javascript - UIWebView retrieve a link and navigate to it -

-

I'm adding a UIWebView to my app, which should load the password-protected webpage. Automatically select a link from that page and navigate to that page. This website constantly changes, so there is no way to choose the intended page URL. I must first login and then select a link from the main page

After logging in for the desired link, how can I code and navigate to search my main page Am I

I think that will help. NSError * Error will handle NSError errors; 

  // Create the URL for your page Http://example.com/index.php Just one example NSURL * pageURL = [NSURL URLWithString: @ "http://example.com/index.php"]; // Recover page regex to parse it by using NSString * pageHtml = [NSString stringWithContentsOfURL: PAGEURL encoding: NSUTF8StringEncoding error: & amp; Error]; If (error) {NSLog (@ "Error retrieving HTML:% @", error); // will terminate my app (); // TODO: handle the connection error here} error = zero; // Creating regex to parse // page html // You can easily find it. NSRegularExpression * regex = [[NSRegularExpression alloc] initWithPattern: @ "& lt; a [^ & gt;] * href = \" [[^ \ "] *) \" [^ & gt;] * & gt; MyLink & lt; / A & gt; "Option: NSRegularExpressionCaseInsensitive error: & amp; error; if (error) {NSLog (@" error while creating regex:% @ ", error); // will terminate your app;) TODO: handle regex error here } // Getting our first match of regex is to get the first group NSTextCheckingResult * match = [regex firstMatchInString: pageHtml option: 0 range: NSMakeRange (0, [pageHtml length])]; NSString * PAGEURL = [pageHtml substringWithRange: [Match rangeAtIndex: 1]]; NSLog (@ "Page URL =% @" PAGEURL), [WebView loadRequest: [NSURLRequest requestWithURL: [NSURL URLWithString: PAGEURL]]];   
 With your  UIWebView  HTML From the Halle download page you can replace  
  NSURL * PAGEURL = [NSURL URLWithString: @ "http://example.com/index.php"]; NSString * pageHtml = [NSString StringWithContentsOfURL: Page URL Encoding: NSUTF8StringEncoding Error: & amp; Error];   
 With this:  
  NSString * pageHtml = [Webview stringBuViewting JavaScriptFrameString: @ "Document.body.innerHTML"];

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
