Answer 1

This can be more easily done by having a single section and displaying all of your information in that section formatted.

To do that, return 1 in numberOfComponentsInPickerView (or omit that method as I believe the default is 1). In titleForRow, create a string that has the information from both of the keys.

NSObject *companyId = [[self.jsonresultarr objectAtIndex:row] objectForKey:@"Company_Id"];
NSObject *companyName = [[self.jsonresultarr objectAtIndex:row] objectForKey:@"Company_name"];
return [NSString stringWithFormat:@"%@ %@", companyId, companyName, nil];
