How to Call Https Url in Uiwebview

How to call https url in uiwebview (swift)?

i find a way to do this,but i think this is not a good way.

step 1------use NSURLConnection in override func viewDidLoad(){} section
request = NSURLRequest(URL:url)

    let urlConnection:NSURLConnection = NSURLConnection(request: request, delegate: self)!

step 2------ use the NSURLConnection delegate to

func connection(connection: NSURLConnection, didFailWithError error: NSError){
    println("didFailWithError")
}

func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace) -> Bool{
    println("canAuthenticateAgainstProtectionSpace")
    //return [protectionSpace.authenticationMethodisEqualToString:NSURLAuthenticationMethodServerTrust];
    return true
}

func connection(connection: NSURLConnection, didReceiveAuthenticationChallenge challenge: NSURLAuthenticationChallenge){
    println("did autherntcationchallenge = \(challenge.protectionSpace.authenticationMethod)")

    //if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust && challenge.protectionSpace.host == "myDomain.com" {

    if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust  {
        println("send credential Server Trust")
        let credential = NSURLCredential(forTrust: challenge.protectionSpace.serverTrust)
        challenge.sender.useCredential(credential, forAuthenticationChallenge: challenge)

    }else if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodHTTPBasic{
        println("send credential HTTP Basic")
        var defaultCredentials: NSURLCredential = NSURLCredential(user: "username", password: "password", persistence:NSURLCredentialPersistence.ForSession)
        challenge.sender.useCredential(defaultCredentials, forAuthenticationChallenge: challenge)

    }else if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodNTLM{
        println("send credential NTLM")
        if challenge.previousFailureCount > 0 {
            //如果连续两次验证未通过，则终止， 还需要返回自定义出错界面
            //handle bad credentials scenario
        }

        var defaultCredentials: NSURLCredential = NSURLCredential(user: "username", password: "password", persistence:NSURLCredentialPersistence.ForSession)
        challenge.sender.useCredential(defaultCredentials, forAuthenticationChallenge: challenge)
        }

    } else{
        challenge.sender.performDefaultHandlingForAuthenticationChallenge!(challenge)
    }
    //challenge.sender.performDefaultHandlingForAuthenticationChallenge!(challenge)
    //challenge.sender.continueWithoutCredentialForAuthenticationChallenge(challenge)
}

/*
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {

}*/
func connection(connection: NSURLConnection, didCancelAuthenticationChallenge challenge: NSURLAuthenticationChallenge){
    println("didCancelAuthenticationChallenge")
}
/*
- (void)connection: (NSURLConnection *)connection willSendRequestForAuthenticationChallenge: (NSURLAuthenticationChallenge *)challenge
{
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}*/

func connection(connection: NSURLConnection, didReceiveResponse response: NSURLResponse){
    println("-----received response");

    // remake a webview call now that authentication has passed ok.

    //_authenticated =YES;

    //[_webloadRequest:_request];
   webView.loadRequest(request)

    // Cancel the URL connection otherwise we double up (webview + url connection, same url = no good!)

    //[_urlConnectioncancel];
}

it can work

sorry for my poor english skill

How to call https url in uiwebview?

I have explained below how to access https url in UIWebview it will help you clear the problem because it works for me.

Calling http is same as https url.

If, however, you're using a self-signed certificate, it's necessary to add some additional code.Because by default iOS will reject all untrusted https connections.

Restricting untrusted connections is very good default behaviour and any disabling of this is highly risky.So we will show an alert as we're going to bypass the default behaviour.

-(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace;

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;

These two above methods allows us to provide our own authentication mechanism for trusted connections

#import "ClassCon.h"
//  For now, I've hard coded the IP address of my trusted server.
#define TRUSTED_HOST @"192.168.1.2"

@implementation ClassCon {
    NSMutableData *contentData;
    NSURLConnection *conn;
}

-(void) loadContent {
    contentData = [NSMutableData data];
    NSString *contentURL = @"our url";
    conn = [[NSURLConnection alloc] initWithRequest:
            [NSURLRequest requestWithURL:[NSURL URLWithString:contentURL]] delegate:self];

}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [contentData appendData:data];
}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    NSLog(@"Bad: %@", [error description]);
    ContentResponse *response = [[ContentResponse alloc]initWithRc:-999 andDescr:@"error" andAction:0];

    conn = nil;
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
        NSString *loadedContent = [[NSString alloc] initWithData:
                                     contentData encoding:NSUTF8StringEncoding];
        NSLog(@"Loaded content: %@",loadedContent);

    }

// ------------ ByPass ssl starts ----------
-(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:
(NSURLProtectionSpace *)protectionSpace {
    return [protectionSpace.authenticationMethod
            isEqualToString:NSURLAuthenticationMethodServerTrust];
}

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:
(NSURLAuthenticationChallenge *)challenge {
    if (([challenge.protectionSpace.authenticationMethod
          isEqualToString:NSURLAuthenticationMethodServerTrust])) {
        if ([challenge.protectionSpace.host isEqualToString:TRUSTED_HOST]) {
            NSLog(@"Allowing bypass...");
            NSURLCredential *credential = [NSURLCredential credentialForTrust:
                                           challenge.protectionSpace.serverTrust];
            [challenge.sender useCredential:credential
                 forAuthenticationChallenge:challenge];
        }
    }
    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
// -------------------ByPass ssl ends

uiwebview not working with HTTP or HTTPS urls

Try this:

webPage.userInteractionEnabled = YES;

UIWebView won't load links with certificate (https:// prefix)

Fixed my issue, I was able to load https with no problem with the following code I didn't think this would work but it does!:

NSURLRequest *req = [NSURLRequest requestWithURL:mURL];
urlConnection=[[NSURLConnection alloc] initWithRequest:req delegate:self];
webView.scalesPageToFit = YES;
[webView loadRequest:req];

How to load URL in UIWebView in Swift?

loadRequest: is an instance method, not a class method. You should be attempting to call this method with an instance of UIWebview as the receiver, not the class itself.

webviewInstance.loadRequest(NSURLRequest(URL: NSURL(string: "google.ca")!))

However, as @radex correctly points out below, you can also take advantage of currying to call the function like this:

UIWebView.loadRequest(webviewInstance)(NSURLRequest(URL: NSURL(string: "google.ca")!))   

Swift 5

webviewInstance.load(NSURLRequest(url: NSURL(string: "google.ca")! as URL) as URLRequest)
