I want to follow a twitter user on a button click. I used the share kit follow me method using oauth. But always I am getting this error.
{"error":"Could not authenticate with
OAuth.","request":"/1/friendships/create/priyankav89.json"}
Then I tried to implement it myself
NSURL *url = [NSURL URLWithString:#"https://api.twitter.com/1/friendships/create.json"];
NSMutableDictionary *dict=[[NSMutableDictionary alloc]init];
[dict setObject:#"871252998" forKey:#"user_id"];
[dict setObject:#"true" forKey:#"follow"];
[dict setObject:#"KXL0jFLJY6RI4lszOz8r5w" forKey:#"consumer"];
NSString *jsonRepresentation=[dict JSONString];
NSLog(#"jsonRepresentation = %#",jsonRepresentation);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:3];
NSData *postData=[NSData dataWithBytes:jsonRepresentation.UTF8String length:[jsonRepresentation length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [postData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLResponse *response;
NSError *error=nil;
NSData *responseData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"respon = %s",responseData.bytes);
still I am getting the same error.
I searched a lot. Still no use. I don't want to load the url in a UIWebView or in safari. I want to support the app from ios4. So ios5 built-in twitter app cannot be used.
I found the problem. In share kit follow me method they are not calling the authorization method before following. So we want to call authorize before login and save the access token.
Assuming you know how to tweet using the twitter integrated to the iOS, you can simply tweet "follow "

I've done many searches but none of the code fragments I find seem to work for me. I have the following fragment in xcode for running within my iPhone app:
NSURL *url = [NSURL URLWithString:#"http://blah.blah.com/rec.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
NSData *body = [#"data=crap" dataUsingEncoding:NSUTF8StringEncoding];
NSString *bodyLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:bodyLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:body];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL];
The rec.php is called fine but the post data does not make it through. The entry $_POST['data'] is empty. Could anyone let me know what I'm doing wrong?
I'm trying to manipulate this curl request in Objective-C:
curl -u username:password "http://www.example.com/myapi/getdata"
I've implemented the following and I'm getting a data get error Domain=kCFErrorDomainCFNetwork Code=303 with NSErrorFailingURLKey=http://www.example.com/myapi/getdata:
// Make a call to the API to pull out the categories
NSURL *url = [NSURL URLWithString:#"http://www.example.com/myapi/getdata"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
// Create the username:password string for the request
NSString *loginString = [NSString stringWithFormat:#"%#:%#", API_USERNAME, API_PASSWORD];
// Create the authorisation string from the username password string
NSData *postData = [loginString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
[request setURL:url];
[request setHTTPMethod:#"GET"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
I was hoping that someone could spot where I am going wrong with my attempt to manipulate the curl request and point me in the correct direction. Is there something obvious I'm missing out? The data returned from the API is in a JSON format.
I found that the best thing to do was to not attempt the authentication within the code and to put it straight in the URL itself. The working code looks as follows:
NSURL *url = [NSURL URLWithString: [NSString stringWithFormat:#"http://%#:%##www.example.com/myapi/getdata", API_USERNAME, API_PASSWORD]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setURL:url];
[request setHTTPMethod:#"GET"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSError *error;
NSURLResponse *response;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
This guide seems to do what you're looking for:

Just as an FYI, a lot of classes accept initWithData, and NSData has a method dataWithContentsOfURL, if you want to avoid setting up NSURLConnections yourself this could be an easier way of achieving what you're looking for.
I have below code for posting data to the web server but it gives me null response, I have multiple data and they are:-

Thanks in advance.
Here is an article which demonstrates how to consume .NET Web service using iOS application. You can use the techniques discussed in the article:
http://www.highoncoding.com/Articles/809_Consuming__NET_Web_Services_in_an_iOS_Application.aspx
Almost all the work I do involves .NET with iOS. Have a look here for the network class I wrote and use all the time (AFNetworking based). I prefer to use a regular aspx form instead of an asmx web-service. I do this because I don't want to expose any web-methods to snooping visitors and I use an API key check before returning anything in the aspx form. I can send you an example .NET code (written in VB.NET) if you need me to.
I would like to ask about the button and the url post method in iPhone application.
In my program, I want the user to click a button, and then a url will be called by POST method. For the url, it may need to redirect to somewhere (302 or 303) etc and final is 200.
I have complete the button and the success page, however, I don't know how to use the objective-C library. I found lots of reference of this forum, but I don't understand what the code means. Can anyone help me?
The following is a question which I believe related to the question.
Invoking a http post URL from iphone using .net web service
Thank you very much.
If you're okay with blocking the thread you're making the request on, this is just about as simple as it gets.
NSString *postBody = [NSString stringWithFormat:#"param1=%#¶m2", param1value, param2value];
NSData *postData = [postBody dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:targetURL];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
A few caveats:
This will perform a synchronous (blocking) request, so either do it on a background thread or look into using the NSURLConnection delegate methods.
POST data must be URL-encoded, so you may need to do some preprocessing of your parameter values.
Redirects will occur automatically until a 200 OK or an error is encountered.
I am creating an app for the iPhone that fetches a specific page from a website, but to be able to view this site you need to log in with a username and a password.
I've created this code:
NSString *urlAddress = #"http://www.wdg-hamburg.de";
NSURL *url = [NSURL URLWithString:urlAddress];
NSString *post = #"name=loginname&pass=pass&form_id=user_login&op=Anmelden";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod: #"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
[vPlan loadRequest:request];
But I am not logged in at the UIWebView!
I am logging NSHTTPCookieStorage to the console and it shows me the necessary cookie, but I dont get logged in.
Does anybody knows how I can fix that?
Kind regards,
A. Miladinovic
Have you tried setting the cookie in the header?
NSArray* cookies = [NSArray arrayWithObjects: cookie, nil];
NSDictionary * headers = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];
[request setAllHTTPHeaderFields:headers];
