android 导航条色彩适应 导航栏配色方案

一、导航栏的背景和文字Color:

方法一：

1. //设置NavigationBar 背景颜色&title 颜色  
2. [self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:20/255.0 green:155/255.0 blue:213/255.0 alpha:1.0]];  
3. [self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,nil]];

方法二：

1. //设置NavigationBar背景颜色  
2. [[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];  
3. //@{}代表Dictionary  
4. [[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
1. NSShadow *shadow = [[NSShadow alloc] init];  
2. shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];  
3. shadow.shadowOffset = CGSizeMake(0, 1);  
4. [[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,  
5. shadow, NSShadowAttributeName,  
6. [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:21.0], NSFontAttributeName, nil nil]];

四、图片作为导航栏标题：

1. self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"appcoda-logo.png"]];

五、添加多个栏按钮项目：

1. UIBarButtonItem *shareItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action: nil nil];  
2. UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action: nil nil];  
3. NSArray *itemsArr = @[shareItem,cameraItem];  
4. self.navigationItem.rightBarButtonItems = itemsArr;

六、自定义后退按钮的文字和颜色：

方法一：

1. UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStylePlain target:nil action:nil];  
2. self.navigationItem.backBarButtonItem = item;  
3. [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];  
4. [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor redColor],NSFontAttributeName:[UIFont systemFontOfSize:19.0]}];  
5.   
6. self.title=[NSString stringWithFormat:@"第%lu页",(unsigned long)self.navigationController.viewControllers.count];  
7.   
8. //自定义返回按钮  
9. UIImage *backButtonImage = [[UIImage imageNamed:@"fanhui.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 30, 0, 0)];  
10. [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];  
11. //将返回按钮的文字position设置不在屏幕上显示  
12. [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(NSIntegerMin, NSIntegerMin) forBarMetrics:UIBarMetricsDefault];
