You can set your time interval as a class property and access it from there. In example:

@interface YourClass ()

@property (nonatomic, assign) NSTimeInterval myTimeInterval);

@end

@implementation YourClass

- (void)methodWithYourTimerInIt {

    // ... Do stuff
    self.myTimeInterval = 6.0;
    myTimer = [NSTimer scheduledTimerWithTimeInterval:self.myTimeInterval target:self selector:@selector(updatePlayer) userInfo:nil repeats:YES];
}

- (void)updatePlayer {

    NSLog(@"My time interval is: %f", self.myTimeInterval);
}

@end

You can use your timer as:

myTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(updatplayer) userInfo:nil repeats:YES];

- (void)updatplayer {
     long currentPlaybackTime = moviePlayer.currentPlaybackTime;
     playSlider.value = currentPlaybackTime / moviePlayer.duration;
}
