Is there a way to change the time the iOS keyboard animation takes?
I've actually found a better solution. What you can do is programmatically make the textfield or textview a first responder within an animation with duration of your choice. Example for making the keyboard emerge over the course of one second might be:
[UIView animateWithDuration:1.0 animations:^
{
[myTextField becomeFirstResponder];
}];
Similarly, you can make the keyboard disappear like this:
[UIView animateWithDuration:1.0 animations:^
{
[myTextField resignFirstResponder];
}];
