Loop through NSArray objectAtIndex

NSInteger *count = [monLessonArrayA count]; for (i = 0; i < count; i++) { arrayVar = [monLessonArrayA objectAtIndex:i]; }

I get an error saying i is undeclared, how can I set the objectAtIndex to i so I can loop through increasing it each time?

Thanks.

You can also use fast enumeration, which is actually faster:

for (id someObject in monLessonArrayA) {
    // Do stuff
}

You just forgot to declare i (and its data type) before using it in the loop:

for (int i = 0; i < count; i++) {

Because your i is undeclared. 

for (int i = 0; i < count; i++)

Also, you don't need the * for your NSInteger. 

NSInteger count = [monLessonArrayA count];
