39_iOS导航控制器pop方法汇总

1，pop到上一级

 [self.navigationController popViewControllerAnimated:YES];

2，pop到顺数第几级

//返回的顺数第几个VC, 从第0页为根视图
-（void）orderBackToVC:(NSInteger)count {
  NSInteger MaxCount = navi.viewControllers.count;
        if (MaxCount > count && count >= 0) {
            [navi popToViewController:navi.viewControllers[count]
                             animated:YES];
    }
}

3，pop到倒数第几级

//返回的倒数第几个VC, 0为当前页，1为上一页
-（void）orderBackToVC:(NSInteger)count {
  NSInteger MaxCount = navi.viewControllers.count;
        if (MaxCount > count && count >= 0) {
            [navi popToViewController:navi.viewControllers[MaxCount - count]
                             animated:YES];
    }
}

4，pop到指定控制器

//跳转到指定控制器，参数为控制器名称
- (void)backToVCWithName::(NSString *)name{

        for (UIViewController *controller in navi.viewControllers) {
            if ([controller isKindOfClass:[NSClassFromString(name) class]]) {
                [navi popToViewController:controller animated:YES];
                break;
            }
        }   
}

5，pop到指定控制器并传参

//跳转到指定控制器，并传参，刷新数据
   LLXXXcontroller *myControl = nil;
    for (int i = 0; i < self.navigationController.viewControllers.count; i++) {

        CustomViewController *cv = self.navigationController.viewControllers[i];
        if ([cv isKindOfClass:[LLXXXcontroller class]]) {

            myControl = (LLXXXcontroller *)cv;
            break;
        }
    }

    [self.navigationController popToViewController:myControl animated:YES];
   [myControl refreshData];

6，pop到根控制器

[self.navigationControllerpopToRootViewControllerAnimated:YES];
