iPhone SDK: TextView, Keyboard in Landscape mode
- by Arnold
Hello.
How do I make sure that the textview is shown and the keyboard is not obscuring the textview, while in landscape.
Using UICatalog I created a TextViewController which works. In it there are two methods for calling the keyboard and making sure that textView is positioned above the keyboard. his just works great in Portrait mode.
I got the Landscape mode working, but on the textView is still being put to the top of the iPhone to compensate for the keyboard in portrait mode.
I changed the methods for showing the keyboards.
Below is the code for this methods: (I will just let see the code for show, since the hide code will be the reverse..
- (void)keyboardWillShow:(NSNotification *)aNotification
{
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait) {
// the keyboard is showing so resize the table's height
CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] 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];
} else if (orientation == UIInterfaceOrientationLandscapeLeft) {
NSLog(@"Left"); // Verijderen later
CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue];
NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect frame = self.view.frame;
frame.size.width -= keyboardRect.size.height;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
} else if (orientation == UIInterfaceOrientationLandscapeRight){
NSLog(@"Right"); // verwijderen later.
CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue];
NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect frame = self.view.frame;
frame.size.width -= keyboardRect.size.width;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
}
}
I know that I have to change the line frame.size.height -= keyboardRect.size.height but I do not seem to get it working.
I tried frame.size.width -= keyboardRect.size.height that did not work. Losing the keyboardRect and frame all together work, however off course the keyboard obscures the textview........
