Im fetching JSON data from this link.
http://www.krsconnect.no/community/api.html?method=event&appid=620&eventid=15946&affecteddate=1310515200000
I want to store all the required elemnts like image-medium title etc in aDetail object of Detail class but its giving error.
Here is my code:
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.krsconnect.no/community/api.html?method=event&appid=620&eventid=15946&affecteddate=1310515200000"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *object = [parser objectWithString:json_string error:nil];
NSArray *results = [parser objectWithString:json_string error:nil];
for (int i=0; i<[results count]; i++) {
NSDictionary*dictOne=[results objectAtIndex:i];
Detail *aDetail = [[Detail alloc] initWithDictionary:[results objectAtIndex:i]];
[appDelegate.descriptionArray addObject:aDetail];
}
that's not how you use SBJSon. Try this:
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.krsconnect.no/community/api.html?method=event&appid=620&eventid=15946&affecteddate=1310515200000"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *object = [json_string JSONValue];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSError *error;
SBJSON *json = [[SBJSON new] autorelease];
id obj = [json objectWithString:json_string error:&error];
if ([obj isKindOfClass:[NSDictionary class]]) {
[appDelegate.descriptionArray addObject:obj];
}else if ([obj isKindOfClass:[NSArray class]]) {
for (NSDictionary *aDetail in obj) {
[appDelegate.descriptionArray addObject:aDetail];
}
}

I have this link :
function new_message($chat_id,$user_id,$message,$recipient_ids)
http://www.demii.com/demo/dooponz/admin/index.php/chat/new_message/4/1/you/2%2C7
return chat_log_id
Can anyone please explain me how to call webserive by this get method or give me the
solution .
what i did with my code is below :
-(void)newMessage{
if ([self connectedToWiFi]){
NSString *urlString = [NSString stringWithFormat:#"www.demii.com/demo/dooponz/admin/index.php/chat/new_message/4/1/you/1,1,2"];
NSLog(#"urlString is %#", urlString);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *requestURL = [NSURL URLWithString:urlString];
[request setURL:requestURL];
[request setHTTPMethod:#"POST"];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSLog(#"ERROR = %#",error.localizedDescription);
if(error.localizedDescription == NULL)
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> succ %#",returnString);
[delegate ConnectionDidFinishLoading:returnString : #"newMessage"];
}
else
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> fail %#",returnString);
[delegate ConnectiondidFailWithError:returnString : #"newMessage"];
}
}];
}
}
how can i handle this ?
Thanks in advance .
I am not sure from your post whether or not you want to "post" or "get." However, gauging from the fact that you set your method to post, and that you are creating something new on your server, I am assuming you want to post.
If you want to post you can use my wrapper method for a post request.
+ (NSData *) myPostRequest: (NSString *) requestString withURL: (NSURL *) url{
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setTimeoutInterval:15.0];
NSData *requestBody = [requestString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
[request setHTTPBody:requestBody];
NSURLResponse *response = NULL;
NSError *requestError = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError];
return responseData;
}
Where request string is formatted like this:
NSString * requestString = [[NSString alloc] initWithFormat:#"username=%#&password=%#", userInfo[#"username"], userInfo[#"password"]];
This will also shoot back the response data which you can turn into a string like this.
responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
If you are trying to grab data from the server in json format...
+ (NSArray *) myGetRequest: (NSURL *) url{
NSArray *json = [[NSArray alloc] init];
NSData* data = [NSData dataWithContentsOfURL:
url];
NSError *error;
if (data)
json = [[NSArray alloc] initWithArray:[NSJSONSerialization
JSONObjectWithData:data
options:kNilOptions
error:&error]];
//NSLog(#"get results: \n %#", json);
return json;
}
Pls change ur code like this
-(void)newMessage{
NSString *urlString = [NSString stringWithFormat:#"http://www.demii.com/demo/dooponz/admin/index.php/chat/new_message/4/1/you/27" ];
NSLog(#"urlString is %#", urlString);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *requestURL = [NSURL URLWithString:urlString];
[request setURL:requestURL];
[request setHTTPMethod:#"POST"];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSLog(#"ERROR = %#",error.localizedDescription);
if(error.localizedDescription == NULL)
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> succ %#",returnString);
[self parseStringtoJSON:data];
//[delegate ConnectionDidFinishLoading:returnString : #"newMessage"];
}
else
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response >>>>>>>>> fail %#",returnString);
// [delegate ConnectiondidFailWithError:returnString : #"newMessage"];
}
}];
}
-(void)parseStringtoJSON:(NSData *)data{
NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
NSLog(#"chat id %#",[dict objectForKey:#"chat_log_id"]);
}
u will get the JSON response string as result if u hit that url. If u r familiar with json parsing, u can get the value based on key.
see this link: How do I deserialize a JSON string into an NSDictionary? (For iOS 5+)
I am passing some parameters to wcf service to get the data, every thing running fine but i am not getting the data. i want to check how the parameters are calling the service and debug it. can any one let me know how to check it.
please find my code below for your reference.
NSArray *propertyNames = [NSArray arrayWithObjects:#"studentID", nil];
NSArray *propertyValues = [NSArray arrayWithObjects:#"E6A83233-7D7F-49AF-B54E-375BBF3E3E59", nil];
NSDictionary *properties = [NSDictionary dictionaryWithObjects:propertyValues forKeys:propertyNames];
// NSMutableDictionary* personObject = [NSMutableDictionary dictionary];
// [personObject setObject:properties forKey:#"person"];
NSMutableArray * arr;
//[arr addObject: personObject];
arr=[[NSMutableArray alloc]initWithObjects:properties, nil];
NSLog(#"%#",arr);
// NSString *jsonString = [personObject JSONRepresentation];
//NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError * error;
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:arr options:NSJSONWritingPrettyPrinted error:&error];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://parentportal.technologyorg.com/parentportal.svc/GetSchoolEvents"]];
NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
[request setValue:jsonString forHTTPHeaderField:#"json"];
[request setHTTPMethod:#"Post"];
[request setHTTPBody:jsonData2];
NSLog(#"JSON String: %#",jsonString);
NSError *errorReturned = nil;
NSURLResponse *theResponse =[[NSURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
if (errorReturned) {
//...handle the error
NSLog(#"error");
}
else {
NSString *retVal = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
//...do something with the returned value
NSLog(#"RETVAL%#",retVal);
}
let me know if any thing went wrong
i am writing code for login application. can anyone help me how to parse a json string?
my code is
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSArray *loginDict = [parser objectWithString:loginDict error:nil];
[loginStatus release];
[connection release];
Example data:
NSString *strData = #"{\"1\": {\"name\": \"Jerry\",\"age\": \"12\"}, \"2\": {\"name\": \"Bob\",\"age\": \"16\"}}";
NSData *webData = [strData dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:webData options:0 error:&error];
NSLog(#"JSON DIct: %#", jsonDict);
NSLog output:
JSON DIct: {
1 = {
age = 12;
name = Jerry;
};
2 = {
age = 16;
name = Bob;
};
}
//*************Static Resopnse
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"demo" ofType:#"text"];

the result of this code is:json String is: {"json":{"Success":"Activation code."}}
After Conversation the result is ------- Dictionary value is {
Success = "Activation code."};
im new with objective-c. I have problem with memory leaking when developing iphone app. Leaking utility in Xcode shows that leaking problem with 'combArr'->'results' object. There is my function which parsing json from url and returns NSArray:
- (NSArray *)getListing2:(NSString *)item
from:(int)country {
//sending post request with some params
NSString *post = [#"product=" stringByAppendingString:item];
NSString *countryStr = [NSString stringWithFormat:#"&country=%d", country];
post = [post stringByAppendingString:countryStr];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *url = [prefs objectForKey:#"urlToApi"];
url = [url stringByAppendingString:#"/get-items/"];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
[request release];
//receiving json
NSString *jsonString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
SBJsonParser *json = [[SBJsonParser alloc] init];
NSError *error = nil;
//parsing json to nsdictionary
NSDictionary *results = [[NSDictionary alloc] initWithDictionary:[json objectWithString:jsonString error:&error]];
[json release];
[jsonString release];
//generate array of items
NSMutableArray *listOfItems = [[NSMutableArray alloc] init];
for (int i = 0; i < [[results objectForKey:#"data"] count]; i++) {
[listOfItems addObject:[[results objectForKey:#"data"] objectForKey:[NSString stringWithFormat:#"%d", i]]];
}
//saving items array and count info object into one array
NSArray * returnArr = [[[NSArray arrayWithObjects:listOfItems, [results valueForKey:#"count_info"], nil] retain] autorelease];
[listOfItems release];
[results release];
return returnArr;
}
And i executing this function here:
myApi *itemsApi = [[myApi alloc] init];
NSArray *combArr = [[izdApi getListing2:item from:countryId] retain];
[itemsApi release];
listOfItems = [[combArr objectAtIndex:0] retain];
if([listOfItems count] > 0){
priceArr = [[combArr objectAtIndex:1] retain];
}
else{
totalCount = 0;
}
[combArr release];
Thank you for helping
Every time you allocate memory, you must release it. (alloc, copy, retain).
You are releasing myApi, not itemsApi. Try this...
myApi *itemsApi = [[itemsApi alloc] init];
NSArray *combArr = [[izdApi getListing2:item from:countryId] retain];
[itemsApi release];
listOfItems = [[combArr objectAtIndex:0] retain];
if([listOfItems count] > 0){
priceArr = [[combArr objectAtIndex:1] retain];
}
else{
totalCount = 0;
}
[combArr release];
If you are using Xcode 4, Try turning on ARC. In short, ARC handles the releasing of all memory. A little burden off your shoulders and one less thing for you to worry about.
I have fetched the JSON data i want to store all the information like in a Book class object book and the use them by book.title etc.
I am using following code
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.krsconnect.no/community/api.html?method=bareListEventsByCategory&appid=620&category-selected=350&counties-selected=Vest-Agder,Aust-Agder"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *object = [parser objectWithString:json_string error:nil];
NSArray *results = [parser objectWithString:json_string error:nil];
NSDictionary *dictOne = [results objectAtIndex:0];
/*
NSArray *activitiesArray = [dictOne objectForKey:#"events"];
NSDictionary *dictTwo = [activitiesArray objectAtIndex:0];
NSLog(#"%# - %#", [dictOne objectForKey:#"date"]);
NSLog(#"%# - %#", [dictTwo objectForKey:#"affectedDate"]);
*/
appDelegate.books = [[NSMutableArray alloc] init];
NSArray *activitiesArray = [dictOne objectForKey:#"events"];
NSDictionary *dictTwo = [activitiesArray objectAtIndex:0];
NSLog(#"%# - %#", [dictOne objectForKey:#"date"]);
NSLog(#"%# - %#", [dictTwo objectForKey:#"affectedDate"]);
I want to do like this store the data in an array but its not working
NSArray *results = [parser objectWithString:json_string error:nil];
for (int i=0; i<[results count]; i++) {
Book *aBook = [[Book alloc] initWithDictionary:[results objectAtIndex:i]];
[appDelegate.books addObject:aBook];
[aBook release];
}
