//点击输入框界面跟随键盘上移

• (void)textFieldDidBeginEditing:(UITextField *)textField {

  CGRect frame = textField.frame;
  int offSet = frame.origin.y + 70 - (self.view.frame.size.height - 216.0); //iphone键盘高度为216.iped键盘高度为352
  [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
  [UIView setAnimationDuration:0.5f];
  //将试图的Y坐标向上移动offset个单位，以使线面腾出开的地方用于软键盘的显示
  if (offSet > 0) {
  self.view.frame = CGRectMake(0.0f, -offSet, self.view.frame.size.width, self.view.frame.size.height);
  [UIView commitAnimations];
  }
  }

//输入框编辑完成以后，将视图恢复到原始状态

• (void)textFieldDidEndEditing:(UITextField *)textField {
  self.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
