将SDL的视图embeddedUIViewController
我在iOS上看到的一些SDL演示，所有渲染发生在SDL_Window而不是UIWindow 。 但是，由于大多数iOS应用程序是基于单个UIWindowbuild模的。 我想将iOS与SDL集成，并将SDL的窗口（或SDL的视图）embedded到UIViewController视图中。 这是如何完成的？
我已经在这里发布我的问题，也看到下面的评论 michelleC说明以下，但我不知道如何编码michelleC提到的。 我无权在论坛上发帖/回复。
我很容易掌握sdl窗口，并添加视图控制器，或获得封装sdl视图，并将其添加到视图控制器。
到目前为止，我所做的是修改SDL_uikitviewcontroller.m以重新定位/调整SDL_Window视图的大小：
- (void)viewDidLayoutSubviews { CGRect newFrame = self.view.frame; newFrame.size.height = newFrame.size.height - 100; newFrame.size.width = newFrame.size.width - 50; newFrame.origin.x = 25.0f; self.view.frame = newFrame; SDLUIKitDelegate *appDelegate = [SDLUIKitDelegate sharedAppDelegate]; [appDelegate embedView:self.view]; }
然后我把这个视图传递给SDL_uikitappdelegate.m中的一个函数，在这里它将SDL_Window的视图作为UIViewController的子视图。 但是，我遇到的错误。

这个问题是由于我的代码引用了坏的variables。 embedView中的以下行应replace：
[self.window.rootViewController.view addSubview：vw];
同
[myWindow.rootViewController.view addSubview：vw];
