接收应用程序在iOS10中崩溃，它就可以正常工作。

我试图调试iOS 9和10只是为了看到存在问题的一点，如在iOS 10中，编译代码的异常。在iOS 9中，有一种方法似乎是我选择联系人时首先调用的方法。 

   // Called after a person has been selected by the user.
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person
{
    CDVContactsPicker* picker = (CDVContactsPicker*)peoplePicker;
    NSNumber* pickedId = [NSNumber numberWithInt:ABRecordGetRecordID(person)];

    if (picker.allowsEditing) {
        ABPersonViewController* personController = [[ABPersonViewController alloc] init];
        personController.displayedPerson = person;
        personController.personViewDelegate = self;
        personController.allowsEditing = picker.allowsEditing;
        // store id so can get info in peoplePickerNavigationControllerDidCancel
        picker.pickedContactDictionary = [NSDictionary dictionaryWithObjectsAndKeys:pickedId, kW3ContactId, nil];

        [peoplePicker pushViewController:personController animated:YES];
    } else {
        // Retrieve and return pickedContact information
        CDVContact* pickedContact = [[CDVContact alloc] initFromABRecord:(ABRecordRef)person];
        NSArray* fields = [picker.options objectForKey:@"fields"];
        NSDictionary* returnFields = [[CDVContact class] calcReturnFields:fields];
        picker.pickedContactDictionary = [pickedContact toDictionary:returnFields];

        CDVPluginResult* result = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsDictionary:picker.pickedContactDictionary];
        [self.commandDelegate sendPluginResult:result callbackId:picker.callbackId];

        [[picker presentingViewController] dismissViewControllerAnimated:YES completion:nil];
    }
}

但是，在iOS10中，应用程序似乎在调用该方法之前崩溃了。我收到的例外是：

2016-11-18 11:37:17.301332 myAppName[417:118946] *** Terminating app due to uncaught exception 'CNPropertyNotFetchedException', reason: 'A property was not requested when contact was fetched.'

在调试控制台中我输入了bt，我收到了：

我还附上了一张可能有帮助的图片。联系人工作正常，但在从Exchange服务器选择联系后崩溃了。 Image of the crash. In contacts everything works fine. Only in the exchange server.

任何有关的帮助，都会很棒。

答案 0 :(得分：0)

确保NSContactsUsageDescription位于您应用的info.plist中。

崩溃的原因也可能是因为iOS10为人员选择器使用了不同的类，所以你需要进行如下检查：

if (NSClassFromString(@"CNContactPickerViewController")) {
    // iOS 9, 10, use CNContactPickerViewController
    CNContactPickerViewController *picker = [[CNContactPickerViewController alloc] init];
    picker.delegate = self;
    picker.displayedPropertyKeys = @[CNContactPhoneNumbersKey];
    [pr presentViewController:picker animated:YES completion:nil];
}else{
    // iOS 8 Below, use ABPeoplePickerNavigationController
    ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
    picker.peoplePickerDelegate = self;
    [pr presentViewController:picker animated:YES completion:nil];
}
