i have facebook login gets users profilepicture, lblusername, , lblemail. know fbprofilepictureview uiview contains uiimageview.

so, asking how convert or "save" profilepicture facebook uiimage? here loginviewcontroller.m. have imported facebook sdk correctly in loginviewcontroller.h file.

#import "loginviewcontroller.h" #import <quartzcore/quartzcore.h>  @interface loginviewcontroller ()  - (void)togglehiddenstate:(bool)shouldhide;  @end  @implementation loginviewcontroller  - (void)viewdidload {     [super viewdidload];      [self togglehiddenstate:yes];     self.lblloginstatus.text = @"";      self.loginbutton.readpermissions = @[@"public_profile", @"email"];     self.loginbutton.layer.cornerradius = 0;     [self.loginbutton.layer setborderwidth:0.0f];      self.loginbutton.delegate = self;   //    uiimageview *image = nil; //     //    (nsobject *pic in [self.profilepicture subviews]) { //        if ([pic ismemberofclass:[uiimageview class]]) { //            uiimageview *objimg = (uiimageview *)pic; //            image = objimg.image; //            break; //        } //    } //     //    self.view.backgroundcolor = [uicolor colorwithpatternimage:image]; //     // additional setup after loading view. }  -(void)togglehiddenstate:(bool)shouldhide{     self.lblusername.hidden = shouldhide;     self.lblemail.hidden = shouldhide;     self.profilepicture.hidden = shouldhide;     self.loggedinwallpaper.hidden = shouldhide;     self.fblogout.hidden = shouldhide; }  -(void)toggleunhiddenstate:(bool)shouldshow{     self.loggedinwallpaper.hidden = no; }  -(void)loginviewshowingloggedinuser:(fbloginview *)loginview{     self.lblloginstatus.text = @"";      [self togglehiddenstate:no];     [self toggleunhiddenstate:yes]; }  -(void)loginviewshowingloggedoutuser:(fbloginview *)loginview{     self.lblloginstatus.text = @"";      [self togglehiddenstate:yes]; }  -(void)loginviewfetcheduserinfo:(fbloginview *)loginview user:(id<fbgraphuser>)user{     nslog(@"%@", user);     self.profilepicture.profileid = user.objectid;     self.lblusername.text = user.name;     self.lblemail.text = [user objectforkey:@"email"];     uistoryboard *storyboard = [uistoryboard storyboardwithname:@"main" bundle:nil];     uiviewcontroller *homeviewcontroller = (uiviewcontroller *)[storyboard instantiateviewcontrollerwithidentifier:@"homeviewcontroller"];     [self presentviewcontroller:homeviewcontroller animated:yes completion:nil];  //     //    (nsobject *obj in [self.profilepicture subviews]) { //        if ([obj ismemberofclass:[uiimageview class]]) { //            uiimageview *objimg = (uiimageview *)obj; //            image = objimg.image; //            break; //        } //    } }    -(void)loginview:(fbloginview *)loginview handleerror:(nserror *)error{     nslog(@"%@", [error localizeddescription]); }  - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }   #pragma mark - navigation  // in storyboard-based application, want little preparation before navigation //- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender { //    uiimage *image = _profilepicture; //    homeviewcontroller *homeviewcontroller = (homeviewcontroller *)segue.destinationviewcontroller; //    homeviewcontroller.homepic = image; //      // new view controller using [segue destinationviewcontroller].     // pass selected object new view controller. //}   @end

i not use image since facebook load different sizes of image , don't know whether low quality version. can't download image in size need it?

facebook uses urls this: http://graph.facebook.com/user_id/picture?width=width&height=height

ofc need swap out user_id user's facebook user id , width , height values need.
