i have view controller in had added collection view, when pass array of static images shows fine have pass images through gallery selection or camera have used elcimagepicker in project select multiple images, when select multiple images gallery using elcimagepicker select images , when hit done button on top right of firstly not go view controller show images , no images seen in collection view. code is, 

  - (ibaction)select:(id)sender {      elcimagepickercontroller *elcpicker = [[elcimagepickercontroller alloc]   initimagepicker];      elcpicker.maximumimagescount = 4; //set maximum number of images   select, defaults 4      elcpicker.returnsoriginalimage = no; //only return fullscreenimage, not  fullresolutionimage     elcpicker.returnsimage = yes; //return uiimage if yes. if no, return   asset location information      elcpicker.onorder = yes; //for multiple image selection, display , return   selected order of images      elcpicker.imagepickerdelegate = self;      //present modally      [self presentviewcontroller:elcpicker animated:yes completion:nil];   }   - (void)elcimagepickercontroller:(elcimagepickercontroller *)picker   didfinishpickingmediawithinfo:(nsarray *)info{      if([info count] > 0) {          (nsdictionary *imageinfo in info) {              uiimage *image = [imageinfo  valueforkey:uiimagepickercontrolleroriginalimage];              nslog(@"iii %@",image);              _arrimages=image;              nslog(@"ppp %@",_arrimages);              //do here          }      }      [imagepicker dismissviewcontrolleranimated:yes completion:nil];   }  - (void)elcimagepickercontrollerdidcancel:(elcimagepickercontroller *)picker{      [self dismissviewcontrolleranimated:yes completion:null]; }  -(nsinteger)numberofsectionsincollectionview:(uicollectionview *)collectionview{      return 1; }  -(nsinteger) collectionview:(uicollectionview *)collectionview   numberofitemsinsection:(nsinteger)section{      return [_arrimages count]; }  - (uicollectionviewcell *)collectionview:(uicollectionview *)collectionview   cellforitematindexpath:(nsindexpath *)indexpath{      patterncell *cell= [collectionview   dequeuereusablecellwithreuseidentifier:@"cell" forindexpath:indexpath];      nsstring *string=[_arrimages objectatindex:indexpath.row];      nslog(@"image %@",string);      cell.img.image=[uiimage imagenamed:string];      cell.name.text=string;      return cell; }  -(cgsize)collectionview:(uicollectionview *)collectionview layout:  (uicollectionviewlayout *)collectionviewlayout sizeforitematindexpath:(nsindexpath   *)indexpath{      return cgsizemake(150.0, 150.0);}  -(uiedgeinsets)collectionview:(uicollectionview *)collectionview layout:  (uicollectionviewlayout *)collectionviewlayout insetforsectionatindex:  (nsinteger)section{      return uiedgeinsetsmake(5, 5, 5, 5); }

can 1 me i'm making mistake? shows screen, enter image description here

you need pass selected images collectionview.

- (void)elcimagepickercontroller:(elcimagepickercontroller *)picker   didfinishpickingmediawithinfo:(nsarray *)info{      if([info count] > 0) {         (nsdictionary *imageinfo in info) {                 uiimage *image = [imageinfo     valueforkey:uiimagepickercontrolleroriginalimage];              nslog(@"iii %@",image);              _arrimages=image;              nslog(@"ppp %@",_arrimages);                //reload collection view display selected images in cell.            [_collectionview reloaddata];         }      }      [imagepicker dismissviewcontrolleranimated:yes completion:nil];   }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
