swift - Play video downloaded through CloudKit as CKAsset - iOS -


i'm making app records video, uploads icloud using cloudkit ckasset, downloads file , plays in avplayer. written in swift 2.0

i have gotten data downloaded, , think i've been able reference i'm not sure. data/garbage print when convert url nsdata object , print console. video files gets downloaded binary file however. able go cloudkit dashboard , download file , append '.mov' it, , opened in quicktime no problem.

so think main issue can't work out how video file play, since file has no extension. have tried appending '.mov' end urlbyappendingpathextension() no avail. let me know of ideas!

upload video

func imagepickercontroller(picker: uiimagepickercontroller, didfinishpickingmediawithinfo info: [string : anyobject]) {     let tempurl = info[uiimagepickercontrollermediaurl] as! nsurl      dismissviewcontrolleranimated(true) { () -> void in         self.uploadvideotoicloud(tempurl)         print("\n     before upload: \(tempurl)\n")     } }  func uploadvideotoicloud(url: nsurl) {     let videorecord = ckrecord(recordtype: "video", recordid: id)      videorecord["title"] = "this title"      let videoasset = ckasset(fileurl: url)     videorecord["video"] = videoasset      ckcontainer.defaultcontainer().privateclouddatabase.saverecord(videorecord) { (record, error) -> void in         dispatch_async(dispatch_get_main_queue(), { () -> void in             if error == nil {                 print("upload successful")              } else {                 print(error!)             }         })     } }

download video

func downloadvideo(id: ckrecordid) {      privatedatabase.fetchrecordwithid(id) { (results, error) -> void in          dispatch_async(dispatch_get_main_queue()) { () -> void in             if error != nil {                      print(" error fetching record  " + error!.localizeddescription)             } else {                 if results != nil {                     print("pulled record")                      let record = results!                     let videofile = record.objectforkey("video") as! ckasset                      self.videourl = videofile.fileurl                      print("     after download: \(self.videourl!)")                      self.videoasset = avasset(url: self.videourl!)                     self.playvideo()                  } else {                     print("results empty")                 }             }         }     } }

the root problem avplayer expects file extension, example .mov, ckasset's fileurl property points file lacks extension. cleanest solution create hard link, avoids shuffling megabytes of data around , requires no disk space:

- (nsurl *)videourl {     return [self createhardlinktovideofile]; }   - (nsurl *)createhardlinktovideofile {     nserror *err;     if (![self.hardurl checkresourceisreachableandreturnerror:nil]) {         if (![[nsfilemanager defaultmanager] linkitematurl:self.asset.fileurl tourl:self.hardurl error:&err]) {             // if creating hard link failed still possible create copy of self.asset.fileurl , return url of copy         }     }     return self.hardurl; }  - (void)removehardlinktovideofile {     nserror *err;     if ([self.hardurl checkresourceisreachableandreturnerror:nil]) {         if (![[nsfilemanager defaultmanager] removeitematurl:self.hardurl error:&err]) {         }     } }  - (nsurl *)hardurl {     return [self.asset.fileurl urlbyappendingpathextension:@"mov"]; }

then in view controller, point avplayer videourl instead of asset.fileurl.

morning, i have code takes string of shoe sizes, explodes , puts in table. code works , info displayed correctly on page after table there few 1's after table. i'm confused this. so table looks (in columns of 3 on webpage) available in following sizes: 3 4 5 6 9 10 111 here's codes, purpose of example $x = 3|4|6|10|9 function get_sizes_pipe($x) { $counter = 0; $splits = explode("|",$x); asort($splits); $x = print "<table class='greentable'>"; $x .= print "<thead><tr><th scope='col' colspan='3' abbr='starter'>available in following sizes:</th></tr></thead><tbody><tr>"; foreach ($splits $split) { $entry = print "<td>".$split."</td>"; if($counter == 2){ $entry .= print "</tr><tr>"; $counter =0; } else { $counter++; ...
