檢視 Interstitial Ads 的原始碼

Interstitial廣告可以在app啟動, 視頻載入期間或遊戲暫停的時候，呈現內容豐富的HTML5網頁或Web App。。<br>
以下將告訴您如何讓您的app顯示Interstitial廣告。

== 增加TWMTAMediaInterstitialView ==
TWMTAMediaInterstitialView是NSObject的子類別，透過以下步驟可以很簡單的將Interstitial廣告加入App中：
:* Import TWMTAMediaInterstitialView.h
:* 宣告一個TWMTAMediaInterstitialView的實體在顯示Interstitial廣告的UIViewController
:* alloc & init TWMTAMediaInterstitialView
:* 載入廣告

 #import "TWMTAMediaViewController.h"
 
 #import "TWMTAMediaView.h"
 #import "TWMTAMediaInterstitialView.h"
 
 @interface TWMTAMediaViewController () <TWMTAMediaViewDelegate, TWMTAMediaInterstitialViewDelegate>
 {
     TWMTAMediaView *_adView;
     TWMTAMediaInterstitialView *_interstitialView;
 }
 @end
 
 @implementation TWMTAMediaViewController
 
 //@synthesize _adView;
 
 - (void)viewDidLoad
 {
     [super viewDidLoad];
 	// Do any additional setup after loading the view, typically from a nib.
 	
 	CGRect frame = CGRectMake(0, 0, [UIScreen mainScreen].applicationFrame.size.width, [UIScreen mainScreen].applicationFrame.size.height);
     _interstitialView = [[TWMTAMediaInterstitialView alloc] initWithFrame:frame
                                                                    slotId:@"h0Lz1374718054864uDt"
                                                               developerID:@""
                                                                gpsEnabled:YES
                                                                  testMode:NO];
     [_interstitialView receiveAd];
     
 }
 
 @end

當Interstitial廣告載入完成且要呈現時才需要呼叫showAd:方法
 [_interstitialView showAd:self.view];

== TWMTAMediaInterstitialViewDelegate ==
你可以選擇透過實現全部或部分的TWMTAMediaInterstitialViewDelegate方法來追踪Interstitial廣告的生命週期
 @protocol TWMTAMediaInterstitialViewDelegate <NSObject>
 @optional
 
 - (void)interstitialViewWillLoadAd:(TWMTAMediaInterstitialView *)view;
 
 - (void)interstitialViewDidLoadAd:(TWMTAMediaInterstitialView *)view;
 
 - (void)interstitialView:(TWMTAMediaInterstitialView *)view didFailToReceiveAdWithError:(NSError *)error;
 
 - (BOOL)interstitialViewActionShouldBegin:(TWMTAMediaInterstitialView *)view willLeaveApplication:(BOOL)willLeave;
 
 - (void)interstitialViewWillDisappear:(TWMTAMediaInterstitialView *)view;
 
 - (void)interstitialViewDidDisappear:(TWMTAMediaInterstitialView *)view;
 
 @end

你可以在UIViewController中實現TWMTAMediaInterstitialViewDelegate方法
 #import "TWMTAMediaViewController.h"
 
 #import "TWMTAMediaInterstitialView.h"
 
 @interface TWMTAMediaViewController () <TWMTAMediaInterstitialViewDelegate>
 {
 }
 @end

並且透過TWMTAMediaInterstitialView的setDelegate:方法來指定實現TWMTAMediaInterstitialViewDelegate的對象
 [_interstitialView setDelegate:self];

請注意，如果你有實現TWMTAMediaInterstitialViewDelegate，當TWMTAMediaInterstitialView不再被使用時，必須將delegate設定為nil
 - (void)dealloc
 {
     _interstitialView.delegate = nil;
     
     // Don't release the _adView if you are using ARC in your project
     [_interstitialView release];
     
     _interstitialView = nil;
 }

==== - (void)interstitialViewWillLoadAd:(TWMTAMediaInterstitialView *)view ====
TWMTAMediaInterstitialView開始載入廣告前會先呼叫這個方法
 - (void)interstitialViewWillLoadAd:(TWMTAMediaInterstitialView *)view
 {
     NSLog(@"%@ interstitialViewWillLoadAd", view);
 }

==== - (void)interstitialViewDidLoadAd:(TWMTAMediaInterstitialView *)view ====
你可以在確定廣告已經載入後才將TWMTAMediaInterstitialView加入UI
 - (void)interstitialViewDidLoadAd:(TWMTAMediaInterstitialView *)view
 {
     NSLog(@"%@ interstitialViewDidLoadAd", view);
     [_interstitialView showAd:self.view];
 }

==== - (void)interstitialView:(TWMTAMediaInterstitialView *)view didFailToReceiveAdWithError:(NSError *)error ====
你可以在這裡的得知載入廣告過程中發生的何異常
 - (void)interstitialView:(TWMTAMediaInterstitialView *)view didFailToReceiveAdWithError:(NSError *)error
 {
      NSLog(@"%@ interstitialViewdidFailToReceiveAdWithError:%@", view, error.description);
 }

==== - (BOOL)interstitialViewActionShouldBegin:(TWMTAMediaInterstitialView *)view willLeaveApplication:(BOOL)willLeave ====
當使用者點擊廣告後，TWMTAMediaView在開啟網頁或App Store前會先通知你
 - (BOOL)interstitialViewActionShouldBegin:(TWMTAMediaInterstitialView *)view willLeaveApplication:(BOOL)willLeave
 {
     NSLog(@"%@ interstitialViewwillLeaveApplication:%i", view, willLeave);
     return YES;
 }
