I made NSData from GET request.
NSString *nameID = [[NSString alloc]initWithString: #"1"];
NSString *urlString = [NSString stringWithFormat:#"http://www.xxxxx.com/news/index.php?id=%#",
[nameID stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSURL *url = [[NSURL alloc] initWithString:urlString];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSData *urlData;
NSURLResponse *response;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];
NSString *results = [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(#"%#",urlData);
And then how to parse that? I've got only something like:
2011-10-21 19:27:06.213 httptest[1674:207] <3c21444f 43545950 45206874 6d6c2050 55424c49 4320222d 2f2f5733 432f2f44 54442058 48544d4c
You are logging urlData (an NSData object) instead of results (the NSString). NSData objects are displayed in the output console as hex digit pairs. If you log 'results' you will see something like:
<!DOCTYPE http...
which is probably what you were expecting.
you have already converted the resulting data to a NSString
at first you have to define what that data is: XML- or JSON-String? or Binary-encoded stuff? and then you have to write your own parser or choose one you like.
I assume that your result is xml and lets just assume that you want to use the TBXML-Dom-Parser. then try:
NSString *results = [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding];
TBXML * tbxml = [TBXML tbxmlWithXmlString:result];
TBXMLElement *rootElement = tbxml.rootElement;
TBXMLElement *childELement = [TBXML childElementNamed:#"myChildTag" parentElement:rootElement]
..... //depends on how your xml looks like

// 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..
I have received string from webservice which contains Unicode character. I want to convert that To plain NSString. so How can i do that?
ex: "This isn\u0092t your bike"
So how can remove unicode and replace it with its equal special symbol characted.
The output would be : "This isn't your bike"
char cString[] = "This isn\u2019t your bike";
NSData *data = [NSData dataWithBytes:cString length:strlen(cString)];
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"result string: %#", string);
This should work.
UPDATE FOR THE COMMENT:
The unicode character specified by you is not supported in all fonts.
http://www.fileformat.info/info/unicode/char/92/fontsupport.htm
But this one does.
http://www.fileformat.info/info/unicode/char/2019/fontsupport.htm
Thats why it throws an error.
NSString *final_url = [NSString stringWithFormat:url];
final_url = [final_url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:final_url] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:120.0];
NSURLResponse *response;
NSError *error = [[NSError alloc] init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *strResponse = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
SBJSON *objJSON = [SBJSON new];
NSMutableDictionary *objDataDic = [objJSON objectWithString:strResponse error:nil];
There is a library which does conversion
https://github.com/alexaubry/HTMLString. It will convert all kind of Unicode character.

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);
}
when I run the following google translation API URL http://translate.google.com/translate_a/t?client=t&text=Hello&langpair=en|fr it returns the correct result.
However, when I try to use the following in Xcode it returns (Null). I would appreciate any help or insight you can provide.
NSString *urlPath = [NSString stringWithFormat:#"/translate_a/t?client=t&text=%#&langpair=en|fr",#"Hello"];
NSURL *url = [[NSURL alloc] initWithScheme:#"http" host:#"translate.google.com" path:urlPath];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:#"GET"];
NSURLResponse *response;
NSError *error;
NSData *data;
data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *result = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Text: %#",result);
Your encoding is incorrect. change it to NSASCIIStringEncoding.
I just fixed your code and ran it locally and it worked like a charm...
here are the results
[[["Bonjour","Hello","",""]],[["interjection",["bonjour","salut","all\u00f4","tiens"]]],"en",,[["Bonjour",[5],1,0,1000,0,1,0]],[["Hello",4,,,""],["Hello",5,[["Bonjour",1000,1,0]],[[0,5]],"Hello"]],,,[],1]
I am trying to parse some JSON. I've passed a constant key value and a string - butI'm receivng 16 objects in the statuses array and 20 objects in ststuses1.
Are any of the parsing steps wrong?
I have included the code for the JSON parser.
Thanks in advance.
SBJSON *parser = [[SBJSON alloc] init];
NSString *urlString =[NSString stringWithFormat:#"http://api.shiki.com/api/serch?key=%#&q=%#",apiKey, string];
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSMutableArray *statuses = nil;
statuses = [[NSMutableArray alloc]init];
statuses = [parser objectWithString:json_string error:nil];
NSMutableArray *statuses0 = [[statuses valueForKey:#"offers"] valueForKey:#"offer"];
NSLog(#"Array Contents: %#", statuses0);
I guess that's not the only syntax-error in your code...
Please define statuses and ststuses1. I can only see statuses (redefined 2 times) and statuses0. Also please post a sample of the json-data you're parsing so I can take a look at it.
