Question

我想制作两个片段，就像这样

enter image description here

deparature段将在tableView中显示deverature fly，并且将返回的回归段返回。请问我能解释一下我该怎么做？我应该制作2个tableView还是只制作一个？谢谢

Answer 1

您可以将One UITableView用于此目的，并在segmentcontrolindexchange方法上重新加载表数据。查看代码

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 1;
}

-(NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section
{ if(segment.selectedSegmentIndex==0)
{
    return [List count];
}
    else
        if (segment.selectedSegmentIndex==1) {
            return[List1 count];

        }

    return 0;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
           cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];



    lbl1 = [[UILabel alloc]initWithFrame:CGRectMake(200, 10, 100, 20) ];

    // Configure the cell...
lbl =[[UILabel alloc]initWithFrame:CGRectMake(100, 10, 100, 20) ];
    if(segment.selectedSegmentIndex==0)
    {
    cell.textLabel.text=[List objectAtIndex:indexPath.row];

        lbl.text = [List3 objectAtIndex:indexPath.row];
        [cell.contentView addSubview:lbl];

        lbl1.text = [List objectAtIndex:indexPath.row];
        [cell.contentView addSubview:lbl1];
    }
    else if(segment.selectedSegmentIndex==1) {
        cell.textLabel.text=[List1 objectAtIndex:indexPath.row];

        lbl.text = [List objectAtIndex:indexPath.row];
        [cell.contentView addSubview:lbl];
    }


    return cell;
}




-(IBAction) segmentedControlIndexChanged
{
    switch (self.segment.selectedSegmentIndex) {
        case 0:
            i=0;
            [table reloadData];
            break;
        case 1:
            i=1;

            [table reloadData];
        default:
            break;
    }



}

Answer 2

您可以这样做......一个UITableView需要您更改数据源以及分段控件何时更改。或者首选，您将拥有2个带有自己的控制器的UITableView，并使用分段控件简单地切换它们的可见性。

Answer 3

遵循Apple设计指南的另一种方法是用工具栏控件替换分段控件，然后可以使用UIToolBarController中的构建来管理UI堆栈并为每个状态提供不同的视图。

    My case was also same (UISegment Control and UITableView with two prototype cells.  


    class DashBoardViewController: UIViewController,UITableViewDataSource {

        @IBOutlet weak var dashBoardSegment: UISegmentedControl!
        @IBOutlet weak var dashBoardTableView: UITableView!


        //TableView Variables
        var CellIdentifier: String = "dashBoardTableReportsCellID"
        var cell:UITableViewCell?
    var rowCount:Int?


        // MARK: - Table view data source
        func numberOfSectionsInTableView(tableView: UITableView) -> Int {
            return 1
        }
        func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

            switch CellIdentifier
            {
            case "dashBoardTableCellID":
                rowCount = 2

            case "dashBoardTableReportsCellID":
                rowCount = 4
            default:
                break;
            }

            return rowCount!
        }
        func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

            switch CellIdentifier
            {
            case "dashBoardTableCellID":
                cell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! 
                print("CELL 1")

            case "dashBoardTableReportsCellID":
                cell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! 
                print("CELL 2")
            default:
                break;
            }
            return cell!
        }


// OR 
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        if (CellIdentifier == "dashBoardTableCellID")
        {
            let surveyCell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! as! DashBoardTableViewCell
            surveyCell.itemDetailLabel.text = "Survey Cell Title"            

            return surveyCell
        }
        else
        {
            let reportsCell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! as! DashBoardTableViewReportsCell


            return reportsCell
        }
      }


    //Mark:- Segment Control Action
        @IBAction func dashBoardSegmentValueChanged(sender: AnyObject) {
            switch dashBoardSegment.selectedSegmentIndex
            {
            case 0:
                CellIdentifier = "dashBoardTableCellID"
                self.dashBoardTableView.reloadData()

            case 1:
                CellIdentifier = "dashBoardTableReportsCellID"
                self.dashBoardTableView.reloadData()
            default:
                break;
            }

        }
