在iOS中旋轉時調整UITextView的大小

您好，我面臨UITextView的問題。在iOS中旋轉時調整UITextView的大小

在我的應用程序中，我需要支持縱向和橫向。

，所以我說UITextView到我的應用程序和調整的UITextView幀時下面的代碼鍵盤出現，因爲當鍵盤出現時，UITextView是鍵盤後面，我看不到我在寫UITextView。

- (void)keyboardWillShow:(NSNotification*)notification 
{ 
    [self moveTextViewForKeyboard:notification up:YES]; 
} 

- (void)keyboardWillHide:(NSNotification*)notification 
{ 
    [self moveTextViewForKeyboard:notification up:NO]; 
} 

- (void)moveTextViewForKeyboard:(NSNotification*)notification up:(BOOL)up { 
    NSDictionary *userInfo = [notification userInfo]; 
    NSTimeInterval animationDuration; 
    UIViewAnimationCurve animationCurve; 
    CGRect keyboardRect; 

    [[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve]; 
    animationDuration = [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]; 
    keyboardRect = [[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue]; 
    keyboardRect = [self.view convertRect:keyboardRect fromView:nil]; 

    [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; 
    [UIView setAnimationDuration:animationDuration]; 
    [UIView setAnimationCurve:animationCurve]; 

    if (up == YES) 
    { 
     CGFloat keyboardTop = keyboardRect.origin.y; 
     CGRect newTextViewFrame = self.txtView.frame; 
     newTextViewFrame.size.height = keyboardTop - self.txtView.frame.origin.y - 10; 
     self.txtView.frame = newTextViewFrame; 
    } 

    else 
    { 
     self.txtView.frame = originalCGRect; 
    } 

    [UIView commitAnimations]; 
}

當鍵盤出現並且不再覆蓋我的UITextView時，這很好。但是，當我旋轉到風景，UITextView框架是不正確了，也當我隱藏鍵盤時，它仍然保持像小尺寸，而不是適合視圖。
