iOS常用方法 獲取沙盒中的幾個目錄路徑

開發中常遇到需要快取的需求，快取的時候我們就需要有乙個路徑，下面的**是獲取沙盒中的路徑的方法：

//獲取沙盒主目錄路徑

nsstring * homedirectory = nshomedirectory();
nslog(@"home === %@",homedirectory);
//獲取documents目錄路徑
nsarray * documentpaths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);
nsstring * documentdirectory = [documentpaths objectatindex:0];
nslog(@"document === %@",documentdirectory);
//獲取caches目錄路徑
nsarray * cachespaths = nssearchpathfordirectoriesindomains(nscachesdirectory, nsuserdomainmask, yes);
nsstring * cachesdirectory = [cachespaths objectatindex:0];
nslog(@"caches === %@",cachesdirectory);
//獲取tmp目錄路徑
nsstring * tmpdirectory =  nstemporarydirectory();
nslog(@"tmp === %@",tmpdirectory);
