Ios – How to get hash fragment of URL from UIWebView

fragmenthashiosnsurluiwebview

I'm trying to get hash fragment of URL loaded in UIWebView, I have tried different approaches it does not seem to work.

For example if the UIWebView is loaded with "http://www.mysite.com/home#main":

NSURL *url = [NSURL URLWithString:@"http://www.mysite.com/home#main"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];

then I want to get the full url, but it only return "http://www.mysite.com/home" with 3 different approaches:

NSString *currentURL = [webView.request.URL absoluteString];

NSString *currentURL = [NSString stringWithFormat:@"%@",[[webView request] URL]];

NSString *currentURL = [webView stringByEvaluatingJavaScriptFromString:@"window.location.hash"];

what am I missing

Try NSString *fragment = [webView.request.URL fragment];

Java – How to generate an MD5 hash in Java

The MessageDigest class can provide you with an instance of the MD5 digest.

When working with strings and the crypto classes be sure to always specify the encoding you want the byte representation in. If you just use string.getBytes() it will use the platform default. (Not all platforms use the same defaults)

import java.security.*;

..

byte[] bytesOfMessage = yourString.getBytes("UTF-8");

MessageDigest md = MessageDigest.getInstance("MD5");
byte[] theMD5digest = md.digest(bytesOfMessage);

If you have a lot of data take a look at the .update(xxx) methods which can be called repeatedly. Then call .digest() to obtain the resulting hash.

Objective-c – Display a webpage inside a UIWebView

If this is the exact code you're using then it can't work: the webView added to topView that is never put on screen anywhere.

You probably want to add the webView to the controller view, but a better place to do that might be viewDidLoad, where self.view can be used safely.

This code works for me:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.webView = [[[UIWebView alloc]
        initWithFrame:CGRectMake(0, 0, 320, 480)] autorelease];

    NSString *urlAddress = @"http://www.google.com";
    NSURL *url = [[[NSURL alloc] initWithString:urlAddress] autorelease];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    [self.webView loadRequest:requestObj];

    [self.view addSubview:self.webView];
}
