iOS10上的通讯录崩溃 [英] Address Book crash on iOS10

问题描述

从联系人选择器中选择联系人会使iOS10.0中的应用程序崩溃。使用 ABPeoplePickerNavigationController 显示联系人选择器，如下所示：

Selecting a contact from contact picker crashes the app in iOS10.0. Contacts picker is shown using ABPeoplePickerNavigationController like this:

let contactsPicker = ABPeoplePickerNavigationController()
contactsPicker.peoplePickerDelegate = self
self.presentViewController(contactsPicker, animated: true, completion: nil)

这是崩溃日志中的堆栈跟踪：

Here is the stack trace from crash log:

我已经在info.plist中添加了 NSContactsUsageDescription ，如 iOS 10 Beta上的通讯录崩溃，但这没有帮助，我不能使用 CNContactPickerViewController ，因为我需要支持iOS8设备。

I have already added NSContactsUsageDescription in the info.plist as discussed on Contact Address book crash on iOS 10 beta but that didn't help and I can't use CNContactPickerViewController as I need to support iOS8 devices.

来自Erdekhayser的解决方案（ iOS 10 beta ）

From Erdekhayser's solution (Contact Address book crash on iOS 10 beta)

您可以使用此方法检查CNContactPickerViewController是否可用？

you can use this method to check CNContactPickerViewController is available?

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];
    }
