#pragma -mark -------------用于处理searchBar委托的方法，用于加载所有的分组数据的显示---------------

-(void)resetSearch{
    
    self.teams=self.allTeams;
    NSMutableArray *allKeys=[[NSMutableArray alloc]init];
    [allKeys addObjectsFromArray:[[teams allKeys]sortedArrayUsingSelector:@selector(compare:)]];
    self.teamsname=allKeys;
    [allKeys release];
}

#pragma -mark -------------用于加载资源文件，用于视图的初始化的过程中---------------
- (void)viewDidLoad
{
    [super viewDidLoad];
    NSBundle *bundle=[NSBundle mainBundle];
    NSData *data=[[NSData alloc]initWithContentsOfFile:
                  [bundle pathForResource:@"2" ofType:@"jpg"]];//找到NSBundle的某一资源
    UIImage *img=[UIImage imageWithData:data];//创建了可用的图像对象
    [self.view setBackgroundColor:[UIColor colorWithPatternImage:img]];//UIColor colorWithPatternImage:方法是把图片转化为color类型  将背景换做提供的图片
    NSString *plistPath = [bundle pathForResource:@"足球队dictionary" ofType:@"plist"];
    NSMutableDictionary *dic=[[NSMutableDictionary alloc]initWithContentsOfFile:plistPath];
    self.allTeams =dic;
    self.teamsname=[[dic allKeys]sortedArrayUsingSelector:@selector(compare:)];
    [dic release];
    [self resetSearch];
    
}

#pragma -mark -------------用于UITableViewDataSource方法的实现---------------

#pragma -mark 显示每个分段下有几行

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    
      NSString *name = [teamsname objectAtIndex:section];
      NSArray *sectionOfDatas=[[teams objectForKey:name]sortedArrayUsingSelector:@selector(compare:)];
      return [sectionOfDatas count];
}

// Row display. Implementers should *always* try to reuse cells by setting each cell‘s reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier:
// Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)

#pragma -mark 显示某个索引下某列的某一行的显示
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    
    NSUInteger  section=[indexPath section];
    NSUInteger  row=[indexPath row];
    NSString *name = [teamsname objectAtIndex:section];
    NSArray *sectionOfDatas=[[teams objectForKey:name]sortedArrayUsingSelector:@selector(compare:)];
    static NSString *CellIdentify=@"CellIdentify";
    UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:CellIdentify];
    if (cell==nil) {
        cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentify]autorelease];
    }
   cell.textLabel.text=[sectionOfDatas objectAtIndex:row];
   return cell;
}

#pragma -mark 显示总分段的个数
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView// Default is 1 if not implemented
{
    return [teamsname count];
}

#pragma -mark 显示每个分段的名称
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;// fixed font style. use custom view (UILabel) if you want something different
{
    NSString *name = [teamsname objectAtIndex:section];
    return name;
}

#pragma -mark 显示每个分段结束的标志
- (NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section{
    
    return @"";
}
// Index

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView// return list of section titles to display in section index view (e.g. "ABCD...Z#")
{
    
    return teamsname;
}

#pragma -mark -------------用于UITableViewDelegate方法的实现---------------

#pragma -mark 显示用户操作的选定索引的某一行值

// Called after the user changes the selection.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    
    NSUInteger section=[indexPath section];
    NSUInteger row=[indexPath row];
    NSString *name = [teamsname objectAtIndex:section];
    NSArray *sectionOfDatas=[[teams objectForKey:name]sortedArrayUsingSelector:@selector(compare:)];
    NSString *message=[[NSString alloc]initWithFormat:@"你选择了%@ %@队",name,[sectionOfDatas objectAtIndex:row]];
    UIAlertView *view =[[UIAlertView alloc]initWithTitle:@"你最喜欢的队" message:message delegate:self cancelButtonTitle:@"确定" otherButtonTitles: nil];
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    [view show];
    [view release];
    [message release];
}

#pragma -mark -------------用于SearchBarDelegate方法的实现---------------

#pragma -mark 通过组名来搜索这一组的情况

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText // called when text changes (including clear)
{
    
    if ([searchText isEqualToString:@""]) {
        
        [self resetSearch];
        return;
    }
    NSMutableDictionary *dict=[[NSMutableDictionary alloc]init];
    
    for(NSString *key in self.teams){
        
        NSMutableArray *array=[allTeams objectForKey:key];
        NSMutableArray *newTeams=[[NSMutableArray alloc]init];
        for (NSString *teamname in array) {
            if ([teamname rangeOfString:searchText options:NSCaseInsensitiveSearch].location!=NSNotFound) {
                [newTeams addObject:teamname];
            }
        }
        if ([newTeams count]>0) {
            [dict setObject:newTeams forKey:key];
        }
        [newTeams release];
    }
    self.teamsname=[[dict allKeys]sortedArrayUsingSelector:@selector(compare:)];
    self.teams=dict;
    [dict release];
}

-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{
    
    [self resetSearch];
}


//------------------------------------------------------------------------------------------------------///
- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    
}


#pragma -mark -------------用于处理属性的内存空间的释放处理---------------
-(void)viewDidUnload{
    
    self.teamsname=nil;
    self.teams=nil;
    self.allTeams=nil;
}

- (void)dealloc
{
    [teams release];
    [teamsname release];
    [allTeams release];
    [super dealloc];
}
