我如何改变导航栏的颜色在iOS 7?

基本上我想要实现类似Twitter导航栏的东西(更新的Twitter为iOS7)。我在视图控制器的顶部嵌入了一个导航条。所有我想要的是改变导航栏的颜色为浅蓝色连同顶部的工具栏。我似乎在我的故事板中找不到一个选项。

在一个基于导航的应用程序中，你可以把代码放在AppDelegate中。更详细的代码可以是:

// Navigation bar appearance (background and title)

[[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor titleColor], NSForegroundColorAttributeName, [UIFont fontWithName:@"FontNAme" size:titleSize], NSFontAttributeName, nil]];

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

// Navigation bar buttons appearance

[[UIBarButtonItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor textBarColor], NSForegroundColorAttributeName, shadowColor, NSShadowAttributeName, [UIFont fontWithName:@"FontName" size:titleSize], NSFontAttributeName, nil];

如果你需要支持ios6和ios7那么你在你的UIViewController中使用这个得到那个特别的浅蓝色:

- (void)viewDidLoad {
    [super viewDidLoad];
    NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
    if ([[ver objectAtIndex:0] intValue] >= 7) {
        self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:89/255.0f green:174/255.0f blue:235/255.0f alpha:1.0f];
        self.navigationController.navigationBar.translucent = NO;
    }else{
        self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:89/255.0f green:174/255.0f blue:235/255.0f alpha:1.0f];
    }
}

在ios7中，你必须使用-barTintColor属性:

navController.navigationBar.barTintColor = [UIColor barColor];

self.navigationBar.barTintColor = [UIColor blueColor];
self.navigationBar.tintColor = [UIColor whiteColor];
self.navigationBar.translucent = NO;

// *barTintColor* sets the background color
// *tintColor* sets the button's color

#define _kisiOS7 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)


  if (_kisiOS7)
    {
        [[UINavigationBar appearance] setBarTintColor:[UIcolor redcolor]];
    }
    else
    {
        [[UINavigationBar appearance] setBackgroundColor:[UIcolor blackcolor]];
        [[UINavigationBar appearance] setTintColor:[UIcolor graycolor]];
    }

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
}
