Change Keyboard Layout/Language

stephen

after searching around.. even using objC thesebare your options to programatically change keyboard type on UITextfield..

typedef enum {
    UIKeyboardTypeDefault,                // Default type for the current input method.
    UIKeyboardTypeASCIICapable,           // Displays a keyboard which can enter ASCII characters, non-ASCII keyboards remain active
    UIKeyboardTypeNumbersAndPunctuation,  // Numbers and assorted punctuation.
    UIKeyboardTypeURL,                    // A type optimized for URL entry (shows . / .com prominently).
    UIKeyboardTypeNumberPad,              // A number pad (0-9). Suitable for PIN entry.
    UIKeyboardTypePhonePad,               // A phone pad (1-9, *, 0, #, with letters under the numbers).
    UIKeyboardTypeNamePhonePad,           // A type optimized for entering a person's name or phone number.
    UIKeyboardTypeEmailAddress,           // A type optimized for multiple email address entry (shows space @ . prominently).
    UIKeyboardTypeDecimalPad,             // A number pad including a decimal point
    UIKeyboardTypeTwitter,                // Optimized for entering Twitter messages (shows # and @)
    UIKeyboardTypeWebSearch,              // Optimized for URL and search term entry (shows space and .)

    UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated

} UIKeyboardType;

sorry buddy 😕

brumm

Again thank you.

@brumm Quick and very very dirty script, far from finished, but only to show how it could be possible. Automatic standard keyboard for 1st TextField, and InputView for 2nd one.
Really automatic, nothing to do, ok for lazy guys 🙄 like us
Sorry for my Cyrillic 😂 (characters taken from Russian keyboard)
Please try it and tell me...

brumm

Looks great, спасибо.

cvp

@brumm Never mind. Did you try it? Is something like that (I know that it is not exactly that) you want?

brumm

I thought there is an easy solution, but that is also great, because when you fill the db you don‘t need to change it all the time. Now I‘m missing some keys like space, shift, minus, exclamation mark. Where i can find the right syntax?

cvp

@brumm I'm sure that my script, not initially written for that, can be made easier...
I'll do it if you let me some time

brumm

@cvp That is very kind of you, no hurry. I‘m not started coding. First I will design the Views and database structure.

cvp

@brumm ouf 😅

cvp

@brumm Could you try this new (far from perfect) version and tell me if useful Double_keyboard.py

brumm

Wow! Thank you so much. Looks awesome.
@cvp Btw. would it be okay for you, if I upload my VocabularyTrainer with your code to Github? Or can I put a link to your gist in my future repository?

cvp

@brumm My code is yours, do what you want. 😀

cvp

@brumm Right alignment done in new version of Double_keyboard.py

becomes

cvp

@brumm my script defines as 2nd keyboard a Cyrillic one because my standard keyboard is Latin, but, of course, you could easily do the inverse...

Far away from being finished. Ugly code and only for fixed iPad 768x1024 resolution.
