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。

//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;
}

其他回答

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]];
    }

在基于导航的应用程序中，您可以更改颜色

NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
if ([[ver objectAtIndex:0] intValue] >= 7) {
    self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];
    self.navigationController.navigationBar.translucent = NO;
} else {
    self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];
}

在ios7中，你必须使用-barTintColor属性:

navController.navigationBar.barTintColor = [UIColor barColor];

在viewDidLoad中，设置:

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

更改(blueColor)为任何你想要的颜色。
