iOS playing with variables and text views

[blueblaze4444]

I'm a bit of a newb here. So given the code shown below, I have a UITextView called scheduleView which changes from day to day - I'm using the variable "day" which represents the day of the year (This is meant to display a school's daily rotation/schedule - which are all stored in strings which I didn't include below). But let's say that I wanted to scroll through this text view - as in, sliding/pulling the textview right or left to see schedules for the days to come or previous days. I'm guessing that somehow I would have to use an action which adds or subtracts 1 from "day" each time it is performed. My question is: what kind of action would I use to do this?

NSDate *today = [[NSDate alloc] init];
    NSCalendar *cal = [NSCalendar currentCalendar];
    NSUInteger day = [cal ordinalityOfUnit:NSDayCalendarUnit
                                    inUnit:NSYearCalendarUnit
                                   forDate:today];
    
    if (day == 341) {
        scheduleView.text = R2;
    }
    else if (day == 339){
        scheduleView.text = LS;
    }
    else if (day == 342) {
        scheduleView.text = B1;
    }
    else if (day == 343) {
        scheduleView.text = B2;
    }
    else if (day == 345) {
        scheduleView.text = R1;
    }
    else if (day == 346) {
        scheduleView.text = R2;
    }
    else if (day == 347) {
        scheduleView.text = R3;
    }
    else if (day == 348) {
        scheduleView.text = R1;
    }
    else if (day == 349) {
        scheduleView.text = MS;
    }
    
    else {
        scheduleView.text = @"No School Today!";
    }
    
}

You might want to consider putting the schedules in different views and presenting them in something like a scroll view. You will have a much easier time detecting that the user scrolled and updating the content.

Check out the UIScrollView docs, its delegate protocol and the PhotoScroller sample project.

Should give you some ideas!
