i had same problems, , have been using code quite yours. try this, works sure, using:

- (nsstring *)randomstringwithlength:(int)length     {          nsstring *letters = @"abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789";         nsmutablestring *randomstring = [nsmutablestring stringwithcapacity:length];          (int = 0; < length; i++) {             [randomstring appendformat: @"%c", [letters characteratindex: arc4random() % [letters length]]];         }          return randomstring;     }  -(bool)uploadimagefile:(nsstring *)filename     {         nsmutableurlrequest *request= [[nsmutableurlrequest alloc] init];         [request seturl:[nsurl urlwithstring:@"yoururl"]];          [request sethttpmethod:@"put"];         nsstring *boundary = [self randomstringwithlength:14];         nsstring *contenttype = [nsstring stringwithformat:@"multipart/form-data; boundary=%@",boundary];         [request addvalue:contenttype forhttpheaderfield: @"content-type"];         nsmutabledata *postbody = [nsmutabledata data];         nsdata *data = [nsdata datawithcontentsoffile:filename];         [postbody appenddata:[nsdata datawithdata:data]];         [request sethttpbody:postbody];          nsurlresponse *urlresponse = nil;         nserror *requesterror = nil;         nsdata *responsedata = [nsurlconnection sendsynchronousrequest:request returningresponse:&urlresponse error:&requesterror];          if (((nshttpurlresponse *)urlresponse).statuscode != 201) {             nslog(@"unable upload file: %@, response data: %@, response code: %i, request error: %@", [filename lastpathcomponent], [[nsstring alloc] initwithdata:responsedata encoding:nsutf8stringencoding], ((nshttpurlresponse *)urlresponse).statuscode, requesterror);             return no;         }          nslog(@"uploading file successful");         return yes;      }
