We receive some reports for crashes in UIWebSelectSinglePicker
. We guess it's due to an empty datasource array. This occurs in a webview though. How can we work around this? would prefer a native only solution
edit
happens only on iphones, running both iOS7 and iOS8

I would guess this is related to another issue here on SO
There is an issue with the WebView and system controls triggered from HTML.
