关于ios中 viewcontroller的跳转问题,其中有一种方式是采用navigationController pushViewController 的方法,比如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。,如果一级一级的返回我知道是没有问题的.
UIViewController *vc =self.navigationController.viewControllers[1];
[self.navigationController popToViewController:vc animated:YES];
你自己算 你是第几级界面 然后pop回去就可以了
方法二:
UINavigationController *nav = self.navigationController;
NSMutableArray *viewControllers = [[NSMutableArray alloc]init];
for (UIViewController *vc in [nav viewControllers]) {
[viewControllers addObject:vc];
if ([vc isKindOfClass:[youNeedJumpVC class]]) {
break;
}
}
[nav setViewControllers:viewControllers animated:YES];
