PageController和TableView

Question

我有一个页面控制器，该方法pageAction定义如下：

-(void)pageAction:(UIPageControl*)control
{       
    NSLog(@"page changed"); 
    [self getVehicules];
    [self.tableViewVehiculesPossedes release];

    int page = pageControlVehiculePossedee.currentPage;
    NSLog(@"page %d", page);
    [self loadScrollViewWithPage:page];

    CGRect frame = pageControlVehiculePossedee.frame;
    frame.origin.x = (vosvehiculeScrollView.frame.size.width * page);
    [vosvehiculeScrollView scrollRectToVisible:frame animated:YES];

    pageControlUsed = YES;
}

每次更改页面时，我都需要显示带有一些标签的tableview。这是代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self getVehicules];

    vosvehiculeScrollView.pagingEnabled = YES;

    vosvehiculeScrollView.showsHorizontalScrollIndicator = NO;
    vosvehiculeScrollView.showsVerticalScrollIndicator = NO;
    vosvehiculeScrollView.scrollsToTop = NO;

    pageControlVehiculePossedee.numberOfPages=[vehiculesPossede count];
    pageControlVehiculePossedee.currentPage=0;

    [self loadScrollViewWithPage:0];
    [pageControlVehiculePossedee addTarget:self action:@selector(pageAction:) forControlEvents:UIControlEventValueChanged];

    votreVehiculeLabel.text=@"Votre véhicule";
    vehiculesPossedesArray = [[NSMutableArray alloc] initWithObjects:@"Annee modele", @"Transmission",@"Carburant", nil];

}

- (void) loadScrollViewWithPage: (int) page {
    if (page < 0) return;
    if (page >= [vehiculesPossede count]) return;    

    tableViewVehiculesPossedes=[[UITableView alloc] initWithFrame:CGRectMake(3, 80, 315, 171) style:UITableViewStyleGrouped];
    tableViewVehiculesPossedes.tag=page;
    tableViewVehiculesPossedes.bounces=NO;
    tableViewVehiculesPossedes.backgroundColor=[UIColor clearColor];
    [tableViewVehiculesPossedes setDelegate:self];
    [tableViewVehiculesPossedes setDataSource:self];        
    [self.vosvehiculeScrollView addSubview:tableViewVehiculesPossedes];

    nameVehiculeLabel.text=[[vehiculesPossede objectAtIndex:page] valueForKey:@"modele"];

    self.transmissionString=[[vehiculesPossede objectAtIndex:page]valueForKey:@"transmision"];
    self.carburantString=[[vehiculesPossede objectAtIndex:page] valueForKey:@"carburant"];    
    self.anneeModelString=[[vehiculesPossede objectAtIndex:page] valueForKey:@"modele_annee"];
    self.anneeString=[[vehiculesPossede objectAtIndex:page]valueForKey:@"annee"];

    if(page==0){
        NSLog(@"0"); 
        self.transmissionString=@"ttt";
    }
    else NSLog(@"1");
}

问题在于，即使我将[self.tableViewVehiculesPossedes release];放在更改页面方法上，tableView也会显示为叠加层，而标签中的文字也会叠加。如果要显示新页面，我该如何处理tableview以使其消失？

请帮助我......我花了很多时间：|

如果我得到了正确的话，我认为你应该在loadScrollViewWithPage中使用alloc创建一个ivar，当切换页面时，你应该通过调用它来从视图中删除它：

[mytableview removeFromSuperview];

很可能你应该照顾它，以及我在你的代码中看不到它。
