iphone - How to Call NSUserDefault Value To Another View Controller? -

// wrote function in separate class file:

-(void)display {     nsuserdefaults *prefs = [nsuserdefaults standarduserdefaults];     nsinteger *position = [prefs integerforkey:@"currentlevel"];     nslog(@"------->%i",position);     //this nslog returning value 6       [prefs synchronize];     } 

//in viewcontroller calling function using object have created class

@interface viewcontroller () {     //display class name     //disp object fro class     display *disp;    }  @implementation viewcontroller  - (void)viewdidload {      disp = [[display alloc]init];       [disp display];     nslog(@"%i",[disp position]);     //this nslog statement returning value 0     [super viewdidload]; } 

if has solution please me.

try implement this..

@implementation classa        - (void)viewdidload         {             [super viewdidload];             // additional setup after loading view, typically nib.             [[nsuserdefaults standarduserdefaults]setinteger:100 forkey:@"currentlevel"];             [[nsuserdefaults standarduserdefaults] synchronize];         }      @end      @implementation classb      - (void)viewdidload     {         [super viewdidload];         // additional setup after loading view, typically nib.            int b = [[[nsuserdefaults standarduserdefaults] integerforkey:@"currentlevel"] integervalue];           nslog(@"interger value %d",b);     }
