iOS Question Toolbar button blink with black background

Hi Everyone,

Just want to ask regarding Toobar bar button on Erel's Coordinate Calc app. Everytime I go to next page or hit a back button to go back to main screen, there is a black background button appeared or blink. It is normal or it just on my phone?

It also same when I test Klaus's iSQLiteLight3 app.

Is it a way to disable this 'black background' from appeared?

Please test it with the latest online version: https://itunes.apple.com/us/app/b4i-coordinates-calculator/id915366768?mt=8

I don't see any black background. Do you see it?

I'm already with the latest online version. When I hit 'Realtime' bar button, there are black background for SMS and Email button appear for a split second while loading the page.

Attached is a capture of screen when I touch back button. During transition to open the main page, it will 'blink' the bar button with black background.

Try to set the translucent property of the bar to false: https://www.b4x.com/android/forum/threads/change-top-and-bottom-bars-color.48071/#post-299497
