This is my JSON response:
{"#error":false,
"#data":
{"personal_info":
{"basic_information":
{"EmailAddress":"k_bhuvaneswari#hcl.com",
"PasionProfessional":null,
"PasionPersonal":null,
"WorkLocation":"Chennai-AMB-6, Amb. Ind. Est., MTH Rd, 8",
"Country":null,
"City":null,
"Latitude":null,
"Longitude":null,
"Title":"Software Engineer",
"HomeTown":null,
"RelationshipStatus":null,
"BriefBio":null,
"FavouriteQuotation":null},
"education":
{"HighSchool":null,
"HighSchoolYear":null,
"HigherSecondary":null,
"HSSYear":null,
"DiplomaTechnical":null,
"DiplomaInsitute":null,
"YearofDiploma: ":null,
"Degree":null,
"YearofPassing":null,
"College/University":null,
"PostGraduation":null,
"YearofPostGraduation":null,
"PGCollege/University":null},
"interest":
{"Keywords":null},
"contact_information":
{"MobilePhone":"9791729428",
"BusinessCode":null,
"BusinessPhone":null,
"OtherCode":null,
"OtherPhone":null,
"Website":null}},
"work_profile_info":
{"profile_title":"",
"profile_bio":""},
"boolean":"1"}}
Now I want to display labels programmatically like this:
EmailAddress k_bhuvaneswari#hcl.com
PasionProfessional Nil
How can I do that?
Very easy. You need a JSON library that allows you to parse the data you recieve. I personally like JSONKit.
NSURL *url = [NSURL URLWithString:#"http://url.com"];
NSData *data = [NSData dataWithContentsOfURL:url];
NSDictionary *dict = [data objectFromJSONString]; //JSONKit
Then you can just step down the structure and grab the stuff you want:
NSString *email = [dict valueForKeyPath:#"#data.personal_info.basic_information. EmailAddress"];

I have an application in which I am having a json response like this.
{"success":"true","message":"You have logged in","pserial":"1"} and I am separating with ":".
And I am getting data like this pSerial:"1"} but I want only 1 value.
NSURL *url = [NSURL URLWithString:strUrl];
NSData *respData = [NSData dataWithContentsOfURL:url];
NSString *strResp = [[NSString alloc]initWithData:respData encoding:NSUTF8StringEncoding];
NSString *approvalString = [[strResp componentsSeparatedByString:#":"] objectAtIndex:3];
NSLog(#"pSerial:%#",approvalString);
for Example :
SBJsonParser *jsonPar = [[SBJsonParser alloc] init];
NSError *error = nil;
NSArray *jsonObj = [jsonPar objectWithString:jsonString error:&error];
id jsonObj = [jsonPar objectWithString:jsonString error:&error];
if ([jsonObj isKindOfClass:[NSDictionary class]])
// treat as a dictionary, or reassign to a dictionary ivar
else if ([jsonObj isKindOfClass:[NSArray class]])
// treat as an array or reassign to an array ivar.
Then get the value :
NSMutableArrary *userMutArr = [NSMutableArray array];
for (NSDictionary *dict in jsonObj)
{
User *userObj = [[[User alloc] init] autorelease];
[userObj setFirstName:[dict objectForKey:#"firstName"]];
[userObj setLastName:[dict objectForKey:#"lastName"]];
[userObj setAge:[[dict objectForKey:#"age"] intValue]];
[userObj setAddress:[dict objectForKey:#"address"]];
[userObj setPhoneNumbers:[dict objectForKey:#"phoneNumber"]];
[userMutArr addObject:userObj];
}
Hope you will understand. and read some Documents. it will help you.
It looks like you are in need of JSON Parsing. Here, what you want is JSON Parsing, not separating data from the JSON Response. JSON is the format of the data in which data is formatted in Key-Value pairs. You can fetch the "Value" of any object using the "Key".
Your first two lines are correct.
NSURL *url = [NSURL URLWithString:strUrl];
NSData *respData = [NSData dataWithContentsOfURL:url];
Now, you can parse JSON Response like this :
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:respData options:kNilOptions error:&error];
NSString *pSerial = [json objectForKey:#"pserial"];
This will give you the value of "pserial" from your response. Similarly, you can get the values for "success" and "message". You can check it using this line :
NSLog(#"pserial :: %#",pserial);
You need to parse the JSON Response String, you can use any JSON parser like:
https://github.com/stig/json-framework/
And in your code do:
NSString *strResp = [[NSString alloc]initWithData:respData encoding:NSUTF8StringEncoding];
NSDictionary *ResponseDictionary = [strResp JSONValue];
NSString * pSerial = (NSString*)[ResponseDictionary objectForKey:#"pserial"];
Dont separation by ":" just use JSONValue your response is like
// {"success":"true","message":"You have logged in","pserial":"1"}
// with SBJsonParser parse your object like this
NSDictionary *responseJson = [YOUR-OBJECT JSONValue];
Note: dont forget to add Json header file
Its better you use any OpenSource Json Parser
Here is a stack post Comparison of different Json Parser for iOS
I'm having problem with parsing json data file on iOS.
This is a sample from the data.json file:
var devs = [
{
"ident":"1",
"firstname":"Jan",
"lastname":"Kowalski",
"img":"http://www.placekitten.com/125/125",
"tech":"iOS, HTML5, CSS, RWD",
"github":"placeholder",
"opensource":"1",
"twitter":"placeholder"
},
{
"ident":"2",
"firstname":"WacĹaw",
"lastname":"GÄsior",
"img":"http://www.placekitten.com/124/125",
"tech":"Android, Java, Node.js",
"github":"GÄsiorBKR",
"twitter":"wacek5565"
},
and so on.
With "normal" json files I use:
NSURLResponse *response;
NSError *myError;
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://somerailsapplication/posts.json"] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30.0f];
NSData *data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&myError];
NSDictionary *res = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&myError];
Unfortunately this solution doesn't work in this case.
Is there any chance to get this working without searching for specific string "var dev=[" and the last "]" in the downloaded data?
The response is javascript, not JSON, so you won't be able to use a JSON parser directly. If you can't change the server output, the easiest thing would be to strip the beginning and end of the data, as you suggested. You could also embed the response in an HTML template and evaluate it in a webview, but that seems like a lot of more work.
Starting at the point where you've got the data:
NSData *data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&myError];
NSMutableString *dataAsString = [[NSMutableString alloc] initWithData:data encoding:NSUTF8StringEncoding];
[dataAsString deleteCharactersInRange:NSMakeRange(0, 11)];
data = [dataAsString dataUsingEncoding:NSUTF8StringEncoding];
NSArray *res = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&myError];
This turns the data into a string, removes the first 11 characters, turns it back into data, and then parses it as normal. (I've changed it to NSArray since your data is in an array)
I'm new in iPhone programming.
I have to parse this data in JSON in Objective-C.
{"success":1,"check":[{"ChkKey":"2","ChkDeb":"Connection 1","ChkSSID":"Netgear-1111","ChkIP":"192.168.2.103","ChkBlk":"0"}]}
I follow the example for parsing data with Json. But this JSON is so different.
It is composed by two Array.
How can i proceed?
Thanks - A.b.
How about trying something like this ...
//JSON string
NSString *jsonString = #"{\"success\":1,\"check\":[{\"ChkKey\":\"2\",\"ChkDeb\":\"Connection 1\",\"ChkSSID\":\"Netgear-1111\",\"ChkIP\":\"192.168.2.103\",\"ChkBlk\":\"0\"}]}";
//Parse JSON string into an NSDictionary
NSError *e = [[NSError alloc] init];
NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&e];
//Output the value of success
NSLog(#"Success:%#", [jsonData objectForKey:#"success"]);
//Get data in the check array
NSDictionary *checkData = [[jsonData objectForKey:#"check"] objectAtIndex:0];
//Output the value of ChkSSID
NSLog(#"ChkSSID:%#", [checkData objectForKey:#"ChkSSID"]);
I'm having a bit of trouble parsing some returned JSON. I'm fairly new to working with JSON. I'm trying to get the company name from the first JSON array element. I have a feeling that I'm confusing the use of NSMutabeArray and NSMutableDictionary. What I get is null. Any idea what I'm doing wrong?
NSString *url = #"http://www.google.com/finance/info?infotype=infoquoteall&q=C,JPM,AIG,AAPL";
NSData* data = [NSData dataWithContentsOfURL:
[NSURL URLWithString: url]];
//parse out the json data
NSError* error;
NSMutableArray* json = [NSJSONSerialization
JSONObjectWithData:data //1
options:kNilOptions
error:&error];
NSString* companyName = [[json objectAtIndex:0] objectForKey:#"name"] ; //Where I need some help
NSLog(#"we got %#", companyName);
Load that url in your browser. Looks like google is prefixing the JSON with //. I think NSJSONSerialization is tripping on that. Try this
NSRange range = NSMakeRange(2, [data length] - 3);
NSData *noPrefix = [data subdataWithRange:range];
Then send that to the parser.
You put in an error object, but you never looked at it. If you had, you would see that the data is corrupted:
Error Domain = NSCocoaErrorDomain Code = 3840 "The data couldn’t be read because it has been corrupted." (Invalid value around character 1.) UserInfo = 0x10030a8f0 { NSDebugDescription = Invalid value around character 1. }
I changed the value of the options parameter to see this error. I have
NSMutableArray* json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers |NSJSONReadingAllowFragments error:&error];
I have a servlet that serves up a plist XML file. What's the best way to slup this into an NSDictionary? I have this basically working with:
NSDictionary* dict = [ [ NSDictionary alloc] initWithContentsOfURL:
[NSURL URLWithString: #"http://example.com/blah"] ];
But then I have no control over the timeout; I'd rather not have my UI hang for 60 seconds just because the server (which I may not control) is having a hissy fit. I know about NSURLRequest, which will let me do the following:
NSURLRequest *theRequest=[NSURLRequest requestWithURL:
[NSURL URLWithString: #"http://example.com/blah"
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:5 ];
But I don't quite see how to feed that to NSDictionary.
You need to do this using the asynchronous methods. Start with this answer/post:
Can I make POST or GET requests from an iphone application?
This will get you your data and place it in a varibale: responseData. Now you need to add your code to convert it to a NSDictionary in the following method:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection;
I've found 2 possible ways to convert NSData to NSDictionary. This way is straight from the Apple Archives and Serializations Guide.
NSString *errorStr = nil;
NSPropertyListFormat format;
NSDictionary *dictionary = [NSPropertyListSerialization propertyListFromData: responseData
mutabilityOption: NSPropertyListImmutable
format: &format
errorDescription: &errorStr];
Second:
NSString *string = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];
NSDictionary *dictionary = [string propertyList];
[string release];
