ios - 在自动布局中隐藏不断增长的 UItextview 的键盘。如何克服这一点？
<p><p>我需要在我的应用中实现聊天功能。其中我有一个如图所示的 InputView。</p>

<p>InputView 是带有左右按钮和 TextView 的 <code>蓝色彩色 View </code>。 </p>
<ol>
<li>单击文本字段时，此输入 View 应向上滚动并且键盘应出现。这个 TextView 是一个不断增长的文本字段，其中包含文本数量。</li>
<li>但是当我在文本字段中输入多行时。 InputView 和 Textfield 都在增长，但它在键盘下方略微隐藏，如下所示如何克服它？？？</li>

<pre><code>-(void)viewWillAppear:(BOOL)animated{
;
;
}
- (void)viewWillDisappear:(BOOL)animated {
;
;
}
- (void)registerForKeyboardNotifications
{
[ addObserver:self
selector:@selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification object:nil];
[ addObserver:self
selector:@selector(keyboardWillBeHidden:)
name:UIKeyboardWillHideNotification object:nil];
[ addObserver:self
selector:@selector(keyboardWillBeHidden:)
name:UIKeyboardDidHideNotification object:nil];
}
- (void)deregisterFromKeyboardNotifications {
[ removeObserver:self
name:UIKeyboardDidHideNotification
object:nil];
[ removeObserver:self
name:UIKeyboardWillHideNotification
object:nil];
}
- (void)keyboardWasShown:(NSNotification*)aNotification {
NSDictionary* info = ;
CGSize kbSize = [ CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
self.scrollView.contentInset = contentInsets;
self.scrollView.scrollIndicatorInsets = contentInsets;
// If active text field is hidden by keyboard, scroll it so it's visible
// Your app might not need or want this behavior.
CGRect aRect = self.view.frame;
aRect.size.height -= kbSize.height;
if (!CGRectContainsPoint(aRect, self.inputView.frame.origin) ) {
;
}
;
}
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
self.scrollView.contentInset = contentInsets;
self.scrollView.scrollIndicatorInsets = contentInsets;
;
}
- (void)textViewDidChange:(UITextView *)textView {
CGSize sizeThatShouldFitTheContent = ;
//chatView_heightConstraint is the inputview height
self.chatView_heightConstraint.constant = MIN(sizeThatShouldFitTheContent.height + 8, 87);
CGRect _f = self.textView.frame;
_f.size.height = MIN( self.textView.contentSize.height, 79.0);
self.textView.frame = _f;
}

<p><p>最后我解决了这个问题...在 ScrollView 之后添加了一个 View ，这个技巧奏效了!!! <code>ScrollView --> UIView --> TableView 和 InputView</code></p></p>
