[m_items addobject:item];         }     } else if ([dict objectforkey:uiimagepickercontrollermediatype] == alassettypevideo){ // video file         if ([dict objectforkey:uiimagepickercontrolleroriginalimage]){             nsurl* urlpath=[dict objectforkey:@"uiimagepickercontrollerreferenceurl"];             item = [bundleitem itemwithpath:urlpath anddescription:nil];             item.itemimage = [dict objectforkeyedsubscript:uiimagepickercontrolleroriginalimage];             item.itemtype = 2; // video             item.itemsize = // need here??             [m_items addobject:item];         }     } 

edit

getting nscocaoerrordomain 256 videos:

            nsurl* urlpath=[dict objectforkey:@"uiimagepickercontrollerreferenceurl"];              item = [bundleitem itemwithpath:urlpath anddescription:nil];             item.itemimage = [dict objectforkeyedsubscript:uiimagepickercontrolleroriginalimage];             item.itemtype = 2; // video              //error container             nserror *attributeserror;             nsdictionary *fileattributes = [[nsfilemanager defaultmanager] attributesofitematpath:[urlpath path] error:&attributeserror];             nsnumber *filesizenumber = [fileattributes objectforkey:nsfilesize];             long filesize = [filesizenumber longvalue];             item.itemsize = filesize;              [m_items addobject:item]; 

for image data selection:

item.itemimage = (uiimage*)[info valueforkey:uiimagepickercontrolleroriginalimage]; nsdata *imgdata = uiimagejpegrepresentation(item.itemimage, 1); //1 represents quality of image. nslog(@"size of image(bytes):%d",[imgdata length]); 

hope you.

below method generalize, work both image , video:

something should take care finding file size of selected image or video returned uiimagepickercontroller

- (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info {          nsurl *videourl=(nsurl*)[info objectforkey:uiimagepickercontrollermediaurl];          //error container         nserror *attributeserror;         nsdictionary *fileattributes = [[nsfilemanager defaultmanager] attributesofitematpath:[videourl path] error:&attributeserror];         nsnumber *filesizenumber = [fileattributes objectforkey:nsfilesize];         long long filesize = [filesizenumber longlongvalue]; }
