I know this has been asked before but I have looked at every answer (there aren't many) and none help me.
The issue I am running into is dealing with certificates with my schools e-mail service. The links for the two e-mail services are here:
Main school e-mail:
https://marauder.millersville.edu/mail/index.pl
Computer Science e-mail:
https://cs.millersville.edu/cswebmail
University student portal (Marauder Mail button on the right doesn't open when clicked in my UIWebView)
http://myville.millersville.edu/
At first neither of the websites would load in my UIWebView using a standard NSURL and NSURLRequest. I looked
on the web for a solution and someone suggested using the NSURLProtocolClient delegate methods. After
implementing them, my UIWebView will now load the schools mail e-mail ONLY when I have a button that when
clicked opens the link directly, as opposed to trying to access the mail from the portal site (3rd link above), and it
still never loads the computer science e-mail link. I have scoured the iOS help sites, posted questions, tried
multiple open-source custom UIWebViews, but I have not found anything that works.
Most answers I have read around the web point to ASIHTTPRequest. I have tried this but I cannot implement it right, it doesn't load the links in my UIWebView; here is my code for how I am loading a link:
mURL = [self getURL:viewNumber];
ASIHTTPRequest *req = [ASIHTTPRequest requestWithURL:mURL];
[req setDelegate:self];
[req startSynchronous];
//NSURLRequest *req = [NSURLRequest requestWithURL:mURL];
//urlConnection=[[NSURLConnection alloc] initWithRequest:req delegate:self];
webView.scalesPageToFit = YES;
//[webView loadRequest:req];
Code in comments is how I load a link without ASIHTTPRequest.
Any help is appreciated!
Also, I have another issue with my UIWebView, link is below. I haven't had any answers so if you're bored please check it out:
UIWebView doesn't detect text box on website
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];
Web view does not load https urls due to certificate mismatch. After writing this extension it would work as expected
Swift 2.2
extension NSURLRequest {
static func allowsAnyHTTPSCertificateForHost(host: String) -> Bool
{
return true
}
}

In my browser based application, I need to set a proxy for each url and doing this with the help of ASIHTTPRequest.
The problem I am facing is that the web view is taking double the time to load the page, probably because I am loading the page twice in my code.
First I check the status with ASIHTTPRequest to determine if the page is allowed to load by ASIHTTPRequest and if so, then I load that url on web-view.
This is where I think the problem is as I think I am loading the url two times which is consuming time.
Can you make a suggestion on other ways to load page once, but in a way that supports checking for authenticated page with usage of proxy settings, or provide me with a link to guide relevant to this question?
NSString *response = [NSString stringWithContentsOfFile:
[theRequest downloadDestinationPath] encoding:[theRequest responseEncoding] error:nil];
int statusCode = [requestH responseStatusCode];
if (statusCode == 200) {
[webV loadRequest:[NSURLRequest requestWithURL:[requestH url]]];
}
else {
[webV loadHTMLString:response baseURL:[theRequest url]];
}
Implement the delegate methods of NSURLConnection (apple docu) and in the connectionDidFinishLoading save the content of the url to a local file and then in load this local file with loadHTMLString.
I want to open an URL which need password and username in a UIWebview. Such as open my local Wifi Router(192.168.1.1). But when I try following code, there is no popup as Safari to require password and username.
NSURL *url = [NSURL URLWithString:#"http://192.168.1.1"];
NSURLRequest *httpReq = [NSURLRequest requestWithURL:url];
[self._webView loadRequest:httpReq];
Since someone told me to use NSURLConnectionDelegate, I know this, but I donot know how to show the authorized page to the UIWebView.
This will help
NSURL *url = [NSURL URLWithString:#"http://username:password#192.168.1.1"];
NSURLRequest *httpReq = [NSURLRequest requestWithURL:url];
[self._webView loadRequest:httpReq];
You need to implement connection:didReceiveAuthenticationChallenge: in NSURLConnectionDelegate. For details, read Authentication Challenges chapter from Apple "URL Loading System Programming Guide".
UIWebView doesn't provide any mechanism to identify the response. So one solution is explained in UIWebViewHttpStatusCodeHandling github project which identifies the status code of the response (should be 404 in your case).
However, the main drawback is for each request you need to use NSURLConnection and load the request again. But in this case, you can cancel the NSURLConnection too.
The other solution should (might) be the use of Java-Script. Search for the Java-script, which provides the status code of the response.
I'd like to know if it was possible, if a user wishes to subscribe to updates of my applications, take a form that is automatically subscribed to this newsletter at this address http://www.gseo.it/lists/?p=subscribe&id=2 (this is my mailing list with double opt in) but I'd like to know that a user can subscibe this newsletter directly from my iphone app.
Thanks
You could do an HTTP POST to that form using ASIFormDataRequest.
This isn't working code, but it might look something like:
NSURL *url = [NSURL URLWithString:#"http://www.gseo.it/lists/?p=subscribe&id=2"];
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease];
[request setPostValue:#"someone#example.com" forKey:#"email"];
[request startSynchronous];
You can get the library here.
Yes of course you can, open up a UIWebview with the the url provided. Don't forget that this may look not good in the iphone browser so providing a custom html code depending on the user agent may improve things.
I'm trying to track an event in my app using Yahoo Web Analytics. The code I am using looks like
ASIHTTPRequest *yahooTrack = [ASIHTTPRequest requestWithURL:
[NSURL URLWithString:#"http://s.analytics.yahoo.com/p.pl?a=xxxxxxxxxxxxx&js=no&b=yyyyyyyyyyyy&cf6=zzzzzzzzzzz"]];
yahooTrack.didFinishSelector = #selector(statisticsFinished:);
yahooTrack.delegate = self;
[yahooTrack startAsynchronous];
Then the statisticsFinished looks like:
NSLog(#"Cookies: %#", request.requestCookies);
NSLog(#"Redircount: %d", [request redirectCount]);
NSLog(#"Responsecode %d %#\nMsg: %#", request.responseStatusCode,
request.responseStatusMessage, [request responseString]);
And all the information I get back looks correct. Cookies are set, redirectcount is 1 the first time (as it redirects to s.analytics.yahoo.com/itr.pl?.... a normal browser does). Then the redirectcount is 0 for subsequent request until the app is restarted and session cleared. The responseString returns GIF89a.
Even if the data looks correct, Yahoo still won't track. As soon as I call the tracking url directly in my browser it works as expected.
I realize Flurry is a better option, but I'm forced to use Yahoo in this case. Also, using a UIWebView probably would work, but I'm against putting in a webview just for tracking purposes.
Is there any difference in how ASIHTTPRequest and Safari would handle a call to a simple URL as this? Or do you see anything else that could explain why the tracking isn't working?
I finally found the problem. ASIHTTPRequest creates a user-agent based on your applications name, and requests from this user agent is ignored by Yahoo somehow (bug?). As stated in the documentation, you can override the user-agent as follows:
[request addRequestHeader:#"User-Agent" value:#"My-User-Agent-1.0"];
I used the user-agent string of Safari on iPhone, and it worked immediately! BTW; the same problem applies for Android, and the same fix works.
It seems the only way to stay "in app" is to give them a UIWebView of the paypal mobile site and let them complete the transaction there, otherwise the user would need to use their API key.
Does this sound right and has anyone got or seen any sample code? I have to think this is a common piece of code.
UPDATE:
Will Apple allow this?
It is a charity app, so I am assuming there is no issue.
Re-UPDATE:
I assumed wrong.
Apple will not allow payments directly within apps using paypal. You have to re-direct to a web interface.
Re-Update:
As answered below this code may still be useful for the purchase of physical goods
Update:
Although this code works, App Store terms won't allow you to use this code within an app.
Original Answer:
I figured this out after some heavy API research. Below is a method that creates an HTTP POST to send to Paypal and makes an NSURLRequest. You can fill in the appropriate string format variables. I used HTTP Client to check what I was doing.
- (void)sendPayPalRequestPOST{
perfomingSetMobileCheckout=YES;
recordResults = FALSE;
NSString *parameterString = [NSString stringWithFormat:#"USER=%#&PWD=%#&SIGNATURE=%#&VERSION=57.0&METHOD=SetMobileCheckout&AMT=%.2f&CURRENCYCODE=USD&DESC=%#&RETURNURL=%#", userName, password, signature, self.donationAmount, #"Some Charge", returnCallURL];
NSLog(parameterString);
NSURL *url = [NSURL URLWithString:paypalUrlNVP];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:#"%d", [parameterString length]];
[theRequest addValue: msgLength forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPMethod:#"POST"];
[theRequest setHTTPBody: [parameterString dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if( theConnection ){
webData = [[NSMutableData data] retain];
[self displayConnectingView];
}else{
NSLog(#"theConnection is NULL");
}
}
After this you need to parse the response, grab the session key and create a UIWebView to take them to the mobile paypal site. Paypal lets you specify a "return URL" which you can make anything you want. Just keep checking the UIWebview in the delegate method for this address and then you know the transaction is complete.
Then you send one more HTTP Post (similar to the one above) to Paypal to finalize the transaction. You can find the API information in the Paypal Mobile Checkout API docs.
Apple will allow custom checkouts for physical purchases. I talked with them at the iPhone Tech Talks in London and they said that they will not support physical purchases with In App Purchase as they would have to deal with refunds, etc. They also referred to existing apps that have custom checkouts.
When you say "I assumed wrong" about Apple allowing charitable donations within an app, can you provide any more information? I'm working on an app and there's a requirement to allow charitable donations...I haven't been able to find anything from Apple strictly forbidding it, but I haven't been able to find an app that allows charitable donations in the store, either.
(I struggled with whether to post this here and not as a new top-level question, but you're the first person I've come across with direct knowledge about the charitable giving within an iPhone app question).
Is it not possible using Paypal's Mobile Payment Library?
https://www.x.com/community/ppx/xspaces/mobile/mep?view=overview
Depending on the complexity of your needs, PayPal's iOS SDK (released March 2013) might be the ticket.
