RegisterViewController *registerViewController = [RegisterViewController new];
[self.NavigationController pushViewController:registerViewController animated:YES];
//返回到根视图
[self.navigationController popToRootViewControllerAnimated:YES];
//返回到指定视图
for (UIViewController *controller in self.navigationController.viewControllers) {
if ([controller isKindOfClass:[LoginViewController class]]) {
[self.navigationController popToViewController:controller animated:YES];
}
}
这种采用压栈和出栈进行页面跳转的方式，就是出入栈跳转。
SelectViewController * selectViewController = [[SelectViewController alloc] init];
//把当前控制器作为背景
self.definesPresentationContext = YES;
//设置模态视图弹出样式
selectViewController.modalPresentationStyle = UIModalPresentationOverFullScreen;
[self presentViewController:selectViewController animated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:NULL];
模态跳转主要在：收集用户输入信息，临时展示一些内容，显示一个新的view层级等时候会用到。
