使导航栏在xCode 5 / iOS7中的状态栏后面伸展 [英] Make Navigation Bar stretch behind status bar in xCode 5 / iOS7

问题描述

我已按照以下教程将我的导航栏向下移动，因此xcode 5 / ios7中的状态栏不会覆盖它：

I have followed the following tutorial to move my navigation bar down so it is not covered by the status bar in xcode 5/ios7:

IOS7中的状态栏和导航栏问题

但现在在iOS7中，状态栏顶部会有一个空白区域，我希望导航栏也能填满这个区域

But now in iOS7 there is a blank space at the top where the status bar would be and I would like the navigation bar to fill this area too

例如，Facebook / twittter / Instagram iOS7应用程序的状态栏后面也有导航栏背景。我如何实现这一目标？

For instance, Facebook/twittter/Instagram iOS7 apps have the navigation bar background behind the status bar too. How do I achieve this?

对不起，如果我不清楚但真的渴望得到这个分类

Sorry if I'm not being clear but really eager to get this sorted

谢谢！

推荐答案

你想设置 barPosition UINavigationBar 。

您可以在代码中执行此操作：

让ViewController符合协议 UINavigationBarDelegate 并实现positionBar：metod。 （你真正需要的协议是 UIBarPositioningDelegate 但是 UINavigationBarDelegate 确实扩展了它。）

Let your ViewController conform to protocol UINavigationBarDelegate and implement positionBar: metod. (The protocol that you really need is UIBarPositioningDelegate but UINavigationBarDelegate does extend it.)

@interface SampleViewController () <UINavigationBarDelegate>
@property (weak, nonatomic) IBOutlet UINavigationBar *navigationBar;
@end

@implementation SampleViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    _navigationBar.delegate = self;
}

- (UIBarPosition)positionForBar:(id<UIBarPositioning>)bar {
    return UIBarPositionTopAttached;
}
@end

或在故事板中

在 UINavigationBar 的I​​dentity Inspector中，添加一个用户定义的运行时属性，KeyPath = barPosition，Type = Number ，和Value = 3：

In the Identity Inspector of UINavigationBar, add a User Defined runtime Attribute with KeyPath = barPosition, Type = Number, and Value = 3:
