how to make NSURL point to local dir?

StackOverflow https://stackoverflow.com/questions/14096893

Question

reading Adium code today, found an interesting usage of NSURL:

NSURL *baseURL = [NSURL URLWithString:[NSString stringWithFormat:@"adium://%@/adium", [messageStyle.bundle bundleIdentifier]]];
[[webView mainFrame] loadHTMLString:[messageStyle baseTemplateForChat:chat] baseURL:baseURL];

I tried to log the url and got this adium://im.adium.Smooth Operator.style/adium, Then I created a blank project to see how to create such an NSURL but failed. When I sending loadHTMLString message to a webview's frame in my project, if the baseURL is nil, everything is fine, if not, I got a blank page in the view.

here is my code, the project name is webkit

NSURL *baseURL = [NSURL URLWithString:@"webkit://resource"];
//if baseURL is nil or [[NSBundle mainBundle] bundleURL], everything is fine
[[webView mainFrame] loadHTMLString:@"<html><head></head><body><div>helloworld</div></body></html>" 
                     baseURL: baseURL];
[frameView setDocumentView:webView];
[[frameView documentView] setFrame:[frameView visibleRect]];

the question is how to make a self defined protocol instead of http://?

Was it helpful?

Solution

adium://%@/adium , first section is called protocol you can also register your protocol webkit: Take a look at How to map a custom protocol to an application on the Mac? and Launch Scripts from Webpage Links

OTHER TIPS

[NSURLProtocol registerClass:[AIAdiumURLProtocol class]];
[ESWebView registerURLSchemeAsLocal:@"adium"];

I tried to find where did adium define the adium schema in the info.plist, unfortunately, there's nothing there, only some irc/xmpp protocols.

so I finally launched the debugger, and found the code above in the AIWebKitDelegate init method, anyway this is another way to register a self defined protocol~
