isEqualTo is if you want to compare values. "if (mystr==@"test")" will
never return true, because the pointer to mystr is different than the
pointer to @"test". So, you'd use "if ([mystr isEqualTo:@"test")" to
compare the values.
To check to see if the two pointers are pointing to the same object, if
(sender==okButton) is both fastest and most reliable.
