Im trying to add parse data into my table array and i get'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0] any help on how to resolve this would be appreciated.

tableData2 = [NSArray arrayWithObjects:t21, t22, t23, t24, t25, nil];

It means that you array is empty and you try to access the index 1 which is not able to get it. You better debug yourself.
And if you want to do the introspection on the NSString, you only need to use the length method to check. It will return false if your NSString is either nil or empty.

I am trying to create an expandable table view, however when I click on one of the cells I load a .xib file to format the subviews, however when I click the cell again the .xib format remains and messes with the view of the cells. Is there a better way to make the expandable table view?
Code:
- (BOOL)tableView:(UITableView *)tableView canCollapseSection:(NSInteger)section
{
return YES;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 28;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if ([self tableView:tableView canCollapseSection:section])
{
if ([expandedSections containsIndex:section])
{
return [ticketList count];
}
return 1; // only top row showing
}
// Return the number of rows in the section.
return 1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 72;
}
Load the xib here:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {

Update
The main cell is a list of items and the expanding cell is suppose to be tickets from a sql database. I use a xib file to format the tickets
but when I collapse the cell which contains the items, this image remains and covers up the item cells
For creating expandable table view on clicking of UITableViewCell simply add a new cell in existing UITableView
[self.tableview insertRowsAtIndexPath:indexPath
withRowAnimation:UITableViewRowAnimationAutomatic];
am getting the following error, cannot figure it out where it is. Please help me to find out the issue. TIA

NSArray do not respond to length, but count.
Most probably in value you expect a NSString, but there is an array instead.
Something is wrong when you set the value.
Might be you are expecting something different and it having other type of values.May be you are expecting NSString and it is giving any other type.
Youc can use id data type so that it can be helpful. This solved for me.Hope for you also.
This:
[myDict objectForKey:[keys objectAtIndex:i]];
is returning an NSArray, not a NSString.
What I want to do here is set it so that if top3ArrayForSection.count-1 < 1, set the _results bool value of that respective section to NO, and so on. What's happening instead, is that _results is set to NO or YES for the entire table overall, so that I end up with a result like this:
When only the "xperia Z3 compact unlocked" section should say "no items found etc." because it has no cells, the other sections cells shouldn't.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSDictionary *currentSectionDictionary = _matchCenterArray[section];
NSArray *top3ArrayForSection = currentSectionDictionary[#"Top 3"];
if (top3ArrayForSection.count-1 < 1){
_results = NO;
_rowCount = 1;
}
else if(top3ArrayForSection.count-1 >= 1){
_results = YES;
_rowCount = top3ArrayForSection.count-1;
}
return _rowCount;
}

if (_results == NO) {

}
else if (_results == YES) {

cell.textLabel.text = _matchCenterArray[indexPath.section][#"Top 3"][indexPath.row+1][#"Title"];
cell.textLabel.font = [UIFont boldSystemFontOfSize:14];
// price of the item
cell.detailTextLabel.text = [NSString stringWithFormat:#"$%#", _matchCenterArray[indexPath.section][#"Top 3"][indexPath.row+1][#"Price"]];

Your instance variable _results is one-dimensional. You could replace it with an NSArray and store the values individually, or you could change the logic in your code as such:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSDictionary *currentSectionDictionary = _matchCenterArray[section];
NSArray *top3ArrayForSection = currentSectionDictionary[#"Top 3"];
return (top3ArrayForSection.count-1 < 1) ? 1 : top3ArrayForSection.count-1;
}
// Cell layout
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Initialize cell
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
// if no cell could be dequeued create a new one
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
// No cell seperators = clean design
tableView.separatorColor = [UIColor clearColor];
NSDictionary *currentSectionDictionary = _matchCenterArray[indexPath.section];
NSArray *top3ArrayForSection = currentSectionDictionary[#"Top 3"];
if (top3ArrayForSection.count-1 < 1) {
// title of the item
cell.textLabel.text = #"No items found, but we'll keep a lookout for you!";
cell.textLabel.font = [UIFont boldSystemFontOfSize:12];
}
else {
// title of the item
cell.textLabel.text = _matchCenterArray[indexPath.section][#"Top 3"][indexPath.row+1][#"Title"];
cell.textLabel.font = [UIFont boldSystemFontOfSize:14];
// price of the item
cell.detailTextLabel.text = [NSString stringWithFormat:#"$%#", _matchCenterArray[indexPath.section][#"Top 3"][indexPath.row+1][#"Price"]];
cell.detailTextLabel.textColor = [UIColor colorWithRed:0/255.0f green:127/255.0f blue:31/255.0f alpha:1.0f];
// image of the item

I have a bug.
I want to display a UIImageView on cells at special indexPath.row, but these UIImageView repeat while I scroll.
Exemple: I display my UIImageView on a cell indexPath.row == 0, if I scroll down, I see my UIImageView on the cell at indexPath.row == 8.
Here is my code:
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [self getCellContentView:CellIdentifier];
}
UILabel *lblTemp1 = (UILabel *)[cell viewWithTag:1];
UIImageView *imgRead = (UIImageView *)[cell viewWithTag:6];
[cell.contentView insertSubview:imgRead aboveSubview:lblTemp1];
contentDictio = [dict objectAtIndex:indexPath.row];
lblTemp1.text = [contentDictio objectForKey:#"title"];
NSArray *paths_id = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath_id = ([paths_id count] > 0) ? [paths_id objectAtIndex:0] : nil;
NSString *path_id = [basePath_id stringByAppendingPathComponent:#"id.plist"];
NSMutableArray *mut_array_id = [[NSArray arrayWithContentsOfFile:path_id] mutableCopy];
NSMutableDictionary *c0 = [[NSMutableDictionary alloc] init];
NSString *idPlistData = [contentDictio objectForKey:#"id"];
for(c0 in mut_array_id) {
if([[c0 objectForKey:#"id"] isEqualToString:idPlistData]) {
[imgRead setImage:[UIImage imageNamed:#"read"]];
}
else {
}
}
}
return cell;
}
- (UITableViewCell *) getCellContentView:(NSString *)cellIdentifier {
CGRect Label1Frame = CGRectMake(kTableCellSmallMargin*2 + 60, kTableCellSmallMargin, 240, 25);
UILabel *lblTemp;
UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:cellIdentifier] autorelease];
//Initialize Label with tag 1.
lblTemp = [[UILabel alloc] initWithFrame:Label1Frame];
lblTemp.tag = 1;
lblTemp.backgroundColor = [UIColor clearColor];
[lblTemp setFont: [UIFont fontWithName:#"HelveticaNeue-CondensedBold" size:15.0]];
[cell.contentView addSubview:lblTemp];
[lblTemp release];
UIImageView *read=[[UIImageView alloc] initWithFrame:CGRectMake(kTableCellSmallMargin, kTableCellSmallMargin, 60, 60)];
read.backgroundColor=[UIColor clearColor];
read.tag = 6;
[cell.contentView addSubview:read];
[read release];
return cell;
}
Thanks...
The cell is cached, so you have to clear it when you want no image, like this:
BOOL found = NO;
for(c0 in mut_array_id) {
if([[c0 objectForKey:#"id"] isEqualToString:idPlistData]) {
[imgRead setImage:[UIImage imageNamed:#"read"]];
found = YES;
}
else {
}
}
if (!found)
{
[imgRead setImage:nil];
}
I created at least 10 cells with each UITextField on it, for registration page. When I insert the words on the textfield in the first cell, and when I scrolled the tableView, the textfield which is in another cell show up the word that I just typed.
Below is my code. The textField data which I input is looping, which is caused by dequeueReusableCellWithIdentifier... How can I solve this problem? Thank you very much.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"RCell";
RegisterCell *cell = (RegisterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

}
[cell.contentView addSubview:valTxtField];
[valTxtField release];
}
else if(indexPath.section == 1){

NSString *mainLabel = [NSString stringWithFormat:#"%#", [rowData objectForKey:#"regisLbl"]];
cell.registerLabel.text = mainLabel;
cell.registerTextField.enabled = NO;
}
else if(indexPath.section == 2){
if(indexPath.row == 0){
NSDictionary *rowData = [self.regisLabel objectAtIndex:[indexPath row]+11];

An easy way is to just remove all subviews from the cells contentView before you add subviews, example:
for (UIView *subview in [cell.contentView subviews])
[subview removeFromSuperview];
A more efficient way would be to do all the creation of cells inside the if (cell == nil) statement, but that depends on how many cells you have in the table.
The right implementation is to move the creation of any view whithin if (cell == nil)
Like so:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"RCell";
RegisterCell *cell = (RegisterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UITextField *valTxtField;
if (cell == nil)
{
cell = [[[RegisterCell alloc] initWithFrame:CGRectMake(0, 0, 280, 44) reuseIdentifier:CellIdentifier] autorelease];
if(indexPath.section == 0){
valTxtField = [[UITextField alloc] initWithFrame:CGRectMake(120, 5, 180, 30)];
valTxtField.font = [UIFont fontWithName:#"Futura-CondensedExtraBold" size:18.0];
valTxtField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
valTxtField.delegate = self;
valTxtField.returnKeyType = UIReturnKeyDone;
valTxtField.autocorrectionType = UITextAutocorrectionTypeNo;
valTxtField.autocapitalizationType = UITextAutocapitalizationTypeNone;
valTxtField.tag = 100;
[cell.contentView addSubview:valTxtField];
[valTxtField release];
}
}
valTxtField = (UITextField *)[cell.contentView viewWithTag:100];
if(indexPath.section == 0){
NSDictionary *rowData = [self.regisLabel objectAtIndex:[indexPath row]];
NSString *mainLabel = [NSString stringWithFormat:#"%#", [rowData objectForKey:#"regisLbl"]];
cell.registerLabel.text = mainLabel;
if(indexPath.row == 0)
{
valTxtField.text = #"";
emailTxtFld = valTxtField; //emailTxtFld is global variable
