One Array - Multiple sections – NSIndexPath

Tarun Kumar153927-Jul-2015

I have one big array with many values. I've sorted out the sections but I can't seem to get the indexpath right.

Basically, what I'm trying to do, is that if the previous section has 50 rows, the next indexpath.row should be 51->. The one after that should be 60-> and so fourth.

NSLog(@"current indexpath.row: %ld",(long)indexPath.row); 
NSLog(@"current section: %ld",(long)indexPath.section); 
for (int i = indexPath.section; i == indexPath.section; i++) { 
            NSLog(@"number of rows: %ld",(long)[self tableView:tableView
 numberOfRowsInSection: indexPath.section]); 
            NSLog(@"in section: %ld",(long)indexPath.section); 
 
    if (i++) { 
        // add previous number of rows plus current 
        int previousRows = [self tableView:tableView numberOfRowsInSection:
 indexPath.section*2]; 
        NSLog(@"now indexpath: %ld",(long)previousRows+indexPath.row);
    } 
}

 

I hope I've made my question clear enough for you to understand.

NSIndexPath doesn't work this way. NSIndexPath starts from 0 for every section.

 

If I understand correctly, you want to know the global index value to access the array. For that case, I have been using this little method:

- (int)getGlobalRowFor:(int)row at:(int)section { 
    if(section == 0) { 
        return row; 
    } else { 
        int count = 0; 
        for(int i = 0; i < section; i++) { 
            // This is where you put your own numbers for section counts. 
            // This is my model, yours could be different. 
            count += [[[self.sections objectAtIndex:i] objectForKey:@"sectionCount"]
 intValue];
        }
        return count + row; 
    } 
}
