There is a memory leak in the program

[zsf1975]

Please forgive me for my English level. I found that xcode instruments reported multiple memory leaks in my program, and 48 memory leaks in the kivy touchtracer example, and no leaks after the program started 20 seconds later. I'm a kivy beginner, and I don't know if this is sdl2 2.0.9, python-specific garbage collection or other code problems. I'm concerned that this issue will affect the program's submission to the app store. I use kivy 2.0 rc, xcode 11, ios version 12-13.3.
In addition, each time the program starts, the program always outputs Unbalanced calls to begin/end appearance transitions SDL_uikitviewcontroller: 0x113de0cc.
Thanks for such a great program.

Did you find a solution for the "Unbalanced calls" problem? I am currently getting the same thing happening to me.

hi， I can't remember, it seems that it is not a bug, but a memory management problem in the early version of ios 12. The test is normal in the ios 11 series version. In addition, kivy has a caching mechanism for the release of image resources. However, for programs that frequently change images, this caching mechanism slows down the time to release memory, resulting in increasing memory requirements. I only remember this, and I hope it can help you.
