How do I find out the current keyboard used on iOS8?

Question

You can get a list of the keyboards installed on the iOS device using:

NSUserDefaults *userDeafaults = [NSUserDefaults standardUserDefaults];
NSDictionary *

@Leo Natan's answers is cool but it's may return nil when the keyboard have not display.

So here I use the string to find the UIKeyboardInputMode's property.

I can tell you that this can find out the current keyboard because it's comes from Apple's Private API.

Code here:

+ (BOOL)isTheCustomKeyboard
{
    UITextInputMode* inputMode = [UITextInputMode currentInputMode];
    if ([inputMode respondsToSelector:NSSelectorFromString(@"identifier")])
    {
        NSString* indentifier = [inputMode performSelector:NSSelectorFromString(@"identifier")];
        if ([indentifier isEqualToString: YOUR_APP_ID])
        {
            return YES;
        }
    }
   return NO;
}

And more:

+ (BOOL)isContaintCustomKeyboard
{
    NSArray * inputModes = [UITextInputMode activeInputModes];
    for (id inputModel in inputModes)
    {
        if ([inputModel respondsToSelector:NSSelectorFromString(@"identifier")])
        {
            NSString* indentifier = [inputModel performSelector:NSSelectorFromString(@"identifier")];
            if ([indentifier isEqualToString: YOUR_APP_ID])
            {
                return YES;
            }
        }
    }
    return NO;
}

Actually we can also use the displayName or the identifier and more.
