sprite-kit - Set minimum duration for Sprite Kit action

Question

I have implemented the following method in my Sprite Kit Game:

-(void) sprayWater{  
    [self runAction:[SKAction repeatActionForever:[SKAction animateWithTextures:self.runWasserFrames timePerFrame:0.05 resize:YES restore:YES]] withKey:@"water"];    
}

What ist the most elegant way to set the minimum time of this action to 1,5 seconds? I tried several ways, but they did not work out for me so far.

如果我正确理解了这个问题，你应该尝试这样的事情：

-(void) sprayWater
{  

        if ([self actionForKey:@"water"] == nil)
        {
             [self runAction:[SKAction repeatActionForever:[SKAction animateWithTextures:self.runWasserFrames timePerFrame:0.05 resize:YES restore:YES]] withKey:@"water"];   
        } 
}

逻辑是如果水已经在流，不要创建另一个动作。
