I have a UITableview with a UISearchBar, which contain Japanese words, and I want to test if it works to search Japanese words with Japanese keyboard. I can\'t find how to c
I think what we really want to do is add an international keyboard, not change the language of the simulator.
Open on simulator Settings application ->General->International->Language. Select here your language and keyboard will have required letters.
Note that for Japanese (and Chinese) the keyboard layout isn't that important; what is needed is an input module converting the input to actual ideographic characters. Those are called "IME" (Input Method Editor)
A keyboard has just about a hundred keys, only half of them being alphabetic; but Japanese and Chinese need several thousands different characters. The role of IMEs are to convert phonetic of descriptive input into the wanted characters. Japanese keyboard provides direct typing of phonetic japanese characters (katakana and hiragana); but all japanese IMEs acccept phonetic input either in native kana or in romanized (in latin letters).
