Minimum Requirements

SDK Size: 3.8MB
Average Memory Footprint: <10MB

The Vrtcal SDK fully supports iOS 10.0 and higher. Additionally, iOS 9.0 is supported, but deprecated and ads will not be shown.

The Vrtcal SDK uses the arm64 Device Capability which excludes:

• iPhone 5
• 1st Generation iPad Mini(2012)
• Other Apple Devices released prior to Autumn 2012

Installation

Installation via CocoaPods

CocoaPods is a dependency manager for iOS projects which automates and simplifies installation of 3rd-party libraries. You can install CocoaPods with the following command:

$ gem install cocoapods

To integrate Vrtcal SDK using MoPub as you primary SDK using CocoaPods, add Vrtcal-MoPub-Adapters or Vrtcal-AdMob-Adapters to your Podfile. Example PodFiles:

platform :ios, '9.0'
project 'MyProject.xcodeproj'
target 'MyTarget'
pod 'Vrtcal-AdMob-Adapters'

platform :ios, '9.0'
project 'MyProject.xcodeproj'
target 'MyTarget'
pod 'Vrtcal-MoPub-Adapters'

Then run the following command:

$ pod install

You will still have to perform the steps “Modify AppDelegate” and “Update Info.plist” from the manual installation steps.

Manual Installation

Download the SDK

Download our SDK from https://ui.vrtcal.com/sdk_downloads/VRTCALSDK_iOS_2_1_1.zip and unzip the file. The resulting vrtcal-sdk directory will have the following files:

Add VrtcalSDK.framework to your App

1. Download VrtcalSDK.framework and add it to your projects Frameworks Folder (If the folder doesn't exist, create it).

2. Verify that VrtcalSDK.framework is in Frameworks, Libraries, and Embedded Content and that Embed & Sign is selected.



3. Verify that under Project->Targets(your app)>Build Settings->Search Paths a path in the Framework Search Paths section points to the Frameworks directory:

Modify AppDelegate for AdMob(same as GAM) Adapter

In your AppDelegate, import VrtcalSDK and Initialize the SDK with your application ID:

Swift:

VrtcalSDK.initializeSdk(withAppId:1, sdkDelegate:self)

Objective-C:

[VrtcalSDK initializeSdkWithAppId:appId sdkDelegate:self];

If you do not wish to be alerted to the success or failure of Vrtcal SDK’s initialization, you may set sdkDelegate to nil.

Update info.plist

Though the Vrtcal SDK communicates entirely with https some ad content still uses http. In order for these ads to load correctly and to increase revenue, please add an exception to App Transport Security settings:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

The VRTCAL SDK supports MRAID 3.0 ads which, if the user has interacted with the ad, may ask via a popup to perform an action such as write to the photo album, add a contact to the user’s contact list, or create a calendar event:

<key>NSCalendarsUsageDescription</key>
<string>Some ad content may access calendar</string>
<key>NSContactsUsageDescription</key>
<string>Some ad content may access contacts list</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Some ad content may access photo library</string>

The VRTCAL SDK will not ask the user for access to Location Services but if it is available to the application, it will use location data to enrich ad requests:

<key>NSLocationWhenInUseUsageDescription</key>
<string>Please allow access to Location Services</string>

Showing Banner Ads

On the ViewController from which you will be serving ads, import the VrtcalSDK and implement VRTBannerDelegate:

Objective-C:

- (void)vrtBannerAdLoaded:(nonnull VRTBanner *)vrtBanner withAdSize:(CGSize)adSize {
}

- (void)vrtBannerAdFailedToLoad:(nonnull VRTBanner *)vrtcalBanner error:(nonnull NSError *)error {
}

- (void)vrtBannerAdClicked:(nonnull VRTBanner *)vrtcalBanner {
}

- (void)vrtBannerAdWillLeaveApplication:(nonnull VRTBanner *)vrtcalBanner {
}

- (void)vrtBannerWillPresentModal:(nonnull VRTBanner *)vrtBanner ofType:(VRTModalType)modalType {
}

- (void)vrtBannerDidPresentModal:(nonnull VRTBanner *)vrtBanner ofType:(VRTModalType)modalType {
}

- (void)vrtBannerWillDismissModal:(nonnull VRTBanner *)vrtBanner ofType:(VRTModalType)modalType {
}

- (void)vrtBannerDidDismissModal:(nonnull VRTBanner *)vrtBanner ofType:(VRTModalType)modalType {
}

- (void)vrtBannerVideoStarted:(nonnull VRTBanner *)vrtBanner {
}

- (void)vrtBannerVideoCompleted:(nonnull VRTBanner *)vrtBanner {

- (nonnull UIViewController *)vrtViewControllerForModalPresentation {
    return self;
}

Swift:

  func vrtBannerAdLoaded(_ vrtcalBanner:VRTBanner, withAdSize adSize: CGSize) {

  }
    
  func vrtBannerAdFailedToLoad(_ vrtcalBanner: VRTBanner, error: Error) {

  }
  
  func vrtBannerAdClicked(_ vrtcalBanner: VRTBanner) {

  }
  
  func vrtBannerWillPresentModal(_ vrtcalBanner: VRTBanner, of modalType: VRTModalType) {

  }
  
  func vrtBannerDidPresentModal(_ vrtcalBanner: VRTBanner, of modalType: VRTModalType) {

  }
  
  func vrtBannerWillDismissModal(_ vrtcalBanner: VRTBanner, of modalType: VRTModalType) {

  }
  
  func vrtBannerDidDismissModal(_ vrtcalBanner: VRTBanner, of modalType: VRTModalType) {

  }
  
  func vrtBannerAdWillLeaveApplication(_ vrtcalBanner: VRTBanner) {

  }
  
  func vrtBannerVideoStarted(_ vrtBanner: VRTBanner) {

  }
  
  func vrtBannerVideoCompleted(_ vrtBanner: VRTBanner) {

  }
  
  func vrtViewControllerForModalPresentation() -> UIViewController {
      return self
  }

1. Do one of the following:

1. Manually instantiate a VRTBanner:

   let vrtBanner = VRTBanner(frame: CGRect(x:0, y:0, width:320, height:50))

2. 1. Create one in a Storyboard by adding a UIView Object and setting the custom class of the object to VRTBanner:

   

   2. Create an IBOutlet for the banner:

   @IBOutlet var vrtBanner: VRTBanner!

2. Set the banner’s adDelegate and implement all delegate methods. Call loadAd() with the zoneId of your ad. Note: If you need help setting up an ad unit check out the relevant docs here.

  // Ads
    vrtBanner.adDelegate = self
    vrtBanner.loadAd(1)
  

3. If the banner successfully loads it will call vrtBannerAdLoaded-withAdSize and automatically display. If it fails, it will call vrtBannerAdFailedToLoad error. Banner refresh rates are controlled server-side and may be adjusted by editing your Vrtcal line item.

Showing Interstitial Ads

1. On the ViewController from which you will be serving ads import the VrtcalSDK and implement VRTInterstitialDelegate:
Objective-C:

  - (void)vrtInterstitialAdClicked:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialAdDidDismiss:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialAdDidShow:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialAdFailedToLoad:(VRTInterstitial *)vrtInterstitial error:(NSError *)error {

  }

  - (void)vrtInterstitialAdFailedToShow:(VRTInterstitial *)vrtInterstitial error:(NSError *)error {

  }

  - (void)vrtInterstitialAdLoaded:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialAdWillDismiss:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialAdWillLeaveApplication:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialAdWillShow:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialVideoCompleted:(VRTInterstitial *)vrtInterstitial {

  }

  - (void)vrtInterstitialVideoStarted:(VRTInterstitial *)vrtInterstitial {

  }

  - (UIViewController*)vrtViewControllerForModalPresentation {
    return self;
  }
     
  

Swift:

  func vrtInterstitialAdLoaded(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialAdFailed(toLoad vrtInterstitial: VRTInterstitial, error: Error) {

  }
  
  func vrtInterstitialAdWillShow(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialAdDidShow(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialAdFailed(toShow vrtInterstitial: VRTInterstitial, error: Error) {

  }
  
  func vrtInterstitialAdClicked(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialAdWillLeaveApplication(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialAdWillDismiss(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialAdDidDismiss(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialVideoStarted(_ vrtInterstitial: VRTInterstitial) {

  }
  
  func vrtInterstitialVideoCompleted(_ vrtInterstitial: VRTInterstitial) {

  }

  func vrtViewControllerForModalPresentation() -> UIViewController {
      return self
  }

2. Instantiate a VRTInterstitial and set the adDelegate. Then call loadAd() with the zoneId of your ad unit as an argument:

    
  let vrtInterstitial = VRTInterstitial()
  override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    self.vrtInterstitial.adDelegate = self
    self.vrtIntertitial.loadAd(10024)
  }
    
  

3. If the Interstitial successfully loads, vrtInterstitialAdLoaded will be called, at which point showAd may be called on the interstitial object to display the ad. If the interstitial fails to load, vrtInterstitialAdFailed will be called.

    func vrtInterstitialAdLoaded(_ vrtInterstitial: VRTInterstitial) {
      vrtInterstitial.showAd()
    }

    func vrtInterstitialAdFailed(toLoad vrtInterstitial: VRTInterstitial, error: Error) {
      print("error: \(error)")
    }
 

Important Notes

Ad Lifecycle

You can only call loadAd() on VRTBanner or VRTInterstitial once for each instance. If you want to load another ad you must create a new instance. In the case of banners you should remove the old VRTBanner from the view hierarchy and replace it with the new one. This, however, does not apply if you use our SDK's banner refresh mechanism.

GDPR

We support IAB's GDPR framework. Follow IAB's instructions on how to save the user's GDPR settings in IOS NSUserDefaults and/or to integrate their SDK in your project. You should set GDPR settings before you invoke any VRTCAL SDK API functionality.

Ad Mediation

The Vrtcal iOS SDK supports mediation as both a Primary SDK (the one doing the mediating) and a Secondary SDK (one being mediated, typically MoPub or Google SDKs). Several mediation adapters are included in the “MediationAdapters” directory of your download:

Mediating Vrtcal SDK through MoPub

NOTE: If you are using Mopub version 5.12 or below, you must use the adapter contents under the folder named 'Vrtcal-MoPub-Adapters-1.0.5.1' instead of the folder named 'Vrtcal-MoPub-Adapters'.

1. If you have not done so already, ask your VRTCAL account manager to create your Vrtcal ad unit. Ask for integration parameters and note the App ID and the newly created Zone Id.

2. Create an ad unit & line item on http://mopub.com. Set the following values on the line item:

Banner Example:

3. Please note that it can take about 5 minutes for changes to ad units & line items to take effect.

4. Either integrate the adapter via cocoapods (see above) or copy the following 4 files from your Vrtcal_Mobile_SDK download into your app’s Xcode Project:

5. Your MoPub ad unit should now be capable of displaying VRTCAL ads.

Mediating Vrtcal SDK through Google SDKs [AdMob/GAM]

1. If you have not done so already, ask your VRTCAL account manager to create your Vrtcal ad unit. Ask for integration parameters and note the App ID and the newly created Zone Id.

2. Create an ad unit & line item on https://apps.admob.com. Under the Map Ad Units section, set the following values:<

Banner Example:

3. Please note that it can take about 5 minutes for changes to ad units & line items to take effect.

4. Either integrate the adapter via cocoapods (see above) or copy the following 4 files from your Vrtcal_Mobile_SDK download into your app’s Xcode Project:

3. If you have not done so already, ask your VRTCAL account manager to create your VRTCAL ad unit. Ask for integration parameters and write down the App ID and Zone ID.

4. Create a Custom Network on applovin.com. Set the Network Type to SDK and the iOS Adapter Class name to VRTMediationAdapter.
   

5. Create an ad unit and select your new Vrtcal Custom Network. Fill the App ID field with your Vrtcal App ID and the Placement ID with your Vrtcal Zone ID.
   
6. Your AppLovin ad unit should now be capable of displaying VRTCAL ads.

Mediating Vrtcal SDK through IronSource

1. Add the following line to your project's Podfile:
   pop "Vrtcal-IronSource-Adapters"
   
   From the command line, run:
   pod install

2. Alternatively, if you prefer not to use Cocoapods, put all the files from the Vrtcal-IronSource-Adapters of your Vrtcal SDK download into your project.
3. If you have not done so already, ask your VRTCAL account manager to create your VRTCAL ad unit. Ask for integration parameters and write down the App ID and Zone ID.

4. In your IronSource account, go to SDK Networks and select Manage Networks, then click on "Custom Adapter".
   

5. At the "Custom Adapter" prompt, enter "VRTCAL" for the network key.
   
6. Select "Interstitial" and enter your App ID and the Zone ID you will be mediating with.
   
7. Under "SDK Networks", select your app and make sure that "Intersitital" is set to "Active".
   
8. Your IronSource ad unit should now be capable of displaying VRTCAL ads.

Mediating Vrtcal SDK through Fyber-Fairbid

1. Add the following line to your project's Podfile:
   pop "Vrtcal-Fyber-FairBid-Adapters"
   
   From the command line, run:
   pod install

2. Alternatively, if you prefer not to use Cocoapods, put all the files from the Vrtcal-Fyber-FairBid-Adapters of your Vrtcal SDK download into your project.
3. If you have not done so already, ask your VRTCAL account manager to create your VRTCAL ad unit. Ask for integration parameters and write down the App ID and Zone ID.

4. Follow these instructions to create an ad unit on your Fyber FairBid account and configure mediation:
   https://developer.fyber.com/hc/en-us/articles/360009974718-Setting-Up-FairBid

FAQ

Q: Where can I reach out for help?

A: Reach out to us at support@vrtcal.com

Q: How do I increase the likelihood that my ad gets filled?

A: There are many factors that affect advertiser interest and spend. Aside from the content type/category of your application, there things that you can do to build and maintain advertiser interest, such as (1) if you are able to include location data; (2) set a refresh rate of 30 seconds or greater; (3) include as much device data that is available; and (4) make sure the ad unit location is a good placement with content.

Q: Why are some ads showing up as blank?

A: This could be for many reasons, it may be an ad that was configured incorrectly by the advertiser, it could be that the ad is using the non-secure HTTP protocol which requires extra configuration to allow ads that use HTTP, or it could we something that need to look into email us at support@vrtcal.com

Q: Does VRTCAL have adapters for other SDKs besides MoPub?

A: The current SDK only includes a MoPub at the moment, but we have others on the way.

Q: Where do I create an Ad Unit?

A: Once you are a registered user on vrtcal.com navigate to the SDK Management section click on the "Add New Ad Unit" button.
