} else {

NSLog(#"at parser %#", xmlparser);
[parser setDelegate:self];
The last line of the code is showing me error and suggest that "change parser to pause"!! Please help!!
Well, isn't that because your parser variable is named 'xmlparser' and not 'parser' ?
Change parser to xmlparser.

I'm trying to implement this example link of a DocuSign service that download an envelope document, but when the execution arrive to this line in step 3:
NSMutableString *jsonResponse = [[NSMutableString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
jsonResponse is nil and when I open the document, it has a lot of strange characters and I can't read it.
My code for downloadind is the following:
NSString *url = #"https://demo.docusign.net/restapi/v2/accounts/373577/envelopes/08016140-e4dc-4697-8146-f8ce801abf92/documents/1";
NSMutableURLRequest *documentsRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
[documentsRequest setHTTPMethod:#"GET"];
[documentsRequest setURL:[NSURL URLWithString:url]];
[documentsRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[documentsRequest setValue:[self jsonStringFromObject:authenticationHeader] forHTTPHeaderField:#"X-DocuSign-Authentication"];
NSError *error1 = [[NSError alloc] init];
NSHTTPURLResponse *responseCode = nil;
NSData *oResponseData = [NSURLConnection sendSynchronousRequest:documentsRequest returningResponse:&responseCode error:&error1];
NSMutableString *jsonResponse = [[NSMutableString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
if([responseCode statusCode] != 200){
NSLog(#"Error sending %# request to %#\nHTTP status code = %i", [documentsRequest HTTPMethod], url, [responseCode statusCode]);
NSLog( #"Response = %#", jsonResponse );
return;
}
// download the document to the same directory as this app
NSString *appDirectory = [[[NSBundle mainBundle] bundlePath] stringByDeletingLastPathComponent];
NSMutableString *filePath = [NSMutableString stringWithFormat:#"%#/%#", appDirectory, #"eee"];
[oResponseData writeToFile:filePath atomically:YES];
NSLog(#"Envelope document - %# - has been downloaded to %#\n", #"eee", filePath);
If no data is coming back from
NSMutableString *jsonResponse = [[NSMutableString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
then that means oResponseData is most likely nil which means the URL is not being constructed correctly for each envelope document. Are you doing step 2 in the sample that you linked to, where it first retrieves the envelopeDocuments information about the envelope, then it dynamically builds each unique document uri in preparation of downloading each one.
Instead of hardcoding your URL you should dynamically retrieve the envelopeDocuments data, then build each document uri dynamically then your response data will not be nil. Here's the full working sample:
- (void)getDocumentInfoAndDownloadDocuments
{
// Enter your info:
NSString *email = #"<#email#>";
NSString *password = #"<#password#>";
NSString *integratorKey = #"<#integratorKey#>";
// need to copy a valid envelopeId from your account

if i cookie allowed then csrf token validation issue comes
and when i cookie not allowed then csrf token issue not comes ....how to resolved issue..thanks

I know this is a bit of an old thread. But you should check out https://github.com/kylebrowning/drupal-ios-sdk as well as AFNetworking. You're really working way harder than you have to.
But to answer your question, once you log in, the CSRF token will be returned in the user object and will be valid for then entire user session. So you can cache it and use it until the user logs out or their session expires.
With Drupal IOS SDK it is as simple as:
[DIOSUser userMakeSureUserIsLoggedInWithUsername:username
andPassword:password
success:^(AFHTTPRequestOperation *op, id response) {
DLog(#"user: %#", response);
[DIOSSession sharedSession].user = response;
//NOTE: fix for services 3.4+ CSRF Token Validation
[[DIOSSession sharedSession] setDefaultHeader:#"X-CSRF-Token" value:response[#"token"]];
[self saveLoginInfoForUserWithUsername:username andPassword:password];
[self processUserInfoWithUser:response];
success(response);
}
failure:^(AFHTTPRequestOperation *op, NSError *err) {
failure(err);
}
];
I have this link :
function new_message($chat_id,$user_id,$message,$recipient_ids)
http://www.demii.com/demo/dooponz/admin/index.php/chat/new_message/4/1/you/2%2C7
return chat_log_id
Can anyone please explain me how to call webserive by this get method or give me the
solution .
what i did with my code is below :
-(void)newMessage{
if ([self connectedToWiFi]){
NSString *urlString = [NSString stringWithFormat:#"www.demii.com/demo/dooponz/admin/index.php/chat/new_message/4/1/you/1,1,2"];
NSLog(#"urlString is %#", urlString);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *requestURL = [NSURL URLWithString:urlString];
[request setURL:requestURL];
[request setHTTPMethod:#"POST"];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSLog(#"ERROR = %#",error.localizedDescription);
if(error.localizedDescription == NULL)
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> succ %#",returnString);
[delegate ConnectionDidFinishLoading:returnString : #"newMessage"];
}
else
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> fail %#",returnString);
[delegate ConnectiondidFailWithError:returnString : #"newMessage"];
}
}];
}
}
how can i handle this ?
Thanks in advance .
I am not sure from your post whether or not you want to "post" or "get." However, gauging from the fact that you set your method to post, and that you are creating something new on your server, I am assuming you want to post.
If you want to post you can use my wrapper method for a post request.
+ (NSData *) myPostRequest: (NSString *) requestString withURL: (NSURL *) url{
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setTimeoutInterval:15.0];
NSData *requestBody = [requestString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
[request setHTTPBody:requestBody];
NSURLResponse *response = NULL;
NSError *requestError = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError];
return responseData;
}
Where request string is formatted like this:
NSString * requestString = [[NSString alloc] initWithFormat:#"username=%#&password=%#", userInfo[#"username"], userInfo[#"password"]];
This will also shoot back the response data which you can turn into a string like this.
responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
If you are trying to grab data from the server in json format...
+ (NSArray *) myGetRequest: (NSURL *) url{
NSArray *json = [[NSArray alloc] init];
NSData* data = [NSData dataWithContentsOfURL:
url];
NSError *error;
if (data)
json = [[NSArray alloc] initWithArray:[NSJSONSerialization
JSONObjectWithData:data
options:kNilOptions
error:&error]];
//NSLog(#"get results: \n %#", json);
return json;
}
Pls change ur code like this
-(void)newMessage{
NSString *urlString = [NSString stringWithFormat:#"http://www.demii.com/demo/dooponz/admin/index.php/chat/new_message/4/1/you/27" ];
NSLog(#"urlString is %#", urlString);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *requestURL = [NSURL URLWithString:urlString];
[request setURL:requestURL];
[request setHTTPMethod:#"POST"];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSLog(#"ERROR = %#",error.localizedDescription);
if(error.localizedDescription == NULL)
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> succ %#",returnString);
[self parseStringtoJSON:data];
//[delegate ConnectionDidFinishLoading:returnString : #"newMessage"];
}
else
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> fail %#",returnString);
// [delegate ConnectiondidFailWithError:returnString : #"newMessage"];
}
}];
}
-(void)parseStringtoJSON:(NSData *)data{
NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
NSLog(#"chat id %#",[dict objectForKey:#"chat_log_id"]);
}
u will get the JSON response string as result if u hit that url. If u r familiar with json parsing, u can get the value based on key.
see this link: How do I deserialize a JSON string into an NSDictionary? (For iOS 5+)
I have written code like this but I can't understand how to find if the data is present or not in the URL. Can anyone help me in solving this problem?
Note: This code terminates when the loop is entering the second condition. That is where it's terminating.
-(void)getdetails
{
NSLog(#"in get details");
NSURL *jsonurl=[NSURL URLWithString:#"http://www.myappdemo.com/checkout/services/getonlineusers.php"];
NSMutableURLRequest *request=[[[NSMutableURLRequest alloc]init ]autorelease];
[request setURL:jsonurl];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSError *error;
NSURLResponse *response;
NSData *serverReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *replyString = [[NSString alloc] initWithBytes:[serverReply bytes] length:[serverReply length] encoding: NSASCIIStringEncoding];
if([replyString isEqualToString:#"Invalid."]){ // i have not set the php code to output "invalid" so this will not work for now ...
NSLog(#"%#",replyString);
}
else {
NSMutableArray *tempArray =[replyString JSONValue];
int count=0;
self.temparray=tempArray;
for(int i=0;i<[tempArray count];i++)
{
///////Here in this loop when it is entering it is terminating /////////
NSDictionary *dict=[tempArray objectAtIndex:i];
NSLog(#"DICT is %#",dict);
NSString *string=[dict objectForKey:#"profilepic"];
NSURL *finalURL = [NSURL URLWithString:[string stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
NSLog(#"encoding string is %#",finalURL);
NSURL *url=[NSURL URLWithString:string];
NSString *source = [NSString stringWithContentsOfURL:finalURL encoding:NSUTF8StringEncoding error:nil];
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:url];
NSLog(#"url is %#",url);
NSData *data=[NSData dataWithContentsOfURL:url];
if(!(data==nil))
{
NSLog(#"data is there");
UIImage *image=[[UIImage alloc]initWithData:data];
[self.array addObject:image];
[image release];
}
else {
/*
NSLog(#"if data is null condition block");
UIImage *image=[[UIImage alloc]init];
[self.array addObject:image];
[image release];
*/
}
count=count+1;
NSLog(#"count is %d",count);
}
}
[replyString release];
}
Where does the app terminate and what is the exception? Have you stepped through to see what the array object looks like during each iteration? Is it failing at NSData initWithContentsOfURL? Why don't you issue that as a separate synchronous request and test to see if you got a response?
Regarding your first (and any subsequent) synchronous request, it would probably be good to add a check to ensure you received a valid response (sorry for the formatting, the code tag isn't playing nicely at the moment)
if (response!=nil) {if([response isKindOfClass:[NSHTTPURLResponse class]]) {
// you have a valid response }}
I am developing an app using data from google reader's API and using GData for login.
I want to be able to mark a post inside a table cell as read / unread, but am finding the fact that this is all mainly undocumented hard to work out a solution, any ideas / links?
Here is the code for the mark read button:
//Get the token
NSString *tokenString = [NSString stringWithFormat:#"https://www.google.com/reader/api/0/token"];
NSURL *tokenURL = [NSURL URLWithString:tokenString];
NSMutableURLRequest *tokenRequest = [NSMutableURLRequest requestWithURL:tokenURL];
NSString *tokenStringResult;
NSArray *listItems;
NSError *tokenError = nil;
NSURLResponse *tokenResponse = nil;
NSData *tokenData = [NSURLConnection sendSynchronousRequest:tokenRequest
returningResponse:&tokenResponse
error:&tokenError];
if (tokenData)
{
tokenStringResult = [[NSString alloc] initWithData:tokenData encoding:NSUTF8StringEncoding];
listItems = [tokenStringResult componentsSeparatedByString:#"/"];
}
else
{
NSLog(#"tokenError = %#", tokenError);
}
// Mark it as read
NSString *readerURLString = [NSString stringWithFormat:#"http://www.google.com/reader/api/0/edit-tag?a=user/-/state/com.google/read&async=true&s=feed/%#&i=%#&T=%#", siteLink, postID, [listItems lastObject]];
NSURL *readerURL = [NSURL URLWithString:readerURLString];
NSMutableURLRequest *readerRequest = [NSMutableURLRequest requestWithURL:readerURL];
[mAuth authorizeRequest:readerRequest];
NSError *error = nil;
NSURLResponse *response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:readerRequest
returningResponse:&response
error:&error];
if (data)
{
NSHTTPURLResponse * httpResponse = (NSHTTPURLResponse *) response;
assert( [httpResponse isKindOfClass:[NSHTTPURLResponse class]] );
NSLog(#"response.allHeaderFields = %#", [httpResponse allHeaderFields]);
NSLog(#"response.statusCode = %i", [httpResponse statusCode]);
}
the log from this is:
response.statusCode = {
"Cache-Control" = "private, max-age=0";
"Content-Length" = 1334;
"Content-Type" = "text/html; charset=UTF-8";
Date = "Fri, 21 Jan 2011 03:49:07 GMT";
Expires = "Fri, 21 Jan 2011 03:49:07 GMT";
Server = GSE;
"X-Content-Type-Options" = nosniff;
"X-Frame-Options" = SAMEORIGIN;
"X-Reader-Google-Version" = "527-000";
"X-Reader-User" = 01940378872835844713;
"X-Xss-Protection" = "1; mode=block";
}
response.statusCode = 400
So through alot of trial and error I've got it working.

If you are familiar with php I wrote a tutorial on using the google readi api recently.
http://mobile.tutsplus.com/tutorials/mobile-web-apps/building-a-mobile-web-application-with-the-google-reader-api/
One thing I notice is that in this string
http://www.google.com/reader/api/0/edit-tag/a=user/-/state/com.google/read&async=true&s=feed/%#&i=%#
Your not including the "edit" token the url should look like this. and you need the ? after edit-tag.
http://www.google.com/reader/api/0/edit-tag?a=user/-/state/com.google/read&async=true&s=feed/%#&i=%#&T=%#
You can get the "edit" token from this link once you have the user logged in, https://www.google.com/reader/api/0/token
Sorry can't help with objective-c stuff.
