How and Where to release Customize UITableViewCell?
Thanks

Right after the line:
cell = [[CustomizedCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"CustomizedCell"];
do this:
[cell autorelease];

How to expand and collapse tableviewcell when you click on particular index using autoresize

I want to expand and collapse cell when I clicked on the cell at particular index.
I am using auto resize and the data in the cell is dynamic i.e cell size increase based on label content I am using autoresize not autolayouts.
When I click on the cell the cell size will increase and the size to be increase is also dynamic what depends on the label content.
Please find my below code
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

UIButton not select the correct cell

in my tableview I have a button in the custom cell
I used the delegates to take an action to the button
The button image changes only on the selected cell
My problem is this:
When I press the button happens:
the selected cell is working properly and the button changes correctly (correct)
the second immediately after the selected cell does not change the button (corrected)
the third cell repeats the action of the selected cell (wrong)
This is repeated endlessly do not understand why
 The button should change only the selected cell and not on other non-selected
Can you help me please?
-(void)ButtonPressedGoPoint:(FFCustomCellWithImage *)custom button:(UIButton *)gopointpressed {
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];

When you have memory management issues, there are a number of things you can do:
Re-read the Cocoa memory management rules and make sure that you're following them.
Run the static analyser. This will often pick up places where you have neglected the memory management rules.
Since it appears that you have already enabled NSZombies, insert a breakpoint for [_NSZombie release]. This should hopefully break on the line that is causing the problem.
Edit:
Based on your code, the following line could be the culprit.
[cell.thumbImageView release]; // NOT GOOD
Similarly in your other code you have:
[cell.thumbImageView release]; // NOT GOOD
[cell.catalogName release]; // NOT GOOD
You set an autoreleased object to the thumbImageView and catalogName property of the cell, but you are still trying to release it. This is not how Cocoa memory management works. You don't own cell.thumbImageView or cell.catalogName, so you should not release them.
This problem occurs when you are trying to access the deallocated object. May be your string get released before you accessing it.

[GIFLoader loadGIFData:receivedData to:postGif for:feedTableView]; is a method I created that loads GIFs in a uiimageview. it does that in a background thread and then assigns the Image in the main thread though.
Are there certain practices that I need to follow for async loading?
I am not sure what is wrong with my code. any help would be highly appreciated

The reason you are seeing an image from another cell is that for efficiency's sake, table cells are reused. To get around this problem, set your image to nil after you dequeue the reusable cell in tableView:cellForRowAtIndexPath:.
First, you shouldn't be doing all of that stuff in cellForRowAtIndexPath.
You should subclass UITableViewCell and layout the cell in it's own class.
Cell for row at indexPath should load the cell and populate data. Not layout loads of controls.
Second, once you've done this you can call...
- (void)prepareForReuse
{
self.imageView.image = nil;
}
This will clear the imageView on dequeue of the cell so that if there is a delay loading hte image then you only see a blank imageView rather than the image that was in there previously.

Section on top of section iphone table

I am building a sectioned table, and it is showing up with what looks to be a section on top of a section. You can see on the image that there is a white line under each section.
The image
Here is the code I have to build the table:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [alertList count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier;
if (self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
CellIdentifier = #"CellLandscape";
}
else
{
CellIdentifier = #"Cell";
}
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:CellIdentifier]
autorelease];
//cell.contentView.backgroundColor = [UIColor blackColor];
CGRect frame;
if (self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
frame.origin.x = 370;
//titleFrame.size.width = 320;
}
else
{
frame.origin.x = 220;
//titleFrame.size.width = 220;
}
frame.origin.y = 5;
frame.size.height = 15;
frame.size.width = 74;
UILabel *instLabel = [[UILabel alloc] initWithFrame:frame];
instLabel.tag = 1;
[cell.contentView addSubview:instLabel];
[instLabel release];
}
// Configure the cell.
Alert *p = [alertList objectAtIndex:indexPath.section];
UILabel *instLabel = (UILabel *) [cell.contentView viewWithTag:1];
instLabel.text = [p docDate];
instLabel.textColor = [UIColor blackColor];
[instLabel setFont:[UIFont fontWithName:#"Arial" size:12]];
NSString *path;
if ([[p subscription] isEqual:#"Y"])
{
path = [[NSBundle mainBundle] pathForResource:#"watchlist_on" ofType:#"png"];
}
else
{
path = [[NSBundle mainBundle] pathForResource:#"watchlist_off" ofType:#"png"];
}
//NSLog(#"%#", path);
cell.textLabel.textColor = [UIColor colorWithRed:.847 green:0 blue: 0 alpha: 1];
[cell.textLabel setFont:[UIFont boldSystemFontOfSize:13]];
cell.textLabel.text = [[NSString alloc] initWithFormat:#"%#", [p Name]];
cell.detailTextLabel.textColor = [UIColor blackColor];
[cell.detailTextLabel setFont:[UIFont fontWithName:#"Arial" size: 10]];
cell.detailTextLabel.text = [p docTitle];
cell.detailTextLabel.textColor = [UIColor blackColor];
[cell.detailTextLabel setFont:[UIFont fontWithName:#"Arial" size: 10]];
//cell.detailTextLabel.text = [p docDate];
//cell.imageView.image = [UIImage imageWithContentsOfFile:path];
cell.imageView.userInteractionEnabled = YES;
cell.imageView.userInteractionEnabled = YES;
//cell.imageView.image = [UIImage imageWithContentsOfFile:path];
/// [cell addSubview:imgView];
//cell.textLabel.text = [[NSString alloc] initWithFormat:#"%#, %# G: %#\nDOB: %# Inst: %#", [p lastName], [p firstName], [p gender],
// [p birthDate], [p inst]];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
//only 1 alert at a time
//make doc list from alert object
Document *documentList1 = [[Document alloc] init];
self.documentList = documentList1;
[documentList1 setTitle:[p docTitle]];
[documentList1 setUniqueId:[p uniqueId]];
[documentList1 setDate:[p docDate]];
[documentList1 setRepoOID:[p repoOid]];
[documentArray addObject:documentList];
return cell;
}
Change the table view's separator style to either single line or none - you probably have it on single line etched.
