ios联系人信息增删改查

ios6以后，对这个功能做了限制，要申请用户授权，这才对嘛，偷偷摸摸读取我的联系人，我肯定不愿意。

下面说一下具体方法：

1. 引入AddressBook.framework框架, 然后#import <AddressBook/AddressBook.h>

2. 基础知识：

• 因为这个framework是CoreFoundation里面的，所以不受arc的控制，需要自己手动维护，不要忘记release，否则会有内存泄露的问题。
• 在APP安装到设备以后，第一次会弹出提示，然后在Settings->Privacy->contacts里面可以选择是否授权。如果把app卸载，或者重新build之后，则不会再出现提示信息。如果想再次看见那个alert，那么就要Settings->General->Reset->Reset Location&Privacy，就可以了。
• 设置提示的信息，在工程的plist文件中，添加一项key为“Privacy - Contacts Usage Description”，后面的value就会显示在提示中。

3. 下面是读取联系人信息的主要代码：

获取联系人姓名的时候取到的是唯一值，获取电话号码的时候取到的是一个数组，所以要分别做处理，其他信息都有相应的key去对应，详见头文件。

    NSArray *contacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(self.addressBook);    NSMutableString *contactString =[NSMutableString string];    for (id people in contacts) {        NSString *firstName = (__bridge NSString *)ABRecordCopyValue((__bridge ABRecordRef)(people), kABPersonFirstNameProperty);        NSString *lastName = (__bridge NSString *)ABRecordCopyValue((__bridge ABRecordRef)(people), kABPersonLastNameProperty);        ABMultiValueRef phoneNumbers = ABRecordCopyValue((__bridge ABRecordRef)(people), kABPersonPhoneProperty);        for (int i = 0; i < ABMultiValueGetCount(phoneNumbers); i++) {            NSString *phone = (__bridge NSString *)(ABMultiValueCopyValueAtIndex(phoneNumbers, i));        }        CFRelease(phoneNumbers);    }    self.contactListLabel.text = contactString;    if (_addressBook) {        CFRelease(_addressBook);    }

4. 下面是删除联系人的主要代码：

    NSArray *array = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(_addressBook);    for (id obj in array) {        ABRecordRef people = (__bridge ABRecordRef)obj;        NSString *firstName_ab = (__bridge NSString *)ABRecordCopyValue(people, kABPersonFirstNameProperty);        NSString *lastName_ab = (__bridge NSString *)ABRecordCopyValue(people, kABPersonLastNameProperty);        if ([firstName_ab isEqualToString:firstName] && [lastName_ab isEqualToString:lastName]) {            ABAddressBookRemoveRecord(_addressBook, people, NULL);        }        CFRelease(people);    }    if (ABAddressBookSave(_addressBook, NULL)) {        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Done" message:@"Success to delete contact!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];        [alert show];    } else {        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Failed to delete contact!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];        [alert show];    }    if (_addressBook) {        CFRelease(_addressBook);    }

5. 下面是添加联系人的主要代码：

    NSString *firstName = self.firstNameField.text;    NSString *lastName = self.lastNameField.text;    NSString *mobileNumber = self.mobileField.text;    NSArray *phones = [NSArray arrayWithObjects:mobileNumber, nil];    NSArray *phoneLabels = [NSArray arrayWithObjects:@"mobile", nil];    if (firstName.length && lastName.length && mobileNumber.length) {        ABRecordRef person = ABPersonCreate();        ABRecordSetValue(person, kABPersonFirstNameProperty, (__bridge CFTypeRef)(firstName), NULL);        ABRecordSetValue(person, kABPersonLastNameProperty, (__bridge CFTypeRef)(lastName), NULL);        ABMultiValueRef mv = ABMultiValueCreateMutable(kABMultiStringPropertyType);        for (int i = 0; i < [phones count]; i++) {            ABMultiValueIdentifier mvi =            ABMultiValueAddValueAndLabel(mv,                                         (__bridge CFTypeRef)([phones objectAtIndex:i]),                                         (__bridge CFStringRef)([phoneLabels objectAtIndex:i]),                                         &mvi);        }        ABRecordSetValue(person, kABPersonPhoneProperty, mv, NULL);        CFRelease(mv);        ABAddressBookAddRecord(self.addressBook, person, NULL);        if (ABAddressBookSave(self.addressBook, NULL)) {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Done" message:@"Success to save contact!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];            [alert show];        } else {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Failed to save contact!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];            [alert show];        }    }    if (_addressBook) {        CFRelease(_addressBook);    }

6. update 联系人的方法

用到的方法在上面都已经列出了，所以就不在详述了。

7. 调用contacts.

引入AddressBookUI.framework，然后 #import <AddressBookUI/AddressBookUI.h>， 实现一下ABPeoplePickerNavigationControllerDelegate。

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

贴一下调用的代码：

    if (!self.contactPicker) {        self.contactPicker = [[ABPeoplePickerNavigationController alloc] init];        self.contactPicker.modalInPopover = YES;        self.contactPicker.modalPresentationStyle = UIModalPresentationCurrentContext;        self.contactPicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;        self.contactPicker.peoplePickerDelegate = self;    }    [self presentViewController:self.contactPicker animated:YES completion:^{            }];
