I have an NSData containing a .webarchive blob that I'd like to load into a UIWebView. I know that this is possible (see this question), and I have it working if I first serialize it to disk and then load it with UIWebView's -loadRequest: method.
However, I'd prefer not to serialize to disk first since I already have the data in memory. I've tried to use -loadData:MIMEType:textEncodingName:baseURL: with the data, and various base URLs, but it always fails (nil, @"http://", the actual root path that the web archive contains, etc) to load.
Again, the same archive loads correctly if I bounce it to disk first and load via -loadRequest:, so I feel like something about the MIMEType (I'm using application/octet-stream) and/or the base URL is wrong. Anyone know what the incantation is?
Using -loadData:... will work. The MIME type specified must be application/x-webarchive (not the generic "octet-stream"). If this is set correctly, both the text encoding and base URL can be just supplied as nil.
