切換UIViewController的兩種方式

1. 有NavigationController時

方法一：右側進入

SecondViewController* svc=[[SecondViewController alloc]init];
[self.navigationController pushViewController:svc animated:YES];

返回到上一頁

[self.navigationController popViewControllerAnimated:YES];

方法二：下面切入

SecondViewController* svc=[[SecondViewController alloc]init];
[self.navigationController presentModalViewController:svc animated:YES];

返回到上一個UIViewController

[self.navigationController dismissModalViewControllerAnimated:YES];

2、没有NavigationController的切換方法

SecondViewController* svc=[[SecondViewController alloc]init];
[self presentModalViewController:svc animated:YES];

返回到上一個UIViewController

[self dismissModalViewControllerAnimated:YES];

取得子viewController或父ViewController的方式

假設View A是來源的ViewController，而View B是目標ViewController。
1.取得子viewController

((B *)self.presentedViewController).屬性名

2.取得父viewController

((A *)self.presentingViewController).屬性名

其中括號和類名是一種強制轉類型的用法。
