IOS 初学笔记 之 页面之间跳转方式

//跳转指定页面- (IBAction)zhiding:(id)sender {    [self.navigationController popToViewController:self.navigationController.childViewControllers[1] animated:YES];}//跳转到根控制器- (IBAction)gen:(id)sender {    [self.navigationController popToRootViewControllerAnimated:YES];}//返回上一级- (IBAction)shangyiji:(id)sender {    [self.navigationController popViewControllerAnimated:YES];}

例子
点击跳转事件-(void)aclick:(UIButton *)btn{    DdiscountssViewController *towVC=[[DdiscountssViewControlleralloc] init];    towVC.hidesBottomBarWhenPushed=YES;    [self.navigationControllerpushViewController:towVCanimated:YES];}
