I have been testing an app on 3 iPads with iOS 8 and I found a bad performance with Ionic Keyboard Plugin. I have reinstalled it 3 times with the same issue.
When running the app in Xcode I get this output in the console:
2014-12-11 10:41:45.388 SGMDealerReview[368:719658] -[UIWebView setHackishlyHidesInputAccessoryView:]: unrecognized selector sent to instance 0x17d68e70
2014-12-11 10:41:45.390 SGMDealerReview[368:719658] *** WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener: delegate: <NSInvalidArgumentException> -[UIWebView setHackishlyHidesInputAccessoryView:]: unrecognized selector sent to instance 0x17d68e70
Then when I type something in an input text, it freezes about 4 seconds and then start typing.
The iPad’s memory increases drastically on keydown (seen in Xcode too).
I created a thin version of my app leaving only the login page and the same result came up with the keyboard.
You open Xcode.
Click on “Show Project Navigator” and click on the target Project.
Then click on “Build Phases”.
Click on “Compile Sources”.
Click on the “Plus (+)”, search for “UIWebViewExtension.m” and add it.
