Suggestions for Offline about mapbox-ios-examples HOT 5 OPEN

Great list, thanks, going to implement a few things when I have time ☺️

from mapbox-ios-examples.

Today I could only work on some of these offline features and it's still WIP.
I'm going to work on it as soon as I have time again.

Testing the code you've committed so far, great! Is it a bug that I can re-download the same area over and over? Seems to me, to save bandwidth, the user shouldn't have to re-download the same content twice and should be skipped.

Also downloading a large area, it only downloads 1284 resources before halting. Pausing and Resuming starts the whole thing over. EDIT: Opened mapbox/mapbox-gl-native#6814

Are these mapbox sdk errors?

Sadly I didn't have much time left to work on this repo the last few days.

There is already a mechanism to prevent the user to download the same content over and over again, it just isn't clearly when using my example. When you press download, Mapbox "downloads" the content from the disk and not over network.

Your Mapbox-powered application will reuse tiles and resources that are required by multiple regions, conserving network traffic and disk space.

This is the same as stated above. Pausing and resuming assumes that it downloads the whole thing over but it doesn't. It first "downloads" the content from disk and then starts downloading the remaining tiles over network. (I've read this somewhere sometime but I couldn't find it anymore)

Well, that's how I understood how the whole process works based on the documentation. Maybe @1ec5 can confirm this?

That’s correct. This behavior is documented in the MGLOfflinePack documentation:

When a pack resumes after being suspended, it may begin by iterating over the already downloaded resources. As a result, the progress structure’s countOfResourcesCompleted field may revert to 0 before rapidly returning to the level of progress at the time the pack was suspended.

mapbox/mapbox-gl-native#5808 tracks making this behavior more intuitive.
