Hello, everyone. This is part of my code. After I loaded multiple gifs and then removed them by loopingGifs.remove(), I found that the memory did not decrease. When I used many gifs, there was an error of no memory.Is there any good way to solve this problem？

try to overwrite them instead of adding and erasing the previous. If that doesn’t work, increase the allocated memory in preferences.

Thank you for your answer, but the workload of overwrite will be very large, and I need to rewrite most of the code.Increasing the entire memory is probably not a good idea, because I deleted it soon after it was created but the memory is still increasing
