wallet的前身為passbook，2015年WWDC大會蘋果正式改名wallet，passbook是蘋果2012年iOS6開放出來的新功能.可以幫助用戶管理五種類型（Boarding passes（登機(jī)牌），Coupons（優(yōu)惠券），Store cards（購物卡），Event tickets（入場券），Generic（通用卡））的票據(jù)

在iOS中一個(gè)Pass其實(shí)就是一個(gè).pkpass文件，事實(shí)上它是一個(gè)Zip壓縮包，只是這個(gè)壓縮包要按照一定的目錄結(jié)構(gòu)來設(shè)計(jì)
如何創(chuàng)建一個(gè)Pass可以參考Apple的文檔
