ios - Watchkit`s WKInterfaceImage setImage causes "Terminated due to Memory error" -


i want animate images on watch (like activity app, if you´re interested, it´s not important problem)

i draw images in loop first: glancecontroller.m

nsmutablearray *images = [[nsmutablearray alloc] init];       for(int = 0, j = 0; < 10; i++, j++){     @autoreleasepool {         // ...          uigraphicsbeginimagecontextwithoptions(rect.size, no, 0);          // ...           // create uiimage , save array later         uiimage *ejcircle = uigraphicsgetimagefromcurrentimagecontext();          [images addobject: ejcircle];         ejcircle = nil;           uigraphicsendimagecontext();     } }

so far works fine, autoreleaspool, memory consumption not high here, (about 5 mb before autoreleasepool gets drained 2 mb)

however try animate in wkinterfaceimage, memory error:

// take array , create animated image out of uiimage * img = [uiimage animatedimagewithimages:images duration:1.0];  // memory normal 2 mb after line [wkinterfaceimage setimage:img]; // app crashes here // memory consumption jumps 30 mb after line: // watch app, app gets terminated. [wkinterfaceimage startanimatingwithimagesinrange:nsmakerange(0,50) duration: 1.0 repeatcount: 1];

my question is, why app crashes in line. memory consumption explodes, don´t alloc/malloc/new here. don't understand what´s going on, appreciated.

edit: found crash log in xcode devices:
