ABAddressBook将值存储在NSDictionary中 [英] ABAddressBook store values in NSDictionary

问题描述

我有一个在UITableView中显示ABAddressBook个联系人的应用程序.目前，我正在将联系人读入NSDictionary，但是对于某些用户来说，这似乎崩溃了，我怀疑这是内存问题.

I have an app that displays ABAddressBook contacts in a UITableView. Currently I'm reading the contacts into an NSDictionary, however this appears to crash for some users, which I suspect is a memory issue.

是否有另一种方法可以在UITableView中显示ABAddressBook个联系人，而无需先将它们存储在NSDictionary中或使用ABPeoplePicker?

Is there another approach to display ABAddressBook contacts in a UITableView without either first storing them in an NSDictionary or using ABPeoplePicker?

推荐答案

您可以使用以下方式，

ABAddressBookRef ab = ABAddressBookCreateWithOptions(NULL, NULL);
NSArray *arrTemp = (NSArray *)ABAddressBookCopyArrayOfAllPeople(ab);

以上两行将为您在iPhone上的所有联系人创建一个数组.

The above 2 lines will create an array for all your contacts on the iPhone.

现在，您要显示的联系人的任何属性都可以使用以下代码显示.例如，我要显示所有联系人的名字，然后创建一个名为arrContact的Mutable数组.

Now whatever property of a contact you want to display you can display by using the below code. For example, I want to display the first name of all contacts and then create one Mutable array called it arrContact.

NSMutableArray *arrContact = [[NSMutableArray alloc] init];
for (int i = 0; i < [arrTemp count]; i++) 
{
    NSMutableDictionary *dicContact = [[NSMutableDictionary alloc] init];
    NSString *str = (NSString *) ABRecordCopyValue([arrTemp objectAtIndex:i], kABPersonFirstNameProperty);
    @try 
    {
        [dicContact setObject:str forKey:@"name"];
    }
    @catch (NSException * e) {
        [dicContact release];
        continue;
    }
    [arrContact addObject:dicContact];
    [dicContact release];
}

现在只需使用arrContact数组在表视图中显示它即可.

Now just display it using the arrContact array in a table view..
