Question: I am developing a game having a scroll view which contains image buttons(Images in drawable are being used not from server), I got `Out Of Memory` error and to deal with `OOM` error I referred this [answer](https://stackoverflow.com/a/10127787),in which the image was scaled down to reduce memory but this is reducing my image quality to a great extent,

So my question is, How to solve OOM issue for Android App without reducing the image quality?

Answer: 
Check the source code for storyboard by right clicking MyStoryBoard->Open As->Source Code.

Search for :`trigger="accessoryAction"` 
If you find it , delete it.

Sometime ctrl+dragging adds this additional attribute causing issues with prepareForSegue.
Okay, I found my problem. I had accidentally created a new instance of the original UIViewController. So even though the functions were calling, it was not referencing the viewController on screen.
