如何删除iOS 7的后退箭头导航栏? [英] How to remove the back arrow ios 7 navigation bar?

问题描述

在我的自定义导航栏中，我想使用隐藏默认后退"按钮并使用我的自定义左按钮，但是即使后退"按钮被隐藏，它也会在导航栏的左端占用一些空间.

In my custom navigation bar, i want to use hide default back button and use my customize left button, but even if the back button is hidden, it sill take some space at the left end of navigation bar.

如何完全摆脱后退箭头按钮?我试图设置 backBarButtonItem 和' NavNavigationItem`的'hidesBackButton 属性，但是这些都不起作用.

How to get rid of back arrow button completely? I have tried to set backBarButtonItem and 'hidesBackButtonproperties ofUINavigationItem`, but none of these works.

已更新:

- (void) viewDidLoad{
//...
self.navigationItem.hidesBackButton = YES;
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_backButtonView];
//...
}

我使用Spark Inspector检查视图层次结构.

I use Spark Inspector to inspect the view hierarchy.

如您所见，后退箭头按钮仍在导航栏中占据一些空间.

As you see, the back arrow button still takes some space in navigation bar.

已更新:

后退箭头实际上是_UINavigationBarBackIndicatorView的一个实例，它看起来像一个私有类.

The back arrow is actually an instance of _UINavigationBarBackIndicatorView, it look like a private class.

已更新:

事实证明，该问题与 UINavigationbarBackIndicatorView 无关.iOS 7将在左侧项目之前添加空格.

It turns out the problem have nothing to do with the UINavigationbarBackIndicatorView. iOS 7 will add spacing before the left item.
