iphone - 同じビューで新しいテーブルを作成する際のテーブル ビュー タグの問題

Question

タグ 1がありUITableViewます。このテーブルを削除して、再びタグ 2 を使用して新しいテーブルを作成すると、シミュレーターでハングアップし、アクションは発生しません。同じタグ1で作成すると、大丈夫です.どんな体でも助けてくれますか?

私のコードは以下です。

- (IBAction)menuTapped:(id)sender {

    UIButton *btn = (UIButton *)sender;

    if (btn.tag==0)
    {
        UIView *subview;
        while ((subview= [[mainView subviews]lastObject])!=nil)

        if ([subview isKindOfClass:[UIView class]]){    
            [subview removeFromSuperview];
        }

        UIView *view=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 320,45)];
        [mainView addSubview:view];
        [view setBackgroundColor:[UIColor darkGrayColor]];

        _btnNavigation=[UIButton buttonWithType:UIButtonTypeCustom];
        _btnNavigation.frame=CGRectMake(10, 9, 30, 25);
        [_btnNavigation setImage:[UIImage imageNamed:@"reveal-icon@2x.png"] forState:UIControlStateNormal];
        [_btnNavigation addTarget:self action:@selector(menuTapped:) forControlEvents:UIControlEventTouchUpInside];
        _btnNavigation.tag=0;

        [view addSubview:_btnNavigation];

        UILabel *lblheading=[[UILabel alloc]initWithFrame:CGRectMake(58, 6, 205,32)];
        [view addSubview:lblheading];
        lblheading.text=@"MY TEAMS";
        lblheading.backgroundColor=[UIColor clearColor];
        lblheading.textColor=[UIColor whiteColor];
        lblheading.textAlignment=NSTextAlignmentCenter;
        lblheading.font=[UIFont fontWithName:@"LeagueGothic-Regular" size:32.0];

        searchBar=[[UISearchBar alloc]initWithFrame:CGRectMake(0, 45, 320, 44)];
        [mainView addSubview:searchBar];
        searchBar.delegate=self;

        _tableTeams=[[UITableView alloc]initWithFrame:CGRectMake(0,90, 320, 326)];
        [mainView addSubview:_tableTeams];
        _tableTeams.delegate=self;

        mainView.hidden=NO;
        if(menuOpen) {

            frame.origin.x = 160;
            menuOpen =NO;

        }
        else
