iphone - iOS app memory increases on loading image (5 MB) on image view -


i trying load image (5.4 mb) of resolution 4923 x 9405 on image view. there drastic increase in memory allocation of app load image. memory allocation before loading image around 17 mb, whereas reaches 198 mb when load image on image view. assuming app should consume memory of 5 mb while loading image proved wrong when analysed memory allocations of app.

my questions

  • why ios app shows such behaviour?
  • is there way identify, actual memory allocation of app when such large images loaded?

you can check attached screenshots memory allocations before loading image , after loading image.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
