iOS MapBox可以在.mbtiles中使用矩形离线地图吗？

I'm trying to make an offline map using iOS MapBox SDK. It's easy to make square map (eg. 32x32 tiles) but for some reason it doesn't work when I try to make rectangle map (eg. 40x32 tiles). It loads but it shows only a small portion of the map or skips some tiles. It just doesn't look as it should. I'm trying to make an offline map using iOS Map
