在哪里更改 iPhone 应用程序导航栏的高度?
在我的 applicationDidFinishLaunching 中,我设置了一个 UINavigationController:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
navController = [[UINavigationController alloc] init];
[[navController navigationBar] setFrame:CGRectMake(0.0,0.0,320.0,20.0)];
...
}
如您所见,我试图将导航控制器的高度设置为 20px。然而,这是行不通的。我想 setFrame 一定是正确的函数,但我没有在正确的位置调用它。我意识到 SO 上的其他问题与我的类似,但我认为如果它响应 setFrame,设置 navigationBar 高度应该是可能的......对吗?
另外,有人知道导航栏的默认高度吗?
谢谢!
In my applicationDidFinishLaunching I set up a UINavigationController:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
navController = [[UINavigationController alloc] init];
[[navController navigationBar] setFrame:CGRectMake(0.0,0.0,320.0,20.0)];
...
}
As you can see, I am trying to make the navigation controller's height 20px. However, this is not working. I would imagine setFrame must be the correct function but I am not calling it in the right place. I realize that other questions on SO are similar to mine, but I think setting the navigationBar height should be possible if it responds to setFrame...right?
Also, anyone know the default height of the navigationBar?
Thanks!

导航栏的默认高度为 44px。
我不确定您是否应该尝试直接调整导航栏的大小,文档肯定不鼓励这样做:
根据您想要执行的操作,将新的 UIView 放置在导航栏上方/下方可能会更容易。
The default height of the navigation bar is 44px.
I am not sure you should be attempting to directly resize the navigation bar, the documentation certainly discourages it:
Depending on what you are trying to do it may be easier to place a new UIView over/below the navigation bar.
导航栏的默认高度为 44 像素。
如果您想更改它,请尝试向 UINavigationBar 添加一个类别并覆盖 setFrame: 方法。
Default height is 44 pixels for navigationbar.
If you want to change it, try adding a category to UINavigationBar and override setFrame: method.
