objective c - iOS Low Memory Warning in MapKit/SDWebImage -


i've become frustrated enough beg insights mob. have application using mapkit, on tap shows thumbnail, , on tap of thumbnail shows photo gallery of images. images using sdwebimage. i've looked @ allocation tables , see map alone using ton of memory. peaks @ around 60mbs, kind of crazy. when open gallery drops around 40/35mbs. can @ 1 gallery find, open second gallery , start scrolling crashes, though memory use around 35mbs.

my first attempts @ combating purge webimage cache on didreceivememwarning, second remove map , annotations. app using arc.

here question... how can fix this? stop memory crash. help?

allocation graph allocation graph

allocation table allocation table

i figured out on own. in case 1 else runs i'll explain. solution simple. using cocoapod called uiphotogallery. problem. in causing memory not released. didn't bother trying fix it. instead found 1 worked better. we're using mwphotobrowser (https://github.com/mwaterfall/mwphotobrowser). works charm , wasn't difficult setup.

in case else looking gallery library tried:

  • ios-krimageviewer
  • nimbus
  • gvphotobrowser
  • uiphotogallery

all of either complicated, lacked documentation, or didn't work good. hope helps others.
