找到好久才找到这个效果。

翻转动画
1.建立两个视图,hidden是yes和no
2.将视图加在view上,给按钮一个属性,

• (void)BtnAction:(UIButton *)btn{

  //
  UIView *rightView = self.navigationItem.rightBarButtonItem.customView;
  //
  UIButton *btn1 = (UIButton *)[rightView viewWithTag:100];

  UIButton *btn2 = (UIButton *)[rightView viewWithTag:101];

  UIViewAnimationTransition transframe = btn2.hidden?
  UIViewAnimationTransitionFlipFromLeft:
  UIViewAnimationTransitionFlipFromRight;

  [self _transView:transframe WithView:rightView];
  [UIView commitAnimations];
  btn1.hidden = !btn1.hidden;
  btn2.hidden = !btn2.hidden;
  //

[self _transView:transframe WithView:self.view];//视图翻转和按钮公用一个方式

_tableview.hidden = !_tableview.hidden;
_postview.hidden = !_postview.hidden;

}

• (void)_transView:(UIViewAnimationTransition )trans WithView:(UIView *)view{

  [UIView beginAnimations:nil context:nil];
  [UIView setAnimationDuration:1 ];
  [UIView setAnimationTransition:trans
  forView:view
  cache:YES];

[UIView commitAnimations];

}
