UINavigationController导航控制器

-------------------------------------------------------------------------

//(初始化)导航栏竖屏44,还有20的标题,横屏32

//iPhone : 竖屏 44 横屏 32,iPad: 44

     UINavigationController * navVC = [[UINavigationController alloc] initWithRootViewController:firstVC];

---

//导航栏透明度(默认半透明)
navVC.navigationBar.translucent = NO;

---

//返回键的颜色
    navVC.navigationBar.tintColor = [UIColor whiteColor];

---

//导航栏背景色
    navVC.navigationBar.barTintColor = [UIColor greenColor];

---

//是否隐藏导航栏
navVC.navigationBarHidden = NO;

---

//导航栏设置背景图
//如果图片的尺寸是320*44,则图片显示在导航栏上
//如果图片尺寸是320* 64,则图片从状态栏开始显示
//如果两个都不是,则从状态栏开始平铺图片
    [navVC.navigationBar setBackgroundImage:[UIImage imageNamed:@"title_bg.png"] forBarMetrics:UIBarMetricsDefault];

---

---

---

---

//设置背景色,不设可能产生BUG;
    self.view.backgroundColor = [UIColor redColor];

---

//设置标题
    self.navigationItem.title = @"首页";

---

//在导航栏添加按钮
    self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemBookmarks target:self action:@selector(bar)] autorelease];

//法二

self.navigationItem.rightBarButtonItem = self.editButtonItem;

- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];
    [self.tabBarController setEditing:editing animated:YES];

}

---

//是否隐藏返回按钮
    self.navigationItem.hidesBackButton = YES;

---

//推向下一页

[self.navigationController pushViewController:deta animated:YES];

---

//几种翻页时效果(魔态)[枚举]

deta.modalTransitionStyle = UIModalPresentationPageSheet;

//点按钮弹出一个视图或视图控制器(魔态)
    [self presentViewController:detaVC(下一页面) animated:YES completion:^{NSLog(@"finishi ");}];

//到下一页返回(取消弹出)

- (void)dismissPage
{
    [self dismissViewControllerAnimated:YES completion:^{}];
}

---

//返回到首页
    [self.navigationController popToRootViewControllerAnimated:YES];

//返回到上一层
    [self.navigationController popViewControllerAnimated:YES];

//返回到指定界面
    [self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:1] animated:YES];

---

//再所有页面中找到tabView,reloadData刷新页面
        NSArray *allControllers = self.navigationController.viewControllers;

//找到指定页面
        UITableViewController *tableViewController = [allControllers objectAtIndex:[allControllers count]-2];
        [tableViewController.tableView reloadData];//刷新页面

修改navigationBar title的背景颜色 

 

这个方法在iOS5以后可以这样用

navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor yellowColor] forKey:UITextAttributeTextColor];

 

通过以下key值修改起属性

UITextAttributeFont

UITextAttributeTextShadowOffset

UITextAttributeTextShadowColor
