objective c - iOS: Wait for asynchronous method before populating a tableview -


i'm getting data server need use metadata creating table view. problem data loads asynchronously flow of app. i'm sure simple fix, how can either pause flow of app until data has loaded server, or update table view data becomes available?

thanks!

first, make sure data source methods written correctly if there no data yet, table indeed empty. because data source methods called when table first appears, before have data.

then, when there is data, call reloaddata (on main thread!). same data source methods run again, time there data.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
