    If you have loaded the data into an NSArray you can't change it: NSArrays are immutable. If you have loaded it to a NSMutableArray you can use the well documented removeObjectAtIndex:. Obviously this will only alter your in-memory copy of the data: it will have no effect on the plist file. If the file is within your application bundle you can't save to that.
