Question

I am very confuse with my small test app.When i do on the Textfield the keyboard comes slowly I want to increase the keyboard time.Can anybody tell me that how i can increase the time of KeyBoard up and down?

Answer 1

The speed of the system keyboard can be retrieved via the UIKeyboardAnimationDurationUserInfoKey and is read-only.

UPDATE: How to get the values. In the notification listener:

- (void)keyboardWillShow:(NSNotification*)notification 
{
    NSDictionary* userInfo = [notification userInfo];
    NSTimeInterval animationDuration;
    UIViewAnimationCurve animationCurve;

    [[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
    [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
}
