How do I loop through or alternate this switch for my iOS game button?

I currently have a button in my game that calls a different ad every time its tapped. Here is the code. 

- (IBAction)VideoAds:(id)sender{

int random = arc4random_uniform(2);

switch (random)
{
    case 0:
    {
        VungleSDK* sdk = [VungleSDK sharedSDK];
        [sdk playAd:self];

        NSLog(@"Case 0 Displayed - Vungle");
    }
        break;
    case 1:
        [AdColony playVideoAdForZone:@"APP_ID" withDelegate:nil];
        NSLog(@"Case 1 Displayed - AdColony");

        break;

   }

}

Everything works fine and when I tap the button I get either Case 0 or Case 1 randomly. I want to change that so that get each case in order or for them to alternate back and forth. I do not want random. I know it's probably just a simple 10 second fix, but I've spent over an hour searching Google and Stackoverflow trying to figure out how to do it. Thanks for any help!

Try this :

iHoldCaseNo will be golbal variable which hold the iHoldCaseNo case no to be execute.

- (IBAction)VideoAds:(id)sender{

int random = iHoldCaseNo;

switch (random)
{
    case 0:
    {
        VungleSDK* sdk = [VungleSDK sharedSDK];
        [sdk playAd:self];
        iHoldCaseNo=1;
        NSLog(@"Case 0 Displayed - Vungle");
    }
        break;
    case 1:
        [AdColony playVideoAdForZone:@"APP_ID" withDelegate:nil];
        NSLog(@"Case 1 Displayed - AdColony");
        iHoldCaseNo=0;
        break;

   }

}

Or alternate way is to set the sender i.e button tag as 0 or 1 and according to that handle the switch case.

//For setting the tag use.
sender.tag=1 in case 0 and sender.tag=1 in case 1 
//to get random no,
int random = sender.tag;
