Question

我的所有代码都在模拟器中完美运行。显示联系人选择器，当按下联系人时，在获得联系人数据后将其解除。但是，当我在我的设备上尝试此操作时，选择器不会被解除，而是显示所选联系人的详细信息。从那里你可以按下各个属性，如数字和地址，但那些只是转移到相关的应用程序。

用户按下以导入联系人的按钮：

- (IBAction)AddContactPressed:(id)sender {
ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
        // First time access has been granted, add the contact
        contactsAccessible = TRUE;
    });
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
    // The user has previously given access, add the contact
    contactsAccessible = TRUE;
}
else {
    // The user has previously denied access
    // Send an alert telling user to change privacy setting in settings app
}

//Test if contacts have been enabled or not
if (contactsAccessible) {
    //Display contact selection screen
    addressBookController = [[ABPeoplePickerNavigationController alloc] init];
    addressBookController.peoplePickerDelegate = self;
    [self presentViewController:addressBookController animated:YES completion:nil];
}
else{
    //Display text saying the contacts could not be accessed and provide a button to ask again
}
}

以下是联系人选择器的所有代码：

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

//Creating dictionary to store contact info
NSMutableDictionary *contactInfoDict = [[NSMutableDictionary alloc]
                                        initWithObjects:@[@"", @"", @"", @""]
                                        forKeys:@[@"firstName", @"lastName", @"mobileNumber", @"homeNumber"]];
//First name
CFTypeRef generalCFObject;
generalCFObject = ABRecordCopyValue(person, kABPersonFirstNameProperty);
if (generalCFObject) {
    [contactInfoDict setObject:(__bridge_transfer NSString *)generalCFObject forKey:@"firstName"];
    CFRelease(generalCFObject);
}

//Last name
generalCFObject = ABRecordCopyValue(person, kABPersonLastNameProperty);
if (generalCFObject) {
    [contactInfoDict setObject:(__bridge_transfer NSString *)generalCFObject forKey:@"lastName"];
    CFRelease(generalCFObject);
}

//Phone numbers: (home and mobile)
ABMultiValueRef phonesRef = ABRecordCopyValue(person, kABPersonPhoneProperty);
for (int i=0; i < ABMultiValueGetCount(phonesRef); i++) {
    CFStringRef currentPhoneLabel = ABMultiValueCopyLabelAtIndex(phonesRef, i);
    CFStringRef currentPhoneValue = ABMultiValueCopyValueAtIndex(phonesRef, i);

    if (CFStringCompare(currentPhoneLabel, kABPersonPhoneMobileLabel, 0) == kCFCompareEqualTo) {
        [contactInfoDict setObject:(__bridge_transfer NSString *)currentPhoneValue forKey:@"mobileNumber"];
    }

    if (CFStringCompare(currentPhoneLabel, kABHomeLabel, 0) == kCFCompareEqualTo) {
        [contactInfoDict setObject:(__bridge_transfer NSString *)currentPhoneValue forKey:@"homeNumber"];
    }

    CFRelease(currentPhoneLabel);
    CFRelease(currentPhoneValue);
}
CFRelease(phonesRef);

//Getting image if contact has image
if (ABPersonHasImageData(person)) {
    NSData *contactImageData = (__bridge_transfer NSData *)ABPersonCopyImageDataWithFormat(person, kABPersonImageFormatThumbnail);

    [contactInfoDict setObject:contactImageData forKey:@"image"];        
}

//Add contact to array
if (contacts == nil) {
    contacts = [[NSMutableArray alloc] init];
}
[contacts addObject:contactInfoDict];

//Save contact
[userDefaults setObject:contacts forKey:@"Contacts"];

[self dismissViewControllerAnimated:YES completion:nil];

return NO;
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{

return NO;
}

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

Answer 1

原因可能是委托无法调用委托方法。这可能会导致您在模拟器和iPhone上使用不同的iOS。

我最好猜测你在模拟器上使用iOS 8，而在iOS 8下，选择器有一个新的委托方法

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person {

....// do whatever you need here

同时旧的就是你正在使用的。

Answer 2

来自文档：

peoplePickerNavigationController:shouldContinueAfterSelectingPerson:property:identifier:

返回值

是执行所选属性的操作并关闭选择器。

不显示拣货员中的人。

所以这可能是个问题。在模拟器上，第一个方法在设备上被调用而另一个方法被调用。因此，您应该处理两种方法中的选择，并从上述方法中返回YES。

联系选择器在模拟器中工作但不在实际的iPhone上工作
