ios keyBoardShow 与 UITableView

Question

在我的代码中，每次弹出键盘时，tableView 都会向上推，所以我可以看到 tableView 的底部。但是前三个或四个单元格将隐藏在视图后面。键盘退出时，scrollView 的顶部似乎被剪切了。

我怎样才能让我的表格视图在发短信时完整查看？

这是我的代码...

-(void)viewWillAppear:(BOOL)animated{
  [super viewWillAppear:animated]; 
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardShow:) name:UIKeyboardWillShowNotification object:nil];
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardHide:) name:UIKeyboardWillHideNotification object:nil];
}
-(void)keyboardShow:(NSNotification *)note{
  CGRect keyBoardRect=[note.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
  CGFloat deltaY=keyBoardRect.size.height;

  [UIView animateWithDuration:[note.userInfo[UIKeyboardAnimationDurationUserInfoKey] floatValue] animations:^{
  self.view.transform=CGAffineTransformMakeTranslation(0, -deltaY);
  }];
}
-(void)keyboardHide:(NSNotification *)note{
  [UIView animateWithDuration:[note.userInfo[UIKeyboardAnimationDurationUserInfoKey] floatValue] animations:^{
    self.view.transform = CGAffineTransformIdentity;
  }];
}

向单元格添加文本后滚动到底部。

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:(self.data.count-1) inSection:0];
[self.tableView beginUpdates];
[self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationRight];
[self.tableView endUpdates];
[self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];

与其在键盘显示时变换视图，不如通过调整其框架来缩小它：

CGRect newFrame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height-deltaY);
self.view.frame = newFrame;
