iOS11自定义导航栏高度

问题描述

首先，感谢您来到这里并帮助解决我的问题。谢谢!!!

First of all, thank you for coming here and help solving my problem. Thank you!!!

在iOS11 beta6中， sizeThatFits：似乎无法在UINavigationBar上运行。我注意到通过显示我的应用程序改变了UINavigationBar结构。

In iOS11 beta6, sizeThatFits: seems to not work on UINavigationBar. I notice that UINavigationBar structure has changed by Reveal my app.

我已经尽力改变自定义导航栏的高度。但似乎总是 44 ，它在iOS11之前有效。

I have tried my best to change custom navigation bar's height. But it seems always to be 44, and it works before iOS11.

- (CGSize)sizeThatFits:(CGSize)size {
    CGSize newSize = CGSizeMake(self.frame.size.width, 64);
    return newSize;
}

奇怪的是，我只是在中记录了它的框架didMoveToSuperview 方法，它的高度是64，但我真的看到在Reveal和app中是44。

Oddly, I just log its frame in didMoveToSuperview method, its height is 64, but I really see that is 44 in Reveal and app.

我对此一无所知...请帮帮我..谢谢你。

I have no idea about this... Help me please.. Thank you.

我发现关于我的自定义导航栏LayoutConstraints登录控制台如下：

I found that about my custom navigation bar LayoutConstraints log in console like this :

"<NSAutoresizingMaskLayoutConstraint:0x604000495ae0 FDCustomNavigationBar:0x7fe2f01399d0.(null) == 42>",
"<NSAutoresizingMaskLayoutConstraint:0x604000495b30 FDCustomNavigationBar:0x7fe2f01399d0.height == 44>"`

bug我甚至没有使用自动布局我的导航栏。这有什么问题？

bug I even no use auto layout in my navigation bar. What's wrong with it?

我在导航栏的<$ c设置了我的自定义导航栏的子视图框架$ c> -
layoutSubviews 方法。

- (void)layoutSubviews {
    [super layoutSubviews];

    self.frame = CGRectMake(0, 0, CGRectGetWidth(self.frame), 64);

    for (UIView *view in self.subviews) {

        if([NSStringFromClass([view class]) containsString:@"Background"]) {
            view.frame = self.bounds;
        } else if ([NSStringFromClass([view class]) containsString:@"ContentView"]) {
            CGRect frame = view.frame;
            frame.origin.y = 20;
            frame.size.height = self.bounds.size.height - frame.origin.y;
            view.frame = frame;
        }
    }
}

但导航栏将覆盖查看控制器的视图。我该如何解决这个问题？

but the navigation bar will cover view controller's view. How can I fix that?

推荐答案

由于iOS 11 UINavigationBar完全支持自动布局（这就是你看到它的原因约束）。我已经向Apple打开了雷达，因为我认为为titleView设置高度约束会相应地调整导航栏高度。然而，这就是Apple回复的内容：

Since iOS 11 UINavigationBar fully supports Auto Layout (this is the reason why you're seeing its constraints). I've opened a radar to Apple because I thought that setting a height constraint to the titleView would have adjusted the navigation bar height accordingly. However this is what Apple replied:

截至今天，雷达仍处于打开状态。

As of today the radar is still open.
