IOS: How to prevent a view from getting opened in all cells - ios

Question

I have a rate button. Upon clicking on that button a view containing 5 stars opens. But when I click on rate button of particular cell, particular view opens but some views of other cells also get opens. I want the view containing 5 stars of that particular view only to get opened.
I am attaching the code of that view.
cv = [[ASStarRatingView alloc]initWithFrame:CGRectMake(190, y-5, 140, 30)]; //creat an instance of your custom view
cv.tag = indexPath.row ;
if([delegate.constants.snsrate[indexPath.row] isEqualToString: #"0"])
{
cv.hidden=TRUE;
}
else
{
cv.hidden=FALSE;
}
delegate.constants.selected=1;
[cell addSubview:cv];
And my code to close and open the view.
-(void)Rate_Comment:(UIButton *)sender
{
UIButton *b = (UIButton *)sender;
NSInteger row = b.tag ;
for(int i=0;i<[delegate.constants.snsrate count];i++)
delegate.constants.snsrate[i]= #"0";
delegate.constants.buttontag = row;
UITableViewCell *buttonCell = (UITableViewCell *)[b superview];
UITableView* table = (UITableView *)[buttonCell superview];
NSIndexPath* pathOfTheCell = [table indexPathForCell:buttonCell];
delegate.constants.snsIndexPath = pathOfTheCell;
if(![delegate.constants.user_id isEqualToString:[delegate.constants.snsCreatedBy objectAtIndex:row]])
{
if([[delegate.constants.snstotalrating_count objectAtIndex:row] isEqualToString:#"0"])
{
if(cv.hidden)
{
delegate.constants.snsrate[row]= #"1";
cv.hidden=FALSE;
}
else{
delegate.constants.snsrate[row]= #"0";
cv.hidden=TRUE;
}
[streamTable reloadRowsAtIndexPaths:#[pathOfTheCell] withRowAnimation:UITableViewRowAnimationNone];
}else
{
if(cv.hidden==FALSE)
cv.hidden=TRUE;
}
}
}
I am new to IOS. Please if anyone can help it will be much appreciated.
Thank you in advance.

I assume every cell has a "rate" button and a target method, like this:
// --------------------------------------------------------------------
// Sorry, I'm typing from memory, these code might not be 100% correct
// --------------------------------------------------------------------
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID = #"cell";
MyCustomCell *cell = [tableView dequeueReusableCellForIdentifier:cellID];
if(cell == nil)
{
cell = [[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
// --------------------------------------------------------
// Add the method to execute when tapping on a button
// --------------------------------------------------------
[cell.btnRate addTarget:self action:#selector(showRateControl:) forControlEvent:UIControlEventTouchUpInside];
}
// self.selectedRow should init with -1, since we don't want to show stars
// for the first row if self.selectedRow defaults to 0
if(self.selectedRow == indexPath.row)
{
cell.starsView.alpha = 1;
cell.btnRate.alpha = 0;
}
else
{
cell.starsView.alpha = 0;
cell.btnRate.alpha = 1;
}
return cell;
}
-(void)showRateControl:(id)sender
{
UIButton *rateButton = (UIButton *)sender;
// finding the row which the rate button was tapped
CGPoint rootPoint = [rateButton convertPoint:CGPointZero inView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:rootPoint];
// ------------------------------------------------------------
// here we record the row which the rate button was tapped
// in a property we declared in the .h file (see below)
// ------------------------------------------------------------
self.selectedRow = indexPath.row;
// refresh just the selected row (you could alternatively use self.tableView reloadData)
[self.tableView reloadRowsAtIndexPath:#[indexPath]];
}
In your header file, you can declare your selectedRow property like this:
...
class MyViewController: UIViewController
{
}
#property (nonatomic, assign) NSInteger selectedRow;
#end
In your implementation file's viewDidLoad, don't forget to initialise self.selectedRow to -1:
-(void)viewDidLoad
{
[super viewDidLoad];
...
self.selectedRow = -1;
}
See if that helps.
