using NSJSON
NSError *error;
NSData *jsonData = [decryptstr dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *returndict = [NSJSONSerialization JSONObjectWithData:jsonData
options:NSJSONReadingMutableContainers
error:&error];
returndict getting nil value.
add this line before convert ur string
NSString *decryptstr = [CTAES decrypt:text];
decryptstr = [NSString stringWithFormat:#"%s",[decryptstr UTF8String]];
Your string doesn't contain any escape characters, which Objective-C cann't read directly. So add escape characters to your string using following snippet.
// *** Get your string data ***
NSString *decryptstr = [CTAES decrypt:text];
// *** Add Escape characters to your string ***
NSString *escaped = [decryptstr stringByReplacingOccurrencesOfString:#"\"" withString:#"\\\""];
NSError *error;
// *** Convert escaped string to Data ***
NSData *jsonData = [escaped dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *returndict = [NSJSONSerialization JSONObjectWithData:jsonData
options:NSJSONReadingMutableContainers
error:&error];
NSLog(#"%#",returndict);
I just created one JSON file and copied your JSON data.
NSString *filePath = [[NSBundle mainBundle]pathForResource:#"data" ofType:#"json"];
NSData *data = [NSData dataWithContentsOfFile:filePath];
NSError *err;
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&err];

iOS fetching json object from json string
#"SaveRegistrationIDResult" : #"{\"Table\":[{\"Return_Code\":1,\"Return_Message\":\"ALREADY REGISTERED\"}]}"
I'm finding it impossible to fetch data from this json string.
I'm getting the table Table Object as a NSDictionary using this code.
NSMutableDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSData *processedJsondata = [jsonData objectForKey:#"SaveRegistrationIDResult"];
but I getting errors for everything i try ahead.
I'd like to fetch data from within the Table array ('Return_Code') and print it in a Log.
You are getting json string so you can parse it like,
id jsonString = #"{\"Table\":[{\"Return_Code\":1,\"Return_Message\":\"ALREADY REGISTERED\"}]}"; // or [yourDictionary objectForKey : #"SaveRegistrationIDResult"];
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
Now you can get value of any key from above object like,
NSArray *arr = [jsonObject objectForKey : #"Table"];
NSLog(#"your result : %#", arr);
Lion's comment worked. This is how I fetched the value. Any optimizations welcome. NSMutableDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error]; NSString *processedJsondata = [jsonData objectForKey:#"SaveRegistrationIDResult"]; NSData *tableData = [processedJsondata dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *tableJsonObject = [NSJSONSerialization JSONObjectWithData:tableData options:0 error:nil]; NSArray *tableArray = [tableJsonObject objectForKey:#"Table"]; NSDictionary *tableObject = [tableArray objectAtIndex:0]; NSString *reposnseCode = [tableObject objectForKey:#"Return_Message"]; NSLog(#"%#",reposnseCode);
Getting Web service response in string Format
I am using Afnetworking Framework in my project but I am getting the response in string format. I want to get the value of "Data" in the response below -
"{\"Result\":\"Success\",\"Data\":\"intro-1898-1449000428650.mp4\"}"
I have used the code below:
[Helper PostWebServiceRequest:kIntrovideo InputParameters:parameters competion:^(BOOL result, NSDictionary *response) {
if (result){
NSLog(#"response : %#",response);
NSString *data= [NSString stringWithFormat:#"%#",response ];
NSError *jsonError;
NSData *objectData = [data dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&jsonError];
since your response object seems to be an array and not (as stated) a dictionary, try the following: NSString *jsonString = ((NSArray *)response).firstObject; NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:nil]; NSString *data = jsonObject[#"Data"];
Not sure, but it seems that server can't pass object in Json, it's should pass link to place from where you can download this Data.
How to convert data string to json object and string in iOS?
How to convert string to JSON object or JSON array in iOS?
my JSON string Like That.
{"Data": [{"ID":"1","Name":"Raj"},{"ID":"2","Name":"Rajneesh"}]}
I want to get ID or Name from this string please help me if anyone now this.
Thank You.
I try below code but print null
NSString *JsonString=#"{"Data": [{"ID":"1","Name":"Raj"},{"ID":"2","Name":"Rajneesh"}]}";
NSData *objectData = [JsonString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:0 error:&error];
NSArray* array = [json objectForKey:#"Data"];
NSLog(#"Print Array %#",array);
Use this
NSString *str=#"{\"Data\": [{\"ID\":\"1\",\"Name\":\"Raj\"},{\"ID\":\"2\",\"Name\":\"Rajneesh\"}]}";
NSMutableDictionary *dict=[NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:nil];
NSMutableArray *dataArr=[dict valueForKey:#"Data"];
for (NSDictionary *userData in dataArr) {
NSLog(#"Id:%# Name:%#",[userData valueForKey:#"ID"],[userData valueForKey:#"Name"]);
}
Always Remember that when there are { } curly brackets, it means it is Dictionary and when [ ] this, means Array
NSURL *url=[NSURL URLWithString:#"Your JSON URL"];
NSData *data = [[NSData alloc] initWithContentsOfURL:url];
NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
NSArray *array = json[#"Data"];
for(NSMutableDictionary *dic in array)
{
NSLog(#"%#",dic[#"ID"]); // give 1 & 2
NSLog(#"%#",dic[#"Name"]); // Raj and Rajneesh
}
This is not the correct JSON string which can be parsed by Objective c, get string from encoder and you will get a valid string, other then that for JSON to Dictionary conversion is simple in iOS as its natively supported. NSData *data = [strJSON dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
Json to iOS Encoding Error
Problem: I can't parse data from a JSON file to a NSArray appropriately. UTF encoding is not working as expected.
My JSON looks something like:
[
{"Name":"Marcos","Address":"1234 Brasil Av. São Paulo - SP","Latitude":"-23.000","Longitude":"-46.70"},{"Name":"Mario","Address":"1000 Washignton Luiz Av. Itú SP","Latitude":"-20.0000","Longitude":"-46.000"}
]
My Objective-C code is:
NSError *error = nil;
NSURL *jsonUrl = [[NSURL alloc]initWithString:
#"http://marcosdegni.com.br/teste/webservice_teste.php"];
NSString *jsonString = [NSString stringWithContentsOfURL:jsonUrl
encoding:NSUTF8StringEncoding error:&error];
NSLog(#"jsonString: %# , Error:%#:" ,jsonString, error); //(1)
if (!error) {
NSError *error2 = nil;
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSArray * jsonArray = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error2];
NSLog(#"\n\nArray: %#" \nError:$#, jsonArray, error2); //(2)
//(*1*) This log show the content's as they are expected: note the characters ã and ú on the address fields.
//(*2*) The logs from the array and the dictionary show this charters as it's UNIX codes:\U00e and \U00fa respectively.
You can give this a try. The id json you get will be a NSArray, you can use it from there.
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSArray * array = json;
for (NSDictionary *dict in array) {
NSString *string = [dict objectForKey:#"Address"];
NSLog(#"%#",string);
}
From here, and I get the right result if I obtain the value of the key and log it, instead of logging the NSArray directly.
#"{\"details\": \"A friend request is already pending.\"}" how to retrieve the value from this json string
#"{\"details\": \"A friend request is already pending.\"}".. This is a json string coming from the server. i want to retrieve the object in a one string i.e is A friend request is already pending string is to be in one string. please tell me how to retrieve this.
i tried like this
NSString *str = #"{\"details\": \"A friend request is already pending.\"}";
NSLog(#"%#",str);
NSString *resultStr1 = [str stringByReplacingOccurrencesOfString:#"{" withString:#""];
NSString *resultStr2 = [resultStr1 stringByReplacingOccurrencesOfString:#"}" withString:#""];
//NSLog(#"%#",resultStr2);
//NSString *encodestr = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
// NSLog(#"%#",encodestr);
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
data = [data subdataWithRange:NSMakeRange(0, [data length] - 1)];
NSLog(#"%#",data);
NSError *error =Nil;
NSArray *JSON = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"%#",JSON);
NSLog(#"%#",[JSON valueForKey:#"details"]);
Try this. COnvert your string into a dictionary and access it by keys. This will be helpful when you come across large group of data.
NSString *str = #"{\"details\": \"A friend request is already pending.\"}";
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
NSError* error;
NSDictionary* dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
NSLog(#"%#", [dic objectForKey:#"details"]);
Try this may be it will help you NSDictionary *JSON = [NSJSONSerialization JSONObjectWithData: str dataUsingEncoding:NSUTF8StringEncoding] options: NSJSONReadingMutableContainers error: &e]; NSLog(#"%#",[JSON valueForKey:#"details"]);
