How to use motion for transition instead touches.

Question

I am building the simple game using sprite kid (the tutorial that treehouse provide us); but I will like to ad the ability to shake the phone in order to make the transition from launch image to background image ( As we did building cristal ball, "touch or shake to get a prediction"). I already did the touch transition right just fallowing step by step the video but when I wrote the code for "motion", nothing happened. Can someone tell me whats is wrong 
Here is the code I wrote:

//  TNTitleScene.m

import "TNTitleScene.h"
import "TNGamePlayScene.h"
@implementation TNTitleScene
-(id)initWithSize:(CGSize)size {
  if (self = [super initWithSize:size]) {
    /* Setup your scene here */
SKSpriteNode *background =[SKSpriteNode spriteNodeWithImageNamed:@"Launch"];
background.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
[self addChild:background];
  }
  return self;
}
-(void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
  TNGamePlayScene *gamePlayScene = [TNGamePlayScene sceneWithSize:self.frame.size];
  SKTransition *transition = [SKTransition fadeWithDuration:1.0];
  [self.view presentScene:gamePlayScene transition:transition];
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
  TNGamePlayScene *gamePlayScene = [TNGamePlayScene sceneWithSize:self.frame.size];
  SKTransition *transition = [SKTransition fadeWithDuration:1.0];
[self.view presentScene:gamePlayScene transition:transition];
}
@end

I think you will have to put the motion detection method in your view controller, not your scene. SKScene (which inherits from SKNode has touch detection methods, but not motion like shake and what not. So you will have to handle the shake from your view controller
