取得使用者目前鍵盤/輸入法

目前用不上，還是備忘一下

NSUserDefaults* defs = [NSUserDefaults standardUserDefaults];
NSArray* languages = [defs objectForKey:@"AppleLanguages"];
NSString* preferredLang = [languages objectAtIndex:0];

不確定這作法抓到的是什麼就是了..


此外也可以監視使用者切換事件
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(inputModeDidChange:)
name:@"UIKeyboardCurrentInputModeDidChangeNotification"
object:nil];

- (void)inputModeDidChange:(NSNotification*)notification
{
id obj = [notification object];
if ([obj respondsToSelector:@selector(inputModeLastUsedPreference)]) {
id mode = [obj performSelector:@selector(inputModeLastUsedPreference)];
NSLog(@"mode: %@", mode);
}
}
