  @property (nonatomic, assign) BOOL keyboardChangeFollowed;
  
  /// default is NO. if the view becomes first responder，you need set YES to keep the animation consistent
  @property (nonatomic, assign) BOOL becomeFirstResponded;

  _popupController.becomeFirstResponded = YES;
  _popupController.keyboardChangeFollowed = YES;
  _popupController.willPresentBlock = ^(zhPopupController * _Nonnull popupController) {
  	[textField becomeFirstResponder];
  };
