与iphone中的pushviewcontroller相反的是什么？

Question

我正在开发一个项目,我以下面的方式调用其他viewcontroller: -

AppDelegate *app2 = (AppDelegate *)[[UIApplication sharedApplication]delegate];
[self.navigationController pushViewController:app2.SecondForm animated:NO];
app2 =nil;

我的应用程序是基于导航的,我在导航栏上创建了我的后退按钮

-(void)viewDidLoad
{
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarStyleBlackOpaque target:self action:@selector(Back:)];
}

通过这种方式我的后退动作将调用点击

-(IBAction)Back:(id)sender
{
     // What code I will write over here to get the same functionality
     // which is by default given by navigation controller?
}

我想你正在寻找:

[self.navigationController popViewControllerAnimated:YES];
