I'm trying to programmatically (using gdata api) retrieve incoming messages from youtube account.
My request:
NSURL *url = [NSURL URLWithString:#"http://gdata.youtube.com/feeds/api/users/my_nick/inbox"];
NSMutableURLRequest *inboxRequest = [NSMutableURLRequest requestWithURL:url];
NSString *authStr = [NSString stringWithFormat:#"GoogleLogin auth=%#", authMarker];
[inboxRequest setValue:authStr forHTTPHeaderField:#"Authorization"];
[inboxRequest addValue:#"Content-Type" forHTTPHeaderField:#"application/x-www-form-urlencoded"];
[inboxRequest setHTTPMethod:#"GET"];
NSHTTPURLResponse *response = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:inboxRequest returningResponse:&response error:nil];
NSString *responseDataString = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];
NSLog(#"\n%#\n", responseDataString);
NSLog(#"\n%#\n", [inboxRequest ]);
return feed without entries... (although I can see incoming messages on the site)
here response from nslog:
<?xml version='1.0' encoding='UTF-8'?><feed xmlns='http://www.w3.org/2005/Atom' xmlns:openSearch='http://a9.com/-/spec/opensearchrss/1.0/'><id>http://gdata.youtube.com/feeds/api/users/thisistestnick/inbox</id><updated>2011-06-16T14:45:00.475Z</updated><category scheme='http://schemas.google.com/g/2005#kind' term='http://gdata.youtube.com/schemas/2007#videoMessage'/><title type='text'>Inbox of thisistestnick</title><logo>http://www.youtube.com/img/pic_youtubelogo_123x63.gif</logo><link rel='alternate' type='text/html' href='http://www.youtube.com/my_messages?folder=inbox&filter=videos'/><link rel='http://schemas.google.com/g/2005#feed' type='application/atom+xml' href='http://gdata.youtube.com/feeds/api/users/thisistestnick/inbox'/><link rel='http://schemas.google.com/g/2005#batch' type='application/atom+xml' href='http://gdata.youtube.com/feeds/api/users/thisistestnick/inbox/batch'/><link rel='self' type='application/atom+xml' href='http://gdata.youtube.com/feeds/api/users/thisistestnick/inbox?start-index=1&max-results=25'/><author><name>thisistestnick</name><uri>http://gdata.youtube.com/feeds/api/users/thisistestnick</uri></author><generator version='2.0' uri='http://gdata.youtube.com/'>YouTube data API</generator><openSearch:totalResults>0</openSearch:totalResults><openSearch:startIndex>1</openSearch:startIndex><openSearch:itemsPerPage>25</openSearch:itemsPerPage></feed>
what is wrong? pls help.
Why cant you use, gdata-objectivec lib api's rather doing your own parsing ? I havent tried retrieving 'inbox' but was fairly successful in getting the info i want. Advantages of using it are:
a) You get the info in native formats (Strings and Dictionaries), lib does the job of parsing feeds for you.
b) mainly, there wont be any parsing/api understanding errors (which i suppose is the reason for your problem).

I am trying to post an image to reddit; however, I only kind of know what I am doing. I am using objective c for my iphone app.
Prior to the code listed below I obtain a modhash and cookie by logging in prior to the upload and use NSLog to determine that I truly am receiving them. Then I use a JSON Parser to separate them into separate variables.
I was not sure what all of the POST argument values were supposed to be so I kind of guessed. The necessary arguments are uh, file, formid, header, ing_type, name, and sponsor.
The documentation for reddit api is http://www.reddit.com/dev/api I believe that I want to use the POST /api/upload_sr_img method...
NSURL *url = [NSURL URLWithString:#"http://www.reddit.com/api/upload_sr_img"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:#"POST"];
NSString *httpBody = [NSString stringWithFormat:#"?uh=%#&file=%#&formid=''header=%#&img_type=%#&name=%#&sponsor=%#",modhash,UIImagePNGRepresentation(self.memeImage.image),#"test",#"png",#"Drew",#"Drew'sApp"];
[request setHTTPBody:[httpBody dataUsingEncoding:NSASCIIStringEncoding]];
NSURLResponse *response = NULL;
NSError *imgError = NULL;
NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&imgError];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:result options:NSJSONReadingMutableContainers error:nil];
NSDictionary *responseJson = [json valueForKey:#"json"];
NSLog(#"response is: %#",response);
NSLog(#"imgError is: %#",imgError);
NSLog(#"result is: %#",result);
NSLog(#"json is: %#",json);
NSLog(#"responseJson is: %#",responseJson);
Could use any help I can get.
Also, I was not sure if I needed to send a content-type or even what it would be.
Thanks for your help.

I am trying to send a query as part a the URL to obtain an XML file, and then trying to parse the XML file using NSXMLParser and initWithContentsOfURL. However the parser is not able to parse the file. I tested the parser with the same file, but this time the file was saved on the server (it was not being generated) and it worked just fine, so I know it is not a problem with the parser.
I have come to think that it does not parse it because I need to load the file before I try to parse it, or give the initWithContentsOfURL time to load the contents. So I tried to put those contents in a NSString and a NSData and using a sleep function as well as using a block but that did not work either.
What would be the best way to go about this problem?
Here is some of the code:
NSString *surl = [NSString stringWithFormat:#"http://lxsrv7.oru.edu/~maria_hernandez/query.xml"];
url = [NSURL URLWithString:surl];
NSString *curl = [[NSString alloc] initWithContentsOfURL:url];
NSLog(#"URL: %#", surl);
NSLog(#"URL Content: %#", curl);
SXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:receivedData];
//Other stuff we have tried:
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:surl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSURLResponse = nil;
NSError = nil;
receivedData = [NSURLConnection sendSynchronousRequest: theRequest returningResponse: &theResponse error: &error];
Let me know if you have more questions or if you wish to see more code.
Thanks!
have you tried setting a delegate for the NSXMLParse that implements the NSXMLParserDelegate which has events for parsing the document

I'm rather new to trying to figure out how JSON and the DropBox API function with the iphone SDK that DB has release for the iPhone. I understand how both technologies work in general and that you have to build a dictionary into a request and get another dictionary back, but I can't find a solid example of how to do anything specifically enough online in Objective C.
I just need one example of how to retrieve for instance the user's profile information by creating a JSON request to fetch info from the drop-box server.
I've been able to log the user in and linking the device using the consumer key and consumer secret but what's next I'm a little at a loss.
MANY thanks for any guidance or examples.
To send your data
Example for POST methods:
url = #"https://api.dropbox.com/<version>/account/"
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:value forKey:#"callback"];
Example for GET methods (URL queries):
NSString *urlString = [[[NSString alloc] initWithString:#"https://api.dropbox.com/<version>/account/info
"] autorelease];
urlString = [urlString stringByAppendingFormat:#"?callback=whatever&status_in_response=something"];
NSURL *url = [[NSURL alloc] initWithString:urlString];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:#selector(requestDidFinishForThreadID:)];
[request startAsynchronous];
To retrieve JSON values and convert them into Dictionary
SBJsonParser *json = [[SBJsonParser alloc] init];
NSDictionary *dict = (NSDictionary*)[json objectWithString:responseString];
You will need JSON Framework: http://code.google.com/p/json-framework/
And also ASIHTTPRequest: http://allseeing-i.com/ASIHTTPRequest/
Haven't tested it with dropbox, but should be this way.
I am trying to parse a JSON response of a GET request. When the characters, are latin no problem.
However when they are not latin the message doesn't come out correctly. I tried greek and instead of "πανος" i get "& pi; & alpha; & nu; & omicron; & sigmaf;"
The code I use for parsing the response is:
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"response %#", responseString);
// array from the JSON string
NSArray *results = [responseString JSONValue];
When I try to read the response from a website using ajax, everything is fine. The same applies when trying to send a GET request to the application servers with data from iphone. So when i transmit data to the server and read it from the website everything is fine. When i try to show the same data in the app, "Houston we have a problem".
Any clues?
EDIT: To avoid misunderstandings, it's not an issue of HTML, I just point out that for some readon utf-8 characters here are encoded correctly and automatically eg. "&pi" will be converted to "π", however objective c doesn't seem to do this on its own
There is a confusion I think.
π is an HTML entity which is unrelated to text encoding like UTF8 / Latin.
Read wikipedia for details about...
You need a parser to decode these entities like the one previously mentioned by Chiefly Izzy:
NSString+HTML category and method stringByReplacingHTMLEntities
Look at Cocoanetics NSString+HTML category and method stringByReplacingHTMLEntities method. You can find it at:
https://github.com/Cocoanetics/NSAttributedString-Additions-for-HTML/blob/master/Classes/NSString%2BHTML.m
Here's a pretty decent list of lot of HTML entities and their corresponding unicode characters.
Try to use this snippet of code:
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSString *decodedString = [NSString stringWithUTF8String:[responseString cStringUsingEncoding:[NSString defaultCStringEncoding]]];
NSLog(#"response %#", decodedString);
// array from the JSON string
NSArray *results = [decodedString JSONValue];
I have faced the same problem, but I solved it by changing the JSON parser. I have started using the SBJSONParser, and now I am getting the appropriate results. This is the code snippet, I have used
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
SBJSON *parser=[[SBJSON alloc]init];
NSArray *JSONData = (NSArray*)[parser objectWithString:returnString error:nil];
Whats the best way to make this a more secure and less obvious security risk?
NSString *loginIdentification = [NSString stringWithFormat:#"user=%#&pass=%#&", userNameLogin, passWordLogin];
addressVariable = [NSString stringWithFormat:#"%#/%#", url, loginIdentification];
addressVariable = [addressVariable stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSURLResponse* response = nil;
NSError* error = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
Make sure you're using an https connection and not an http connection.
Instead of putting the sensitive information in the URL (via GET), use the POST method and put them in the body. That way, they won't show up in your server logs.
