iOS初学者日记－－－－出入栈跳转和模态跳转

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。
