Description m 2014-09-12 12:31:13 UTC
On iOS, putting Sliders inside a ListView (wrapped into ViewCells) does not work properly.

a) Sliders inside ListViews don't recognize touch orientation properly if the device is in landscape mode. Essentially the directions are swapped -- vertical gestures can move the horizontal sliders, horizontal gestures cannot. 

b) Sliders inside ListViews don't work on Retina resolutions -- value is set to Minimum if finger moves to the start of the slider; however, it moves twice as fast as it should if the finger moves to the right (and reaches maximum when the finger is at the middle of the slider).

Tested on actual iOS7.1 Retina iPad and on the simulator as well.

Any plans to fix this? Such a trivial bug in the slider implementation should not take half a year to fix..

Does not seem to be an issue on the latest versions of Forms
