SDL2 - iOS subview orientation problem

SDL Development
1

Hello everyone!

I’m working on a project that use HTML5 to draw the user interface. So for iOS, I need to add a UIWebView to SDL’s UIWindow. I do that simply like this:

Code:

SDLwindow* sdlWindow = getWindow();
SDL_SysWMinfo info;
window* window;

SDL_VERSION(&info.version);

if (SDL_GetWindowWMInfo(sdlWindow, &info))
{
window = (info.info.uikit.window);

// Create the web view
UIWebView* webView = [[IOSWebView alloc] initWithFrame:window.bounds];
[webView setBackgroundColor: [UIColor clearColor]];
[webView setOpaque:NO];
webView.scrollView.scrollEnabled = NO;
webView.scrollView.bounces = NO;

// Add the web view to the current window
[window addSubview:webView];

// Load the user interface
NSURL *url = [NSURL fileURLWithPath:@"interface.html"];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];

}

That’s work great, I can see my interface over my SDL window but when I change the orientation of my device, only the SDL window rotate, the interface keep the same orientation all time.

I did a lot of researches and I found some solutions but they don’t work for me. Things I’ve tried was to change the webview’s autoresizingMask property like that:

Code:

webView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

But it doesn’t seem to work, the second to set the window’s autoresizesSubviews property to true:

Code:
window.autoresizesSubviews = YES;

Doesn’t work neither… And the last thing that I’ve tried was in Javascript:

Code:
[webView stringByEvaluatingJavaScriptFromString:@“var e = document.createEvent(‘Events’); e.initEvent(‘orientationchange’, true, false); document.dispatchEvent(e);”];

I’ve also seen a lot of messages that said to override shouldAutorotateToInterfaceOrientation method of the WebViewController, but I don’t have any controller for my webview. I tried to do something like that:

Code:

IOSWebViewController *iOSWebViewDelegate = [[IOSWebViewController alloc] init];
[webView setDelegate: iOSWebViewDelegate]; // Doesn’t work
webView.delegate = iOSWebViewDelegate; // Doesn’t work neither

But without any success… :’(

I’m not good at all with Objective-C, anybody to help me ?

Thanks in advance.

I think there is a law that says that even if we are stuck on a problem since several days, if we take the time to ask for help, we find the solution a couple of minutes later…

The solution for this problem was to add the WebView to the window.rootViewController.view instead of window directly.

Sorry for the inconvenience and have a nice day :wink:
