带完成块的动作动画（Plist）

Question

无法在完成时播放动画

触摸，快乐动画应播放 - 当动画完成时，它应该返回空闲动画 （但是在快乐动画完成后没有任何反应）

  if ([touchedNode.name isEqualToString:@"myMonster"]) {

        id callHappy= [SKAction performSelector:@selector (playHappy) onTarget:self];
        id callIdle = [SKAction performSelector:@selector (ReturnToIdleAnimation) onTarget:self];
        NSArray *actionsequence = @[callHappy,callIdle];
        SKAction *allActions= [SKAction sequence:actionsequence];

        [myMonster runAction:allActions completion:^{
        NSLog(@"myMonster Action Complete");
       // [self ReturnToIdleAnimation];

        //*** [self PlayIdleAnimation];*** works
        // but am interested as to why is doesn't get called on the main game layer???


        }];
    }
}

-(void)ReturnToIdleAnimation
{
    [myMonster removeAllActions];
     NSLog(@"ReturnToIdleAnimation");
     [myMonster PlayIdleAnimation];
}

-(void)playHappy
{
     NSLog(@"playHappyAnimation");
     [myMonster PlayHappyAnimation];
}
