e.jsEvaluationValue is undefined

In my application your package didn't work. When i debugged, i found that param e.jsEvaluationValue was null in method _updateWebViewHeight, maybe because react-native has bug.

Solution

I rewrote the communication between app and webView on postMessage/onMessage. I had problem with a notify through postMessage, but this comment helped me. Maybe you known better solution for it.

It works fine in android ! Even on android 4.4.4.
However in IOS, the height often way too long and creating empty space at bottom.

Solution

One way to fix this was change waitForBridge() to setTimeout(waitForBridge, 200)
And add a defaultHeight in defaultProps to some value much smaller than what your content is.

Thanks @UrbanSam for testing on iOS. If i will set height in defaultProps and change waitForBridge() on setTimeout(waitForBridge, 200), then will this enough? Will it work on iOS?

@dima11221122 Yup at least it works on my simulator. Will let you know if it works in actual device.

@dima11221122 Yup it works fine on my Iphone 5s.
