the effect is different in android and ios

[zhujianyang]

In version 2.6.5, I set up baseURL with MaplyRemoteTileSource and quadImage with MaplyQuadImageTilesLayer

In version 3.2, I set up baseURL with MaplyRemoteTileInfoNew and quadImage with MaplyQuadImageLoader. Caching works, but not to the desired effect

The effect of 3.2 is the same as that of 2.6.5

The ios layer has been loaded in Asia, and when you go to Africa, there will be a blurred mask in Africa, and then the African layer will be loaded, and when you go back to Asia, there will be a blurred mask in Asia.

What I want is that when we go back to Asia, there's no ambiguity

Android version 3.2 won't have this effect

Are you on support?

[zhujianyang]

yes。 I want to know what caused this effect Why have I loaded Asian data，when i go to africa ，then go back to asian。 Why do I need to refresh the data again

[mousebird]

I take that to mean you're not paying for support. This is a free toolkit and we only have a small amount of time for free support.

My suggestion is to look at the AutoTester app for the appropriate platform and try to duplicate the problem in one of those test layers. GeographyClass or Stamen might work. If the problem occurs in those layers, then we may be able to take a look at it. If it doesn't, then it's something unique to your case.
