iOS doesn't allow apps to draw over other apps at all, AFAIK.
- saagarjha 8y ago* In some very specific cases apps can "draw" on top of other apps, namely though the "app extension" mechanism which is completely out-of-process and very tightly controlled (for example, apps have very limited ability to modify the context outside of the "rectangle" they render in).
