(area used by) Keyboard in iOS 15.x

[Mark Smith]

Thank you Sean and Jacque, 

I’ve not had a chance to work on a complete solution but thought I would make a test run to see what “the effective working screenrect” was returning and as the following indicates, it does in fact take into consideration the keyboard. I just coded up one line to  run whenever the status of the keyboard changed and tried it both with and without the “predictive” option turned on. As you can see, it was very sensitive to this change…

without predictive:

9:37:14 PM keyboardActivated 0,0,375,451
9:37:15 PM keyboardDeactivated 0,0,375,667
9:37:18 PM keyboardActivated 0,0,375,451
9:37:19 PM keyboardDeactivated 0,0,375,667
9:37:19 PM keyboardActivated 0,0,375,451
9:37:23 PM keyboardDeactivated 0,0,375,667


with predictive: 

9:56:54 PM keyboardActivated 0,0,375,407
9:56:55 PM keyboardDeactivated 0,0,375,667
9:56:55 PM keyboardActivated 0,0,375,407
9:56:57 PM keyboardDeactivated 0,0,375,667

In my particular case not all 4 value are immediately useful. For example, I have a fixed header and footer that need to be accommodated so the correct “useable” rect for me is:

0,69, 377, 618 (for no predictive)
0,69,377,456 ( for predictive)

but this can easily be accommodated since the header/footer values don’t change. The beauty is I now have a rect lower bound (ie. keyboard height) that actually reflects where the keyboard is. 

Brilliant!! Thank you both,

Mark

Sean, I tried iPhoneSafeAreaInsets() but it appears it returns a constant set of values regardless of keyboard position on my iPhone 12

11:51:22 AM keyboardActivated 0,47,0,34
11:51:22 AM keyboardDeactivated 0,47,0,34
11:51:26 AM keyboardActivated 0,47,0,34
11:51:26 AM keyboardDeactivated 0,47,0,34

And didn’t change when I added / subtracted “predictive”. So, just the available usable space at the top and bottom of the screen. I haven’t adjusted my app yet to fully take advantage of the larger screen on a 12 (it was developed on a 6S) but when I get to more response design this will be useful to know where the usable top and bottom are. 

Cheers!!
