在uiviewcontroller中将uitableviewcontroller添加为子视图时出错

问题描述

我正在做一个简单的应用程序来查看来自json服务器的项目

i'm doing a simple app that views items from a json server

我在一个UIViewController中使用了UISegment来添加不同的子视图

I used UISegment in one UIViewController to add different subview

    - (IBAction)segmentSwitch:(id)sender {
    UISegmentedControl *segmentedControl = (UISegmentedControl *) sender;
    NSInteger selectedSegment = segmentedControl.selectedSegmentIndex;

    if (selectedSegment == 0) {
        instantiateViewControllerWithIdentifier:@"prestige"] animated:NO];

        UIViewController *subController = [self.storyboard instantiateViewControllerWithIdentifier:@"prestige"];
        [mainView addSubview:subController.view];

    }
    else if(selectedSegment == 1)
    {
        instantiateViewControllerWithIdentifier:@"latest"]];
        //[self setView: [self.storyboard instantiateViewControllerWithIdentifier:@"latest"]];
        //UIViewController *subController = [self.storyboard instantiateViewControllerWithIdentifier:@"latest"];
        //[mainView addSubview:subController.view];

        UITableViewController *tableVC =[self.storyboard instantiateViewControllerWithIdentifier:@"latest"];

        [self.view addSubview:tableVC.tableView];

    }
    else if (selectedSegment == 2)
    {
        instantiateViewControllerWithIdentifier:@"contactUs"]];
        UIViewController *subController = [self.storyboard instantiateViewControllerWithIdentifier:@"contactUs"];
        [mainView addSubview:subController.view];
    }
}

当我选择选择第2段来查看时出现错误uitableviewcontroller作为子视图
x代码给我以下错误

my error comes when I select select Segment 2 to view the uitableviewcontroller as subviewx code give me the following error

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"latestCell1";

    latestCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    NSDictionary *latests = [latestArray objectAtIndex:indexPath.row];

    NSString *latest_name_En = [latests objectForKey:@"title_en"];
    NSString *logo1 = [latests objectForKey:@"logo"];
    NSString *img1 = [latests objectForKey:@"img1"];

    NSData *latestsImg1 = [NSData dataWithContentsOfURL:[NSURL URLWithString:img1]];
    NSData *latestsLogo1 = [NSData dataWithContentsOfURL:[NSURL URLWithString:logo1]];    

    cell.latest_name_en1.text = latest_name_En;

    dispatch_async(dispatch_get_main_queue(), ^{

        cell.latest_img1.image = [UIImage imageWithData:latestsImg1];
        cell.latest_logo1.image = [UIImage imageWithData:latestsLogo1];

    });

    return cell;
}

我确信UITableViewController工作正常，因为我试图单独运行它并且它的工作也尝试了没有自定义单元格，它也工作，但使用custon单元格作为子视图，它给出了上面的错误。

I'm sure the UITableViewController is working fine as I tried to run it alone and it work also tried it without custom cell and it worked also but with custon cell as a subview it gives the error above.

推荐答案

感谢您的帮助

我终于明白了我的意思used

I finally figure it out I used

[self addChildViewController:subController];
[mainView addSubview:subController.view];

将tableview作为子视图添加到viewcontroller

to add the tableview to the viewcontroller as subview

它起作用了
