有时候需要用到城市列表，作为地址选择，所以写了个demo。
核心代码：
#pragma mark - 获取城市数据-(void)getCityData{    NSString *path=[[NSBundle mainBundle] pathForResource:@"citydict"                                                   ofType:@"plist"];    self.cities = [NSMutableDictionary dictionaryWithContentsOfFile:path];        [self.keys addObjectsFromArray:[[self.cities allKeys] sortedArrayUsingSelector:@selector(compare:)]];        //添加热门城市    NSString *strHot = @"热";    [self.keys insertObject:strHot atIndex:0];    [self.cities setObject:_arrayHotCity forKey:strHot];}#pragma mark - tableView-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{    return 20.0;}-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{    UIView *bgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];    bgView.backgroundColor = [UIColor lightGrayColor];        UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(13, 0, 250, 20)];    titleLabel.backgroundColor = [UIColor clearColor];    titleLabel.textColor = [UIColor blackColor];    titleLabel.font = [UIFont systemFontOfSize:12];        NSString *key = [_keys objectAtIndex:section];    if ([key rangeOfString:@"热"].location != NSNotFound) {        titleLabel.text = @"热门城市";    }    else        titleLabel.text = key;        [bgView addSubview:titleLabel];        return bgView;}- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{    return _keys;}- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{    // Return the number of sections.    return [_keys count];}- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    // Return the number of rows in the section.    NSString *key = [_keys objectAtIndex:section];    NSArray *citySection = [_cities objectForKey:key];    return [citySection count];}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{    static NSString *CellIdentifier = @"Cell";        NSString *key = [_keys objectAtIndex:indexPath.section];        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];    if (cell == nil) {        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;        cell.backgroundColor = [UIColor clearColor];        cell.contentView.backgroundColor = [UIColor clearColor];        cell.selectionStyle = UITableViewCellSelectionStyleNone;                [cell.textLabel setTextColor:[UIColor blackColor]];        cell.textLabel.font = [UIFont systemFontOfSize:18];    }    cell.textLabel.text = [[_cities objectForKey:key] objectAtIndex:indexPath.row];    return cell;}
