CPTestApp for iPad crashes in simulator iOS 4.2 #233

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The CPTestApp-iPad is crashing at launch on the iOS 4.2 simulator.
Here is what I get:

terminate called after throwing an instance of 'NSException'

A NaN is being returned by the cache when asking for a double value in the 
CPPieChart when positioning labels.

There's a NAN in the data to test the missing data code. From the stack trace, 
it looks like Core Plot made a label for the missing point and crashed when it 
tried to position the label.

I'm using XCode 4.0.1, and when I run the CPTestApp for iPad on iOS 4.2 
Simulator, I still get this error. I have made no changes to the project.

Never mind. I am using version 0.2.2 (the latest downloadable), and apparently 
this change was made to the trunk. I'll try to sync the source changes directly.
