蘋果內購 (無力吐槽,暫時先這樣),說說它里面的關鍵步驟.
- 添加收款
銀行卡和商品:http://www.lxweimin.com/p/1e6b1152afc6 - 創建沙盒 測試賬號 : http://www.lxweimin.com/p/143b410ff09a
- 代碼部分
大致 方向是
product_id=>Payment=>喚起蘋果支付
通過 主要是 `SKPaymentTransactionObserver`(觀察支付狀態) 和
`SKProductsRequestDelegate` (通過商品id去蘋果服務器獲取商品信息)
為了方便的開發 我自己封裝了 ApplePay

@property (nonatomic,copy) NSString * currentProductId;
//@property (nonatomic,strong) NSDictionary * mapDic;//product_id -> 金額的映射
@property (nonatomic,weak) id <ZLApplePayDelegate> delegate;
