審核被拒了，原因是上面的，我估計(jì)是Documents文件夾下面有個(gè)文件夾有圖片、html、js等的原因。

其中有人回答如下，記錄一下

You should store any large sized data that is created while your app is running or when it starts for the first time in the /cache directory and not in the /documents directory (e.g. database files). You may save smaller files in the /documents directory though (e.g. settings or a configuration file which is just a few KBytes large).

在iCloud容器中存儲數(shù)據(jù)

從iOS 5開始，每種設(shè)備上的Settings應(yīng)用都有一個(gè)iCloud部分，可以讓用戶看到iClound中有多少數(shù)據(jù)用于備份，有多少數(shù)據(jù)用于應(yīng)用的同步。當(dāng)文件存儲在iCloud容器中，用戶看到的就是一大塊數(shù)據(jù)；而當(dāng)存儲在Documents目錄下，用戶能看到獨(dú)立的文件以及大小。Documents目錄下的文件可以挨個(gè)兒刪除，但沒有存儲在這個(gè)目錄下的數(shù)據(jù)看起來就是一大塊，只能同時(shí)刪除。為避免混淆并方便操作，應(yīng)該把所有用戶生成的文件存儲在Documents目錄下，而把不想讓用戶看到的繁雜的元數(shù)據(jù)存儲在這個(gè)目錄之外。

?關(guān)于iCloud備份的一些信息

在iOS 5以前，當(dāng)設(shè)備跟iTunes同步時(shí)，應(yīng)用的Documents文件夾下的內(nèi)容會自動備份。在iOS 5及后續(xù)版本的設(shè)備上，這些內(nèi)容會備份到iCloud，但開發(fā)者手動保存在iCloud的Documents中的數(shù)據(jù)不會包括在備份中（因?yàn)樗鼈円呀?jīng)在iCloud中了）。要注意這個(gè)自動備份和iCloud同步是不同的。備份文檔被當(dāng)做不透明的數(shù)據(jù)，只能用來完全恢復(fù)一個(gè)iOS設(shè)備。而無論是通過編程還是用戶，都無法訪問單個(gè)文件。
