// NSMutableArray *array=[NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];
NSMutableArray *array = [jsonParser objectWithData:responseData];
NSLog(#"%#",array);
this array is null. i dont know the reason.
as i refer you request URL ,it has callback in it, if you keep it, it will not return you json as response, so remove "&callback=KISSY.Suggest.callback" from your URL
// Make sure you have include SBJSON files in your Project, as well you have imported header in your View Controller
#import "JSON.h"
// your request URL
NSURL * url = [NSURL URLWithString:#"http://suggest.taobao.com/sug?area=etao&code=utf-8&q=iphone"];
// URL Request
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSHTTPURLResponse* urlResponse = nil;
NSError * error = nil;
// initiate Request to get Data
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
// Encode your Response
NSString *content = [[NSString alloc] initWithBytes:[responseData bytes] length:[responseData length] encoding:NSUTF8StringEncoding];
// Now read a Dictionary from it using SBJSON Parser
NSDictionary *responseDict = [content JSONValue];
NSLog(#"Response [%#]",responseDict);
I'm not familiar with the SBJsonParser, but the format of the returned string looks like JSONP, not JSON. I would imagine simply cleaning out the wrapper call would get you what you are after.
Also, note that the 'root' of your response is a dictionary, not an array.
{"result": [[...
means that the code might should look like this:
NSDictionary *response = //... decode
NSArray *results = [response objectForKey:#"result"];
Edited
You just need to use http://suggest.taobao.com/sug?area=etao&code=utf-8&q=iphone instead of http://suggest.taobao.com/sug?area=etao&code=utf-8&callback=KISSY.Suggest.callback&q=iphone you own code will work..

Could you help me, with a example, where i consume a json webservice in a https url.
i have tried:
where urlConParametros is a https url.
NSString* encriptado = nil;
NSString* urlConParametros = [NSString stringWithFormat:#"%#%#?%#=%#", URL, metodo, key, valorSinEcncriptar];
NSError* error;
if(encriptado == nil){
NSMutableURLRequest *getRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlConParametros]];
[getRequest setHTTPMethod:#"GET"];
NSError *requestError;
NSURLResponse *urlResponse = nil;
NSData *response1 =[NSURLConnection sendSynchronousRequest:getRequest returningResponse:&urlResponse error:&requestError];
NSString* data = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlConParametros] encoding:NSUTF8StringEncoding
error:&error];
return data;
}
but return data nil.
My problem is that with http, the same web service response the correct data, but when it doing with https, the response is nil.
Please add some more details in the Question about What you want exactly, What you have tried and What are the Problems you are facing while implementation ?
If you want to GET some data from the Web Service , you can get it like this. :
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlConParametros]];
NSString *respStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"My Response :: %#",respStr);
If the Response is in JSON Format then you should do something like this :
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlConParametros]];
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"My Response :: %#",json);
Take a look at the Sample Code for AdvancedURLConnections.
I am new to iOS, so if any help it will be appreciated.
I am trying to get the longitude and latitude from address, earlier the code was working fine but now the JSON data are coming null.
Here my sample code,
url = [NSString stringWithFormat:#"http://maps.google.com/maps/api/geocode/json?address=%#&sensor=false",appDelegate.sAddress];
url=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"Address URL: %#",url);
//Formulate the string as a URL object.
NSURL *requestURL=[NSURL URLWithString:url];
NSData* data = [NSData dataWithContentsOfURL: requestURL];
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"my Coordinate : %#",returnString);
NSError* error;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:data
options:kNilOptions
error:&error];
But i am getting the output as null.
So please help me out.
Thanks!
Thanks for your replies that all make me learn a lots.
As one of my friend just tell me the solution so i am sharing with you.
Here is the code,
url = [NSString stringWithFormat:#"http://maps.google.com/maps/api/geocode/json?address=%#&sensor=false",appDelegate.sAddress];
url=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"Address URL: %#",url);
//Formulate the string as a URL object.
NSURL *requestURL=[NSURL URLWithString:url];
NSData* data = [NSData dataWithContentsOfURL: requestURL];
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
SBJSON *parser = [[SBJSON alloc] init];
NSDictionary *locationResult = [parser objectWithString:returnString];
//[reverseGeoString copy]`
And its working fine.
But still there is a question that why this happen.As earlier that code is working fine but it suddenly stopped working.
You must construct your returnString in the following method that actually receives the data:
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
Check out this for additional information on how to use NSURLConnection and the delegate methods.
I would say you're missing the all-important "REQUEST"...
This is what I do. Hope it helps:
NSString *encodedAddress = (__bridge_transfer NSString *) CFURLCreateStringByAddingPercentEscapes(NULL, (__bridge_retained CFStringRef)searchBar.text, NULL, (CFStringRef) #"!*'();:#&=+$,/?%#[]",kCFStringEncodingUTF8 );
NSString* searchURL = [NSString stringWithFormat:#"http://maps.googleapis.com/maps/api/geocode/json?address=%#&sensor=true",encodedAddress];
NSError* error = nil;
NSURLResponse* response = nil;
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] init];
NSURL* URL = [NSURL URLWithString:searchURL];
[request setURL:URL];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setTimeoutInterval:30];
NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if (error){
NSLog(#"Error performing request %#", searchURL);
return;
}
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
if (jsonString!=nil){
NSLog(#"%#",jsonString);
}
I send some credentials to a web-service.
I can get the responce as NSData or as an NSString.
Whats the simpleist way to convert the (NSData or NSString)JSON to a NSDictionary so I can process it?
Building for iOS4.3
Many Thanks,

From iOS 5.0 and on you can use NSJSONSerialization, docs here.
There is a good tutorial on how to use it, here.
Download SBJsonParser Framework using the link, http://github.com/stig/json-framework/downloads and add required classes to your project (SBJsonParser.h).
Import SBJsonParser.h and use the following code,
SBJsonParser *parser = [[SBJsonParser alloc] init];
//dictionary with name,id
NSDictionary *jsonObject = [parser objectWithString:jsonString error:NULL];
//name array
NSMutableArray *nameArray = [[NSMutableArray alloc]init];
for (NSMutableDictionary *dic in jsonObject){
[nameArray addObject:[dic valueForKey:#"name"]];
}
Use this :
NSString *urlString = [NSString stringWithFormat:kURLString,self.chapter,self.page];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:[urlString dataUsingEncoding:NSISOLatin1StringEncoding]];
NSData* responseData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:nil error:nil];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSISOLatin1StringEncoding];
NSDictionary* result = [(NSDictionary*)[responseString JSONValue] objectForKey:#"Result"];
I use SBJson
NSArray *arrObj = (NSArray*)[[JsonParser sharedJsonParser] getObjectsFromJsonString:responseString];
response string is a JSON string here
Hi I would like to know how I can go about sending data from 4 UITextField's to a PHP script on a website using NSURLConnection or JSon. Whatever is easier, how can I do this exactly?
Thanks in advance!
Easiest way (synchronous)
NSString strForTextField1 = textField1.text;
NSString strForTextField2 = textField1.text;
NSString strForTextField3 = textField1.text;
NSString strForTextField4 = textField1.text;
//Build the request
NSString *stringOfRequest = [NSString stringWithFormat:#"www.yourserver.com?var1=%#&var2=%#&var3=%#&var4=%#", strForTextField1, strForTextField2, strForTextField3, strForTextField4];
NSURL *url = [NSURL URLWithString:stringOfRequest];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLResponse *response;
NSError *error;
//send it synchronous
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
if(!error)
{
//log response
NSLog(#"Response from server = %#", responseString);
}
Below is my code..
NSString *strResponce = [[NSString alloc] initWithData:JsonData encoding:NSASCIIStringEncoding];
here string has some data.
[JsonData release];
NSError *error;
SBJSON *json = [[SBJSON new] autorelease];
ArrayWebContent=[json objectWithString:strResponce error:&error];
But array is null.
any suggestion....
check your json data first put the content of the string strResponce in to the url
Checking json data are proper for parsing
if it gonna generate the parse error than you should check the content of the ws as it may content special charactor for which iphone can not support parsing
good luck
Try with below functions.
- (id) objectWithUrl:(NSURL *)url
{
SBJSON *jsonParser = [SBJSON new];
NSString *jsonString = [self stringWithUrl:url];
// Parse the JSON into an Object
return [jsonParser objectWithString:jsonString error:NULL];
}
- (NSString *)stringWithUrl:(NSURL *)url
{
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad
timeoutInterval:30];
// Fetch the JSON response
NSData *urlData;
NSURLResponse *response;
NSError *error;
// Make synchronous request
urlData = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:&response
error:&error];
// Construct a String around the Data from the response
return [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding];
}
Let me know for any difficulty.
