I've an app that should show a 3D model, at this point all is OK, but this model rotates in all 3D space axis and I need that this model rotate only on X axis (left/right) when user tries rotate the model.
Any idea? I've been stuck here for a while...
Provide your own camera. Don't use the "allows camera control" checkbox in Interface Builder, and leave the view's allowsCameraControl property set to false.
You said "X axis (left/right)". But in SceneKit, the X axis runs left to right, so rotating left/right is a rotation around the Y axis. Add a swipe gesture recognizer to recognize swipes left and right. Use the recognizer's handler to rotate your model around the Y axis as the user's finger slides left and right.
