(一)使用NavigationViewController进行页面跳转时,应该使用pushViewController方法来跳转至下一页面。这种话。下一页面相同在NavigationViewController容器中。
1、跳转到下一页面:
PowerViewController *power = [[PowerViewController alloc] init];
//所要跳转页面PowerViewController中有个属性dictionary1是个NSMutableDictionary类型的容器[power.dictionary1
 setObject:[self.outTxtPass text] forKey:ALONE_SITEPRIZE_PWD];//使用pushViewController跳转到下一页面[self.navigationController
 pushViewController:power animated:YES];
//此页面已经存在于self.navigationController.viewControllers中,而且是当前页面的前一页面
PowerViewController
 *power = [self.navigationController.viewControllers objectAtIndex:self.navigationController.viewControllers.count-2];//初始化其属性power.dictionary
 = nil;//传递參数过去power.dictionary
 = [NSMutableDictionary dictionaryWithDictionary:self.dictionary1];//使用popToViewController返回并传值到上一页面[self.navigationController
popToViewController:power
 animated:YES];注意此时应该在viewDidAppear中进行推断并接收传递的值:
-(void)viewDidAppear:(BOOL)animated{  //推断并接收返回的參数}//返回到上一界面-(IBAction)backOff:(id)sender{    [self.navigationController
 popViewControllerAnimated:true];}
(二)关于ios中 viewcontroller的跳转问题。当中有一种方式是採用navigationController pushViewController 的方法,比方我从主页面跳转到了一级页面,又从一级页面跳转到了二级页面。然后从二级页面跳转到了三级页面,依次类推。假设一级一级的返回我知道是没有问题的。调用navigationController popViewControllerAnimated即可了。
可是某些情况下我可能想要立即回到主页面,而不是一级一级的返回(假设有非常多层会非常累的),那该怎么办呢?
1.返回根页面vc用 
[self.navigationController
 popToRootViewController]
2.返回根页面vc用
 :
[self.navigationController
 popToViewController:[self.navigationController.viewControllers objectAtIndex:2] animated:YES];
或(通过class定位)
for
(UIViewController *controller in self.navigationController.viewControllers) {    if
([controller isKindOfClass:[TargetController class]])
 {        [self.navigationController
 popToViewController:controller animated:YES];    }}
