iOS中隐藏UINavigationBar的方法

 

 

[self.navigationController setNavigationBarHidden:YES animated:YES];

 

 

 

从一个Controller跳转到另一个Controller时，一般有以下2种： 
1、利用UINavigationController，调用pushViewController，进行跳转；这种采用压栈和出栈的方式，进行Controller的管理。调用popViewControllerAnimated方法可以返回。 

    PickImageViewController *ickImageViewController = [[PickImageViewController alloc] init]; 
    [self.navigationController pushViewController: ickImageViewController animated:true]; 
    [ickImageViewController release]; 


2、利用UIViewController自身的presentModalViewController，进行跳转；调用dismissModalViewControllerAnimated方法可以返回。 
    PickImageViewController *ickImageViewController = [[PickImageViewController alloc] init]; 
    [self presentModalViewController:ickImageViewController animated:YES]; 
//返回 
[self dismissModalViewControllerAnimated:YES];
