can 1 please let me know how can resolve memory issues , can show images @ same time 100 buttons?

i have tried put uiiamgeview instead of uibutton , have tried use

 dispatch_queue_t queue = dispatch_get_global_queue(dispatch_queue_priority_default, 0ul);         dispatch_async(queue, ^{             // perform non main thread operation             (businessownerentity *busowner in arrbusowner) {                 nsurl *url = [nsurl urlwithstring:busowner.whitelargelogourl];                  sdwebimagemanager *manager = [sdwebimagemanager sharedmanager];                  [manager downloadimagewithurl:url options:sdwebimageprogressivedownload progress:^(nsinteger receivedsize, nsinteger expectedsize) {                      nslog(@"recieved file %ld",(long)receivedsize);                  } completed:^(uiimage *image, nserror *error, sdimagecachetype cachetype, bool finished, nsurl *imageurl) {                  }];             }             dispatch_sync(dispatch_get_main_queue(), ^{                 // perform main thread operation             });         }); 

to download images before crashes here too..

use sdwebimage callbacks load images in queue, not @ same time.
reduce memory consumption , avoid ios kill app.

[manager downloadimagewithurl:url options:sdwebimageprogressivedownload progress:^(nsinteger receivedsize, nsinteger expectedsize) {                  nslog(@"recieved file %ld",(long)receivedsize);              } completed:^(uiimage *image, nserror *error, sdimagecachetype cachetype, bool finished, nsurl *imageurl) {                        if ("are less 10 images loading?"){                           [self startnewimageloading];                        }             }];
