if both initwithrequest , sendasyncrequest asynchronous ways of connections whats major difference ? other completion handler , queue concept in sendasyncreq else ? 1 more advantageous ?? the sendasynchronousrequest simpler , easier use, saving implementing nsurlconnectiondatadelegate , nsurlconnectiondelegate methods. if need richness of delegate approach (e.g. challenge-based authentication, need cancelable requests, etc.), sendasynchronousrequest not job. if targeting ios 7 , later, consider nsurlsession , instead, too. can enjoy simplicity of block-based networking , still enjoy delegate methods if , when needed. requests cancelable. opens new opportunities (e.g. background sessions continue operating if app no longer active).

i have got site , multiple sub-sites under it. problem i'm having js files located in style library of master site, , users don't have access master site getting access denied errors. i'm guessing might related sub-sites don't have direct access style library of master, i'm not sure. (i'm not sure whether makes sense or not, i'm newbie.) does have solution this? thanks in advance. if users don't have access style library in parent or root site, you're going need give them access. can set library unique permissions , give read access. have several site collections set way, resources stored in single style library , given open access allow users in subsites access.
