ios 导航栏不能使用dismissviewcontrolleranimated方法吗
本文是使用纯代码实现一个导航栏的效果。单击按钮并且产生事件。基本思路是：
1.创建一个导航栏（UINavigationBar对象）
2.创建一个导航栏集合（UINavigationItem对象）
3.创建一个左边按钮、一个右边按钮（UIBarButtonItem对象），并实现对应的事件方法
4.将导航栏集合添加到导航栏中，设置动画关闭
5.把左右两个按钮添加到导航栏集合中去
6.在视图中显示当前创建的导航栏
可以用animated
具体的实现代码如下：
ViewController.h文件中的代码不用改变，如下所示：
[cpp] view
plaincopyprint?
#import UIKit/UIKit.h
@interface ViewController : UIViewController
@end
#import UIKit/UIKit.h
@interface ViewController : UIViewController
@end
ViewController.m文件中的代码：
[cpp] view
plaincopyprint?
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//创建一个导航栏
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
//创建一个导航栏集合
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:nil];
//在这个集合Item中添加标题，按钮
//style:设置按钮的风格，一共有三种选择
//action：@selector:设置按钮的点击事件
//创建一个左边按钮
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:@"左边" style:UIBarButtonItemStyleBordered target:self action:@selector(clickLeftButton)];
//创建一个右边按钮
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"右边" style:UIBarButtonItemStyleDone target:self action:@selector(clickRightButton)];
//设置导航栏的内容
[navItem setTitle:@"凌凌漆"];
//把导航栏集合添加到导航栏中，设置动画关闭
[navBar pushNavigationItem:navItem animated:NO];
//把左右两个按钮添加到导航栏集合中去
[navItem setLeftBarButtonItem:leftButton];
[navItem setRightBarButtonItem:rightButton];
//将标题栏中的内容全部添加到主视图当中
[self.view addSubview:navBar];
//最后将控件在内存中释放掉，以避免内存泄露
[navItem release];
[leftButton release];
[rightButton release];
}
-(void)showDialog:(NSString *)str
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"这是一个对话框" message:str delegate:self cancelButtonTitle:@"确定" otherButtonTitles: nil];
[alert show];
[alert release];
}
-(void) clickLeftButton
{
[self showDialog:@"点击了导航栏左边按钮"];
}
-(void) clickRightButton
{
[self showDialog:@"点击了导航栏右边按钮"];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

ios 怎么自定义导航栏的过度动画
在导航控制器中，通过push到另外一个控制器，这个控制器会左上角会自带“Back” ，点击会回退到上个控制器。如果想要自定义返回键，也可以通过将button添加到导航栏上的leftBarButtonItem 来模拟。
