Move UITableViewCell - ios

Question

Hi everyone I am a newbie to iOS.
I have implemented a UITableView with 3 sections in UITableViewController. And I have displayed the section rows to each section.
- (void)viewDidLoad
{
[super viewDidLoad];
self.clearsSelectionOnViewWillAppear = NO;
self.navigationItem.rightBarButtonItem = self.editButtonItem;
sectionTittle=[[NSMutableArray alloc]initWithObjects:#"Real Madrid",#"Barcelona",#"Liverpool", nil];
firstSection=[[NSMutableArray alloc]initWithObjects:#"Cr7",#"Garath Bale",#"Pepe",
nil];
secondSection=[[NSMutableArray alloc]initWithObjects:#"Lionel Messi",#"Neymar",#"Pique",
nil];
thirdSection=[[NSMutableArray alloc]initWithObjects:#"Gerrard",#"Saurez",#"Lallana",
nil];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return sectionTittle.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if(section==0)
{
return [firstSection count];
}
if(section==1)
{
return [secondSection count];
}
if(section==2)
{
return [thirdSection count];
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"hi" forIndexPath:indexPath];
cell.textLabel.textColor=[UIColor brownColor];
if (indexPath.section == 0)
{
cell.textLabel.text=[firstSection objectAtIndex:indexPath.row];
}
if (indexPath.section == 1)
{
cell.textLabel.text = [secondSection objectAtIndex:indexPath.row];
}
if (indexPath.section == 2)
{
cell.textLabel.text = [thirdSection objectAtIndex:indexPath.row];
}
// Configure the cell...
return cell;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [sectionTittle objectAtIndex:section];
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the item to be re-orderable.
return YES;
}
Now my output looks like this:
I want to move the rows between the these 3 sections. How can I do it..? While I try doing it the row moves between the section, but while saving it creates a problem.
How can i go through it..?
Thanks

Answer 1

You need to utilise UITableView re-ordering capacity. The cells can be re-ordered across sections.
To enable re-ordering mode:
[self.tableView setEditing:TRUE animated:TRUE];
This enables the TableView in editing mode which includes enables deletion mode along with re-ordering. If you do not want the deletion mode implement:
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return UITableViewCellEditingStyleNone;
}
The re-order support accessory view is shown if you have implemented moveRowAtIndexPath like, for your case:
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath
{
// Logic to change data source
NSMutableArray *deleteFrom = [self getDataSourceArrayFromIndexPath:sourceIndexPath];
NSMutableArray *addTo = [self getDataSourceArrayFromIndexPath:destinationIndexPath];
[addTo insertObject:[deleteFrom objectAtIndex:sourceIndexPath.row] atIndex:destinationIndexPath.row];
[deleteFrom removeObjectAtIndex:sourceIndexPath.row];
}
where getDataSourceArrayFromIndexPath is:
-(NSMutableArray*) getDataSourceArrayFromIndexPath:(NSIndexPath*) index
{
switch (index.section) {
case 0:
return self.firstSection;
break;
case 1:
return self.secondSection;
break;
case 2:
return self.thirdSection;
break;
default:
break;
}
return nil;
}

Answer 2

Use This Code
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath
{
NSMutableArray *arrayTemp=[arrayMain objectAtIndex:sourceIndexPath.row];
[arrayVisibleCountryList removeObjectAtIndex:sourceIndexPath.row];
[arrayVisibleCountryList insertObject:arrayTemp atIndex:destinationIndexPath.row];
}
- (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath
{
//Uncomment these lines to enable moving a row just within it's current section
if ([sourceIndexPath section] != [proposedDestinationIndexPath section])
{
proposedDestinationIndexPath = sourceIndexPath;
}
return proposedDestinationIndexPath;
}

You can use below tableView method. It moves your cell from sourceIndexPath to destinationIndexPath.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath;
