The correct way to cache an animated image on Apple Watch?

I am developing an Apple watch app, Displaying data using WKInterfaceTable, each row has an animated image (80 frames, 10 sec duration)

I want to animate this image every 10 seconds, but there is a problem, this makes the Watch very laggy when the image ends up animating and starts animating again.

I tried removing the animation to check if the lag issue is causing the issue and the result is YES.

I was looking for solutions to cache image on Apple Watch, I made the following code:

First, lazy loading image from iPhone, create an animated UIImage

- (UIImage *)countDownImage
{
    if (_countDownImage == nil) {
        NSMutableArray *array = [[NSMutableArray alloc] init];
        for (int i=0; i<=79; i++) {
            UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"counteight-%i", i]];
            [array addObject:image];
        }
        _countDownImage = [UIImage animatedImageWithImages:array duration:10.0f];
    }
    return _countDownImage;
}

      

        
        
        
      

    

Second, in my WKInterfaceController which contains the WKInterfaceTable

Add cached image to cache using WKInterfaceDevice

if ([[WKInterfaceDevice currentDevice].cachedImages objectForKey:@"countImage"] == nil) {
    [[WKInterfaceDevice currentDevice] addCachedImage:self.countDownImage name:@"countImage"];
}

      

        
        
        
      

    

Finally, in my RowController, use WKInterfaceImage setImageNamed to set the image that I previously cached

[self.animateImage setImageNamed:@"countImage"];
[self.animateImage startAnimatingWithImagesInRange:NSMakeRange(0, 79) duration:10 repeatCount:0];

      

        
        
        
      

    

It works and the image has been cached (Checked:

[[WKInterfaceDevice currentDevice].cachedImages objectForKey:@"countImage"] 

      

        
        
        
      

    

)

But it still lags very far behind the real Apple Watch device, even the lagger, than the image in the cache is not configured.

I don't know where I am going wrong, can someone give me some advice on how to cache the animated image on the Apple Watch correctly ?

Thank!
