Received memory warning In UITableView - objective-c

Question

I load a table with images and scroll up and down. After a minute or so, I get a "Received memory warning" notification. After seeing this message a few times, the app crashes.
I load by scrolling position 5 images every time the user scrolls to the bottom of the table.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"aCell";
PostTable_Cell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
CGFloat cellHeight = (screenWidth / 16) * 10 + self.view.frame.size.height * 0.09;
cell = [[PostTable_Cell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier withParentWidth:self.view.frame.size.width withCellHeight:cellHeight withParent:self withPostArray:[postsArray objectAtIndex:indexPath.row] withCurrentIndexPostArray:(int)indexPath.row];
[cell setUserInteractionEnabled:YES];
cell.selectionStyle = UITableViewCellStyleDefault;
tableView.separatorColor = [UIColor blackColor];
return cell;
}
Edit :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"aCell";
PostTable_Cell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
CGFloat cellHeight = (screenWidth / 16) * 10 + self.view.frame.size.height * 0.09;
if (cell == nil)
{
cell = [[PostTable_Cell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier withParentWidth:self.view.frame.size.width withCellHeight:cellHeight withParent:self withPostArray:[postsArray objectAtIndex:indexPath.row] withCurrentIndexPostArray:(int)indexPath.row];
[cell setUserInteractionEnabled:YES];
cell.selectionStyle = UITableViewCellStyleDefault;
tableView.separatorColor = [UIColor blackColor];
}
else
{
[cell reloadCellContetWithParent:self withPostArray:[postsArray objectAtIndex:indexPath.row] withCurrentIndexPostArray:(int)indexPath.row];
}
return cell;
}
Edit 3 :
#implementation PostTable_Cell
- (void)awakeFromNib
{
// Initialization code
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
-(void)dealloc
{
#ifdef DEBUG
NSLog(#"%# destoyed",NSStringFromClass([self class]));
#endif
}
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier withParentWidth:(CGFloat)parentWidth withCellHeight:(CGFloat)celltHeight withParent:(id)parent withPostArray:(id)postArray withCurrentIndexPostArray:(int)IndexNumber
{

if (self)

}
return self;
}

Answer 1

mainDalegate = (Main*)parent;
It looks like this might be your issue. Your cells are not getting released because you are creating a retain cycle.
rules to avoid retain cycles.
