animated gif - FLAnimatedImage multiple gif playback delay when using loop count - objective c -

i have uipageviewcontroller displays 5 gifs, 1 in each page. flanimatedimage works great, there 1 drawback, there nothing set animation loop , used https://github.com/flipboard/flanimatedimage/pull/60 achieve that.

but problem occurred after gif completes , stops in 1 controller , move controller , return previous controller, gif start after delay.

i'm not sure how fix that. delays in class flanimatedimages related animation delays , not playback delays.

here extract class flanimatedimage.m in method initwithanimatedgifdata:

                // try use unclamped delay time; fall normal delay time.                 nsnumber *delaytime = [framepropertiesgif objectforkey:(id)kcgimagepropertygifunclampeddelaytime];                 if (!delaytime) {                     delaytime = [framepropertiesgif objectforkey:(id)kcgimagepropertygifdelaytime];                 }                 // if don't delay time properties, fall `kdelaytimeintervaldefault` or carry on preceding frame's value.                 const nstimeinterval kdelaytimeintervaldefault = 0.1;                 if (!delaytime) {                     if (i == 0) {                         flloginfo(@"falling default delay time first frame %@ because none found in gif properties %@", frameimage, frameproperties);                         delaytime = @(kdelaytimeintervaldefault);                     } else {                         flloginfo(@"falling preceding delay time frame %zu %@ because none found in gif properties %@", i, frameimage, frameproperties);                         delaytime = delaytimesmutable[i - 1];                     }                 }                 // support frame delays low `kdelaytimeintervalminimum`, below being rounded `kdelaytimeintervaldefault` legacy compatibility.                 // how fastest browsers per 2012: http://nullsleep.tumblr.com/post/16524517190/animated-gif-minimum-frame-delay-browser-compatibility                 const nstimeinterval kdelaytimeintervalminimum = 0.02;                 // support minimum when rounding errors occur, use epsilon when comparing. downcast float because that's delaytime imageio.                 if ([delaytime floatvalue] < ((float)kdelaytimeintervalminimum - flt_epsilon)) {                     flloginfo(@"rounding frame %zu's `delaytime` %f default %f (minimum supported: %f).", i, [delaytime floatvalue], kdelaytimeintervaldefault, kdelaytimeintervalminimum);                     delaytime = @(kdelaytimeintervaldefault);                 }                 delaytimesmutable[i] = delaytime;             } else {                 flloginfo(@"dropping frame %zu because valid `cgimageref` %@ did result in `nil`-`uiimage`.", i, frameimageref);             }             cfrelease(frameimageref);         } else {             flloginfo(@"dropping frame %zu because failed `cgimagesourcecreateimageatindex` image source %@", i, _imagesource);         }     }     _delaytimes = [delaytimesmutable copy];     _framecount = [_delaytimes count]; 

the solution workaround change uipagecontroller transition style curl instead of scroll, new instance of page content controller created , gifs reloaded memory.
