ios - NSURLConnection (initWithRequest vs sendAsyncRequest) -


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 opens new opportunities (e.g. background sessions continue operating if app no longer active).

css - SVG using textPath a symbol not rendering in Firefox -

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
