ios - calling void with NSUserDefaults -

i making simple ios game. game levels in void.

so when when level gets completed calling void code

[self levelthreevoid]; 

it works great. want save current void in nsuserdefaults , call when app opened user.

please if know answer. making me insane.

edit

adding code comments easier reading.

-(void)yoluc{      self.oyunpicone.image = [uiimage imagenamed:nil];     self.oyunpictwo.image = [uiimage imagenamed:nil];     self.oyunpicthree.image = [uiimage imagenamed:nil];     self.oyunpicfour.image = [uiimage imagenamed:nil];     [herfbiroutlet settitle:@"" forstate:uicontrolstatenormal];     xaltext.text = [nsstring stringwithformat:@"%d",xal+50];     // qiziltext.text = [nsstring stringwithformat:@"%d",qizil+3];  } 

to store variables of interests, write below code in "void" function:

nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; [defaults setobject:value1 forkey:@"uniquekey1"]; [defaults setobject:value2 forkey:@"uniquekey2"]; [defaults synchronize]; 

to retrieve save data next time user logs app, can write below code in viewdidload/viewdidappear method or method of choice gets called upon app launch:

nsuserdefaults *defaults; defaults = [nsuserdefaults standarduserdefaults]; value1 = [defaults objectforkey:@"uniquekey1"]; value2 = [defaults objectforkey:@"uniquekey2"]; 

note way values retrieved based on "uniquekey's". don't duplicate them across different variables. if want overwrite them, use same key once again. hope helps!
