UITableViewCell changes accessory view changes on scroll - ios

Question

I am trying to create tableview with UISwitch for some specific rows and AccessoryDisclosureIndicator for rest of cells.
I get the desired result as one check in following code.But the issue is , when i scroll the table view abruptly then the position of switch changes .. Which is undesired how can i get rid of this.
Please do reply to this thread
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
int _fontSize = fontSize;
NSArray *switchSettings = [[NSUserDefaults standardUserDefaults] arrayForKey:#"switchGeneralSettings"];
NSLog(#"switch settings :%#",switchSettings);
static NSString *cellIdentifier = #"generalSettingsTableViewCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
NSLog(#"*******************1*************");
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
// code to additionally configure cell for multiple other UI components..
if(indexPath.row == 3 || indexPath.row == 4 || indexPath.row == 5 || indexPath.row == 6 || indexPath.row == 7)
{
NSLog(#"switch*******************%d*************",indexPath.row);
switchObj = [[UISwitch alloc] initWithFrame:CGRectZero];
switchObj.tag = indexPath.row + 20002;
cell.accessoryView = switchObj;
[switchObj addTarget: self action: #selector(flip:) forControlEvents:UIControlEventValueChanged];
[switchObj release];
}
else
{
NSLog(#"indicator*******************%d*************",indexPath.row);
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
}
else
{
if(indexPath.row == 3 || indexPath.row == 4 || indexPath.row == 5 || indexPath.row == 6 || indexPath.row == 7)
{
NSLog(#"*******************2*************");
countSwitch = 0;
switchObj = (UISwitch *)[cell.contentView viewWithTag:indexPath.row + 20002];
// switch
[switchObj setOn:NO];
if ([switchSettings count]>0) {
NSString *settingState = [switchSettings objectAtIndex:countSwitch];
if ([settingState isEqualToString:#"ON"]) {
[switchObj setOn:YES];
}
}
countSwitch++;
}
}
// confiure the cell here...
NSLog(#"*******************3*************");
NSString *cellTextLabel = [listGeneralSettings objectAtIndex:indexPath.row];
cell.textLabel.text = cellTextLabel;
cell.textLabel.font = [UIFont systemFontOfSize:_fontSize];
cell.detailTextLabel.text = [listDetailGeneralSettings objectAtIndex:indexPath.row];
NSLog(#" cell.detailTextLabel.text :%#", cell.detailTextLabel.text);
NSLog(#"*******************end*************");
return cell;
}

Here cellone is tableviewCell, in that cell you can add uiswitch
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath*)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
// ... some text label stuff deleted here.
cell.opaque = NO;
cell.selectionStyle = UITableViewCellSelectionStyleGray;
[cell setBackgroundColor: [UIColor colorWithPatternImage:[UIImage imageNamed:#"row_2_blank.png"]]];
// [cell prepareForReuse];
}
if (indexPath.row == 0)
{
selectAllB.tag=100;
[selectAllB addTarget:self action:#selector(click:)forControlEvents:UIControlEventTouchUpInside];
[cellOne setBackgroundColor: [UIColor colorWithPatternImage:[UIImage imageNamed:#"row_2_blank.png"]]];
cellOne.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cellOne;
}
return cell;
}
likewise you can use many tableview cell inwhich you can add ui elements accordingly

You're only updating the cell when it's first created. You need to update it every time. Try it like this:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
int _fontSize = fontSize;
NSArray *switchSettings = [[NSUserDefaults standardUserDefaults] arrayForKey:#"switchGeneralSettings"];
NSLog(#"switch settings :%#",switchSettings);
static NSString *cellIdentifier = #"generalSettingsTableViewCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
NSLog(#"*******************1*************");
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
// code to additionally configure cell for multiple other UI components..
// configure the cell here...
if(indexPath.row == 3 || indexPath.row == 4 || indexPath.row == 5 || indexPath.row == 6 || indexPath.row == 7)
{
NSLog(#"switch*******************%d*************",indexPath.row);
switchObj = [[UISwitch alloc] initWithFrame:CGRectZero];
switchObj.tag = indexPath.row + 20002;
cell.accessoryView = switchObj;
[switchObj addTarget: self action: #selector(flip:) forControlEvents:UIControlEventValueChanged];
[switchObj release];
}
else
{
NSLog(#"indicator*******************%d*************",indexPath.row);
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
if(indexPath.row == 3 || indexPath.row == 4 || indexPath.row == 5 || indexPath.row == 6 || indexPath.row == 7)
{
NSLog(#"*******************2*************");
countSwitch = 0;
switchObj = (UISwitch *)[cell.contentView viewWithTag:indexPath.row + 20002];
// switch
[switchObj setOn:NO];
if ([switchSettings count]>0) {
NSString *settingState = [switchSettings objectAtIndex:countSwitch];
if ([settingState isEqualToString:#"ON"]) {
[switchObj setOn:YES];
}
}
countSwitch++;
}
NSLog(#"*******************3*************");
NSString *cellTextLabel = [listGeneralSettings objectAtIndex:indexPath.row];
cell.textLabel.text = cellTextLabel;
cell.textLabel.font = [UIFont systemFontOfSize:_fontSize];
cell.detailTextLabel.text = [listDetailGeneralSettings objectAtIndex:indexPath.row];
NSLog(#" cell.detailTextLabel.text :%#", cell.detailTextLabel.text);
NSLog(#"*******************end*************");
return cell;
}
