MREC

View-Based Ad Type

MREC is a view-based ad format that behaves differently from other Appodeal ad types. Unlike interstitial or rewarded video ads, MREC ads are displayed as views that need to be manually added to your view hierarchy.

MREC is a 300x250 banner. This type can be useful if the application interface has a large free area for placing a banner.

You can use our demo app as a reference project.

Check If Ad Is Loaded

Important

For MREC ads, you must use the mrec.isReady property to check if an ad is loaded and ready to display.

Do NOT use Appodeal.isLoaded(.MREC) or Appodeal.canShow(.MREC) as they are unreliable for MREC and will return false even when an ad is loaded and ready to show.

Swift

// MREC view - CORRECT way to check if loaded
mrec.isReady 

// ❌ INCORRECT - These methods are unreliable for MREC:
// Appodeal.isLoaded(.MREC)  // Will return false even when loaded
// Appodeal.canShow(.MREC)   // Will return false even when loaded

Objective-C

// MREC view - CORRECT way to check if loaded
mrec.isReady;

// ❌ INCORRECT - These methods are unreliable for MREC:
// [Appodeal isLoaded:AppodealAdTypeMREC];  // Will return false even when loaded
// [Appodeal canShow:AppodealAdTypeMREC];   // Will return false even when loaded

---

Display

AppodealMRECView is a subclass of AppodealBannerView. The size of AppodealMRECView is 300x250.

MREC ads are refreshed every 15 seconds automatically by default. To display MREC, you need to call the following code:

Swift

import UIKit
import Appodeal

class YourViewController: UIViewController, AppodealBannerViewDelegate {

  override func viewDidLoad () {
    super.viewDidLoad()
    // required: init ad banner
    let mrecView: AppodealMRECView = AppodealMRECView()
    mrecView.usesSmartSizing = false
    mrecView.rootViewController = self

    // optional: set delegate
    mrecView.delegate = self

    // required: add banner to superview and call -loadAd to start banner loading
    self.view.addSubview(mrecView)
    mrecView.loadAd()
  }

  // optional: implement any of AppodealBannerViewDelegate methods
  func bannerViewDidLoadAd(_ bannerView: APDBannerView, isPrecache precache: Bool) {
     NSLog("bannerView was loaded")       
  }

  func bannerView(_ bannerView: APDBannerView, didFailToLoadAdWithError error: Error) {
     NSLog("bannerView failed to load");        
  }

  func bannerViewDidInteract(_ bannerView: APDBannerView) {
     NSLog("bannerView was clicked")
  }

  func bannerViewDidShow(_ bannerView: APDBannerView) {
     NSLog("bannerView was shown")
  }

  func bannerViewExpired(_ bannerView: APDBannerView) {
     NSLog("bannerView did expire and could not be shown")
  }
}

Objective-C

#import "YourViewController.h"
#import <Appodeal/Appodeal.h>

interface YourViewController () <AppodealBannerViewDelegate>
@end

@implementation YourViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  
  // required: init ad banner
  AppodealMRECView *mrecView= [[AppodealMRECView alloc] initWithRootViewController:self];
  
  // optional: set delegate
  mrecView.delegate = self;
  
  // required: add banner to superview and call loadAd to start banner loading
  [self.view addSubview:mrecView];
  [mrecView loadAd];
}

// optional: implement any of AppodealBannerViewDelegate methods
- (void)bannerViewDidLoadAd:(APDBannerView *)bannerView {
  NSLog(@"Banner %@ did load!", bannerView);
}

- (void)bannerViewDidInteract:(APDBannerView *)bannerView {
  NSLog(@"Banner %@ did interact", bannerView);
}

- (void)bannerView:(APDBannerView *)bannerView didFailToLoadAdWithError:(NSError *)error {
  NSLog(@"Banner %@ did fail with error: %@", bannerView, error);
}

- (void)bannerViewDidRefresh:(APDBannerView *)bannerView {
   NSLog(@"Banner %@ did refresh ", bannerView);
}

@end

Manual Caching

MREC does not support autocache.

To cache MREC use:

Swift

// MREC view
mrec.loadAd()

Objective-C

// MREC view
[mrec loadAd];

---

Read more on manual caching in our FAQ.

Callbacks

Callbacks are used to track different events of an ad's lifecycle, e.g., when a MREC has been successfully loaded or is about to appear. To get them, you need to set the delegate as follows:

Swift

//set delegate
Appodeal.setBannerDelegate(self)

Objective-C

//set delegate
[Appodeal setBannerDelegate:self];

---

Usually, the class that implements banners is also the delegate class. That's why the delegate property can be set to self.

Now you can use the following callbacs methods:

Swift

// banner was loaded (precache flag shows if the loaded ad is precache)
func bannerDidLoadAdIsPrecache(_ precache: Bool) {}
// banner was shown
func bannerDidShow() {} 
// banner failed to load
func bannerDidFailToLoadAd() {}
// banner was clicked 
func bannerDidClick() {} 
// banner did expire and could not be shown
func bannerDidExpired() {} 

Objective-C

- (void)bannerDidLoadAdIsPrecache:(BOOL)precache {
    // banner was loaded (precache flag shows if the loaded ad is precache)
}

- (void)bannerDidShow {
    // banner was shown
}

- (void)bannerDidFailToLoadAd {
    // banner failed to load
}

- (void)bannerDidClick {
    // banner was clicked
}

- (void)bannerDidExpired { 
    // banner did expire and could not be shown
} 

---

note

All callbacks are called on the main thread.

Placements

Appodeal SDK allows you to tag each impression with different placement. To be able to use placements, you need to create them in Appodeal Dashboard. Read more about placements.

Swift

Appodeal.showAd(.MREC, forPlacement: placement, rootViewController: self)

Objective-C

[Appodeal showAd:AppodealShowStyleMREC forPlacement:placement rootViewController:self];

---

Important for MREC

Do not use Appodeal.canShow(.MREC, forPlacement:) to check if an ad can be shown for a placement. This method is unreliable for MREC and will return false even when an ad is ready to display.

Instead, use mrec.isReady to check if the MREC view has a loaded ad before displaying it.

If the loaded ad can't be shown in a specific placement, nothing will be shown. If auto caching is enabled, the SDK will start to cache another ad, which can affect display rate.

---

You can configure your impression logic for each placement.

If you have no placements or call Appodeal.show with a placement that does not exist, the impression will be tagged with 'default' placement with corresponding settings applied.

Important!

Placement settings affect ONLY ad presentation, not loading or caching.

Get Predicted eCPM

This method returns the expected eCPM for the cached ad. The amount is calculated based on historical data for the current ad unit.

Swift

Appodeal.predictedEcpm(for: .MREC)

Objective-C

[Appodeal predictedEcpmForAdType: AppodealAdTypeMREC]; 

---

Check If Ad is Initialized

Swift

Appodeal.isInitialized(for: .MREC)

Objective-C

[Appodeal isInitalizedForAdType: AppodealAdTypeMREC];

---

Returns true if MREC was initialized.

Check if Autocache Is Enabled For Ad

MREC does not support autocache.

Hide

MREC is a view. To hide MREC, remove it from superView

Swift

// MREC view
mrec.removeFromSuperview()   

Objective-C

// MREC view
[mrec removeFromSuperview];

Check Viewability

You can always check in logs if show was tracked and your ad is visible.

You will see the following log if show was tracked successfully.

[Appodeal *.*.*] [debug] [impression] Impression <APDImpression: 0x600002953b10> succesfully tracked
