UITableView 帶右側索引以及Section

//右邊索引 字節數(如果不實現 就不顯示右側索引)
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
    return sectionName;
}

//section （標籤）標題顯示
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
    return [sectionName objectAtIndex:section];
}

//標籤數
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return sectionName.count;
}

// 設置section的高度
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{
    return 40;
}

//點擊右側索引表項時調用
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index {
    NSString *key = [sectionName objectAtIndex:index];
