Show iPhone soft keyboard even though a hardware keyboard is connected

My iPad app uses an external "devi开发者_如何学运维ce" that acts as a hardware keyboard. But, at some point in the settings, I need to input text and I can't use the "device" ("device" is not a keyboard). So, is there any way to force pop the soft keyboard even thought I have a hardware keyboard connected?

Yes. We've done this in a few of our apps for when the user has a Bluetooth scanner "keyboard" paired with the device. What you can do is make sure your textField has an inputAccessoryView and then force the frame of the inputAccessoryView yourself. This will cause the keyboard to display on screen.

We added the following two functions to our AppDelegate. The 'inputAccessoryView' variable is a UIView* we have declared in our app delegate:

//This function responds to all textFieldBegan editing
// we need to add an accessory view and use that to force the keyboards frame
// this way the keyboard appears when the scanner is attached
-(void) textFieldBegan: (NSNotification *) theNotification
{
    UITextField *theTextField = [theNotification object];
    //  NSLog(@"textFieldBegan: %@", theTextField);

    if (!inputAccessoryView) {
        inputAccessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, navigationController.view.frame.size.width, 1)];
    }

    theTextField.inputAccessoryView = inputAccessoryView;

    [self performSelector:@selector(forceKeyboard) withObject:nil afterDelay:0];
}

//Change the inputAccessoryView frame - this is correct for portrait, use a different
// frame for landscape
-(void) forceKeyboard
{
    inputAccessoryView.superview.frame = CGRectMake(0, 759, 768, 265);
}

Then in our applicationDidFinishLaunching we added this notification observer so we would get an event anytime a text field began editing

    //Setup the textFieldNotifications
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textFieldBegan:) name:UITextFieldTextDidBeginEditingNotification object:nil];

Hope that helps!

There’s no way to do this with the current SDK. Please let Apple know via the Bug Reporter.

The solutions here didn't work on iOS 13 or aren't App Store compatible so I solved the problem by creating my own soft keyboard. It is pretty basic but works. Feel free to contribute!

Project on Github

All you have to do is add SoftKeyboardView.swift to your project and somewhere (e.g. appDidFinishLaunching) hit the singleton:

Usage:

SoftKeyboardManager.shared.disabled = false

Since I have the same problem, the closest solution I have found is to use Erica Sadun's app called KeysPlease which is available via cydia and modmyi. It's description is "Use soft kb even when connected to a BT kb.".

Additionally I have found that if you have a physical keyboard also attached, in my case via the iPad keyboard doc, you can bring up the keyboard using a key which seems to map to the eject key on a bluetooth keyboard. Perhaps there is a way to inject this key as if it was pressed on an attached keyboard?

I really wish there was a more official coding solution to this.

When my app connect bluetooth device, keyboard wouldn't show.I try set force the frame of the inputAccessoryView as Brian Robbins say. It didn't work.

Then I use a stupid way to solve.I found when I click textfield or textview one more time, keyboard will show. So I just need to simulate touch in textfield or textview once , it works.
