導航條的自定義需要繼承 UINavigationController

新建一個類：MyNav 繼承 UINavigationController

判斷系統版本

#define iOS7 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)

實現導航條自定義圖片：在viewDidload裏面添加

// 1.取出設置主題的對象
    UINavigationBar *navBar = [UINavigationBar appearance];
    
    // 2.設置導航欄的背景圖片
    NSString *navBarBg = nil;
    if (iOS7) { // iOS7
        navBarBg = @"navBG";
        navBar.tintColor = [UIColor whiteColor];        //IOS7版本纔有，設置導航條的左按鈕的顏色
    } else { // 非iOS7
        navBarBg = @"navBG";
        [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlackTranslucent;
    }
    [navBar setBackgroundImage:[UIImage imageNamed:navBarBg] forBarMetrics:UIBarMetricsDefault];
    
    // 3.設置標題顏色
    [navBar setTitleTextAttributes:@{ UITextAttributeTextColor : [UIColor whiteColor] }];

在頁面裏面

[self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"background"]]];
    [self setTitle:@"第二個頁面"];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"back"] style:UIBarButtonItemStyleDone target:self action:@selector(backBarButtonItem)];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Add" style:UIBarButtonItemStylePlain target:self action:@selector(perFormAdd:)];//爲導航欄添加右側按鈕  
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(perFormAdd:)];//爲導航欄左側添加系統自定義按鈕

self.title = @"頁面名字";
    self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleBordered target:nil action:nil];		//下一頁出來的導航條返回按鈕是  返回 兩個字

UISwitch *simpleSwitch = [[UISwitch alloc] init];//實例化一個選擇開關
    simpleSwitch.on = YES;//開關設置爲開啓狀態
    [simpleSwitch addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];//添加事件
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:simpleSwitch];//將開關控件賦給導航欄右按鈕

對開關添加事件

-(void)switchChanged:(UISwitch *)paramSender{
    if ([paramSender isOn]) {//如果開關狀態爲開啓
        NSLog(@"Switch is on.");
    }else{
        NSLog(@"Switch is off.");
    }
}
