My iPhone app can’t seem to use soft keyboards that doesn’t use the US-like

  • 0

My iPhone app can’t seem to use soft keyboards that doesn’t use the US-like QWERTY layout. That is when I set the keyboard to French or Germany, even text fields cannot take in text and an error message No input manager class for input mode error is shown in the console (when debugged under Xcode). Switching to the Emoji keyboard also shows the same problem. But the problem doesn’t occur on QWERTY keyboard layouts, like Dutch and Indonesian keyboards.

The all cases are consistent and reproducible both the device (iPhone 4) and the iPhone simulator.
These are error messages in the Xcode’s debugger console

When the keyboard is set to French:

No input manager class for input mode: fr_FR

When the keyboard is set to Germany:

No input manager class for input mode: de_DE

When the keyboard is set to Emoji:

No input manager class for input mode: emoji

My app’s deployment target is iOS 3.1.3 (I’m still supporting 1st gen devices) but the development environment is Xcode 4.3.1 and iOS 5.1 Simulator. (I don’t know whether this is relevant but just in case).

Anybody can help how to fix this?

Thanks in advance.

    In my case, this was caused by my swizzling -[NSBundle infoDictionary] and returning a copy of the original dictionary.

    I did this to be able to change info dictionary values at runtime (specifically, providing a non-shortened bundle display name to replace the shortened value used on the home screen).

    The fix was to not return a copy of the info dictionary, but with some more reflection magic handle each key obtained from the dictionary:
