calling method repeatedly after 3 seconds time interval in background

I have gone through many sites but still no answer.

I have a method suppose void xyz(), which will get called automatically from a View Controller after every 3 seconds.

I have no idea what to use, do I have to use NSThread or PerformSelector.

[NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector:@selector(runMethod) userInfo:nil repeats:YES];

You should use NSTimer as mentioned by @mokujin. Please visit https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSTimer_Class/Reference/NSTimer.html

Use NSTimer

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector:@selector(xyz) userInfo:nil repeats:YES];

Something like this 

-(void)xyz{
        [self performSelectorInBackground:@selector(xyz) withObject:nil];
    }

- (void)viewDidLoad  {
   [self performSelector:@selector(xyz) withObject:nil afterDelay:0.3];
 }
