----------------------------------
Fixed in
https://git-wip-us.apache.org/repos/asf?p=incubator-cordova-ios.git;a=commit;h=e545a4ba974a543fe02b9e3c0ac11c95c9645404
Fix is two fold:
First, onAppDidEnterBackground had to call cordova.fireDocumentEvent('pause',
null, true); <-- needs the two extra parameters to signal fireDocumentEvent to
NOT use setTimeout(..., 0).
Second, added CDVCommandDelegate (void)evalJs:(NSString*)js
scheduledOnRunLoop:(BOOL)scheduledOnRunLoop to be used by both events in order
to process plugin calls from js return value *without* scheduling on run loop.
Together, this makes the resign and pause events run as synchronously as
possible, so as not to give up the process context -- since it would not resume
until app is foregrounded again.
onAppWillResignActive did not need the two extra parameters, because it is not
an officially registered cordova event (is dispatched using
document.dispatchEvent(evt), and that one is not wrapped with a setTimeout --
go figure). I could make resign(and its sibling 'active') an official event
inside common.js but was unable to do so from the ios platform specific js.
Going to file a separate issue for that.. but this works as is.
> IOS events onAppWillResignActive and onAppDidEnterBackground do not execute
> JS until after app is launched again.
