# iOS Implementation of Normal Banner Ads

# Implementation of iOS Banner Ads

Banner ads are placed at bottom or top of application screen.
You can use as an icon-based advertising or in-line advertising depending on the ad size setting.

# Preparation

To implement the banner ads, you need to install Geniee SDK to the project. Please follow the Start Guide for the process. Start Guide

# Class and protocol

iOS banner ad delivery use these following classes;

• GNAdView ---Asynchronous to get a banner ad, the class for display
• GNAdViewDelegate ---Banner advertising cycle event processing protocol

# Acquisition and display of banner ads

0. Add project to GNAdSDK.frameworkStart Guide

1. Import GNAdView.h

#import <GNAdSDK/GNAdView.h>

2. Select protocol GNAdViewDelegate

@interface MyViewController : UIViewController<GNAdViewDelegate>
{
}

3. Declare GNAdView variable

GNAdView *_adView;

4. Initialise GNAdView instance

_adView = [[GNAdView alloc] initWithAdSizeType:GNAdSizeTypeSmall appID:@"YOUR_ZONE_ID"];

or

_adView = [[GNAdView alloc] initWithFrame:CGRectMake(0, 20, 320, 50) adSizeType:GNAdSizeTypeSmall appID:@"YOUR_ZONE_ID"];

initWithAdSizeType,initWithFrame parameter sets Advertising screen layout area.
adSizeType parameter set Advertising size type.
"YOUR_ZONE_ID" set ManagementID of AdvertisingZone on Geniee.

5. Set delegate of GNAdView The banner advertisement processing cycle event will be notified via the delegate. Set the instance variable adopted GNAdViewDelegate protocol.

_adView.delegate = self;

6. Set rootViewController of GNAdView

_adView.rootViewController = self;

7. Add Advertising on the screen.

[self.view addSubview:_adView];

8. load Advertising and display it.

[_adView startAdLoop];

9. When you release the instance of GNAdView, it set refresh stop and delegate to nil.

- (void)dealloc
{
    [_adView stopAdLoop]; 
    _adView.delegate = nil;
}

• Example MyViewController's implementation：

#import <GNAdSDK/GNAdView.h>

@interface MyViewController : UIViewController<GNAdViewDelegate>
{
    GNAdView *_adView;
}
@end

@implementation MyViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    _adView = [[GNAdView alloc] initWithFrame:CGRectMake(0, 20, 320, 50)
                                    adSizeType:GNAdSizeTypeSmall appID:@"YOUR_ZONE_ID"];
    _adView.delegate = self;
    _adView.rootViewController = self;
    [self.view addSubview:_adView];

    _adView.center = CGPointMake(self.view.center.x, _adView.center.y);
    [_adView startAdLoop];
}

- (void)dealloc
{
    [_adView stopAdLoop];
    _adView.delegate = nil;
}

# Setting ad size type

You can deploy as icon-based advertising or in-line advertising based on the size type setting of ad inventory.

• Banner-based advertising : GNAdSizeTypeSmall、GNAdSizeTypeTall、GNAdSizeTypeW320H100

• Icon-based advertising : GNAdSizeTypeW57H57、GNAdSizeTypeW76H76

  The definition of adSizeType	The meaning of definition
  GNAdSizeTypeSmall	320x50
  GNAdSizeTypeTall	300x250
  GNAdSizeTypeW320H100	320x100
  GNAdSizeTypeW57H57	57x57
  GNAdSizeTypeW76H76	76x76

# Banner Rotation (refresh)

From the SSP dashboard, you can set the banner rotation (refresh).
If you set it, it will automatically refreshed with ads interval specified number of seconds (30 to 120).
If you want to stop the refresh, please follow this steps;

• From the SSP dashboard and disable "Enable banner rotation".

• Call stopAdLoop function.

  - (void)dealloc
  {
      [_adView stopAdLoop];
      _adView.delegate = nil;
  }

# GNAdViewDelegate protocol

• Implement CallBack function of GNAdViewDelegate, you will receive the advertisement processing cycle events.

  @protocol GNAdViewDelegate <NSObject>
  
  @optional
  
  /// It will be sent when the reading of the advertising data has been completed.
  - (void)adViewDidReceiveAd:(GNAdView *)adView;
  
  /// It will be sent when that failed to read the ad in the cause such as a network error.
  - (void)adView:(GNAdView *)adView didFailReceiveAdWithError:(NSError *)error;
  
  /// It will be sent immediately before the terminal of the browser by advertising of touch is started.
  - (BOOL)shouldStartExternalBrowserWithClick:(GNAdView *)adView landingURL:(NSString *)landingURL;
  
  /// Will be sent immediately before the terminal of the browser by advertising of touch is started.
  - (void)adViewWillShowInDefaultBrowser:(GNAdView *)adView;
  
  /// Ad is tapped, will be sent immediately before the in-app browser is started.
  - (void)adViewWillShowInInternalBrowser:(GNAdView *)adView;
  
  /// It will be sent immediately before the terminal of the browser is started up by the operation of the in-app browser.
  - (void)adViewWillShiftToDefaultBrowser:(GNAdView *)adView;
  
  /// It will be sent immediately before the application within the browser is closed.
  - (void)adViewWillTerminateInternalBrowser:(GNAdView *)adView;
  
  @end

# Control of screen transition landing page

Landing page of Ads will start on an external browser by default.
CallBack function implementation of GNAdViewDelegate to start in-app browser with URL of the landing page.
In addition, by the return value of function you can control to not launch an external browser.

• YES → Start external browser.

• NO → Don't start external browser.

  /**
   * Sent before ad begins open landingURL in External Browser.
   *
   * @param adView The GNAdView Ad.
   * @param landingURL The URL of the landing page.
   * @return BOOL YES if the ad should begin start External Browser; otherwise, NO .
   */

# Expansion and contraction of the advertising display area

Expansion and contraction of the advertising display area.

• Change of the display area

  _adView = [[GNAdView alloc] initWithFrame:CGRectMake(0, 20, 320, 50)
                                  adSizeType:GNAdSizeTypeSmall appID:@"YOUR_ZONE_ID"];
  _adView.delegate = self;
  _adView.rootViewController = self;
  [self.view addSubview:_adView];
  // Expansion of 320x50 banner ad
  // frame:Display area ,adSize:Set in SSP dashboard ad sizes
  [_adView showBannerWithFrame:CGRectMake(0, 20, 375, 58)
                                  adSize:CGSizeMake(320, 50)];

# For use of the iOS SDK from Swift

To use iOS SDK (Objective-C) class from the Swift, you need to write the import statement of the header files in a file called Objective-C bridging header.

• Add <ProjectName>-Bridging-Header.h file to the project.

• Describes the import statement in <ProjectName>-Bridging-Header.h file.

  #import <GNAdSDK/GNAdView.h>
  

  1
  

• Set the file name in the "Build Settings" in the project. Select target from Project Root, and set <ProjectName>-Bridging-Header.h to 「Build Settings」->「Swift Compiler - Code Generation」->「Objective-C bridging header」

• Example implementation of MyViewController.swift：

  import UIKit
  
  class MyViewController: UIViewController, GNAdViewDelegate {
  
      var _adView : GNAdView = GNAdView(adSizeType:GNAdSizeTypeSmall, appID:"YOUR_ZONE_ID")
  
      override func viewDidLoad() {
          super.viewDidLoad()
          
          _adView.delegate = self
          _adView.rootViewController = self
          //_adView.bgColor = YES
          //_adView.geoLocationEnable = YES
          //_adView.GNAdlogPriority = GNLogPriorityInfo
          _adView.center = CGPointMake(self.view.center.x, _adView.center.y);
          
          self.view.addSubview(_adView)
          _adView.startAdLoop()
      }
  
      func shouldStartExternalBrowserWithClick(nativeAd: GNAdView, landingURL: String) -> Bool {
          NSLog("ViewController: shouldStartExternalBrowserWithClick : %@.", landingURL);
          return true;
      }
  }
