Question

I’m creating a quiz app, and I was wondering instead of using multiple if statements, I could make an algorithm that uses an int to alternate between UIViews when you click a UIButton. With multiple if statements the code would look something like this:

IBAction NextQuestion; {

    Question++; //QUESTION IS THE int FOR THE ALGORITHM.

    if (Question==2) {
        self.view = PlayView2; //PlayView2 is the UIView I'm switching to.
        }

    if (Question==3) {
        self.view = PlayView3; //PlayView3 is the UIView I'm then switching to after the next object/UIButton is pressed.
        }        

and so on…

The IBAction is connected to multiple UIButtons to change the view. The goal is I want to change the UIView algorithmically instead of multiple if statements Thanks for your help!

Answer 1

myViewsArray = [[NSArray alloc] initWithObjects: PlayView2, PlayView3, ..., PlayViewN, nil];

    -(UIView*) nextView {
       if( Question < [myViewsArray count] )
           return [myViewsArray objectAtIndex: Question++];

       return nil;
    }
