objectAtIndex:indexPath.row method always causes exception in IOS
- by kalkin
Hi I always seem to get exception when I use objectAtInded method to retrieve NSString from an array. I am reading data from a dictionary which is in the "PropertyList.plist" file.My code is
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"PropertyList"
ofType:@"plist"];
names = [[NSDictionary alloc]
initWithContentsOfFile:path];
keys = [[[names allKeys] sortedArrayUsingSelector:
@selector(compare:)] retain];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSUInteger section = [indexPath section];
NSUInteger row = [indexPath row];
NSString *key = [keys objectAtIndex:section];
NSArray *nameSection = [names objectForKey:key];
static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SectionsTableIdentifier];
if(cell == nil)
{
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SectionsTableIdentifier] autorelease];
}
cell.textLabel.text = [nameSection objectAtIndex:row];
return cell;
}
The exception happens on the method "cellForRowAtIndexPath" in the line
cell.textLabel.text = [nameSection objectAtIndex:row];
The error message is
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary objectAtIndex:]: unrecognized selector sent to instance 0x6832440
Where ever I use "[nameSection objectAtIndex:row];" type of statement it always get exception.
