Hi friends,
This informs you how to use UIKeyboardNotification into your project. By using this , you can make your custom animation at the time of keyboard appears/disappears.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardHide:)
name:UIKeyboardWillHideNotification
object:nil];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIKeyboardWillHideNotification
object:nil];
}
- (void)keyboardShow:(NSNotification *)aNotification
{
// the keyboard is showing so resize the table's height
CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
NSTimeInterval animationDuration =
[[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect frame = self.view.frame;
frame.size.height -= keyboardRect.size.height;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
}
- (void)keyboardHide:(NSNotification *)aNotification
{
// the keyboard is hiding reset the table's height
CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
NSTimeInterval animationDuration =
[[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect frame = self.view.frame;
frame.size.height += keyboardRect.size.height;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
}
If any one has query then place you it over here.
Thanks and Regards,
