ios - Xcode 8.3 and Swift 3 :Display Image in Cell in UICollectionView from URL fetched and Stored in NSMutableArray -

-



i have fetched data web service using following piece of code

func ws_getrelatedrresourcepath(_ rresourceid:int, arrrresourceids:nsarray) {     let refid = arrrresourceids.object(at: rresourceid);      albummodel.getrelatedrresourcepath(parameters: refid anyobject?) { (responseobject,success) in          if(success){             let tempresp = responseobject;              if tempresp != nil  {                 self.arrrelatedrresource.add(tempresp!)             }else {             if(responseobject != nil){                 print(responseobject!);             }         }          if rresourceid < arrrresourceids.count - 1 {             self.ws_getrelatedrresourcepath(rresourceid + 1, arrrresourceids: arrrresourceids);         }else{             print("done.")             self.collectionsameseriesmedia.reloaddata();             self.setupmediaview();             apputils.stoploading();         }     }

by implementing getting url of image stored in nsmutablearray named arrrelatedrresource.

i passing array cellforitemat follows

let cell = collectionsameseriesmedia.dequeuereusablecell(withreuseidentifier: "sameseriesmediaidentifier", for: indexpath) as! mediadetailscollectionviewcell          var strimagepath = arrrelatedrresource[indexpath.row] as! string         print(strimagepath);         strimagepath = (strimagepath anyobject).replacingoccurrences(of: "\\" , with: "");          strimagepath = strimagepath.replacingoccurrences(of: "\"" , with: "");         print(strimagepath)         cell.imgsameseriesmedia.sd_setimage(with: url(string: strimagepath))         return cell

edited :- (solved)

the problem array in storing data. array storing url "". solved silly issue adding following line of code in it.

  strimagepath = strimagepath.replacingoccurrences(of: "\"" , with: "");

the issue solved this.

use sd_setimage completion handler , check if ur getting nil image.

var strimagepath = arrrelatedrresource[indexpath.row] as! string  strimagepath = strimagepath.addingpercentencoding(withallowedcharacters: characterset.urlqueryallowed)!      let url = url(string: strimagepath) if let url = url{    nslog("url = %@",url)     cell.imgsameseriesmedia.sd_setimage(with: url url!, placeholderimage: nil, options: sdwebimageoptions(), completed: { (image: uiimage?, error: error?, cachetype: sdimagecachetype, imageurl: url?) in                         if image != nil{                            cell.imgsameseriesmedia.backgroundcolor = uicolor.green                         }                         else{                           cell.imgsameseriesmedia.backgroundcolor = uicolor.blue                         }                     }) }

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
