ユーザーの連絡先リストと提案された連絡先を表示するアプリを作成しています。提案された連絡先セクションのチェックボックスをこのように事前に選択したい. 誰か助けて？

今のところ、これを実装する方法がわかりません。試してみると、すべてのチェックボックスが事前に選択されています。
これが cellforRowIndexPath の私のコードです
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
AddressBookCell *cell = nil;
if([tableView isEqual:self.myTableView]){
if([indexPaths objectForKey:indexPath]){
cell = [indexPaths objectForKey:indexPath];
}else{
if([letterArray objectAtIndex:indexPath.section]){
static NSString *TableViewIdentifier = @"MyCells";
cell = [[AddressBookCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TableViewIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.textLabel.text=[[[letterArray objectAtIndex:indexPath.section] objectAtIndex:0] valueForKey:@"name"];
[[letterArray objectAtIndex:indexPath.section] removeObjectAtIndex:0];
cell.checkbox.tag = indexPath.row;
[cell.checkbox addTarget:self action:@selector(checkboxClicked:) forControlEvents:UIControlEventTouchUpInside];
}
}
[indexPaths setObject:cell forKey:indexPath];
}
return cell;
}
これが私のletterArrayのコードです
-(void)setUpContacts{
NSMutableArray *tempArray = [[NSMutableArray alloc]init];
eventController = [[UOEventDetailController alloc]init];
[tempArray addObject:[eventController comparingArrays]];
NSDictionary *alphabet = [[NSDictionary alloc]initWithObjectsAndKeys:[NSNumber numberWithInt:1],@"A",[NSNumber numberWithInt:2],@"B",[NSNumber numberWithInt:3],@"C",[NSNumber numberWithInt:4],@"D",[NSNumber numberWithInt:5],@"E",[NSNumber numberWithInt:6],@"F",[NSNumber numberWithInt:7],@"G",[NSNumber numberWithInt:8],@"H",[NSNumber numberWithInt:9],@"I",[NSNumber numberWithInt:10],@"J",[NSNumber numberWithInt:11],@"K",[NSNumber numberWithInt:12],@"L",[NSNumber numberWithInt:13],@"M",[NSNumber numberWithInt:14],@"N",[NSNumber numberWithInt:15],@"O",[NSNumber numberWithInt:16],@"P",[NSNumber numberWithInt:17],@"Q",[NSNumber numberWithInt:18],@"R",[NSNumber numberWithInt:19],@"S",[NSNumber numberWithInt:20],@"T",[NSNumber numberWithInt:21],@"U",[NSNumber numberWithInt:22],@"V",[NSNumber numberWithInt:23],@"W",[NSNumber numberWithInt:24],@"X",[NSNumber numberWithInt:25],@"Y",[NSNumber numberWithInt:26],@"Z", nil];
for(int i = 1; i<=27; i++){
[tempArray addObject:[NSNull null]];
}
Contacts *contact = [[Contacts alloc]init];
contactNumbers = [contact phoneNumbers];
for (NSDictionary* info in contactNumbers) {
firstLetter = [info objectForKey:@"lastName"];
int index = 27;
if([firstLetter length] > 0){
firstLetter =[NSString stringWithFormat:@"%C",[firstLetter characterAtIndex:0]];
firstLetter= [firstLetter capitalizedString];
if([alphabet objectForKey:firstLetter]){
NSNumber *t = [alphabet valueForKey:firstLetter];
index = [t intValue];
}
}
if([tempArray objectAtIndex:index] == [NSNull null]){
[tempArray insertObject:[NSMutableArray array] atIndex:index];
}
[[tempArray objectAtIndex:index] addObject:info];
}
[alphabet release];
NSArray *alphabet2 = [[NSArray alloc]initWithObjects:@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",@"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z", nil];
NSMutableArray *tempArray2 = [[NSMutableArray alloc]init];
NSMutableArray *titleTemp = [[NSMutableArray alloc]init];
int c = 0;
for(int i = 0; i<=27; i++){
if([tempArray objectAtIndex:i] != [NSNull null]){
if(i == 0){
[titleTemp insertObject:@"Suggested" atIndex:c];
}else if(i == 27){
[titleTemp insertObject:@"Others" atIndex:c];
}else{
int loc = i -1;
[titleTemp insertObject:[alphabet2 objectAtIndex:loc] atIndex:c];
}
[tempArray2 insertObject:[tempArray objectAtIndex:i] atIndex:c];
c++;
}
}
[alphabet2 release];
[tempArray release];
letterArray = tempArray2;
titlePointer = titleTemp;
}
