Is there an ActivityIndicator in WatchKit for Apple Watch?

Question

Is there an ActivityIndicator (or something like it) in WatchKit for Apple Watch? How do you all give the user feedback about some longer lasting background activity?

Answer 1

In my opinion, trying to create your own Spinner is using excessive resources. If Apple thought it was a good idea, they would have suggested it.

I would instead just have an Image that you adjust the Alpha. Use a boolean to see if you should be adding or subtracting Alpha.

if (add)
    {
        count=count+5;
        if (count==100)
        {
            add=false;
        }
    }
    else
    {
        count=count-5;
        if (count==0)
        {
            add=true;
        }
    }

    float thealpha=((float)count/100);
    [self.scanb setAlpha:thealpha];

}
