tabBarController在更改视图时设置为nil,但始终在窗口中



我目前在导航控制器、选项卡栏控制器中使用表视图。当我在表格视图的细节视图上时,我想在细节视图之间"滑动",所以我用UIViewAnimations实现了一个UISwipeGesture来向右/向左滑动。一切都正常,但我有一个小问题。。。当我在从表视图加载的详细信息视图上时,self.tabBarController元素在这里,我有我的选项卡栏,所以我可以在上面添加操作表。但当我滑动时,self-tabBarController现在为零。。。我不知道为什么。。。也许是因为导航控制器?

这是我的代码:

- (id) init
{
    if (self = [super init]) {
        CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];
        UIScrollView *scrollView=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, fullScreenRect.size.width, 367.)];
        scrollView.contentSize=CGSizeMake(320,100);
        scrollView.delegate = self;
        self.view=scrollView;
        self.myView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 367.)];
        self.ButtonSizeM.tag = 0;
        self.ButtonSizeP.tag = 0;
        self.ContentIV = [[UIImageView alloc] init];
    }
    return self;
}
- (void) handleSwipeLeft {
   if (!((self.ancient.tableView.indexPathForSelectedRow.section == ([self.ancient numberOfSectionsInTableView:self.ancient.tableView] - 1)) && (self.ancient.tableView.indexPathForSelectedRow.row == [self.ancient tableView:self.ancient.tableView numberOfRowsInSection:(self.ancient.tableView.indexPathForSelectedRow.section)]-1)))
    {
        NSIndexPath *whereToGo;
        if (self.ancient.tableView.indexPathForSelectedRow.row == [self.ancient tableView:self.ancient.tableView numberOfRowsInSection:(self.ancient.tableView.indexPathForSelectedRow.section)]-1) {
            whereToGo = [NSIndexPath indexPathForRow:0 inSection:(self.ancient.tableView.indexPathForSelectedRow.section)+1];
        }
        else {
            whereToGo = [NSIndexPath indexPathForRow:(self.ancient.tableView.indexPathForSelectedRow.row)+1 inSection:self.ancient.tableView.indexPathForSelectedRow.section];
        }
        CCFASimpleDetail *nextView = [[CCFASimpleDetail alloc] init];
        nextView = [self.ancient tableView:self.ancient.tableView prepareViewForIndexPath:whereToGo];
        [nextView performSelectorOnMainThread:@selector(affichageEnPlace) withObject:nil waitUntilDone:YES];
        float width = self.myView.frame.size.width;
        float height = self.myView.frame.size.height;
        [nextView.view setFrame:CGRectMake(width, 0.0, width, height)];
        [self.view addSubview:nextView.view];
        [UIView animateWithDuration:0.5f delay:0 options:UIViewAnimationCurveEaseInOut animations:^{
                [nextView.view setFrame:self.view.frame];
                [self.myView setFrame:CGRectMake(-width, 0.0, width, height)];
            } completion:^(BOOL finished) {
                [self.myView removeFromSuperview];
                [self.ancient.tableView selectRowAtIndexPath:whereToGo animated:NO scrollPosition:UITableViewScrollPositionTop];
            }
         ];
    }
}

我你可以帮我在刷完后找到我的标签栏:)?

在此处添加视图时:

[self.view addSubview:nextView.view];

UINavigation控制器对此一无所知,也不会为您设置navigationBar和tabBar属性。

您可以做的是让视图获得其超视图(将是self.view),然后向该视图请求tabBarController和来自该视图的tabBar。

我刚刚通过添加解决了我的问题

[self.ancient.navigationController popViewControllerAnimated:NO];
[self.ancient.navigationController pushViewController:nextView animated:NO];

在完成块上!
