Hi Xu,
Sorry about the inconvenience caused.
We have created a workaround sample to resolve the issue by using CustomRenderer. CustomRenderer is used to represent the SfChart for our own and it need CustomChart to render the chart.
Please download the sample from below location.
Sample: ListViewChart
We have already logged a defect report for the issue "App crashes when using the Chart inside the ListView in iOS" and the fix for the issue is estimated to be available in our Volume 2 Service Pack 1 release, which is scheduled to roll out by the end of this month.
Thanks,
Manivannan.E
