顺便把索引和tableView dataSource的代理方法也贴一下：

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return self.contacts.count; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.contacts[section] count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *identifier = @"contactCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier]; } cell.imageView.image = [UIImage imageNamed:@"default_head"]; cell.textLabel.text = [self.contacts objectAtIndex:indexPath.section][indexPath.row]; return cell; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { return [_indexArray objectAtIndex:section]; } - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { return _indexArray; } //索引列点击事件 - (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index { return index; } |
还有两个很重要的方法：
下面这个方法是[theCollation sectionForObject:p collationStringSelector:@selector(getFirstLetter)]; 是这里的p对象要实现的方法，我这里的p是NSString,你也可以用其他对象例如Person。

NSString *ret = @""; if (![self canBeConvertedToEncoding: NSASCIIStringEncoding]) {//如果是英语 if ([[self letters] length]>2) { ret = [[self letters] substringToIndex:1]; } } else { ret = [NSString stringWithFormat:@"%c",[self characterAtIndex:0]]; } return ret; } |
下面这个方法是NSString得类别方法

- (NSString *)letters{ NSMutableString *letterString = [NSMutableString string]; int len = [self length]; for (int i = 0;i < len;i++) { NSString *oneChar = [[self substringFromIndex:i] substringToIndex:1]; if (![oneChar canBeConvertedToEncoding:NSASCIIStringEncoding]) { NSArray *temA = makePinYin2([oneChar characterAtIndex:0]); if ([temA count]>0) { oneChar = [temA objectAtIndex:0]; } } [letterString appendString:oneChar]; } return letterString; } |
