如何解决如何在UITableView中使用UISegmentedControl
| 我想分为两个部分，像这样 降级段将在tableView中显示降级苍蝇，复出段将显示复出苍蝇。能否请我解释一下我该怎么做？我应该制作2个tableView还是仅制作一个？谢谢解决方法
您可以为此使用一个UITableView并在segmentcontrolindexchange方法上重新加载表数据。
- (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(100,20) ];
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;
}
}
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;
}
}
}
