IOS关于UIViewController之间的切换

IOS关于UIViewController之间的切换

1.NavigationController切换UIViewController的两种方式

方法一右侧进入

1 SecondViewController* svc=[[SecondViewController alloc]init];

2 [self.navigationController pushViewController:fvc animated:YES];

返回到上一个

[self.navigationController popViewControllerAnimated:YES];

另一种方法从下面切入

SecondViewController* svc=[[SecondViewController alloc]init];

[self.navigationController presentModalViewController:svc animated:YES];

[svc release];

返回到上一个UIViewController

[self.navigationController dismissModalViewControllerAnimated:YES];

2.如果没有导航栏NavigationController的话 也是可以切换的

SecondViewController* svc=[[SecondViewController alloc]init];

[self presentModalViewController:svc animated:YES];

[svc release];

返回到上一个UIViewController

[self dismissModalViewControllerAnimated:YES];
