推荐答案

你可以't 隐藏它。您可以添加掩盖它的子视图。示例：

You can't hide it. You can add a subview that will mask it. Example:

UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 43, 320, 1)];
[overlayView setBackgroundColor:[UIColor whiteColor]];
[navBar addSubview:overlayView]; // navBar is your UINavigationBar instance
[overlayView release];

我没有检查，但它应该有用。

I didn't check it, but it should work.

编辑：我查了一下，确实有效。

I checked it, it works.
