ios - I have an error with video settings when creating a video from an array of images in swift -


so i've been having problem while. when creating video file array of images, i've been getting errors linking video settings

let paths = nsfilemanager.defaultmanager().urlsfordirectory(.documentdirectory, indomains: .userdomainmask)     let documentsurl = images[0]     let videowriter: avassetwriter = avassetwriter(url: documentsurl, filetype: avfiletypequicktimemovie, error: nil)      var videosettings: nsdictionary = nsdictionary()      videosettings = [         avvideocodeckey: avvideocodech264,         avvideowidthkey: 1080,         avvideoheightkey: 1920     ]      var exportpath: nsstring = nstemporarydirectory().stringbyappendingformat("/video.mov")     var exporturl: nsurl = nsurl.fileurlwithpath(exportpath string)      var exporter = avassetexportsession(asset: videosettings, presetname: avassetexportpresethighestquality)     exporter.outputurl = exporturl      exporter.exportasynchronouslywithcompletionhandler({         let library = alassetslibrary()         library.writevideoatpathtosavedphotosalbum(exporturl, completionblock: { (asseturl:nsurl!, error:nserror?) -> void in              })     })

so in block of code should create video file array called "images", line 

var exporter = avassetexportsession(asset: videosettings, presetname: avassetexportpresethighestquality)

gives error @ "videosettings" don't understand why happening. error "cannot convert value of type 'nsdictionary' expected argument type 'avasset'"

the line 

let videowriter: avassetwriter = avassetwriter(url: documentsurl, filetype: avfiletypequicktimemovie, error: nil)

also gives error @ 'avassetwriter'

the error "cannot invoke initializer of type 'avassetwriter' argument list of type (url: uiimage, filetype: string, error:_)'"

please can problem, thanks

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; } &l
