}
@end

.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    
    //初始化背景图
    [self initBackGroundView];
}
#pragma -mark -functions
-(void)initBackGroundView
{
    Aarray = [[NSMutableArray alloc] initWithObjects:@"+",@"我",@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",@"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z",@"#",nil];
    
    //tableView
    tableview = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 460-44-10-10-20) style:UITableViewStylePlain];
    tableview.tag = 101;
    tableview.delegate = self;

    [self.view addSubview:tableview];
    
    //searchView
    searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    tableview.tableHeaderView = searchBar;
    searchBar.showsScopeBar = YES;
    searchBar.placeholder = @"在全部关注中搜索...";
    
    //搜索的时候会有左侧滑动的效果
    searchControl = [[UISearchDisplayController alloc]initWithSearchBar:searchBar contentsController:self];
    searchControl.delegate = self;
