ApplePay測試開發心得

ApplePay測試開發心得

---

上週本身測試了一下ApplePay的開發. 今天面試的一個iOS開發, 我說ApplePay和3D-Touch, 那貨居然一愣一愣的... 看來仍是有不少人不太會的, 分享一下吧, 讓更多的人學習.

不試不知道, 一試嚇一跳, ApplePay開發居然這麼簡單....

蘋果ApplePay開發文檔 對於這種新技術, 最靠譜的就是蘋果的開發文檔了, 對染全是英文的, 可是看多了天然就能看懂了, 做爲一名iOS程序猿, 我認爲好好養成讀蘋果官方文檔這個習慣仍是不錯的.

第一步: 配置環境

Applepay配置環境 蘋果官方寫的這麼詳細, 我就不寫了, 按照步驟一步一步來就好了.

配置環境的過程就這麼簡單, 可是一步也不能少, 必須所有配置完.

第二步: 上代碼

Apple Pay，是蘋果公司在2014蘋果秋季新品發佈會上發佈的一種基於NFC的手機支付功能，於2014年10月20日在美國正式上線。 2014年秋季applepay面世, 2016.2.18 ApplePay正式登錄中國, 說這些廢話是想表達, ApplePay是個新東西, 因此它必定不會太難 ! 另外 蘋果官方文檔上面, 對代碼部分也有很詳細的教程.

如下代碼就是喚出蘋果支付的控制器, 可喚出控制器以前進行一些基本的設置. 詳情請看註釋, 也是很簡單的, 咱們能夠經過代碼設置是否展現收貨地址, 發票地址擡頭等信息, 也能夠設置默認的聯繫人, 付款信息等.

本身能夠根據本身項目須要進行設置. 代理方法中的didAuthorizePayment:將在用戶受權成功後調用, 受權成功以後咱們能夠經過代理方法參數中的payment拿到PKPaymentToken(用於去請求銀聯支付), 發票擡頭, 收貨地址, 收貨人等等信息. 這些信息也能夠經過PKPaymentAuthorizationViewControllerDelegate中其它的代理方法拿到.
