I want to show the keyboard up using an Activator Listener (if the phone gets shaken)
How do I call the keyboard using a command?
UIView* view = ...; [view becomeFirstResponder];
or if that fails you could try:
[view performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0];
If you're interested in getting different types of keyboards, you could do something like this beforehand:
UItextField* textField = ...; [textField setKeyboardType:UIKeyboardTypeNumberPad];
