how to print the key event_id on label.
"all_data" = (
{
"company_logo" = "http://mbdbtechnology.com/projects/officeapp/uploads/event/Voxev\U00e6rket_logo_stort.png";
"event_id" = 8;
"event_name" = "Dit nye kontor i Voxev\U00e6rket";
"event_sort_desc" = "Voxev\U00e6rket tilbyder landsd\U00e6kkende kontorer til ny opstartede";
},
{
"company_logo" = "http://mbdbtechnology.com/projects/officeapp/uploads/event/Image_jpg_2_288X200.jpg";
"event_id" = 7;
"event_name" = "Sunday Special only for women";
"event_sort_desc" = "Declarations of war At midnight on 31 July \U2013 1 Aug, French 2";
},
try this:
NSMutableDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
//responseData is an NSData object containing the jSON
NSMutableArray *allData = [jsonDict objectForKey:#"all_data"];
for (NSDictionary* dict in allData)
{
NSString *eventID = [dict objectForKey:#"event_id"];
NSLog(#"event ID : %#",eventID);

i'm working on one objective C application where i'm taking JSON data and i need to insert this data(date) inside Dictionary fillDefaultColors. My fillDefaultColors should be in format like this:
self.fillDefaultColors = #{ #"2017/06/18":greenColor,
#"2017/06/19":orangeColor,
#"2017/06/20":greenColor,
...
};
but when i print in console log they are each in separate row and in application i can see colour just for last item from JSON
2017-06-19 15:30:12.310 CalendarTest[1905:364525] {
"2017/06/20" = "greenColor";
}
2017-06-19 15:30:12.311 CalendarTest[1905:364525] {
"2017/06/18" = "orangeColor";
}
So in application i see background for last date in console 2017/06/18
Here is my code
NSError *error = nil;
NSURL *url = [NSURL URLWithString: #"http://..."];
NSData *data = [NSData dataWithContentsOfURL:url options:NSDataReadingUncached error:&error];
if(!error)
{
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:data
options:NSJSONReadingMutableContainers
error:&error];
NSMutableArray *array= [json objectForKey:#"horses"];
for(int i=0; i< array.count; i++)
{
NSDictionary *horsedata = [array objectAtIndex:i];
NSString *date = [horsedata objectForKey:#"date"];
NSNumber *averagetemp = [horsedata objectForKey:#"averagetemperature"];
if([averagetemp isEqual:#(28)]) {tempColor = greenColor;} else {
tempColor = orangeColor;
}
self.fillDefaultColors = #{date: tempColor};
NSLog(#"%#", _fillDefaultColors);
}
}
JSON: {"horses":[{"id":1,"name":"Horse","date":"2017/06/17","averagetemperature":28},{"id":1,"name":"Horse","date":"2017/06/18","averagetemperature":25}]}
Thanks
it s because you are allocating a new dictionary in each iteration:
self.fillDefaultColors = #{date: tempColor};
you need to append instead:
NSMutableArray *array= [json objectForKey:#"horses"];
self.fillDefaultColors = [[NSMutableDictionary alloc]init];
for(int i=0; i< array.count; i++)
{
NSDictionary *horsedata = [array objectAtIndex:i];
NSString *date = [horsedata objectForKey:#"date"];
NSNumber *averagetemp = [horsedata objectForKey:#"averagetemperature"];
if([averagetemp isEqual:#(28)]) {tempColor = greenColor;} else {
tempColor = orangeColor;
}
[self.fillDefaultColors setObject:tempColor forKey:date];
NSLog(#"%#", _fillDefaultColors);
}
This is the same solution as in Hussein's answer but with Modern Objective-C Syntax – which has been introduced at least 5 years ago.
NSArray *horses = json[#"horses"];
self.fillDefaultColors = [[NSMutableDictionary alloc] init];
for (NSDictionary *horsedata in horses)
{
NSString *date = horsedata[#"date"];
NSNumber *averagetemp = horsedata[#"averagetemperature"];
self.fillDefaultColors[date] = (averagetemp.integerValue == 28) ? greenColor : orangeColor;
NSLog(#"%#", _fillDefaultColors);
}
I want to send NSDictionary data with AFNetworking POST method and get result from server.
this my NSDictionary :
{
"category_id" = "-1";
"city_id" = "-1";
"degree_id" = "-1";
"experience_id" = "-1";
industries = (
{
id = 2;
},
{
id = 4;
},
{
id = 3;
}
);
"position_id" = "-1";
"salary_id" = "-1";
skills = (
{
aa = id;
},
{
aa = asdasda;
}
);
"type_id" = "-1";
}
when send this NSDictionary my server receive my data like this :
{
"category_id" = "-1";
"city_id" = "-1";
"degree_id" = "-1";
"experience_id" = "-1";
industries = (
2,
4,
3
);
"position_id" = "-1";
"salary_id" = "-1";
skills = (
id,
asdasda
);
"type_id" = "-1";
}
I'm so confused from this !!!
industries & skills are array of dictionary in my NSDictionary but when server to receive don't show key and only show value in array!!!
please guide me about that.
this is my POST method :
self.params = [[NSMutableDictionary alloc]init];
[self.params setObject:[NSNumber numberWithInteger:[self.object.jobCategory integerValue]] forKey:#"category_id"];
[self.params setObject:[NSNumber numberWithInteger:[self.object.jobCity integerValue]] forKey:#"city_id"];
[self.params setObject:self.object.industry forKey:#"industries"];
[self.params setObject:[NSNumber numberWithInteger:[self.object.educationDegree integerValue]] forKey:#"degree_id"];
[self.params setObject:[NSNumber numberWithInteger:[self.object.experience integerValue]] forKey:#"experience_id"];
[self.params setObject:[NSNumber numberWithInteger:[self.object.jobType integerValue]] forKey:#"type_id"];
[self.params setObject:[NSNumber numberWithInteger:[self.object.jobSalary integerValue]] forKey:#"salary_id"];
[self.params setObject:[NSNumber numberWithInteger:[self.object.jobPosition integerValue]] forKey:#"position_id"];
[self.params setObject:[NSMutableArray array] forKey:#"skills"];
[[self.params objectForKey:#"skills"] addObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:#"id",#"aa", nil]];
[[self.params objectForKey:#"skills"] addObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:#"asdasda",#"aa", nil]];
//NSData *jsonData = [NSJSONSerialization dataWithJSONObject:self.params options:NSJSONWritingPrettyPrinted error:nil];
//NSString *str = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(#"%#",self.params);
NSString* path = [NSString stringWithFormat:#"%#%#" , [PublicMethods getStrings:#"url"],[PublicMethods getStrings:#"searchJob"]];
[self.network callPOSTWebServiceWithPath:path AndWithParameters:self.params withCallback:^(NSDictionary *result)
{
NSLog(#"%#",result);
if ([[result objectForKey:#"result"]boolValue])
{
NSLog(#"%#",[result objectForKey:#"data"]);
}
else
{
//error accured
}
}];
It is a very easy issue.
You send a string data in which includes NSDictionary nested NSArray.
But you send it to the server.
Your code of industries and skills which there is the same key in the array.
So when it sent to the server, and then returned value without key.That's correct.
Wanna see your returned value with key.Just change your id likes id1, id2, id3. As to it ,the variable of aa is just like that.
Finally , you'll see the key with value be returned .
Good luck！
Apologies if this is a novice question, but I've been struggling to figure this out with no luck. I'm trying to pull a users' twitter timeline using the AFOAuth2Manager framework. Everything makes sense except the returned JSON object is an array and the entire object is one giant object. I obviously want to break it up into different elements and store them in a dictionary, but have not been able to figure it out so far.
This is a VERY partial example of what the array object looks like. The complete object is this with about 20 or so more tweets with this format attached. I will post the entire json object if requested, but it seems pretty pointless to post the entire thing.
Heres my code:
[manager GET:#"/1.1/statuses/user_timeline.json?screen_name=jack"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject ) {
self.object = responseObject;
NSLog(#"Success: %#", responseObject);
if ([responseObject isKindOfClass:[NSArray class]]) {
NSLog(#"object is a nsarray class");
} else if ([responseObject isKindOfClass:[NSDictionary class]]){
NSLog(#"object is a nsdictionary class");
} else {
NSLog(#"object is a different class");
}
NSArray *response = [NSArray arrayWithObject:responseObject];
NSLog(#"count %ld", [response count]);
NSData *dataFromTwitter = [NSKeyedArchiver archivedDataWithRootObject:self.object];
NSError *parseError = nil;
NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:dataFromTwitter
options:NSJSONReadingMutableLeaves | NSJSONReadingMutableContainers|NSJSONReadingAllowFragments
error:&parseError];
NSLog(#"response Dict: %#", responseDict);
NSError *e = nil;
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:dataFromTwitter
options:NSJSONReadingAllowFragments
error:&e];
NSLog(#"jsonArray: %#", jsonArray);
NSError *jsonError2 = nil;
id jsonObject = [NSJSONSerialization JSONObjectWithData:dataFromTwitter
options:NSJSONReadingAllowFragments
error:&jsonError2];
if ([jsonObject isKindOfClass:[NSArray class]]) {
NSLog(#"its an array!");
NSArray *jsonArray = (NSArray *)jsonObject;
NSLog(#"jsonArray2 - %#",jsonArray);
}
else {
NSLog(#"its probably a dictionary");
NSDictionary *jsonDictionary = (NSDictionary *)jsonObject;
NSLog(#"jsonDictionary - %#",jsonDictionary);
NSLog(#"error %#", jsonError2);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", error);
}];

You show no code in your question, in a comment you state you have a responseObject but not how you came by it.
The JSON you are getting from somewhere will be text, you may have it as an NSString, NSData, an NSArray whose elements are these, etc.
You need to obtain that text and then parse it as JSON, the NSJSONSerialization class will handle the parsing for you, the first line of its description states:
You use the NSJSONSerialization class to convert JSON to Foundation objects and convert Foundation objects to JSON.
Once you have those Foundation objects - arrays, dictionaries, strings, numbers, etc. you can extract the fields you are interested in.
Once you've written some code to do this if it doesn't work and you are stuck ask a new question showing your code and someone will probably be able to help you further.

I begin in Ios dev and I got some troubles to manipulate an array create by Json :
I call in my app a web Service which return me data :
{evenements =(
({
dateEvenement ={
1 = "01-01-2013";
2 = "02-01-2013";
3 = "03-01-2013";
4 = "04-01-2013";
};
idEvenement = 61;
nbrInvite = 1;
nomEvenement = "My event Name";
nomUtilisateur = "Lucas ";
}
),
);
}
I'm able to get all the values by the following code except for "dateEvenement" :
NSArray *msgList;
msgList = [ jsonResults objectForKey:#"evenements" ];
for (NSDictionary *evenements in msgList) {
for (NSDictionary *evenement in evenements ) {
NSString *idEvenement = [evenement objectForKey:#"idEvenement"];
NSString *nomUtilisateur = [evenement objectForKey:#"nomUtilisateur"];
NSString *nomEvenement = [evenement objectForKey:#"nomEvenement"];
NSString *nbrInvite = [evenement objectForKey:#"nbrInvite"];
NSArray *dates = [ evenement objectForKey:#"dateEvenement" ];
}
}
Can you help me for getting datas of "dateEvenement"
Well in your JSON the dateEvenement isn't an Array but a dictionary:
NSDictionary *dates = [ evenement objectForKey:#"dateEvenement"];
for(NSNumber *key in dates) {
NSString *dateString = [dates objectForKey:key];
NSLog(%# : %#, key, dateString);
}
As declared in your JSON example the key's for the dictionary are numbers, thus you should NSNumber object for the key type.
{
"id": "1",
"result": [
{
"Name": "John",
"Statu": "Online"
},
{
"Name": "Alex",
"Statu": "Online"
},
{
"Name": "Diaz",
"Statu": "Offline"
}
]
}
How do i extract each "car" JSON object and put it into a native object? I tried several way but i can't do that.
NSString *responseString = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
NSString *responseDict = [responseString JSONValue];
NSArray *objects = [NSArray arrayWithObjects:[responseDict valueForKeyPath:#"result.Name"],[responseDict valueForKeyPath:#"result.Statu"],nil];
NSLog(#"objects Array: %#",objects);
**==> NSLOG gives:
(
(
"John",
"Alex",
"Diaz"
),
(
"Online",
"Online",
"Offline"
)
)
NSArray *resultsArray = [responseString JSONValue];
for (NSDictionary *personDict in resultsArray)
{
NSLog(#"ihaleAdi =: %#",[carDict valueForKey:#"result.ihaleAdi"]);
NSLog(#"ihaleDurum =: %#",[carDict valueForKey:#"result.Statu"]);
}
But ıt gıves an error tooç I want to just lıst them but ı cant do thatç can anybody help me please? thank you for reading
Use an Array to capture the responseString:
NSString *responseString = [request responseString];
NSArray *array = [responseString JSONValue];
Then when you need an individual item from that array use a Dictionary:
// 0 is the index of the array you need
NSDictionary *itemDictionary = (NSDictionary *)[array objectAtIndex:0];
Given a JSON responseString that looks like this:
[{"UniqueID":111111,"DeviceName":"DeviceName1","Location":"Device1Loc","Description":"Device1Desc"},{"UniqueID":22222,"DeviceName":"DeviceName2","Location":"Device2Loc","Description":"Device2Desc"}]
You will wind up with an Array that looks like this:
myArray = (
{
Description = "Device1Desc";
DeviceName = "DeviceName1";
Location = "Device1Loc";
UniqueID = 111111;
},
{
Description = "Device2Desc";
DeviceName = "DeviceName2";
Location = "Device2Loc";
UniqueID = 222222;
}
)
And a Dictionary of index 0 that looks like this:
myDictionary = {
Description = "Device1Desc";
DeviceName = "DeviceName1";
Location = "Device1Loc";
UniqueID = 111111;
}
Sorry for any confusion and improperly instantiated object earlier. I am still a relative newbie that learned something today.
