Actually it is not my case. Few of my customer experienced. Picker view has 2 buttons "Done" and "Cancel". When user press Done or Cancel, a gray rounded rect popup view(with text "Done" or "Cancel" which user pressed) appeared and disappeared soon like toast message. In "Cancel" button has only dismiss dialog only. I cannot reproduce that in my iPhone. Only few users experienced this. How can I fix this issue? Is it depends on settings or something?
