• 在本app打開其他app的時(shí)候，會(huì)調(diào)用一個(gè)共享類的對(duì)象方法是

[[UIApplication sharedApplication] canOpenURL:url];

如果返回yes，系統(tǒng)允許打開，才能分享調(diào)用成功，進(jìn)行分享等接下來的一系列操作，所以需要告訴系統(tǒng)本APP可以打開哪些其他app，方法是在plist文件里(與系統(tǒng)溝通的配置文件)添加其他app的名單

• 那么告訴系統(tǒng)哪些可以打開，那么打開app后如果返回本app怎么實(shí)現(xiàn)呢，這里就用到URL types,在plist文件里輸入U(xiǎn)RL types,告訴系統(tǒng)本app不同的id，在返回的時(shí)候系統(tǒng)依據(jù)注冊(cè)的信息就可找到本app
