But I want the number of objects to be part of a text string ("The
number of students is: <the value>"). Thus I put this code into
myDocument.m:
-(NSString *) numberOfStudents
{
return [NSString stringWithFormat:@"The number of students is: %@",
[theStudentArrayController
valueForKeyPath:@"[EMAIL PROTECTED]"]];
}
No error during compilation or run-time, but value in the text label
is not updated when the array is changed.
For a simple thing like this you might also use a "Pattern Binding":
