Question

I am trying to make an app in which i use the Grouped Table view .In that I am creating the sections in which the first letter comes from an array and it is doing perfectly.
the code is below

sections=[[NSMutableArray alloc] init];

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

 NSString *s=[[PdfNames objectAtIndex:i] substringToIndex:1];        

    NSPredicate *p=[NSPredicate predicateWithFormat:@"letter like '%@'",s];

    NSArray *check=[sections filteredArrayUsingPredicate:p];


    if([check count]<1)

    {
         dict=[[[NSMutableDictionary alloc] init] autorelease];
        [dict setValue:s forKey:@"letter"];
        [sections addObject:dict];

    }


}

But now i am not able to get that hoe can i get the names of pdf from array which belongs to their secion Or starts with that alphabet.

Answer 1

You are creating an array sections which is of course empty. You then create an array check based on sections. It will therefore also be empty. [check count] will always be zero. No NSDictionary is going to be created.

Clear?
