   1: solution to URLWithString initialization failure

   1. NSString* StrLocalHtml=@ File: // Users/amarishuyi/Desktop/MyIPhoneLife/WebDeveloper/WebPlug-in/ExtEditor/DataPage/KMQT/Ext-HTMLEditor.html;
   2. StrLocalHtml=[NSStringStringWithFormat: @ % @? Value00000000@,strlocalhtml,self.txt Url. text];
   3. StrLocalHtml =[StrLocalHtmlStringByAddingPercentEscApesUsingEncoding: NSUTF8StringEncoding];
   4. NSURL*Url = [NSURLURLWithString: strLocalHtml];

      2: Solution for fileURLWithPath initialization failure

      1. Self. filePathString=[Self. filePathStringStringByReplacingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
      2. NSURL* Url=[NSURLFileURLWithPath: self. filePathString];
         After transcoding is successful, it is automatically added to the left side of the string.File :///

         
          

          

          

         3: parameters that can be obtained after successful NSURL initialization (from: NSURL Learning)

          

         1. NSURL* Url=[NSURLURLWithString: @ Www.bkjia.com? Tn = baiduhome_pg & bs = nsul & f = 8 & rsv_bp = 1 & rsv_spt = 1 & wd = NSurl & inputT = 2709];
         2. NSLog (@ Scheme:% @,[UrlScheme]);
         3. NSLog (@ Host:% @,[UrlHost]);
         4. NSLog (@ Port:% @,[UrlPort]);
         5. NSLog (@ Path:% @,[UrlPath]);
         6. NSLog (@ RelativePath:% @,[UrlRelativePath]);
         7. NSLog (@ PathComponentsAsArray:% @,[UrlPathComponents]);
         8. NSLog (@ ParameterString:% @,[UrlParameterString]);
         9. NSLog (@ Query:% @,[UrlQuery]);
         10. NSLog (@ Fragment:% @,[UrlFragment]);
         11. NSLog (@ User:% @,[UrlUser]);
         12. NSLog (@ Password:% @,[UrlPassword]);

             The result is as follows:
