I am trying to make a method in which the data source for my NATableView is cleared, but I cannot figure out how to do this anywhere.

Here is the code I am using to send an array called final to my table view. 

// I want to clear it here before filling it again.  
for (int i = 0; i < [final count]; i++) {
    [myArrayController addObject: [NSMutableDictionary dictionaryWithObjectsAndKeys:final[i], @"File Name", nil]];
}

Any help would be great!

  • Clear like remove all the objects from the array controller? – CodaFi Feb 20 '13 at 18:55
  • Yup exactly, just looking for the command, I think I have the syntax. – Andrew Doig Feb 20 '13 at 18:58

  • Got the answer from the link above. NSRange range = NSMakeRange(0, [[myArrayController arrangedObjects] count]); [myArrayController removeObjectsAtArrangedObjectIndexes:[NSIndexSet indexSetWithIndexesInRange:range]]; Thanks. – Andrew Doig Feb 20 '13 at 19:06

If you are using an NSMutableArray and myArrayController is your mutable array you want to call 

[myArrayController removeAllObjects];

before you enter the for-loop.
