SpriteKit animateWithTextures non funziona con atlante texture

Question

Quando non uso atlante texture, tutto funziona bene. Ma quando uso atlante texture, animateWithTextures non funziona e non appare nulla. Ecco il mio codice

SKTexture *spaceshipTexture = [SKTexture textureWithImageNamed:@"monkey.png"]; 
SKSpriteNode *spaceship = [SKSpriteNode spriteNodeWithTexture:spaceshipTexture]; 
spaceship.position = CGPointMake(0,0); 
spaceship.anchorPoint = CGPointMake(0,0); 
[self addChild: spaceship]; 

NSMutableArray *images=[NSMutableArray arrayWithCapacity:14]; 
for (int i=1; i<=14; i++) { 
    NSString *fileName=[NSString stringWithFormat:@"%dShuGuangx.png",i]; 
    SKTexture *tempTexture=[SKTexture textureWithImageNamed:fileName]; 
    [images addObject:tempTexture]; 
} 
NSLog(@"count %d",images.count); 
SKAction *walkAnimation = [SKAction animateWithTextures:images timePerFrame:0.1]; 
[spaceship runAction:walkAnimation]; 

Answer 1

[SKTexture preloadTextures:images withCompletionHandler:^(void){ 
     [spaceship runAction:walkAnimation]; 
    }]; 

Questo risolto il mio problema.
