How to cause a screen transition when an SKSpriteNode is tapped - ios

Question

I am building an iOS application using the spritekit framework, and I am trying to cause the screen to transition over to the next scene when the user taps the "start" button. I am able to get the screen to transition, and load the next scene, but it happens when the user taps ANYWHERE on the screen.I only want this to occur when the user taps the "start" spritenode. I created the start button using SKSpriteNode, and I named it startButton, using the name property.
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
SKAction *doNothing = [SKAction moveByX:0 y:0 duration:0];
if (startButton != nil)
{
[startButton runAction:doNothing completion:^{
SKScene *gamescene = [[GameScene alloc] initWithSize:self.size];
SKTransition *transition = [SKTransition doorsCloseHorizontalWithDuration:0.0];
[self.view presentScene:gamescene transition:transition];
}];
}
}
Thanks!

Instead of
if(startButton != nil){ }
try using this in the touchesBegan method
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if([node.name isEqualTo:#"startButton"]){
//start scene
}
Make sure that you set the name of the start button (label or sprite) like this
start.name = #"startButton";
EDIT:
Dont use
[startButton runAction:doNothing completion:^{
....
}
Instead, just transition right away
if([node.name isEqualTo:#"startButton"]){
SKScene *gamescene = [[GameScene alloc] initWithSize:self.size];
SKTransition *transition = [SKTransition doorsCloseHorizontalWithDuration:0.0];
[self.view presentScene:gamescene transition:transition];
}
