我正在尝试从iOS上的地址簿中检索联系人。
在我的NSLOG中一切似乎都没问题，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，但只有3次（我只有3个联系人，在这种情况下计数运行良好）
@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;
}
此处NSLOG输出：

也许还有另一种方法可以用联系人数据填充表格吗？

首先，您还需要为数组，自定义单元格标签获取alloc init。 您无法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。
以这种方式在cellForRow方法中访问数组。
NSMutableDictionary *dic = [retrievedContacts objectAtIndex:indexPath.row];
cell.firstNameLabel.text = [dic objectForKey:@"firstName"];
cell.lastNameLabel.text = [dic objectForKey:@"lastName"];

尝试使用这样的类型转换：
cell.firstNameLabel.text = (NSString*)[retrievedContacts objectAtIndex:indexPath.row];
cell.lastNameLabel.text = (NSString*)[retrievedContacts objectAtIndex:indexPath.row];
或者你可以在添加到数组之前尝试这个：
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。
希望这有帮助。
