how to get a2[0]=Norman , a2[1]=stanley???
Trying this
NSArray *listItems = [list componentsSeparatedByString:@", "];
[a2 addObject:list];
NSLog(@"array o %@", [a2 objectAtIndex:0]);
When you create a mutable array you have to add objects to the array. You can't set the mutable array equal to a normal array (its returned by componentsSeparatedByString:)
NSString *list = @"Norman, Stanley, Fletcher"; NSMutableArray *a2 = [[NSMutableArray alloc] init]; [a2 addObjectsFromArray:[list componentsSeparatedByString:@", "]]; NSLog(@"array is %@",a2); NSLog(@"array o %@",[a2 objectAtIndex:0]);
