i adding following in relation comments placed on thread. code main ui related change, other usual label setting etc, can't see issue with.

the code below added appdelegate.m, didfinishlaunchingwithoptions.

i wondering, crash not have been able re-produce, , whilst happening daily in handful of cases, if timing issue, , ui not being available receive messages.

i welcome thoughts, , if agree, if should instead move code viewdidload in viewcontroller instead.

after searching in code, stumbled across post on here objc_msgsend [__nsarraym dealloc] crash report crashlytics.

it seems crashlytics had bug in 3.0.9, , cause of issue.

updated sdk , okay.
