I have a bit of static text I set with a value of: @"record Added"

want it to disappear after 3 seconds and I thought the easiest way
would be to just change the value to: @"" with a timer.
Currently I have this: [self setStringValue:complete withObject:@""
afterDelay:3.0];
Which doesn't seem to work and has the following warning:
'mainController' may not respond to '-
setStringValue:withObject:afterDelay:'
What am I doing wrong please and what should my code really be?
Well the compiler is telling you exactly what is wrong;
mainController doesn't respond to the -
setStringValue:withObject:afterDelay: message. Instead, you need to
do:
[self performSelector:@selector(setStringValue:) withObject:@""
afterDelay:3.0];
Actually, since the original receiver of the message is "complete", it
(not "self") should still be the receiver of the
performSelector:withObject:afterDelay:.
Like so:
[complete performSelector:@selector(setStringValue:) withObject:@""
afterDelay:3.0];
Cheers,
Ken
