一、导航栏的背景和文字Color:
方法一:
- //设置NavigationBar 背景颜色&title 颜色
- [self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:20/255.0 green:155/255.0 blue:213/255.0 alpha:1.0]];
- [self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,nil]];
方法二:
- //设置NavigationBar背景颜色
- [[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];
- //@{}代表Dictionary
- [[UINavigationBar appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];
二、导航栏使用背景图片:
1. [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"nav_bg.png"] forBarMetrics:UIBarMetricsDefault];
三、导航栏标题的字体:
UITextAttributeFont - 字体
UITextAttributeTextColor - 文字颜色
UITextAttributeTextShadowColor - 文字阴影颜色
UITextAttributeTextShadowOffset - 偏移用于文本阴影
- 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 nil]];
四、图片作为导航栏标题:
- self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"appcoda-logo.png"]];
五、添加多个栏按钮项目:
- UIBarButtonItem *shareItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action: nil nil];
- UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action: nil nil];
- NSArray *itemsArr = @[shareItem,cameraItem];
- self.navigationItem.rightBarButtonItems = itemsArr;
六、自定义后退按钮的文字和颜色:
方法一:
- UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStylePlain target:nil action:nil];
- self.navigationItem.backBarButtonItem = item;
- [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
- [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor redColor],NSFontAttributeName:[UIFont systemFontOfSize:19.0]}];
- self.title=[NSString stringWithFormat:@"第%lu页",(unsigned long)self.navigationController.viewControllers.count];
- //自定义返回按钮
- UIImage *backButtonImage = [[UIImage imageNamed:@"fanhui.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 30, 0, 0)];
- [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
- //将返回按钮的文字position设置不在屏幕上显示
- [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(NSIntegerMin, NSIntegerMin) forBarMetrics:UIBarMetricsDefault];
