从静态库访问 self.view
所以我正在为 iOS 制作一个静态库。基本上我希望人们能够调用这样的东西：
[MyStaticLibrary showview]
我的静态库将子视图添加到他们当前的视图中。通常我可能会这样做：
CGRect mainframe = [[UIScreen mainScreen] bounds];
UIView *mView = [[UIView alloc] initWithFrame:mainframe];
//Add some stuff to the view
[self.view addSubview:mView];
但是 xcode 正在抱怨，并且理所当然地，我无法从静态库访问 self.view，因为我当前在静态库中使用 NSObject。无论如何，我是否可以从静态库访问“self.view”，以便我可以将视图添加到应用程序屏幕？
So I'm making a static library for iOS. Basically I want people to be able to call something like this:
[MyStaticLibrary showview]
And my static library to add a subview to their current view. Normally I might do something like this:
CGRect mainframe = [[UIScreen mainScreen] bounds];
UIView *mView = [[UIView alloc] initWithFrame:mainframe];
//Add some stuff to the view
[self.view addSubview:mView];
But xcode is complaining, and rightfully so, that I can't access self.view from the static library since I'm currently using an NSObject in my static library. Is there anyway for me to access the "self.view" from my static library so I can add a view to the application screen?

1) 您可以将
showview方法调整为showViewInParentView:并允许调用者为您提供所需的视图。2) 您可以使用
[[[UIApplication sharedApplication] keyWindow] addSubview:mView]将库的视图直接添加到窗口，确保它位于顶部。我推荐 #1 而不是 #2。
1) You could adapt your
showviewmethod to beshowViewInParentView:and allow the caller to give you the view you need.2) You could use
[[[UIApplication sharedApplication] keyWindow] addSubview:mView]to add the library's view directly to the window, ensuring that it is on top.I recommend #1 over #2.
