IOS系列——自定义导航条

来源：互联网发布：wall control软件下载编辑：程序博客网时间：2024/06/03 11:17

导航条的自定义需要继承 UINavigationController

新建一个类：MyNav 继承 UINavigationController

判断系统版本

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

实现导航条自定义图片：在viewDidload里面添加

// 1.取出设置主题的对象    UINavigationBar *navBar = [UINavigationBar appearance];        // 2.设置导航栏的背景图片    NSString *navBarBg = nil;    if (iOS7) { // iOS7        navBarBg = @"navBG";        navBar.tintColor = [UIColor whiteColor];        //IOS7版本才有，设置导航条的左按钮的颜色    } else { // 非iOS7        navBarBg = @"navBG";        [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlackTranslucent;    }    [navBar setBackgroundImage:[UIImage imageNamed:navBarBg] forBarMetrics:UIBarMetricsDefault];        // 3.设置标题颜色    [navBar setTitleTextAttributes:@{ UITextAttributeTextColor : [UIColor whiteColor] }];

在页面里面

[self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"background"]]];    [self setTitle:@"第二个页面"];    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:)];//为导航栏添加右侧按钮      self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(perFormAdd:)];//为导航栏左侧添加系统自定义按钮

self.title = @"页面名字";    self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleBordered target:nil action:nil];//下一页出来的导航条返回按钮是  返回 两个字

UISwitch *simpleSwitch = [[UISwitch alloc] init];//实例化一个选择开关    simpleSwitch.on = YES;//开关设置为开启状态    [simpleSwitch addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];//添加事件    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:simpleSwitch];//将开关控件赋给导航栏右按钮

对开关添加事件

-(void)switchChanged:(UISwitch *)paramSender{    if ([paramSender isOn]) {//如果开关状态为开启        NSLog(@"Switch is on.");    }else{        NSLog(@"Switch is off.");    }}
