ios - 如何像这样在 iOS7+ 中将自定义 UIView 添加到导航栏

Question

有没有办法像下图那样在 NavigationBar 中插入任何 UIView？

Answer 1

这行不通吗？

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame: CGRectMake(0.0f, 20.0f, 320.0f, 32.0f)];
UIView *tempView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];

[[self view] addSubview: tempView];
[[self view] addSubview: navBar];
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle: @"Controls"];
[navBar pushNavigationItem:navItem animated:NO];
