Show iPhone keyboard programmatically

I want show the iphone keyboard. Ho开发者_如何转开发w can I write the code (programmatically) to show the keyboard.

As Jacob said, you'll have to run becomeFirstResponder on a UITextView to make it the first responder, the object the user's currently working with. If you do this, the iPhone OS automatically shows the keyboard, cause that's what's needed for working with a UITextView from a user perspective.

As others have noted, you send the becomeFirstResponder message to the control that you want the keyboard to edit.

One extra thing you should be aware of is that if you plug an external keyboard into an iPad then the keyboard will not appear on screen. You need to design your view so it doesn't look silly without the on-screen keyboard.
