iMessage Style Receding Keyboard in an iOS App

In the iOS5 Messages app, you can slide your finger down on the keyboard to bring it up and down. This is also done in the iA Writer app in the AppStore. How can I do this in code, that is, access and modify the Y position of the UIKeyboard?

Answer 1

Why reinvent the wheel? There are several open-source projects available that mimick the messages.app receding keyboard:

1. http://cocoacontrols.com/platforms/ios/controls/madismissivetextview

2. http://cocoacontrols.com/platforms/ios/controls/dakeyboardcontrol

3. http://cocoacontrols.com/platforms/ios/controls/imessagekeyboardeffect

To name a few.

Answer 2

There is no method to do this, but you may be able to modify the keyboard's frame directly like this:

UIWindow* tempWindow;

//Because we cant get access to the UIKeyboard throught the SDK we will just use UIView. 
//UIKeyboard is a subclass of UIView anyways
UIView* keyboard;

//Check each window in our application
for(int c = 0; c < [[[UIApplication sharedApplication] windows] count]; c ++)
{
    //Get a reference of the current window
    tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:c];

    //Get a reference of the current view 
    for(int i = 0; i < [tempWindow.subviews count]; i++)
    {
        keyboard = [tempWindow.subviews objectAtIndex:i];

        if([[keyboard description] hasPrefix:@"(lessThen)UIKeyboard"] == YES)
        {
            //If we get to this point, then our UIView "keyboard" is referencing our keyboard.
        }
    }
}
