Question

I have an App I am developing for iOS, and the app does the following

Load and set annotations and launch corelocation and zoom to location.

There are a lot of annotations on the map, the loading from data doesn’t take long, but the actual rendering of them them to the map takes a while.. so the user interface sort of stalls for a little bit, and then finally gets the corelocation and zooms to it.

While this is functional, it is less than ideal user experience.. I could invert the order, than do the corelocation zoom first and then call the add annotations, but this would cause a pause to the UI as well since annotations are added in the UI thread, and not to mention that corelocation could take a little time to get its location first too.

So, the question I guess I am asking is what is the best way to handle this? Is there some way I am unaware of to have the annotations render to the map without tying up the UI? I could show some sort of Splash Screen I guess over the map while this is going on, but that seems a cop out, and I personally hate splash screens.

Maybe the best way to do this is to show the BUSY/WORKING spinner over the map until its completed?

What is generally considered best practice?

Answer 1

I wound up simply doing the same thing I did with the android version, while iphone can handle the larger number of annotations far better than droid, the lazy loading approach certainly is a better overall experience for both platforms.

Thanks for the help guys.
