PS:上面的程式碼部分，再檢視某些文章時，發現“系統IOS7.0以上獲取支付驗證憑證的方式應該改變，切驗證返回的資料結構也不一樣了”，最後通過實際專案發現支付驗證憑證採用原來的方式“transaction.transactionReceipt”即可。

使用方法：
1 在AppController.mm中進行初始化：
在函式“- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions”中
呼叫“[[SDKApplePay getInstance] initSDK:viewController sdkName:@"applepay"];“進行初始化；
2 在需要呼叫支付的部分呼叫支付程式碼：
[[SDKApplePay getInstance] requestProductsPay:appleProductId]; 支付道具的id（appleProductId的值）例：com.xxxx.xxxx.buy01
這個id是你在蘋果後臺申請的id。
