iPhone程序调用系统通讯录选择单个电话号码

为了调用系统的通讯录界面与相应功能,需要引入AddressBook.framework与AddressBookUI.framework,

同时,在源文件中需要包含同文件,.

#import<AddressBook/AddressBook.h>
#import<AddressBookUI/AddressBookUI.h>

首先申明变量:

ABPeoplePickerNavigationController *picker;

在需要的地方调用显示选择联系人界面,同时设置ABPeoplePickerNavigationControllerDelegate委托:

picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[self presentModalViewController:picker animated:YES];// showing the picker

下面的方法在用户选择通讯录一级列表的某一项时被调用,通过person可以获得选中联系人的所有信息,但当选中的联系人有多个号码,而我们又希望用户可以明确的指定一个号码时(如拨打电话),返回YES允许通讯录进入联系人详情界面

- (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker
shouldContinueAfterSelectingPerson:(ABRecordRef)person {
NSLog(@"用户选择了通讯录一级列表的某一项");
return YES;
}

当用户点击某个字段时,会调用如下方法。联系人信息中可能有很多字段,首先需要判断选择的是否为电话号码字段.当满足要求时,获取联系人信息,通过标识符获得用户选择的号码在该联系人号码列表中的索引,最后通过索引获得选中的电话号码。

- (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker
shouldContinueAfterSelectingPerson:(ABRecordRef)person
property:(ABPropertyID)property
identifier:(ABMultiValueIdentifier)identifier
{
if (property == kABPersonPhoneProperty) {
ABMutableMultiValueRef phoneMulti = ABRecordCopyValue(person, property);
int index = ABMultiValueGetIndexForIdentifier(phoneMulti,identifier);
NSString *phone = (NSString*)ABMultiValueCopyValueAtIndex(phoneMulti, index);
//do something

[phone release];
[peoplePicker dismissModalViewControllerAnimated:YES];
}
return NO;
}

最后还需要实现如下方法使得用户在点击"取消"按钮时关闭联系人选择界面:

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
{
[peoplePicker dismissModalViewControllerAnimated:YES];
NSLog(@"回到主页面");
}
