This question already has an answer here: Scenekit shape between 4 points 1 answer Similar to some of the measuring apps you can see being demonstrated in ARKit, I have a plane with 2 marker nodes on it and a line drawn between the 2. What I need though is an SCNPlane between the 2. So, if your original was the floor and you put a marker either side of a wall, you could represent the physical wall with a SCNPlane in your AR world.

I'm trying to save image to Photos app on iOS 10 and 11 versions. Therefore on iOS 11 I need to request NSPhotoLibraryAddUsageDescription permission, on iOS 10 NSPhotoLibraryUsageDescription .

Does anybody know how to deal with these permissions? 来源： https://stackoverflow.com

Basically I am using Admob to show banner ads and interstitial ads in my iOS app. These have been running in the live app for over a year, they are still currently running live in iOS 10 devices and earlier versions of iOS, without any problems .
