NSArray count not working - iphone

Question

So I have a UITableView, and I populate the tableview with data from a .plist. This has been working fine for me until today, when I tried to do the same and I can't get the numberOfRowsInSection, method to work. Here is my code:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if...
else if (segmentOptions == exchange){
NSArray *array = [NSArray arrayWithArray:[exchangeDictionary objectForKey:[listOfExchanges objectAtIndex:section]]];
return [array count];
}
//Else
return contentArray.count;
}
So in that code, everytime I run it, the code crashs. But, I use basiacally the same code to set the tableview text and that works fine:
- (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...
else if (segmentOptions == exchange) {
NSArray *array = [NSArray arrayWithArray:[exchangeDictionary objectForKey:[listOfExchanges objectAtIndex:indexPath.section]]];
cell.textLabel.text = [array objectAtIndex:indexPath.row];
}
return cell;
}
And that code works fine, which is why I'm so confused. When I set the number of rows to return to a specific number, and run the rest of the code, everything works fine. So I'm really lost. Thands in advance
UPDATE
I tried it with the proper count notation, return [array count];, and I still get the same crash and the same console output.

Answer 1

First, count is not a property so you should not be using dot syntax to access it.
I would suggest changing your code so that you are not accessing the count method like a property.
Second,
Test to see if your array is nil and that it is even an array.
Third,
Post the actual complete stack trace.

Answer 2

Break it down and debug, if console message is not being helpful. It helps sometimes, specially when it's late. i.e.
// NSArray *array = [NSArray arrayWithArray:[exchangeDictionary objectForKey:[listOfExchanges objectAtIndex:section]]];
NSLog(#"%d", section);
id objAtIndex = [listOfExchanges objectAtIndex:section];
NSLog(#"%#", listOfExchanges);
NSLog(#"%#", objAtIndex);
id objForKey = [exchangeDictionary objectForKey:objAtIndex];
NSLog(#"%#", exchangeDictionary);
NSLog(#"%#", objForKey);

Answer 3

Try this:
[array count]
count is not a property, it is a method you run on the array.
