在特定联系人处打开联系人列表

发布于 2024-11-09 02:18:15 字数 574 浏览 6 评论 0原文

我有一个 iPhone 应用程序，它使用 ABPeoplePickerNavigationController 来选择联系人。第一次选择联系人时，联系人列表显然从顶部的字母“A”下方开始。但是，假设您在“M”下选择了一个联系人；如果您稍后想要更改选择的联系人，我想初始化联系人列表，以便它已经滚动到“M”部分。

这是我用来打开联系人列表的代码：

ABPeoplePickerNavigationController *picker =
                    [[ABPeoplePickerNavigationController alloc] init];
                    picker.peoplePickerDelegate = self;                    
                    [self presentModalViewController:picker animated:YES];
                    [picker release];

我在参考指南中找不到有关如何配置控制器打开位置的滚动偏移的任何信息。

I have an iPhone app that uses a ABPeoplePickerNavigationController to pick out a contact. First time you select a contact, the contact list obviously starts at the top, under the letter 'A'. However, say you selected a contact under 'M'; if you then later want to change which contact is selected, I want to initialise the contact list so that it's already scrolled to the 'M' section.

Here's the code I use to open the contact list:

ABPeoplePickerNavigationController *picker =
                    [[ABPeoplePickerNavigationController alloc] init];
                    picker.peoplePickerDelegate = self;                    
                    [self presentModalViewController:picker animated:YES];
                    [picker release];

I can't find any information in the reference guide on how to configure the scroll offset where the controller opens.

此功能在 ABPeoplePickerNavigationController 中不可用。但是，您可以实现一个自定义的 UITableViewController，它使用 AddressBook 框架来实现此目的。

尝试使用 [ABAddressBook]

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

for( int i = 0 ; i < nPeople ; i++ )
{
    ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i );
    NSString* name = [(NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty) autorelease];
}

Try to use the [ABAddressBook]

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

for( int i = 0 ; i < nPeople ; i++ )
{
    ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i );
    NSString* name = [(NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty) autorelease];
}
