How to convert NSData with textEncoding utf-8 into NSURL

I want to convert NSData (textEncoding utf-8) into NSURL. I am writing below code for this, but conversion from NSData to NSString returning nil. (May be due to encoding type)

NSString *stringFromData = [[NSString alloc] initWithData:myData encoding:NSUTF8StringEncoding]; // stringFromData is nil after execution of this line.
NSURL *url = [[NSURL alloc] initWithString:stringFromData];

So what should I do to convert NSData into NSURL in my case.

But when I am trying to load this data into webview, Its working good. Here is my code to load this data into webview.

[self.webView loadData:myData MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil]; //PDF is showing in my webview.

but I am not able to convert this NSData into NSURL. What encoding should I use to convert NSData with textEncoding utf-8 into NSURL ?

Solution

  • You're trying to load data that represents a PDF into an NSString. A PDF file does not consist of UTF-8 encoded characters that represent text, it's a file that contains header information, fonts, vector graphics AND text.

    The only solution to your problem in my mind is change the source of the NSData to something that will provide UTF-8 encoded characters that make up a URL.

    If you can't get data any other way, why not check if you can extract the textual data from the PDF? https://github.com/zachron/pdfiphone
