Three20 titleForHeaderInSection

以下是我添加的内容。它只是列出了每个字母字符下的所有objectsForCharacters。

- (void)tableViewDidLoadModel:(UITableView*)tableView {
items = [[NSMutableArray alloc] init];
arrayOfCharacters = [[NSMutableArray alloc]init];
objectsForCharacters = [[NSMutableDictionary alloc]init];  
    NSMutableArray *arrayOfNames = [[NSMutableArray alloc]init];
for (Kid_CareAppDelegate_City* post in _searchFeedModel.posts) {
    [arrayOfNames addObject:post.city];
    [items addObject:[TTTableTextItem itemWithText:post.city 
                                               URL:[NSString stringWithFormat:@"tt://city?to=%@",[post.city stringByReplacingOccurrencesOfString:@" " withString:@"+"]]]];
}
for(char c='A';c<='Z';c++){
    [arrayOfCharacters addObject:[NSString stringWithFormat:@"%c",c]];
    [objectsForCharacters setObject:arrayOfNames forKey:[NSString stringWithFormat:@"%c",c]];
}
NSLog(@"Array %@",arrayOfCharacters);
NSLog(@"Dict %@",objectsForCharacters);
    TT_RELEASE_SAFELY(arrayOfNames);
self.items = items;
TT_RELEASE_SAFELY(items);
}
