Question

I’m new to ios, trying to do something like this

self.dataArray = [dictionary valueForKey:@"LIST"];

{
  "List": [
    {
      "FULLNAME": "FirstName, LastName",
      "ID": "281"
    }
  ]
}

I want to swap the value which is in ‘FULLNAME’, that is I want it to be LastName, FirstName

I tried various methods but it would not work. Can someone tell me how to accomplish this?

Thank you

Assuming you know how to do the dictionary manipulation, here’s one way to swap the elements in the string:

NSString* name = @"Firstname, Lastname";
// Remove the space after comma (not necessary if you know the name will always
// have a space after comma, then just split on ', '.
NSString* normalizedName = [name stringByReplacingOccurrencesOfString:@", " withString:@","];
// Split the string on ','.
NSArray* nameParts = [normalizedName componentsSeparatedByString:@","];
// Reverse the array
NSArray* reverseNameParts = [[nameParts reverseObjectEnumerator] allObjects];
// Join the array with ', '
NSString* revname = [reverseNameParts componentsJoinedByString:@", "];
NSLog(@"Reversed name parts: %@", revname);
