# iOS Native Ads Integration

• In the native advertising, SDK is providing advertising content ( parts ), rather than to provide a compleated ad layout.
• Therefore it is possible to delivery to advertisment in the original design, whatever you want to title, description text, icons etc.
• Ads SDK processes Ad impressions , Ad clicks of tracking.

# Preparation

Preparation Integration for Native Ads, please look at [Install iOS SDK] below :

Install iOS SDK

# Class and Protocol

Class for iOS Native Ad

• GNNativeAdRequest : Class to Request Native Ad with asynchronous
• GNNativeAd : Class to provide information of Native Ad
• GNNativeAdRequestDelegate : Protocol to receive loading event of Native Ad

# Request Native Ad

0. Add GNAdSDK.framework to your project.
   Install iOS SDK

1. Import GNNativeAdRequest.h, GNNativeAd.h

   #import <GNAdSDK/GNNativeAdRequest.h>
   #import <GNAdSDK/GNNativeAd.h>
   

   1
   2
   

2. Use GNNativeAdRequestDelegate Protocol

   @interface TableViewController () <GNNativeAdRequestDelegate>
   {
   }
   

   1
   2
   3
   

3. Declare GNNativeAdRequest variable

   GNNativeAdRequest *_nativeAdRequest;
   

   1
   

4. Initialize GNNativeAdRequest instance

   _nativeAdRequest = [[GNNativeAdRequest sharedManager] initWithID:@"YOUR_ZONE_ID"];

   • multiAd Example for using Initialize API

    _nativeAdRequest = [[GNNativeAdRequest sharedManager] initWithID:@"YOUR_ZONE_ID_1,YOUR_ZONE_ID_2,...."];
   

   1
   

5. Set up GNNativeAdRequest delegate Notice result of native ad loading event through the delegate. Set the instance of GNNativeAdRequestDelegate to this delegate.

   _nativeAdRequest.delegate = self;
   

   1
   

6. Load Native Ad

• single Ad.

  [_nativeAdRequest loadAds];
  

  1
  
• multi Ad.

  [_nativeAdRequest multiLoadAds];
  

  1
  

7. Implement GNNativeAdRequestDelegate Protocol Implement callback function of GNNativeAdRequestDelegate to receive the result of native ad loading event.

   - (void)nativeAdRequestDidReceiveAds:(NSArray*)nativeAds;
   - (void)nativeAdRequest:(GNNativeAdRequest *)request didFailToReceiveAdsWithError:(NSError *)error;
   

   1
   2
   

Received native ads is return by an array of GNNativeAd arguments. You can use the zoneID field of GNNativeAd to determine which ad has been received. The number of elements in the array GNNativeAd : - one : Set up one ZONE_ID when Initialize GNNativeAdRequest

8. Set up delegate to nil, when instance of GNNativeAdRequest is released.

   - (void)dealloc
   {
       _nativeAdRequest.delegate = nil;
   }

  #import <GNAdSDK/GNNativeAdRequest.h>
  #import <GNAdSDK/GNNativeAd.h>
  
  @interface TableViewController () <GNNativeAdRequestDelegate>
  {
      GNNativeAdRequest *_nativeAdRequest;
  }
  @property (nonatomic, strong) NSMutableArray *cellDataList;
  @end
  
  @implementation TableViewController
  
  - (void)viewDidLoad {
      [super viewDidLoad];
  
      _nativeAdRequest = [[GNNativeAdRequest sharedManager] initWithID:@"YOUR_ZONE_ID"];
      _nativeAdRequest.delegate = self;
      [_nativeAdRequest multiLoadAds];
  }
  
  - (void)nativeAdRequestDidReceiveAds:(NSArray*)nativeAds
  {
      for (GNNativeAd *nativeAd in nativeAds) {
          // You can identify the GNNativeAd by using the zoneID field of GNNativeAd.
          //if ([nativeAd.zoneID isEqualToString:@"YOUR_ZONE_ID"]) {
          //    [_cellDataList addObject:nativeAd];
          //}
          [_cellDataList addObject:nativeAd];
      }
  }
  
  - (void)nativeAdRequest:(GNNativeAdRequest *)request didFailToReceiveAdsWithError:(NSError *)error
  {
      NSLog(@"TableViewController: didFailToReceiveAdsWithError : %@.", [error localizedDescription]);

• The type of information data reffer to GNNativeAd.h class

• If the information data (NSString type) is not set , it will be nil

• If the information data (int, double type) is not set , it will be 0

  Name	Type	Data
  zoneID	NSString	ID for zone in Geniee
  advertiser	NSString	Name of client
  title	NSString	Title of feed advertisement
  description	NSString	description of advertisment
  cta	NSString	text for call to action

• You can refer to GNNativeAd.h class to know opt-out information.

• Get opt-out information from SDK You can use instance of GNNativeAd.h nativeAd to access opt-out information

NString *optout_text = nativeAd.optout_text;
NString *optout_image_url = nativeAd.optout_image_url;
NString *optout_url = nativeAd.optout_url;

• Fire click for Opt-out When User clicks to open Opt-out page for setting information, you will open optout_url from your Application

Note: Sometime optout_url can be empty (It means this Ad not support to setup optout information)

• Image of UITableViewController

  

# Impression report for Native Ad

• You need to report the imoression of advertisment When the Native Ad is rendered.

• It is not possible to report for imoression reported again.

• You need to request Native Ad again to display new advertismsent.

  [nativeAd trackingImpressionWithView:cell];

# Click tracking for Native Ad

• When the native ad is clicked, it will start the landing page of advertising in an external browser.

  [nativeAd trackingClick];

• e.g.: implementation of UITableViewController

  -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
      TableViewCell *cell = (TableViewCell*)[tableView cellForRowAtIndexPath:indexPath];
      if (cell.nativeAd != nil) {

# Video Native Ad

By adding option to allow movies with Native Ad setting information from the management screen, you can acquire video native advertisement.

# Classes and Protocol

Video native ads use the following video player classes and protocols.

• GNSNativeVideoPlayerView Class for providing video Native Player View.
• GNSNativeVideoPlayerDelegate Protocol for receiving video native player's event notification.

# Data acquisition for movie native

When viewing movie native ads, please use hasVideoContent() from GNNativeAd instance to make motion picture judgment.

 - (void)nativeAdRequestDidReceiveAds:(NSArray*)nativeAds
 {
     for (GNNativeAd *nativeAd in nativeAds) {
         if ([nativeAd hasVideoContent]) {
             //video implements
         }
     }
 }

# Native video implementation method

1. Import GNSNativeVideoPlayerView header file and add Delegate.

   #import <GNAdSDK/GNNativeAdRequest.h>
   #import <GNAdSDK/GNNativeAd.h>
   #import <GNAdSDK/GNSNativeVideoPlayerView.h>
   @interface ViewController <GNSNativeVideoPlayerDelegate>

2. Generate instances of GNSNativeVideoPlayerView and add views.

• Example of generation from GNNativeAd.

  GNSNativeVideoPlayerView videoView = [nativeAd getVideoView]; // GNNativeAd nativeAd
  [containerView addSubview:videoView]

• Example of generation on the application side.

  GNSNativeVideoPlayerView videoView = [[GNSNativeVideoPlayerView alloc] initWithFrame:rect]; // CGRect rect
  [containerView addSubview:videoView]

3. Implement the method of GNSNativeVideoPlayerDelegate, Receive video native player's event.

   @required
   // Sent when an video ad request succeeded.
   - (void)onVideoReceiveSetting:(GNSVideoPlayerView*)view;
   @optional
   // Sent when an video ad request failed.
   - (void)onVideoFailWithError:(GNSVideoPlayerView*)view error:(NSError *)error;
   
   // Sent when an video ad play started.
   - (void)onVideoStartPlaying:(GNSVideoPlayerView*)view;
   
   // Sent when an video ad okay completed.
   - (void)onVideoPlayComplete:(GNSVideoPlayerView*)view;

5. Set GNNativeAd as an argument and make a video request.

• If you generate GNSNativeVideoPlayerView from NativeAd, request it below.

  [videoView load];

6. If you can prepare the movie, it will judge the movie preparation completion and start the movie.

   - (void)onVideoReceiveSetting:(GNSVideoPlayerView*)view {
       // Video preparation completion determination
       if ([videoView isReady]) {
           // Video playback start
           [videoView show];

   // Release of videoView
   [videoView remove];
   // Replay (Cue playback. If used, available after show).
   [videoView replay];
   // Set the mute
   [videoView setMuted:YES]
   // get the mute
   [videoView getMuted]; // true or false, default true
   // Set the visibility of mute button
   [videoView setVisibilityMuteButton:YES];
   // Get the visibility of mute button
   [videoView getVisibilityMuteButton]; // true or false, default true
   // Set the visibility of progress bar
   [videoView setVisibilityProgressbar:YES];
   // Get the visibility of progress bar
   [videoView getVisibilityProgressbar]; // true or false, default true
   // Set the visibility of replay button
   [videoView setVisibilityReplayButton:YES];
   // Get the visibility of replay button
   [videoView getVisibilityReplayButton]; // true or false default true
   // Get the width of video size
   int width = [videoView getMediaFileWidth]; // 1600
   // Get the Height of video size
   int height = [videoView getMediaFileHeight]; // 900
   // Get the total time of seconds of video
   float aspect = [videoView getMediaFileAspect]; // 1.777..
   // Get the duration of seconds of video
   float duration = [videoView getDuration]; // 30.000
   // Get the current play time of seconds
   float playTime = [videoView getCurrentposition]; // 15.000
   // playing judgment
   [videoView isPlaying]; // true or false

# How to continue to play videos even when the terminal rotates

Please use the following IF to change the size of GNSNativeVideoPlayerView according to the size at terminal rotation.

   -(void)viewDidAppear:(BOOL)animated
   {
       // Rotation notification registration.
       [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
       NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
       [nc addObserver:self selector:@selector(didChangedOrientation:) name:UIDeviceOrientationDidChangeNotification object:nil];
   }

   - (void)viewDidDisappear:(BOOL)animated
   {
       // Release of rotation notification.
       NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
       [nc removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];
       [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
   }

- (void)didChangedOrientation:(NSNotification *)notification
{
   if (videoView) {
       CGRect frame = CGRectMake(0, 0, width, height)
       [videoView setFrame:frame];
   }
}

# About stopping automatic playback of movies

As for movie native, the movie area stops playing according to the ratio of the terminal content display area as follows. Playback is stopped at the timing when the ratio changes due to scrolling or when switching to another application.

• Movie playing condition ... When the moving picture area is 50% or more of the terminal contents display area
• Movie stop condition ... When the moving image area is less than 50% of the terminal contents display area

# About multiple videos

• For movie display, we recommend one memory per screen due to memory load.
• It is recommended to release unnecessary video instances.

# Regulation of video advertisement

About video advertisement optout-url display Please be sure to go. If there are reasons such as not wanting to display due to the characteristics of the application Please consult Geniee representative.

# Integration Ads SDK in Swift

It is neccesary to write an import statetment in header files to Objective-C bridging header file, when it utilized iOS SDK (Objective-C) class from Swift.

• Add <name of project>-Bridging-Header.h file to project.

• Add import in <name of project>-Bridging-Header.h file.

  #import <GNAdSDK/GNNativeAdRequest.h>
  #import <GNAdSDK/GNNativeAd.h>
  #import <GNAdSDK/GNSNativeVideoPlayerView.h>
