  • UINavigationBar导航栏相关设置

    设置导航颜色

    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1]];

    [[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];

    设置导航文字颜色

    [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

    设置导航背景

    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"nav_bg.png"] forBarMetrics:UIBarMetricsDefault];

     

    设置多个导航按钮

    UIBarButtonItem *shareItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:nil]; 

    UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:nil]; 

    NSArray *actionButtonItems = @[shareItem, cameraItem];

     self.navigationItem.rightBarButtonItems = actionButtonItems;

    设置导航字体

    NSShadow *shadow = [[NSShadow alloc] init]; 

    shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8]; 

    shadow.shadowOffset = CGSizeMake(0, 1); 

    [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys: [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName, shadow, NSShadowAttributeName, [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:21.0], NSFontAttributeName, nil]];

     

     

    说法二:

    方法1

    导航向上添加一个titleView,可以使用一个label,再设置label的背景颜色透明,字体什么的设置就很简单了。 

    //自定义标题视图

    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];

    titleLabel.backgroundColor = [UIColor grayColor];

    titleLabel.font = [UIFont boldSystemFontOfSize:20];

    titleLabel.textColor = [UIColor greenColor];

    titleLabel.textAlignment = NSTextAlignmentCenter;

    titleLabel.text = @"新闻";

    self.navigationItem.titleView = titleLabel;

    方法2

    //    设置 标题的颜色和字号

        [self.navigationBar setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:2

    0],NSForegroundColorAttributeName:[UIColor whiteColor]}];

        self.navigationBar.barTintColor =[UIColor whiteColor]];

    设置tabbar的背景颜色

    self.tabBar.barTintColor = [UIColor whiteColor];
