How to avoid selecting other cells that have the same indexPath - objective-c

Question

I've been struggling with this issue for weeks and still have not found one solution. No one really gave me an answer on SO and have not found anything that helps my issue either.
When making a change of a cell's content's color, position, whatever, other cells with the same indexPath also get modified.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{
static NSString *simpleTableIdentifier = #"cell";
self.cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (self.cell == nil) {
self.cell = [[SearchCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
This is how I create cells. Help..!
EDIT
This is a slide-out view implemented in each cell. When you swipe to right on a cell, it shows up from the left but even though only the selected cell's content should be modified, several other cell's slide-out menu also come out.
This is how I implement slide-out menu in my custom cell class.
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.optionView = [[OptionView alloc]initWithFrame:CGRectMake(0, 0, self.contentView.frame.size.width , self.contentView.frame.size.width)];
self.optionView.delegate = self;
[self.contentView addSubview: self.optionView];
OptionView' delegate - called when swiped to the right
-(void)handleGesture:(UISwipeGestureRecognizer*)shouldOpenMenu{
POPSpringAnimation *anim = [POPSpringAnimation animation];
anim.property = [POPAnimatableProperty propertyWithName:kPOPViewFrame];
anim.toValue = [NSValue valueWithCGRect:CGRectMake(-self.frame.size.width/4, 0, self.optionView0.frame.size.width, self.optionView0.frame.size.height)];
anim.springBounciness = 11;
anim.springSpeed = 5;
[self.optionView0.layer pop_addAnimation:anim forKey:#"spring0"];

First, each tableview cell has different index path.
Second, you never want to save cells at class level properties. Create them locally and return from cellForIndexPath:. Your table view will take care of the cell thereon.
Third, and very important, cells are reused. So, you should reset the cell before using it. For instance, if you are setting cell colour to red in some condition and then you move the table down and this cell gets discarded and new cell is rendered by re-using the discarded cell. You would want to reset the cell colour to clear if you are not setting cell colour for that row.
Follow these rules and you should be able to fix your issue.
