I need to add multiple NSDictionaries into an NSArray to get a JSON message.I want to get this string.
This is my code:
for (int i=0;i<[ids count]; i++)
{
[dict setObject:[NSString stringWithFormat:#"%#",personName] forKey:#"customerName"];
NSArray *array = [NSArray arrayWithObject:cartDict];
[dict setObject:array forKey:#"OrderDetails"];
}
NSString *request1 = [dict JSONRepresentation];
//convert object to data
NSData *jsonData = [NSData dataWithBytes:[request1 UTF8String] length:[request1 length]];
//NSData* jsonData = [NSJSONSerialization dataWithJSONObject:req options:NSJSONWritingPrettyPrinted error:nil];
//print out the data contents
json1 = [[NSString alloc] initWithData:jsonData
encoding:NSUTF8StringEncoding];
You are just changing the values in the same instance of the cartDict. If you want to have more than one cartDict in your array, alloc and init a new NSDictionary and then add that to the array (don't forget to release after if you aren't using ARC!).

I get a returnString from a WebService in iOS:

]
the Objective C Code works fine:
#import "SBJson.h"
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
self.textfeld.text = [NSString stringWithFormat: #"%#", returnString];
I try to format the Response with NSMutableArray or NSArray and JSONValue but without success :
NSMutableArray *meinErgebnis = [responseString JSONValue];
NSLog(#"%#",[[meinErgebnis objectAtIndex:0] objectAtIndex:1]);
How to format the returnCode like that?
Nummer: 1017348010239480212208
Anmerkung: Sendung in Verteilung
Nummer: 1017348010239480212208
Anmerkung: Sendung in Post-Empfangsbox
You can obtain Data with following method,
id Data = [NSJSONSerialization JSONObjectWithData:fetchedData options:kNilOptions error:&error];
Then you can loop the data accordingly. For your example,
for(id object in Data)
{
NSLog(#"%#",[object valueForKey:#"nummer"]);
NSLog(#"%#",[object valueForKey:#"anmerkung"]);
}
The loop used above is of fast Enumeration type. Hope this helps.
Use following code for get all the values of nummer and anmerkung from your mutable array.
NSMutableArray *meinErgebnis = [responseString JSONValue];
for(int i = 0; i < meinErgebnis.count; i++)
{
NSLog(#"%#",[[meinErgebnis objectAtIndex:i] objectForKey:#"nummer"]);
NSLog(#"%#",[[meinErgebnis objectAtIndex:i] objectForKey:#"anmerkung"]);
}
I have a String that I got from a webserver which came in json format, but the string is huge with everything in it. I tried using the NSDICTIONARY but to no success. I was wondering what would be the best approach to break this string and add to different strings and eventually put it all in a class of strings. Thanks for the help! Here is my code:
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setURL:[NSURL URLWithString:#"http://mym2webdesign.com/meiplay/paulsuckedabuffalo/artists.php"]];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; //Or async request
returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSError *error=nil;
NSLog(#"HHHHHHHHHHHHHH"); //use this to know how far Im getting
NSLog(returnString); // Look at the console and you can see what the restults are
/*NSDictionary *results = [returnString JSONValue];
NSString *ID = [results objectForKey:#"ID"]; // for example
NSLog(#"ID Number: %#", ID);*/
Here is some of the log i get:
[{"ID":"1","name":"kevin","bio":"kevins bio"},{"ID":"1","name":"kevin","age":"20"},{"ID":"2","name":"Cesar","bio":"Cesar bio"},{"ID":"2","name":"Cesar","age":"19"},{"ID":"3", "name":"Katherine", "bio":"Katherines bio"},{"ID":"3", "name":"Katherine", "age":"22"}]
You are doing it wrong. Its a NSArray of NSDictionaries. So first you need to assign it to NSArray and then loop over it to get each individual NSDictionary. See below.
NSArray *results = [returnString JSONValue];
for(NSDictionary *record in results)
{
NSLog(#"ID: %#", [record objectForKey:#"ID"]);
}
You'll probably be better off just using NSJSONSerialization if your app is targeted for at or over iOS 5.0:
NSArray *JSONArray = [NSJSONSerialization JSONObjectWithData:returnData options:0 error:&error];
You might need to experiment with using NSArray vs. NSDictionary, etc., but this should be an overall simpler solution.
Try this :
NSArray *results = [returnString JSONValue];
for (int i=0; i<[results count];i++) {
NSDictionary *DetailDictonary=[results objectAtIndex:i];
NSString *strid=[DetailDictonary objectForKey:#"ID"];
NSString *strName=[DetailDictonary objectForKey:#"name"];
NSString *strBio=[DetailDictonary objectForKey:#"bio"];
// Or You can set it in Your ClassFile
MyClass *classObj=[[MyClass alloc] init];
classObj.strid=[DetailDictonary objectForKey:#"ID"];
classObj.strName=[DetailDictonary objectForKey:#"name"];
classObj.strBio=[DetailDictonary objectForKey:#"bio"];
[YourMainArray addObject:classObj]; //set YourClass to Array
[classObj release];
}
My code:
NSString *jsonString;
jsonString = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
// Create a dictionary from the JSON string
NSDictionary *results = [jsonString JSONValue];
NSLog(#"%#",jsonString);
// Build an array from the dictionary for easy access to each entry
NSArray *places = [results objectForKey:#"description"];
I am not getting the result i wanted.
When I debug the code I am getting 2 key/value pair & 0 object for NSArray places.
It is correct that you have 2 key/value pairs. The top two keys intact are "predictions" and "status". So you must first of all extract predictions (it's an array):
NSArray *predictions = [results objectForKey:#"predictions"];
and then iterate over it; also note that "description" is a string and to get the places you must split it using the "," separator:
for(NSDictionary *aPrediction in predictions) {
NSString *description = [aPrediction objectForKey:#"description"];
NSArray *placesInDescription = [description componentsSeparatedByString:#","];
}
maybe you should use:
NSArray *places = [results valueForKey:#"predictions"];
Works for me without any problems with JSON Kit!
NSString *jsonString;
NSData *responseData = [NSData dataWithContentsOfURL: [NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/autocomplete/json?input=solapur&sensor=true&key=AIzaSyC0K5UhV_BWmXhncIZEnbh-WG2RVQVgfdY"]];
jsonString = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
// Create a dictionary from the JSON string
NSDictionary *results = [jsonString objectFromJSONString];
// Build an array from the dictionary for easy access to each entry
NSArray *places = [results valueForKey:#"predictions"];
NSLog(#"places %#", places);
i have the following json value in console:
{"TokenID":"kuiHigen21","isError":false,"ErrorMessage":"","Result":[{"UserId":"153","FirstName":"Rocky","LastName":"Yadav","Email":"rocky#itg.com","ProfileImage":null,"ThumbnailImage":null,"DeviceInfoId":"12"}],"ErrorCode":900}
this is my server api :#"http://192.168.0.68:91/JourneyMapperAPI?RequestType=Login"
//api takes 5 parameters .
when i post data to server api values are posted to server and i get the above response in json format.
i want to parse the above the JSON value that i get in the response and save in sqlite database.
i am doing this code to parse the above JSON value:
-(void)connectionDidFinishLoadingNSURLConnection *)connection
{
NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] lengthwebData length] encoding:NSUTF8StringEncoding];
NSLog(#"%#",loginStatus);
self.webData = nil;
SBJSON *parser =[[SBJSON alloc]init];
NSURLRequest *request = [NSURLRequest requestWithURLNSURL URLWithString"http://192.168.0.68:91/JourneyMapperAPI?RequestType=Login.json"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
// Get JSON as a NSString from NSData response
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
//NSDictionary *object = [parser objectWithString:json_string error:nil];
// parse the JSON response into an object
// Here we're using NSArray since we're parsing an array of JSON status objects
NSArray *statuses = [parser objectWithString:json_string error:nil];
for (NSDictionary *status in statuses)
{
// You can retrieve individual values using objectForKey on the status NSDictionary
// This will print the tweet and username to the console
NSLog(#"%# - %#", [status objectForKey"Login"],[status objectForKey"LoginKey"]);
[connection release]; [webData release];
}
You should check out some of the JSON parsers, my personal favourite is json-framework. After you've included one of them in your project, where you've got your JSON response from your server:
// Get JSON as a NSString from NSData response
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *result = [json_string JSONValue];
NSArray *statuses = [result objectForKey:#"Result"];
which will return your array of results (where each object in the array is an NSDictionary).
You can save this to a database with the help of a model class, Result
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *result = [json_string JSONValue];
NSArray *values = [result objectForKey:#"Result"];
NSMutableArray *results = [[NSMutableArray alloc] init];
for (int index = 0; index<[values count]; index++) {
NSMutableDictionary * value = [values objectAtIndex:index];
Result * result = [[Result alloc] init];
result.UserId = [value objectForKey:#"UserId"];
result. FirstName = [value objectForKey:#"FirstName"];
...
[results addObject:result];
[result release];
}
use the array of results to save it to the database.
for (int index = 0; index<[results count]; index++) {
Result * result = [results objectAtIndex:index];
//save the object variables to database here
}
How to convert NSArray into NSString in objective-c?
Bearing in mind that you don't say what's in the NSArray, you can do this:
NSArray *arr = [NSArray arrayWithObjects: #"foo", #"bar", #"baz"];
[arr componentsJoinedByString: #","]
Aternatively to Frank's method, which works pretty well, you could also do
NSString *myArrayString = [array description];
The default implementation of description on NSArray will print out the contents in a neatly formatted fashion.
This is how I have converted my NSArray to NSString
NSError *error = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:aArray options:kNilOptions error:&error];
NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
Swift 3.0 latest updates
let string = array.componentsJoined(by: ",")
you can used any separator in function which you want to separate the array elements currently in above example is ",".
