I have downloaded the source code of bridge from https://github.com/Microsoft/WinObjC/releases but with the help of vsimporter i can create a solution of ios project and then i can open that in visual studio, but can i open the bridge source code itself in visual studio for modifying and also in this blog https://blogs.windows.com/buildingapps/2015/08/06/windows-bridge-for-ios-lets-open-this-up/ there is mentioned like if the bridge hasn't support MPMoviePlayerController then we can create xaml mediaelement.
// WXCMediaElement is the Objective-C projection of
// Windows::UI::Xaml::MediaElement
WXCMediaElement *mediaElement = [WXCMediaElement create];
mediaElement.autoPlay = YES;
CALayer *mediaElementLayer = [CALayer layer];
[mediaElementLayer setFrame:CGRectMake(10, 10, 320, 240)];
[mediaElementLayer setContentsElement: mediaElement];
mediaElement.source = [WFUri createUri: @"ms-appx:///myvideo.mp4"];
// Now we just add the layer to be part of a UIView
[[containingView layer] addSublayer: mediaElementLayer];
So should i modify this in bridge source code or after importing do i have to add in windows phone project source code(visual studio).
