在上一篇文章中主要是编写了iOS Admob的接口实现。那么现在我们要做的事就是在unity中调用iOS Admob并展示。

一、实现Unity中对外接口，内部负责调用iOS Admob接口。
LHiOSAdmob.cs

using UnityEngine;using System.Collections;using System.Runtime.InteropServices;using System.Linq;using System.Collections.Generic;public enum GADAdSize:int{// iPhone and iPod Touch ad size. Typically 320x50.kGADAdSizeBanner = 1,// Taller version of kGADAdSizeBanner. Typically 320x100.kGADAdSizeLargeBanner,// Medium Rectangle size for the iPad (especially in a UISplitView's left pane). Typically 300x250.kGADAdSizeMediumRectangle,// Full Banner size for the iPad (especially in a UIPopoverController or in// UIModalPresentationFormSheet). Typically 468x60.kGADAdSizeFullBanner,// Leaderboard size for the iPad. Typically 728x90.kGADAdSizeLeaderboard,// Skyscraper size for the iPad. Mediation only. AdMob/Google does not offer this size. Typically// 120x600.kGADAdSizeSkyscraper,// An ad size that spans the full width of the application in portrait orientation. The height is// typically 50 pixels on an iPhone/iPod UI, and 90 pixels tall on an iPad UI.kGADAdSizeSmartBannerPortrait,// An ad size that spans the full width of the application in landscape orientation. The height is// typically 32 pixels on an iPhone/iPod UI, and 90 pixels tall on an iPad UI.kGADAdSizeSmartBannerLandscape}public class LHiOSAdmob : MonoBehaviour {[DllImport("__Internal")]private static extern void startRequestAdmob(string admobId, int adSizeId, float pixelX, float pixelY);[DllImport("__Internal")]private static extern void setAdmobHidden(bool isHidden);public static LHiOSAdmob Instance;private GADAdSize adSize;void Awake(){// singletonif (Instance != null){Debug.LogError("Multiple instances of LHiOSAdmob");}Instance = this;}// Init google admob// It will request the admob after five seconds.// It's will auto show admob.public void InitAdmob(string admobId, GADAdSize size, Vector2 pos){#if UNITY_IPHONEint adSizeId = (int)size;startRequestAdmob(admobId, adSizeId, pos.x, pos.y);#elseDebug.Log("Admob only run on iPhone platform");#endif}// Set Admob BannerView is visible or notpublic void SetAdmobVisible(bool isVisible){#if UNITY_IPHONEsetAdmobHidden(!isVisible);#elseDebug.Log("Admob only run on iPhone platform");#endif}// Use this for initializationvoid Start () {}// Update is called once per framevoid Update () {}}

这是一个单例接口类，内部负责调用iOS Admob接口，并开放对外接口。供其他c#文件调用。
注意：你可以制作一个Prefab，并包含该脚本。将该Prefab拖放到场景中。在需要显示admob的地方调用。

二、测试admob显示，也就是在你需要的地方。

TestAdmob.cs

using UnityEngine;using System.Collections;public class TestAdmob : MonoBehaviour {// Use this for initializationvoid Start () {LHiOSAdmob.Instance.InitAdmob("your admob id", GADAdSize.kGADAdSizeSmartBannerLandscape, new Vector2(0, 150));}// Update is called once per framevoid Update () {}}

ok, 现在可以Build iOS工程了。

注意：

Build的iOS工程，要添加对应的编译选项和iOS框架。

1、Other Linker Flags 添加 -ObjC

2、Xcode->Targets->Build Phases->Link Binary With Libraries 添加以下框架：
AdSupport
AudioToolbox
AVFoundation
CoreGraphics
MessageUI
StoreKit
SystemConfiguration
