我正在尝试从 iOS 上的通讯录中检索联系人。

在我的 NSLOG 中似乎一切正常，但是当我将所有联系人放到 tableview（标签等）时，它只显示白色单元格和附件但 3 次（我只有 3 个联系人，并且在这种情况下工作得很好）

@interface ViewController ()
@end

@implementation ViewController

@synthesize  searchBar,contactsTableView, retrievedContacts;



 - (void)viewDidLoad {

    [super viewDidLoad];

    self.title = @"All Contacts";
    self.tableData = [[NSMutableArray alloc] init];
    retrievedContacts = [[NSMutableArray alloc] init];

    self.contactsTableView.dataSource = self;
    self.contactsTableView.delegate = self;




    [self getPersons];

    [self.contactsTableView reloadData];

}


-(void)getPersons {
   // [retrievedContacts removeAllObjects];
    int i;
    ABAddressBookRef contactBook = ABAddressBookCreate();
    NSMutableArray *allData = (__bridge_transfer NSMutableArray *)(ABAddressBookCopyArrayOfAllPeople(contactBook));
    CFIndex contactNum = CFArrayGetCount((__bridge CFArrayRef)(allData));

    for (i = 0; i < contactNum; i++) {
        ABRecordRef ref = CFArrayGetValueAtIndex((__bridge CFMutableArrayRef)(allData), i);
        firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
        lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);
        phonesNum = ABRecordCopyValue(ref, kABPersonPhoneProperty);
        [retrievedContacts addObject:(__bridge id)(firstName)];
        [retrievedContacts addObject:(__bridge id)(lastName)];
        [retrievedContacts addObject:(__bridge id)(phonesNum)];

        NSLog(@"First name %@", firstName);
        NSLog(@"Last Name %@", lastName);
        NSLog(@"Phone %@", phonesNum);

    }

    NSLog(@"Count Contacts %li", contactNum);
    //self.tableData = retrievedContacts;

}





-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [retrievedContacts count];
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellID = @"Cell";

    abCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];

    if (!cell) {
       cell = [tableView dequeueReusableCellWithIdentifier:cellID];
    }

    cell.firstNameLabel.text = [retrievedContacts objectAtIndex:indexPath.row];
    cell.lastNameLabel.text = [retrievedContacts objectAtIndex:indexPath.row];

    return cell;


}

这里是 NSLOG 输出：

也许还有另一种方法可以用联系人数据填充表格？

谢谢

首先，您需要获取数组的 alloc init，还需要自定义单元格标签。您没有在数组中正确添加数据。

 for (i = 0; i < contactNum; i++) {
        ABRecordRef ref = CFArrayGetValueAtIndex((__bridge CFMutableArrayRef)(allData), i);
        firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
        lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);
        phonesNum = ABRecordCopyValue(ref, kABPersonPhoneProperty);

        NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
        [dic setObject:(__bridge id)(firstName) forKey:@"firstName"];
        [dic setObject:(__bridge id)(lastName) forKey:@"lastName"];
        [dic setObject:(__bridge id)(phonesNum) forKey:@"phonesNum"];
        [retrievedContacts addObject:dic];

        NSLog(@"First name %@", [dic objectForKey:@"firstName"]);
        NSLog(@"Last Name %@", [dic objectForKey:@"lastName"]);
        NSLog(@"Phone %@",[dic objectForKey:@"phonesNum"]);

    }

检查 NSLog 是否正在打印工作。

在 cellForRow 方法中以这种方式访问​​数组。

NSMutableDictionary *dic = [retrievedContacts objectAtIndex:indexPath.row];
cell.firstNameLabel.text = [dic objectForKey:@"firstName"];
    cell.lastNameLabel.text = [dic objectForKey:@"lastName"];

我昨天完成了我的问题。现在一切正常。

    self.contactsTableView.delegate = self;    
}

    }



    cell.firstNameLabel.text = [contacts.firstNames objectAtIndex:indexPath.row]; 
    cell.lastNameLabel.text = [contacts.lastNames objectAtIndex:indexPath.row];

尝试像这样进行类型转换：

cell.firstNameLabel.text = (NSString*)[retrievedContacts objectAtIndex:indexPath.row];
cell.lastNameLabel.text = (NSString*)[retrievedContacts objectAtIndex:indexPath.row];

或者您可以在添加到数组之前尝试此操作：

   NSString *firstName = (NSString *)ABRecordCopyValue(ref, kABPersonFirstNameProperty);
   NSString *lastName = (NSString *)ABRecordCopyValue(ref, kABPersonLastNameProperty);

我使用了类似的代码，它对我有用。

希望这可以帮助。
