檢視 Expandable 的原始碼

擴張式廣告結合了橫幅及插頁式廣告, 讓橫幅廣告被點擊後先不會因打開瀏覽器app而離開廣告所在的app, 讓使用者可以在同一個app裡全版面的豐富體驗



== 加入 ExpandableView ==
Expandable廣告使用 '''TADBannerView class''' 來實現擴張的行為
以 TADBannerView 的加入方法來加入

==== ExpandableViewController.h ====
 '''// 匯入TADBannerView.h'''
 #import "TADBannerView.h"
 #import "TADBannerViewDelegate.h"
 
 @interface BannerViewController : UIViewController <TADBannerViewDelegate>{
     '''// 宣告 bannerView 為 instance variable'''
     TADBannerView *bannerView;
 }
 @end

==== ExpandableViewController.m ====
 #import " ExpandableViewController.h"
 
 @implementation BannerViewController
 
 - (void)viewDidLoad {
 [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
 
 '''// 建立新的橫幅在螢幕上方, Adsize 定義在TADAdsize.h中'''
 bannerView = [[TADBannerView alloc] initWithAdSize:kTADAdSizeBanner];
 '''// 指定廣告Unit ID'''
 bannerView.adUnitID = MY_BANNER_UNIT_ID;
 '''// 指定detegate'''
 bannerView.delegate = self;
 '''// 指定rootViewController'''
 bannerView.rootViewController = self; 
 '''// 將廣告view 加入self.view並請求廣告'''
 [self.view addSubview:_bannerView]; 
 [bannerView loadRequest: [TADRequest request]];
 }
 
 @end




== 特別注意 ==
在 ViewController 的 view 即將消失前, 必須要將 bannerView 本身以及其 delegate 設定為 nil

 - (void)viewWillDisappear:(BOOL)animated {
   '''// view消失前, 必須要將bannerView物件及delegate設為nil'''
   bannerView.delegate = nil;
   bannerView = nil;
 }

若要將Expandable的Banner放在螢幕下方, 建立時可定義origin

 '''// 建立新的橫幅在螢幕下方, Adsize 定義在TADAdsize.h中'''
 bannerView = [[TADBannerView alloc] initWithAdSize:kTADAdSizeBanner origin:CGPointMake(0, self.view.frame.size.height - 50)];




== TADBannerViewDelegate ==
 @protocol TADBannerViewDelegate <NSObject>
 @optional
 // Ad Request Lifecycle Notifications
 - (void)adViewDidReceiveAd:(TADBannerView *)view;
 - (void)adView:(TADBannerView *)view didFailToReceiveAdWithError:(TADRequestError *)error;
 
 // Click-Time Lifecycle Notifications
 - (void)adViewWillPresentScreen:(TADBannerView *)adView;
 - (void)adViewWillDismissScreen:(TADBannerView *)adView;
 - (void)adViewDidDismissScreen:(TADBannerView *)adView;
 - (void)adViewWillLeaveApplication:(TADBannerView *)adView;
 
 @end

==== - (void)adViewDidReceiveAd:(TADBannerView *)view ====
廣告載入成功後被呼叫, 可以在這裡呈現廣告

==== - (void)adView:(TADBannerView *)view didFailToReceiveAdWithError:(TADRequestError *)error ====
廣告載入失敗後被呼叫

==== - (void)adViewWillPresentScreen:(TADBannerView *)adView ====
廣告即將被呈現之前被呼叫

==== - (void)adViewWillDismissScreen:(TADBannerView *)adView ====
廣告即將被關閉之前被呼叫

==== - (void)adViewDidDismissScreen:(TADBannerView *)adView ====
廣告被關閉之後被呼叫

==== - (void)adViewWillLeaveApplication:(TADBannerView *)adView ====
應用程式及將改在背景執行或中止運作前被呼叫
