Stop SKAction that RepeatsForever - Sprite Kit

I want to run two animations on my spriteNode depending on its rotation. If the value is negative run one of the animations, if it's positive run the other. And I managed to do that (kind of) but I have a problem. If Animation1 is running, and zRotation changes to positive, they both run because they are repeating forever. So I did this : 

NSMutableArray *walkingTextures = [NSMutableArray arrayWithCapacity:14];


for (int i = 1; i < 15; i++) {
    NSString *textureName =
    [NSString stringWithFormat:@"character%d", i];
    SKTexture *texture =
    [SKTexture textureWithImageNamed:textureName];
    [walkingTextures addObject:texture];
}

SKAction *spriteAnimation = [SKAction animateWithTextures:Textures timePerFrame:0.04];
    repeatWalkAnimation = [SKAction repeatActionForever:spriteAnimation];
    [sprite runAction:repeatWalkAnimation withKey:@"animation1"];

and then when I want it to stop :

    [self removeActionForKey:@"animation1"];

but it keeps running the action, how can I stop the action, then? Thank you!

Change [self removeActionForKey:@"animation1"]; to [sprite removeActionForKey:@"animation1"]; You will have to maintain a global variable which points to the sprite. – ZeMoon
@akashg You could also name the sprite and then later retrieve it by name from the scene or node that contains it. – Jason Coco
Yes, Jason is right. That will be easier to maintain. – ZeMoon
Thank's a lot!! It works now!! Thank you. – iSLB
@akashg you should type up this as an answer, even tho it's a simple one-liner. Then iSLB can accept it and possibly make it easier for someone to find the solution to a similar issue. – Jason Coco

The method is supposed to be called on the node which the SKAction is running on.

Change 

[self removeActionForKey:@"animation1"];

to 

[sprite removeActionForKey:@"animation1"];
