ios - Handling Two Login Buttons -

i have login screen app uses facebook login , twitter login. want set if facebook used, users data saved through facebook, , if twitter used uses twitter information.

currently trying if statement profile images alone, doesnt seem working way want... using uibutton twitter login, , fbloginview built in class facebook sdk facebook login. here code snippet if statement in loginviewcontroller.m:

- (void)profilepicturechoose:(id)sender{     if (sender == twloginbutton){         theprofilepicture = twitterprofpicture;     }     else if(sender == fbloginbutton){         theprofilepicture = profpicture;     } } 

i have fb login button linked fbloginbutton property , uibutton twitter liked property twloginbutton. these 2 properties saved in loginviewcontroller.has such:

@property (weak, nonatomic) iboutlet fbloginview *fbloginbutton; @property (strong, nonatomic) iboutlet uibutton *twloginbutton; 

i have these 2 properties profile pictures in same .h file:

@property (nonatomic)  uiimage *profpicture; @property (nonatomic)  uiimage *twitterprofpicture; 

with theprofilepicture variable using access picture controller.

i'm not sure how have if statement check correctly button clicked. if me appreciate it

what giving buttons tag?

 fbloginbutton.tag = 1;  twloginbutton.tag = 2; 

and modify profile picture method follows:

- (void)profilepicturechoose:(id)sender{     if (sender.tag == 1){         //facebook button         theprofilepicture = profpicture;     }     else if(sender.tag == 2){         //twitter button         theprofilepicture = twitterprofpicture;     } }
