For all those who learn Objective C with GNUstep…
Mostly you will learn using For-Each statement , for manipulating NSMutableArray.
But with GNUstep, it is not possible.
The for each statement looks like this,
1 for(NSObject *st in myMutableArrayObject) {
2 NSLog(@"%@",[st myMethodDefined]);
3 }
Here is how we can do it without For-Each statement,
1 for(i=0; i< [myMutableArrayObject count]; i++) {
2 NSLog(@"%@",[[myMutableArrayObject objectAtIndex: i] myMethodDefined]);
3 }
Here, we are using a method predefined called count which returns the number of objects in the MutableArray Object
and then another method objectAtIndex which iterates the objects at the interval from 0 to (count – 1).
