didSelectrow doesn't work with scrollview and tableview (iOS) - iphone

At the moment I'm creating an app which has a scrollview and tableview.
I used the code like here: http://johansorensen.com/articles/touches-and-uiscrollview-inside-a-uitableview.html
but cause of the combination of the scrollview and tableview the didSelectrow function doesn't work anymore.
Thanks for helping!
Please notice: answer clear, I'm not the most experienced iOS developer.

In your case UIScrollView hide your cell, so you can not touch cell of UITableView therefor didSelectRowAtIndexPath method is not work.
Write following code form your link for add scrollView with in UITableView
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 50.0f;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"ScrollCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
UIScrollView *scroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 25, 320, 25)];
scroller.showsHorizontalScrollIndicator = NO;
UILabel *contentLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320*4, 25)];
contentLabel.backgroundColor = [UIColor clearColor];
contentLabel.textColor = [UIColor whiteColor];
NSMutableString *str = [[NSMutableString alloc] init];
for (NSUInteger i = 0; i < 100; i++) { [str appendFormat:#"%i ", i]; }
contentLabel.text = str;
[scroller addSubview:contentLabel];
scroller.contentSize = contentLabel.frame.size;
[cell addSubview:scroller];
}
return cell;
}
and then use
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
It may be useful for you.

NSMutableArray data not loading in tableView in iPhone?

I did XML parsing for the content I obtained from WCF Service. I loaded the data in NSMutableArray using NSXMLParser.Now I want that data to be loaded in tableview in a UIView. But I can see the empty tableview being loaded and data doesn't. Couldn't understand where I am going wrong.
My NSMutableArray is like this:
(
{
UserName="Roy";
Password="126";
},
{
UserName="Joy";
Password="123";
},
{
UserName="Rony";
Password="5983";
}
-------------

)
And the code for UItableView is :
#interface RootViewController : UIViewController<NSXMLParserDelegate,UITableViewDataSource,UITableViewDelegate>
{
NSMutableArray *arr;
UITableView *tableView;
}
- (void)viewDidLoad
{
UITableView* tableView = [[UITableView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:tableView];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [arr count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil)
{
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
}
NSString *tempstring=[arr objectAtIndex:indexPath.row];
cell.textLabel.text= tempstring;
return cell;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 3;
}
I am getting empty tableview with some empty rows. How can i fix this?
hey you just add this code in your cellForRowAtIndexPath delegete:-
EDITED
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil)
{
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
}
SMutableDictionary *d = (NSMutableDictionary *) [arr objectAtIndex:indexPath.row]
UILabel *username = [[UILabel alloc]initWithFrame:CGRectMake(10, 5, 280, 30)];
username.textColor =DARK_VIEW;
username.font=[UIFont boldSystemFontOfSize:15];
[username setTextAlignment:UITextAlignmentLeft];
[username setText:[d valueForKey:#"UserName"]];
[cell addSubview:username];
[username release];
UILabel *Password = [[UILabel alloc]initWithFrame:CGRectMake(11, 25, 280, 30)];
Password.textColor =DARK_VIEW;
Password.font=[UIFont fontWithName:#"arial" size:12];
[Password setTextAlignment:UITextAlignmentLeft];
[Password setText:[d valueForKey:#"Password"]];
[cell addSubview:Password];
[Password release];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SMutableDictionary *d = (NSMutableDictionary *) [arr objectAtIndex:indexPath.row]
NSString *forNExtViewString =[d valueForKey:#"EmployeID"];
objSectonView =[[cntrSecodviewcontroller alloc]initWithNibName:#"cntrSecodviewcontroller" bundle:nil];
[self.navigationController pushViewController:objSectonView animated:YES];
}
You forgot to set the tableView delegate and datasource. Your datasource also looks like it contains a collection of NSDictionaries. In your cellForRow you have to correctly extract the values from the dictionary
- (void)viewDidLoad
{
[super viewDidLoad];
UITableView* tableView = [[UITableView alloc] initWithFrame:self.view.bounds];
tableView.delegate = self;
tableView.dataSource = self;
[self.view addSubview:tableView];
}
Like Nitin Gohel pointed out
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil)
{
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
}
cell.textLabel.text = [[arr objectAtIndex:indexPath.row] valueForKey:#"UserName"];
return cell;
}
Just make sure about the following things :
Values are retained in the array
Reload your TableView after the objects are added to array.
i.e [tableView reloadData];
And Just replace your method with this one.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil)
{
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
}
//Over here just print the value of your array , to cross check whether the values are retained in the Array
NSLog(#"%#",[arr objectAtIndex:indexPath.row]);
NSString *tempstring= [[arr objectAtIndex:indexPath.row] valueForKey:#"UserName"];
cell.textLabel.text= tempstring;
return cell;
}
This would definitely bring the solution of your problem.
Check this and confirm your delegates, that might be the reason of not getting tableview called.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
tablView = [[UITableView alloc]initWithFrame:CGRectMake(10, 10, 300, 460)];
tablView.delegate = self;
tablView.dataSource = self;
[self.view addSubview:tablView];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath*)indexPath
{
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
UITableViewCell * cell = [tablView
dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
if(cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier] autorelease];
}
UILabel *lbl5 = [[UILabel alloc]initWithFrame:CGRectMake(30, 5, 250, 50);];
UILabel *lbl6 = [[UILabel alloc]initWithFrame:CGRectMake(30, 60, 250, 50)];
lbl1.text = [arrayName objectAtIndex:i];
lbl2.text = [arrayAddress objectAtIndex:i];
NSString *tempstring=[arr1 objectAtIndex:indexPath.row];
NSString *tempstring=[arr2 objectAtIndex:indexPath.row];
[cell addSubview:lbl1];
[cell addSubview:lbl2];
// cell.textLabel.text= tempstring;
return cell;
}
You are accessing array at indexPath, and this array contain dictionary, so first get array and take it in dictionary and access it with key value
cell.textLabel.text = [[arr objectAtIndex:indexPath.row] objectForKey:#"UserName"];
Your mutable array has elements of dictionary type. so while updating the text in table cell try to grab dictionary from array based on your indexPath.row and then objectForKey: for whichever key you want to use. see code below
you should try to use
cell.textLabel.text = [[yourMutableArr objectAtIndex:indexPath.row] valueForKey:#"UserName"];
cell.detailTextLabel.text = [[yourMutableArr objectAtIndex:indexPath.row] valueForKey:#"Password"];
and you can use the default separater of table cells.

Compare indexpath Of Cell with uiButton Is This Possible?

I have a Uibutton in one class and Uitable in different Class...
Now i want to compare IndexPAth(Particular cell Position) with Uibutton Of Different class...
Actually i want to print Different different value on particular cell Which I am Fetching from Different Different Uibutton`s Methods from another class....
Here is My code....
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath == btn1){ // This is the Line What i want , i am trying this but dont go inside the condition..
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(200, 5, 290, 60)];
lbl.backgroundColor = [UIColor clearColor];
//lbl.editable = NO;
lbl.font = [UIFont fontWithName:#"Helvetica-Bold" size:25];
// txtView1.text= textviewstring;
// txtView1.text = #"Personal";
if([fetchFormArray222 count]<1){
lbl.text=#"";
}
else{
lbl.text = [fetchFormArray222 objectAtIndex:0];
}
// [txtView1 setDelegate:self];
lbl.textColor = [UIColor blackColor];
lbl.textAlignment = UITextAlignmentLeft;
[[cell contentView] addSubview:lbl];
}
else {
}
Check the apple documentation of UITableView.
Have you tried to use the button in the other class to perform a new fetch in the class you're focusing on that loads fetctFormArray222 and then reload the UITableView?

Xcode UITableView Row not highlighted when selected

I have a working table view on my iphone app, and am implementing a second view using navigationController.
But when I try to select a cell on the initial view, it does not respond i.e. no highlighting in blue, no selection.
Can anyone suggest what I might have missed, or what is responsible for actually selecting the cell when the user taps it?
OK thanks for your suggestions - still no luck. here is my code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
[cell setSelectionStyle: UITableViewCellSelectionStyleBlue];
UIView *selectionView = [[[UIView alloc] init] autorelease];
selectionView.backgroundColor =[UIColor redColor];
cell.selectedBackgroundView = selectionView;
}
// format text
cell.textLabel.font = [UIFont fontWithName:#"Arial" size:12];
cell.textLabel.text = [tableArray objectAtIndex:indexPath.row];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//NSUInteger row = indexPath.row;
//[DetailView selectRowAtIndexPath:indexPath animated:YES];
//UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath.row];
//[cell setSelectionStyle: UITableViewCellSelectionStyleBlue];
DetailView *detailView = [[DetailView alloc] initWithNibName:#"DetailView" bundle:nil];
[self.navigationController pushViewController:detailView animated:YES];
[DetailView release];
}
May be you have done this line of code in cellForRowatIndexPath::
cell.selectionStyle = UITableViewCellSelectionStyleNone;
If yes, then replace it with either of these:
cell.selectionStyle = UITableViewCellSelectionStyleGray;
or
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
Without looking at your code I would say you have to add this line in your cellForRowAtIndexPath delegate method.
[cell setSelectionStyle:UITableViewCellSelectionStyleBlue];
And also you have to implement this delegate method which gets called when you tap on cell of UITableView..
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}

i want to display cells in table view with some gap between them

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [topics count];
}
- (UITableViewCell *) getCellContentView:(NSString *)cellIdentifier {
CGRect cellFrame = CGRectMake(0,0,320,45);
UITableViewCell *cell = [[[UITableViewCell alloc] initWithFrame:cellFrame reuseIdentifier:cellIdentifier] autorelease];
CGRect bgFrame = CGRectMake(10,5,300,35);
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"list_bg_up.png"]];
backgroundView.frame = bgFrame;
[cell addSubview:backgroundView];
UILabel *txtLabel = [[UILabel alloc] initWithFrame:CGRectMake(20,10,250,25)];
txtLabel.textColor=[UIColor whiteColor];
txtLabel.backgroundColor = [UIColor clearColor];
txtLabel.tag = 1;
[cell addSubview:txtLabel];
return cell;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell;
static NSString *kDisplayCell_ID = #"DisplayCellID";
//cell = [self.tableView dequeueReusableCellWithIdentifier:kDisplayCell_ID];
cell = [tableView dequeueReusableCellWithIdentifier:kDisplayCell_ID];
if(cell == nil) {
cell = [self getCellContentView:kDisplayCell_ID];
}
aTopic = [topics objectAtIndex:indexPath.row];
UILabel *txtLabel = (UILabel *)[cell viewWithTag:1];
txtLabel.text = aTopic.description;
return cell;
}
-(CGFloat)tableView:(UITableView *)tbView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 45;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
ResourcesViewController *resViewController = [[ResourcesViewController alloc] initWithNibName:#"ResourcesViewController" bundle:[NSBundle mainBundle]];
resViewController.aTopic = [topics objectAtIndex:indexPath.row];
[self.navigationController pushViewController:resViewController animated:YES];
[resViewController release];
}
if i want to change space between cells wat i hav to change in this code ....
now with this code i am able to display cells with some gap but i didnt understand how the gap defined...
If you're talking about vertical height of the cells, change this code:
-(CGFloat)tableView:(UITableView *)tbView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 45;
}
If you're talking about the horizontal space between data in the cell, you need to modify the CGRects here:
CGRect cellFrame = CGRectMake(0,0,320,45);
UITableViewCell *cell = [[[UITableViewCell alloc] initWithFrame:cellFrame reuseIdentifier:cellIdentifier] autorelease];
CGRect bgFrame = CGRectMake(10,5,300,35);
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"list_bg_up.png"]];
backgroundView.frame = bgFrame;
[cell addSubview:backgroundView];
UILabel *txtLabel = [[UILabel alloc] initWithFrame:CGRectMake(20,10,250,25)];
Next time be a little more clear about what you're asking. And don't forget to accept answers to questions you ask. Cheers
I think maybe you need a look at this SO question:

Accordion table cell - How to dynamically expand/contract uitableviewcell?

I am trying create an accordion type of uitableviewcell that, when the user selects the cell, it expands to display a detailed info view inline similar to how the digg app works. I initially tried replacing the current tablecell with a customcell in cellForRowAtIndex, however the animation looks a bit choppy as you can see the cell being replaced and overall the effect doesn't work too well.
If you look at the digg app and others who have done this it seems that they aren't replacing the current cell but instead perhaps adding a subview to the cell? The original cell however doesn't seem to animate at all and only the new view accordions into the table.
Does anyone have any ideas how to accomplish a similar effect?
I have made some progress using neha's method below and while the cell is animating the correct way it is wreaking havoc with the other cells in the table. What I have done is subclassed UITableViewCell with a custom class which contains an instance of a UIView which actually draws the view which I then add to the table cell's contentview.
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
if (selected) {
[self expandCell];
}
}
-(void)expandCell {
self.contentView.frame = CGRectMake(0.0, 0.0, self.contentView.bounds.size.width, 110);
}
Here are all the table delegate methods I am using:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if (isSearching && indexPath.row == selectedIndex) {
static NSString *CellIdentifier = #"SearchCell";
CustomTableCell *cell = (CustomTableCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[cell setCustomTitle:[timeZoneNames objectAtIndex:indexPath.row] detail:[timeZoneNames objectAtIndex:indexPath.row]];
UILabel *theText = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 10.0, cell.contentView.bounds.size.width -20, 22.0)];
theText.text = #"Title Text";
[cell.contentView addSubview:theText];
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10.0, 10 + 46.0, cell.contentView.bounds.size.width - 20, 40.0)];
textField.borderStyle = UITextBorderStyleLine;
[cell.contentView addSubview:textField];
UILabel *testLabel = [[UILabel alloc] initWithFrame:CGRectMake(5.0, 88.0, cell.contentView.bounds.size.width - 20, 22.0)];
testLabel.text = [NSString stringWithFormat:#"Some text here"];
[cell.contentView addSubview:testLabel];
[theText release];
[textField release];
[testLabel release];
return cell;
} else {
static NSString *CellIdentifier = #"Cell";
CustomTableCell *cell = (CustomTableCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[cell setCustomTitle:[timeZoneNames objectAtIndex:indexPath.row] detail:[timeZoneNames objectAtIndex:indexPath.row]];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:NO];
selectedIndex = indexPath.row;
isSearching = YES;
[tableView beginUpdates];
[tableView endUpdates];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (isSearching && indexPath.row == selectedIndex) {
return 110;
}
return rowHeight;
}
It seems now that the cell is expanding but not actually being refreshed so the labels, and textfield aren't being shown. They do however show up when I scroll the cell off and on the screen.
Any ideas?
The Apple way to do is quite simple.
First, you'll need to save the selected indexPath row:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.selectedRowIndex = [indexPath retain];
[tableView beginUpdates];
[tableView endUpdates];
}
I'll explain the begin/end updated part later.
Then, when you have the currently selected index, you can tell the tableView that it should give that row more space.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
//check if the index actually exists
if(selectedRowIndex && indexPath.row == selectedRowIndex.row) {
return 100;
}
return 44;
}
This will return height 100 for the selected cell.
Now we can go back to the begin/end updates. That block triggers the reload of all tableView geometry. Moreover, that block is animated, which eventually gives the impressions of the row expanding.
Pawel's beginUpdates/endUpdates trick is good, and I often use it. But in this case you simply need to reload the rows that are changing state, ensuring that you correctly reload them with the desired cell type, and that you return the correct new cell height.
Here is a complete working implementation of what I think you're trying to accomplish:
.h:
#import <UIKit/UIKit.h>
#interface ExpandingTableViewController : UITableViewController
{
}
#property (retain) NSIndexPath* selectedIndexPath;
#end
.m:
#implementation ExpandingTableViewController
#synthesize selectedIndexPath;
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return 10;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier1 = #"Cell1";
static NSString *CellIdentifier2 = #"Cell2";
UITableViewCell *cell;
NSIndexPath* indexPathSelected = self.selectedIndexPath;
if ( nil == indexPathSelected || [indexPathSelected compare: indexPath] != NSOrderedSame )
{
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1] autorelease];
}
cell.textLabel.text = [NSString stringWithFormat: #"cell %d", indexPath.row];
}
else
{
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier2] autorelease];
}
cell.textLabel.text = [NSString stringWithFormat: #"cell %d", indexPath.row];
cell.detailTextLabel.text = [NSString stringWithFormat: #"(expanded!)", indexPath.row];
}
return cell;
}
#pragma mark -
#pragma mark Table view delegate
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ( self.selectedIndexPath != nil && [self.selectedIndexPath compare: indexPath] == NSOrderedSame )
{
return tableView.rowHeight * 2;
}
return tableView.rowHeight;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray* toReload = [NSArray arrayWithObjects: indexPath, self.selectedIndexPath, nil];
self.selectedIndexPath = indexPath;
[tableView reloadRowsAtIndexPaths: toReload withRowAnimation: UITableViewRowAnimationMiddle];
}

If you don't want to reload the cell (you want to keep your existing cell and just change the size, and likely add/remove some subviews), then simply do the beginUpdates/endUpdates trick in didSelectRowAtIndexPath:, and call some method on your cell to incite the layout change. beginUpdates/endUpdates will prompt the tableView to re-query the heights for each cell - so be sure to return the correct value.
Create a class that subclasses UITableviewcell in your project. Create this class' nib and set its parent to be the class in your project with tableview and override its -
(void)setSelected:(BOOL)selected animated:(BOOL)animated
Write methods contractCell() and expandCell() in this class, and provide the height of the cells you want in expandCell method. Call this methods appropriately based on some flags set to identify wheather the cell is in expanded state or contracted state. Use your tableview's
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
method to handle selection of cells.
Replace your cellForRowAtIndexPath function with this one.
