我正在检索联系人姓名和电话号码。从我的应用程序中的地址簿。我在日志中打印它们,它工作正常。但是当我尝试在表格视图上显示它们时,我得到了异常 NSInvalidArgumentException。我在视图控制器上有一个按钮,按下该按钮,表格视图应该会填充联系人姓名和他们的号码:
- (IBAction)syncContacts:(id)sender
{
ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
for (int i = 0; i < ABAddressBookGetPersonCount(addressBook); i++) {
ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);
NSString *contact = (NSString *)CFBridgingRelease(ABRecordCopyCompositeName(ref));
// NSString* phone = nil;
ABMultiValueRef phoneNumbers = ABRecordCopyValue(ref,kABPersonPhoneProperty);
// if (ABMultiValueGetCount(phoneNumbers) > 0) {
NSString *phone = (__bridge_transfer NSString*)
ABMultiValueCopyValueAtIndex(phoneNumbers, 0);
// }
NSDictionary *curContact=[NSDictionary dictionaryWithObjectsAndKeys:(NSString *)contact,@"Name",phone,@"phone",nil];
[self.phoneContacts addObject:curContact];
}
tableView.delegate = self;
tableView.dataSource = self;
[tableView reloadData];
NSLog(@"%@",self.phoneContacts);
NSLog(@"%i",[self.phoneContacts count]);
}
表格视图方法是:
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.phoneContacts count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
// cell.textLabel.text = [self.phoneContacts objectAtIndex:indexPath.row];
cell = [self.phoneContacts objectAtIndex:indexPath.row];
return cell;
}
表格视图有什么问题?当 phoneContacts 只有名称时,它工作正常。([phoneContacts addObject:contact])。但是现在当我添加字典对象时,它会抛出这个异常。
我做出了改变。
cell = [[self.phoneContacts objectAtIndex:indexPath.row] objectForKey:@"AddressBook"];
现在没有例外。但是屏幕上没有显示任何内容。
这是编辑的方法:
- (IBAction)syncContacts:(id)sender
{
ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
for (int i = 0; i < ABAddressBookGetPersonCount(addressBook); i++) {
ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);
// NSNumber *contact = (NSNumber *)ABRecordCopyComposite();// (ref));
NSString *contact = (NSString *)CFBridgingRelease(ABRecordCopyCompositeName(ref));
// NSString* phone = nil;
ABMultiValueRef phoneNumbers = ABRecordCopyValue(ref,kABPersonPhoneProperty);
// if (ABMultiValueGetCount(phoneNumbers) > 0) {
NSString *phone = (__bridge_transfer NSString*)
ABMultiValueCopyValueAtIndex(phoneNumbers, 0);
// }
// NSDictionary *curContact=[NSDictionary dictionaryWithObjectsAndKeys:(NSString *)contact,@"Name",phone,@"phone",nil];
contact = [contact stringByAppendingString:@" "];
contact = [contact stringByAppendingString:phone];
[self.phoneContacts addObject:contact];
}
tableView.delegate = self;
tableView.dataSource = self;
[tableView reloadData];
}
表格视图保持不变,如原始帖子中所示。它现在正在工作。
