I have a couple of charts on a single page "IOS 7.0.4 / iPhone5" running with data feed in via [selfchart] redrawChart] et al. The page completes and I shutdown the charts thusly:
self.updateChartTimer = nil;
self.chart.delegate = nil;
self.chart.datasource = nil;
self.chart = nil;
self.data = nil;
Then push to the next VC before the ViewDidDisplay completes the App crashes and I get the output:
013-11-16 13:27:45.648 Hipstameter[1223:60b] ShinobiCharts: A datasource has not been set.
From: ShinobiChart at 0x18f9cd10
And this is the stack:
The crash is intermittent, say after running the offending page 3 or 4 times you will be sure to get the crash.
