UITableView content height issue causing application crash - iphone

Question

I have two UITableViews in my view which shows same contents(verses of bible) but in diffrent language,top tableview shows english and bottom-table shows hindi.everything works fine,but some chapters the verse loads the data in uitableview the application crashes,the error is in this area
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGSize textSize = [[delegate.allSelectedVerseEnglish objectAtIndex:indexPath.row] sizeWithFont:[UIFont fontWithName:#"Georgia" size:18.0 ] constrainedToSize:CGSizeMake(280.0f,MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
return textSize.height +20;
CGSize textSizehindi = [[tempArray objectAtIndex:indexPath.row] sizeWithFont:[UIFont fontWithName:#"testfont" size:18.0 ] constrainedToSize:CGSizeMake(280.0f,MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
return textSizehindi.height +20;
}
and also after playing too much time in uitableview ,it cause the slow down of scrolling of UITableViewCells.And there is no smooth scrolling occours.Is there any eroor in above code which i get error while loading some chapters.
Thanks in advance.
EDIT:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
readCell *cell = (readCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"readCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.textLabel.numberOfLines = 0;
}
if(tableView == table)
{
UIView *myBackView = [[UIView alloc] initWithFrame:cell.frame];
myBackView.backgroundColor = [UIColor colorWithRed:250.0 green:248.0 blue:192.0 alpha:1.0];
[myBackView setBackgroundColor:[UIColor colorWithRed:1 green:1 blue:0.75 alpha:1]];
cell.selectedBackgroundView = myBackView;
[myBackView release];
table.backgroundColor = [UIColor clearColor];
table.separatorColor = [UIColor clearColor];
cell.chapterAndVerse.text = [NSString stringWithFormat:#"%d",indexPath.row+1];
cell.chapterAndVerse.font = [UIFont fontWithName:#"Georgia" size:17.0];
cell.chapterAndVerse.frame=CGRectMake(0, 10, 30.0, 20.0);
cell.textLabel.text = [NSString stringWithFormat:#" %#",[delegate.allSelectedVerseEnglish objectAtIndex:indexPath.row]];
cell.textLabel.font = [UIFont fontWithName:#"Georgia" size:18];

}
else if(tableView == tab)

cell.textLabel.font = [UIFont fontWithName:#"testfont" size:18];
cell.backgroundColor = [UIColor clearColor];
}
return cell;
}
EDIT2
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (tableView == table) {
return [delegate.allSelectedVerseEnglish count];
}
else if (tableView == tab )
{
return [tempArray count];
}
}

Answer 1

first do one thing. before use of your both array, NSLog the both array before reloading table. And check both array have same number of objects. it may be a reason of crashing.

Answer 2

in the above code first add the conditions for returning the text size for english and hindi verse. because currently you are always returning the text size of first english verse.The main problem you are facing is not in your above code.The problem should be on your another table view delegate call:- CellForRowAtIndexPath.
Can you paste your CellForRowAtIndexPath delegate call here so that i can give you more idea.

Answer 3

2nd part of your heightForRowAtIndexPath method is never called. It allways returning return textSize.height +20; Most possible way to crash is null pointer delegate.allSelectedVerseEnglish or unexisting font.
