Keyboard sometimes blocks UITextView - ios

Question

In my app I have a UITextView that is in the bottom part of the screen. So what I do is the following code but the issue is, only sometimes if the text that I click on the UITextView is below the keyboard, it will scroll properly to above the keyboard.
Here is how I register the NSNotifications:
(In the ViewDidLoad)
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasHidden:)
name:UIKeyboardWillHideNotification object:nil];
The methods:
-(void)keyboardWasShown:(NSNotification*)aNotification {
NSDictionary *info = [aNotification userInfo];
// Get the size of the keyboard.
NSValue *aValue = [info objectForKey:UIKeyboardFrameBeginUserInfoKey];
keyboardSize = [aValue CGRectValue].size;
// Resize the scroll view (which is the root view of the window)
CGRect viewFrame = [textView frame];
viewFrame.size.height -= keyboardSize.height;
textView.frame = viewFrame;
// Scroll the active text field into view.
//CGRect textFieldRect = [activeField frame];
[textView scrollRectToVisible:viewFrame animated:YES];
}
-(void)keyboardWasHidden:(NSNotification*)aNotification {
// Reset the height of the scroll view to its original value
CGRect viewFrame = [textView frame];
viewFrame.size.height += keyboardSize.height;
textView.frame = viewFrame;
}
How I unregister the NSNotifications:
In the ViewDidUnload:
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
Does anyone see anything wrong?
Thanks!

Answer 1

here is the code I use to move the textview up so I can see it when the KB shows up. my view is in a scrollview already.
-(void)textViewDidBeginEditing:(UITextView *)textView { //Keyboard becomes visible
//perform actions.
NSLog(#"IN VIEW");
[self scrollTheViewToTop:self.scroller forTheTextView:textView];
}
- (void)textViewDidEndEditing:(UITextView *)textView {
[self.scroller setContentOffset:CGPointZero animated:YES];
}
- (void)scrollTheViewToTop:(UIScrollView *)scrollView forTheTextView:(UITextView *)textView {
//Scroll the ScrollView Up tp show the Continue button in the bottom is visible.
CGPoint pt;
CGRect rc = [textView bounds];
rc = [textView convertRect:rc toView:scrollView];
pt = rc.origin;
pt.x = 0;
pt.y -= 60;
[scrollView setContentOffset:pt animated:YES];
}
