在UINavigationController中设置自定义导航栏类

Question

我有一个自定义navigationBar:

class Name_UINavigationBar: UINavigationBar {
    // code
}

我想以编程方式将其设置为我的导航控制器.所以我尝试过:

var navController : UINavigationController = UINavigationController(
            navigationBarClass: object_getClass(Name_UINavigationBar),
            toolbarClass: nil)
// code

但它崩溃说:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', 
    reason: 'MyProject.Name_UINavigationBar is not a subclass of UINavigationBar'

Answer 1

试试这个.

let navController = UINavigationController(navigationBarClass: YourNavigationBar.self, toolbarClass: nil)

我遇到了同样的错误,并且能够让它再次运行.
