最近接到一個(gè)有關(guān)騰訊廣告推廣應(yīng)用的渠道，需要實(shí)現(xiàn)，就是用到了廣點(diǎn)通，而它的坑爹之處就在于，iOS版本的接入方式只有API，沒有SDK，所以需要我們開發(fā)人員去逐字逐句理解然后實(shí)現(xiàn)調(diào)用他們服務(wù)端的接口，然而這個(gè)并不僅僅是一個(gè)接口調(diào)用那么簡(jiǎn)單；各種碼的獲取，各種加密方式，簡(jiǎn)直讓人蛋碎，最主要的是人家TX的技術(shù)支持聽說忙的不行，一般是不會(huì)理你的，API里面是Python語言寫的什么異或的東西，居然讓我一個(gè)寫OC的自己搞定，所以經(jīng)過這次蹚坑我決定把我的實(shí)現(xiàn)分享給大家，以便后來人乘涼??--------

引入頭文件

#import <CommonCrypto/CommonDigest.h>
#import <AdSupport/ASIdentifierManager.h>
#import "ZRGTMBase64.h" 
#import "RequestModel.h" //封裝的數(shù)據(jù)請(qǐng)求類

定義基本的宏變量

//以下四個(gè)key是在創(chuàng)建一個(gè)轉(zhuǎn)化成功之后生成的（詳見文章最后備注）
#define gdt_encrypt_key @"xxxxxxxxxx"
#define gdt_sign_key    @"xxxxxxxxxx"
#define gdt_app_id      @"xxxxxxxxxx"
#define gdt_advertiser_id @"xxxxxxx"

#define adGetKey @"ZRAdDowlondCountObjectKey"
#define CC_MD5_DIGEST_LENGTH 16

用到的兩個(gè)屬性

@property (nonatomic,strong)RequestModel *requestModel;
@property (nonatomic,strong) NSMutableArray *adArray;

具體代碼實(shí)現(xiàn)
