Some times, while you try to enter the text in text field's , you might not be able to see the text which you are typing in the text box. It get hide with the popup keyboard. If you don't want to hide the text box while typing, just add the below 2 functions in your code.
- (void)keyboardWasShown:(NSNotification *)aNotification {
if ( keyboardShown )
return;
if( textView.text != 0 ) {
NSDictionary *info = [aNotification userInfo];
NSValue *aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
NSTimeInterval animationDuration = 0.300000011920929;
CGRect frame = self.view.frame;
frame.origin.y -= keyboardSize.height-44;
frame.size.height += keyboardSize.height-44;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
viewMoved = YES;
}
keyboardShown = YES;
}
- (void)keyboardWasHidden:(NSNotification *)aNotification {
if ( viewMoved ) {
NSDictionary *info = [aNotification userInfo];
NSValue *aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
NSTimeInterval animationDuration = 0.300000011920929;
CGRect frame = self.view.frame;
frame.origin.y += keyboardSize.height-44;
frame.size.height -= keyboardSize.height-44;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
viewMoved = NO;
}
keyboardShown = NO;
}
Observe the screen shots below before and after the code:
 |
| Actual screen before typing |
 |
| While typing, entire screen will be moved to upwards |
Pleaes let me know if you have any questions or concerns.
Happy coding :)
