Question

I’m running my app on my iPhone 4S, I am using custom table view controller and custom table view cell, when i slide the tableview up into whitespace and likewise down into whitespace i get a memory leak, see picture attached

I can’t seem to pinpoint where the problem is, or even if its the cell causing the problem.

I have a SeasonTableViewController,

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{


static NSString *CellIdentifier = @"SeasonTableViewCell";

//SeasonTableViewCell *cell = (SeasonTableViewCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
SeasonTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSLog(@"%@",[tableView dequeueReusableCellWithIdentifier:CellIdentifier]);
if(cell==nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"STableView" owner:self options:nil];

    //cell = [[[SeasonTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];

    cell = (SeasonTableViewCell*)[nib objectAtIndex:0];
}

Season *season = [seasonTableArray objectAtIndex:[indexPath row]];

cell.label1.text = [NSString stringWithFormat:@"%@",[season season_title]];

cell.contentView.backgroundColor = [UIColor redColor];


return cell;
}

This is the output from the NSLog on NSLog@”%@”,[tableview dequeResuableCellWithIdentifier:…..];

In the above.. I have 5 custom SeasonTableViewCells showing in myTableView, the rest are just the normal white cells with nothing in them,

Below is SeasonTableViewCell,

#import "SeasonTableViewCell.h"

@implementation SeasonTableViewCell
@synthesize label1;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
    // Initialization code
}
return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];

// Configure the view for the selected state
}  

-(void)dealloc
{
[super dealloc];
[label1 release];
//[label2 release];
}

Any help of indication is appreciated and thank you in advance !

This is a known bug in the latest iOS. See this thread on the developer forums (Near the bottom of the thread, an Apple employee explains).
