如何在 iOS 7 中更改导航栏颜色?

How do I change the Navigation Bar color in iOS 7?

基本上我想实现类似 Twitter Nav Bar 的东西(更新 Twitter for iOS7 就是这样).我在 view controller 顶部嵌入了一个导航栏.我想要的只是将导航栏颜色与顶部的实用程序栏一起更改为浅蓝色.我似乎在 storyboard 中找不到选项.

Basically I want to achieve something like the Twitter Nav Bar (updated Twitter for iOS7 that is). I embedded-in a nav bar atop a view controller. All I want is to change the nav bar color to light blue along with the utility bar at the top. I can't seem to find an option in my storyboard.

推荐答案

tintColor 对条形的行为在 iOS 7.0 中发生了变化.它不再影响栏的背景.

The behavior of tintColor for bars has changed in iOS 7.0. It no longer affects the bar's background.

来自文档:

barTintColor 类参考

应用于导航栏背景的色调.

The tint color to apply to the navigation bar background.

@property(nonatomic, retain) UIColor *barTintColor

讨论
除非您将 translucent 属性设置为 NO，否则此颜色默认为半透明.

Discussion
This color is made translucent by default unless you set the translucent property to NO.

可用性

适用于 iOS 7.0 及更高版本.

Available in iOS 7.0 and later.

声明于
UINavigationBar.h

NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
if ([[ver objectAtIndex:0] intValue] >= 7) {
    // iOS 7.0 or later   
    self.navigationController.navigationBar.barTintColor = [UIColor redColor];
    self.navigationController.navigationBar.translucent = NO;
}else {
    // iOS 6.1 or earlier
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
}

我们也可以使用它来检查 iOS 版本，如 iOS 7 UI 过渡指南

We can also use this to check iOS Version as mention in iOS 7 UI Transition Guide

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
        // iOS 6.1 or earlier
        self.navigationController.navigationBar.tintColor = [UIColor redColor];
    } else {
        // iOS 7.0 or later     
        self.navigationController.navigationBar.barTintColor = [UIColor redColor];
        self.navigationController.navigationBar.translucent = NO;
    }
