Uncheck row automatically when table scrolled - ios

Question

When I scroll UITableView my tableview cells automatically uncheck. But when I press done button it give me selected rows I can't understand why is this happening.
My Tableview code is as below :
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
idArray = [[NSMutableArray alloc]init];
NSLog(#"Cat Array : %#",catArray);
isSelectAllBtnClicked = NO;
serviceArray = [[NSArray alloc]initWithObjects:#"Anal", #"Cuffed", #"Foreplay", #"Masturbation", #"Scat", #"Blindfolded",#"Deep throat", #"French Kissing", #"Missionary", #"Shower for 2", #"Bottom", #"Dinner Date", #"Full Bondage", #"Mutual Masturbation", #"Spanking", #"Boy on Boy", #"Dirty Talk",#"Girl on Girl", #"On top", #"Strap on", #"Choking", #"Doggy", #"Girlfriend Experience", #"Oral", #"Striptease", #"CIM", #"Dominate", #"Golden Shower",#"Oral Mutual", #"Submissive", #"COB", #"Fantasy", #"Kissing", #"Overnight", #"Top", #"COF", #"Fetish", #"Light Bondage", #"Rim me",#"Touching", #"Couples", #"Fisting", #"Lingerie", #"Rim you", #"Toys for me", #"Cuddling", #"Foot fetish", #"Massage", #"Role Play", #"Toys for you", nil];
[myTableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *reuseIdentifier = #"reuseIdentifier";
UITableViewCell *cell = [[UITableViewCell alloc]init];
if (cell != NULL)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier];
}
cell.selectionStyle = UITableViewCellEditingStyleNone;
cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"list_row_bg.png"]] autorelease];
UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:#"service"];
if ([strValue isEqualToString:#"service"])
{
catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
topHaderLabel.text = #"Choose Services";
}
else
{
catListLbl.text = [catArray objectAtIndex:indexPath.row];
topHaderLabel.text = #"Choose Category";
}
catListLbl.textColor = [UIColor colorWithRed:244/255.0 green:29/255.0 blue:94/255.0 alpha:1.0];
catListLbl.backgroundColor = [UIColor clearColor];
[cell addSubview:catListLbl];
if (isSelectAllBtnClicked) {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:#"checkbox_check.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(#"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
[myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
[self tableView:myTableView didSelectRowAtIndexPath:indexPath];
}
else {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:#"checkbox.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(#"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int buttonTag = indexPath.row + 200;
//NSLog(#"%i",buttonTag);
UIButton *tempBtn = (UIButton *)[self.view viewWithTag:buttonTag];
[tempBtn setBackgroundImage:[UIImage imageNamed:#"checkbox_check.png"]forState:UIControlStateNormal];
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
int buttonTag = indexPath.row + 200;
NSLog(#"%i",buttonTag);
UIButton *tempBtn = (UIButton *)[self.view viewWithTag:buttonTag];
[tempBtn setBackgroundImage:[UIImage imageNamed:#"checkbox.png"]forState:UIControlStateNormal];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
int count;
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:#"service"];
if ([strValue isEqualToString:#"service"])
{
count = [serviceArray count];
}
else
{
count = [catArray count];
}
return count;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 40;
}
thanks in advance.

Answer 1

when ever you scroll the table
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
method executes and you have not mentioned any condition by which it can be judged that this row was previously selected or not. you have to insert a condition along with indexPath.row and check whether it is prviously selected or not

Answer 2

try like this ,when you scroll the tableview every time isSelectAllBtnClicked value is 0 that's why every time button changed.
when you scroll the table every time new cell created try to avoid that one
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:#"%d",indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell.selectionStyle = UITableViewCellEditingStyleNone;
cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"list_row_bg.png"]] autorelease];
UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:#"service"];
if ([strValue isEqualToString:#"service"])
{
catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
topHaderLabel.text = #"Choose Services";
}
else
{
catListLbl.text = [catArray objectAtIndex:indexPath.row];
topHaderLabel.text = #"Choose Category";
}
catListLbl.textColor = [UIColor colorWithRed:244/255.0 green:29/255.0 blue:94/255.0 alpha:1.0];
catListLbl.backgroundColor = [UIColor clearColor];
[cell addSubview:catListLbl];
if (isSelectAllBtnClicked) {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:#"checkbox_check.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(#"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
[myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
[self tableView:myTableView didSelectRowAtIndexPath:indexPath];
}
else {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:#"checkbox.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(#"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
}
}
}
