TableView选择在iPhone应用程序中崩溃

Question

I have table view with records in. The problem is that when we click on cell according to series like 1, 2, 3, then it works fine, but if we select 2 directly then it crashes. Here is my code.

My tableView has multiple sections having data in sections.

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

  {

static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

    cell.selectionStyle=UITableViewCellSelectionStyleGray;
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;


}



if (indexPath.section==0) 

{
    cell.textLabel.font=[UIFont fontWithName:@"Helvetical Bold" size:14];
    cell.textLabel.textColor=[UIColor blackColor];
    ObjectData*coffeeObj=[subCategoryArray objectAtIndex:indexPath.row];
    cell.textLabel.text=coffeeObj.subCategoryTitle;
    return cell;

}


else if (indexPath.section==1) 

{
    cell.textLabel.font=[UIFont fontWithName:@"Helvetical Bold" size:14];
    cell.textLabel.textColor=[UIColor blackColor];
    ObjectData*coffeeObj=[subCategoryArrayOne objectAtIndex:indexPath.row];
    cell.textLabel.text=coffeeObj.subCategoryTitle;
    return cell;

}




else {


    cell.textLabel.font=[UIFont fontWithName:@"Helvetical Bold" size:14];
    cell.textLabel.textColor=[UIColor blackColor];
    ObjectData*coffeeObj=[subCategoryArrayTwo objectAtIndex:indexPath.row];
    cell.textLabel.text=coffeeObj.subCategoryTitle;
    return cell;



}}




    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {



NSString*title;

if (indexPath.section==0) {




    ObjectData*coffeeObj=[subCategoryArray objectAtIndex:indexPath.row];


    NSString*subCatID =coffeeObj.subCategoryID;


    NSArray *tempArray =[[DataController staticVersion] startParsing:[NSString stringWithFormat:@"http://www.celeritas-solutions.com/pah_brd_v1/productivo/getDetailData.php?subCatID=%@",subCatID]];

    for (int i = 0; i<[tempArray count]; i++) {

        id *item = [tempArray objectAtIndex:i];
        NSDictionary *dict = (NSDictionary *) item;
        ObjectData *theObject =[[ObjectData alloc] init];

Answer 1

In didSelectRowAtIndexpath

addObject: adds the object to array but the reference is same,and you are releasing it at the end of loop Remove

[theObject release];
 theObject=nil;

add/use

    ObjectData *theObject =[[[ObjectData alloc] init]autorelease];

EDIT

The error says you are trying to access a value from an array which is not having that number of values in it.It is a range exception
