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。

当前回答

#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]];
    }

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];

- (void)viewDidLoad
{
    [super viewDidLoad];

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

在ios7中，你必须使用-barTintColor属性:

navController.navigationBar.barTintColor = [UIColor barColor];

//You could place this code into viewDidLoad
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    //change the nav bar colour
    self.navigationController.view.backgroundColor = [UIColor redColor];
    //change the background colour
    self.navigationController.navigationBar.translucent = NO;
 }   
//Or you can place it into viewDidAppear
- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:(BOOL)animated];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    //change the nav bar colour
    self.navigationController.view.backgroundColor = [UIColor redColor];
    //change the background colour
    self.navigationController.navigationBar.translucent = NO;
}

在viewcontroller或AppDelegate中只添加此代码

if([[[UIDevice currentDevice] systemVersion] floatValue] < 7.0)
{
    //This is For iOS6
    [self.navigationController.navigationBar setTintColor:[UIColor yellowColor]];
}
else
{
    //This is For iOS7
    [self.navigationController.navigationBar setBarTintColor:[UIColor yellowColor]];
}
