JSOn parsing data shows different values for same object in iphone - iphone

When i NSLog affecteddate values it shows correct but when i store it in var it gives wrong value
SBJsonParser *parser= [[SBJsonParser alloc] init];
NSString *url = [NSString stringWithFormat:#"http://www.krsconnect.no/community/api.html?method=bareListEventsByCategory&appid=620&category-selected=%#&counties-selected=Vest-Agder,Aust-Agder&range=0-10", test];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
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];
appDelegate.books1 = [[NSMutableArray alloc] init];
appDelegate.dates =[[NSMutableArray alloc]init];
appDelegate.books2=[[NSMutableArray alloc]init];
appDelegate.books3=[[NSMutableArray alloc]init];
appDelegate.books4=[[NSMutableArray alloc]init];
appDelegate.books5=[[NSMutableArray alloc]init];
appDelegate.books6=[[NSMutableArray alloc]init];
appDelegate.books7=[[NSMutableArray alloc]init];
appDelegate.books8=[[NSMutableArray alloc]init];
appDelegate.books9=[[NSMutableArray alloc]init];
appDelegate.books10=[[NSMutableArray alloc]init];
NSArray *activitiesArray;
mycount=[results count];
for (int j=0;j<[results count]; j++) {
NSDictionary *dictOne = [results objectAtIndex:j];
NSLog(#"%# - %#", [dictOne objectForKey:#"date"]);
Date *aDate = [[Date alloc] initWithDictionary:[results objectAtIndex:j]];
[appDelegate.dates addObject:aDate];
[aDate release];
activitiesArray = [dictOne objectForKey:#"events"];
for (int i=0; i<[activitiesArray count]; i++) {
int testcount =[activitiesArray count];
NSDictionary *dictTwo = [activitiesArray objectAtIndex:i];
NSDictionary *eventDict=[dictTwo objectForKey:#"event"];
// NSLog(#"%# - %#", [dictOne objectForKey:#"date"]);
// NSLog(#"%# - %#", [dictTwo objectForKey:#"affectedDate"]);
// NSLog(#"%# - %#", [eventDict objectForKey:#"location"]);
NSInteger*date=[dictTwo objectForKey:#"affectedDate"];
NSInteger*affecteddate=[dictTwo objectForKey:#"affectedDate"];
NSLog(#"%# - %#", [dictTwo objectForKey:#"affectedDate"]);
NSString*appId =[eventDict objectForKey:#"appId"];
NSLog(#"%# - %#", [eventDict objectForKey:#"eventId"]);
NSInteger*eventId=[eventDict objectForKey:#"eventId"];
int next=[affecteddate intValue];
int next_int = [eventId intValue];
NSString*location=[eventDict objectForKey:#"location"];
NSString*municipality=[eventDict objectForKey:#"municipality"];
NSString*title=[eventDict objectForKey:#"title"];
Book1 *aBook=[[Book1 alloc] initWithDate:date affecteddate:affecteddate eventId:eventId location:location municipality:municipality title:title];
Book1 class
#interface Book1 : NSObject {
NSInteger*date;
NSInteger*affecteddate;
NSString *title;
NSString *location;
NSString *municipality;
NSInteger eventId;
NSString* event;
}
#property(nonatomic,readwrite) NSInteger eventId;
#property(nonatomic,retain) NSString* event;
#property(nonatomic) NSInteger *date;
#property(nonatomic,readwrite)NSInteger* affecteddate;
#property(nonatomic,retain)NSString *title;
#property(nonatomic,retain) NSString *location;
#property(nonatomic,retain) NSString *municipality;
-(id)initWithDate:(NSInteger *)d affecteddate:(NSInteger *)ad eventId:(NSInteger*)eId location:(NSString *)l municipality:(NSString *)m title:(NSString *)t ;
#end

First you have:
NSInteger*affecteddate=[dictTwo objectForKey:#"affectedDate"];
later
int next=[affecteddate intValue];
intValue is not valid on an integer
You probably want:
NSNumber *date = [dictTwo objectForKey:#"affectedDate"];
NSNumber *affecteddate = [dictTwo objectForKey:#"affectedDate"];
may declare like this in book object to assign this values
NSNumber *affecteddate;
#propert(nonatomic,retain)

How to copy custom NSObject into NSMutableArray

NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseData
options:kNilOptions
error:&error];
NSArray* users = [json objectForKey:#"Users"];
NSEnumerator* enumerator = [users objectEnumerator];
id element;
NSMutableArray *results;
Result *fetchedResults;
while(element = [enumerator nextObject]) {
// fetchedResults = [[Result alloc] init]; // i have tried commenting/uncommenting
fetchedResults.name = (NSString *)[[element objectForKey:#"User"] objectForKey:#"name"];
fetchedResults.email = (NSString *)[[element objectForKey:#"User"] objectForKey:#"name"];
NSLog(#"%#", fetchedResults.name);
[results addObject:fetchedResults];
NSLog(#"%#", (NSString *)[[element objectForKey:#"User"] objectForKey:#"name"]); // this returns valid dump
}
NSLog(#"%d", [results count]); // returns 0
I don't understand wht's wrong here. I have searched through numerous tutorials and resources don't seem to get what's wrong here.
EDIT:
NSLog(#"%#", fetchedResults.name); // dumps null
You forgot to allocate your results array NSMutableArray *results = [[NSMutableArray alloc] init] this should help.
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseData
options:kNilOptions
error:&error];
NSArray* users = [json objectForKey:#"Users"];
NSMutableArray *results = [[NSMutableArray alloc] init];
for (id object in users) {
Result *fetchedResults = [[Result alloc] init];
fetchedResults.name = (NSString *)[[element objectForKey:#"User"] objectForKey:#"name"];
fetchedResults.email = (NSString *)[[element objectForKey:#"User"] objectForKey:#"name"];
NSLog(#"%#", fetchedResults.name);
[results addObject:fetchedResults];
}
NSLog(#"%#", (NSString *)[[element objectForKey:#"User"] objectForKey:#"name"]);
}
NSLog(#"%d", [results count]); // returns 0

But my app crashes with "Program received EXC_BAD_ACCESS" error at any line where I am using "ABRecordCopyValue" function . What I am missing? I am not getting whats wrong in my code?
I tried setting NSZombieEnabled = YES , but its not showing any message. Just saying "Program received EXC_BAD_ACCESS" at any line using ABRecordCopyValue function & in console I see (gdb) thats it.
Any knid of help is highly appreciated. Thanks.

how to capture the required values from a URL

I need to extract a variable's value from a string, which happens to be a URL. The string/url is loaded as part of a separate php query, not the url in the browser.
The url's will look like:
http://gmail.com?access_token=ab8w4azq2xv3dr4ab37vvzmh&token_type=bearer&expires_in=3600
How can I capture the value of the access_token which in this example is ab8w4azq2xv3dr4ab37vvzmh?
This code should do it:
- (NSString *)extractToken:(NSURL *)URL
{
NSString *urlString = [URL absoluteString];
NSRange start = [urlString rangeOfString:#"access_token="];
if (start.location != NSNotFound)
{
NSString *token = [urlString substringFromIndex:start.location+start.length];
NSRange end = [token rangeOfString:#"&"];
if (end.location != NSNotFound)
{
//trim off other parameters
token = [token substringToIndex:end.location];
}
return token;
}
//not found
return nil;
}
Alternatively, here is a more general solution that will extract all the query parameters into a dictionary:
- (NSDictionary *)URLQueryParameters:(NSURL *)URL
{
NSString *queryString = [URL query];
NSMutableDictionary *result = [NSMutableDictionary dictionary];
NSArray *parameters = [queryString componentsSeparatedByString:#"&"];
for (NSString *parameter in parameters)
{
NSArray *parts = [parameter componentsSeparatedByString:#"="];
NSString *key = [[parts objectAtIndex:0] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
if ([parts count] > 1)
{
id value = [[parts objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[result setObject:value forKey:key];
}
}
return result;
}
Good Category for NSDictionary:
#import "NSDictionary+URL.h"
#implementation NSDictionary (URL)
+ (NSDictionary *)dictionaryWithUrlString:(NSString *)urlString{
NSRange urlRange = [urlString rangeOfString:#"?"];
if(urlRange.length>0){
urlString = [urlString substringFromIndex:urlRange.length+urlRange.location];
}
NSArray *pairsArray = [urlString componentsSeparatedByString:#"&"];
NSMutableDictionary *parametersDictionary = [[NSMutableDictionary alloc] initWithCapacity:[pairsArray count]];
for(NSString *pairString in pairsArray){
NSArray *valuesArray = [pairString componentsSeparatedByString:#"="];
if([valuesArray count]==2){
[parametersDictionary setValue:[valuesArray objectAtIndex:1] forKey:[valuesArray objectAtIndex:0]];
}
}
return [parametersDictionary autorelease];
}
#end
NSMutableDictionary *querycomponent = [[NSMutableDictionary alloc] init];
if (![query isEqualToString:#""]){
NSArray *queryArray = [query componentsSeparatedByString:#"&"];
for (NSString *subquery in queryArray){
NSArray *subqueryArray = [subquery componentsSeparatedByString:#"="];
NSString *key = [subqueryArray objectAtIndex:0];
NSString *val = [subqueryArray objectAtIndex:1];
[querycomponent setObject:val forKey:key];
}
NSLog(#"querycomponent %#",querycomponent);
}

displaying JSON data in Tableview in iphone

below is the JSON i want to parse it in such a way that for e.g date 1st should all events in that section of table and 2nd date should show all related events in another section
I am parsing using below code but i am not getting required sequence
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];
appDelegate.books1 = [[NSMutableArray alloc] init];
appDelegate.dates =[[NSMutableArray alloc]init];
for (int j=0;j<10; j++) {
NSDictionary *dictOne = [results objectAtIndex:j];
NSLog(#"%# - %#", [dictOne objectForKey:#"date"]);
Date *aDate = [[Date alloc] initWithDictionary:[results objectAtIndex:j]];
[appDelegate.dates addObject:aDate];
[aDate release];
}
for (int i=0; i<10; i++) {
NSDictionary *dictOne = [results objectAtIndex:i];
NSArray *activitiesArray = [dictOne objectForKey:#"events"];
NSDictionary *dictTwo = [activitiesArray objectAtIndex:i];
NSDictionary *eventDict=[dictTwo objectForKey:#"event"];
// NSLog(#"%# - %#", [dictOne objectForKey:#"date"]);
// NSLog(#"%# - %#", [dictTwo objectForKey:#"affectedDate"]);
// NSLog(#"%# - %#", [eventDict objectForKey:#"location"]);
NSInteger*date=[dictOne objectForKey:#"date"];
NSInteger*affectedDate=[dictTwo objectForKey:#"affectedDate"];
NSString*appId =[eventDict objectForKey:#"appId"];
NSString*eventId=[eventDict objectForKey:#"eventId"];
NSString*location=[eventDict objectForKey:#"location"];
NSString*municipality=[eventDict objectForKey:#"municipality"];
NSString*title=[eventDict objectForKey:#"title"];
Book1 *aBook=[[Book1 alloc] initWithDate:date affectedDate:affectedDate location:location municipality:municipality title:title];
[appDelegate.books1 addObject:aBook];
int count=[appDelegate.books1 count];
}
the json format is given below
http://www.krsconnect.no/community/api.html?method=bareListEventsByCategory&appid=620&category-selected=350&counties-selected=Vest-Agder,Aust-Agder
You need to aggregate your data in some different way.
Here is how I'd do that:
...
// why do you parse your json string two times?
//NSDictionary *object = [parser objectWithString:json_string error:nil];
NSArray *results = [parser objectWithString:json_string error:nil];
// You have memory leak here. I assume that books1 and dates are both properties with "retain" flag set.
//appDelegate.books1 = [[NSMutableArray alloc] init];
//appDelegate.dates =[[NSMutableArray alloc]init];
NSMutableArray *data = [NSMutableArray array]
self.data = data;
// check that what we've parsed is NSArray
if (results && [results isKindOfClass:[NSArray class]]) {
for (NSDictionary *sectionDict in results) {
if ([sectionDict isKindOfClass:[NSDictionary class]]) {
NSString *sectionTitle = [[sectionDict objectForKey:#"date"] description];
NSArray *events = [sectionDict objectForKey:#"events"];
if (date && events && [events isKindOfClass:[NSArray class]]) {
NSMutableArray *rows = [NSMutableArray arrayWithCapacity:[events count]];
for (NSDictionary *eventDict in events) {
if ([eventDict isKindOfClass:[NSDictionary class]]) {
[rows addObject:#"testRow"];
}
}
[data addObject:[NSDictionary dictionaryWithObjectsAndKeys: sectionTitle, #"section", rows, #"rows", nil]];
}
}
}
}
- (NSInteger) numberOfSectionsInTableView:(UITableView *)tblView {
return [data count];
}
- (NSInteger) tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section {
return [[[data objectAtIndex:section] objectForKey:#"rows"] count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [[data objectAtIndex:section] objectForKey:#"section"];
}
- (UITableViewCell *) tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellID = #"DefaultCell";
UITableViewCell *cell = (UITableViewCell *)[tblView dequeueReusableCellWithIdentifier:cellID];
if ( cell == nil ) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID] autorelease];
}
cell.textLabel.text = [[[data objectAtIndex:indexPath.section] objectForKey:#"rows"] objectAtIndex:indexPath.row];
return cell;
}

The NSMutableArray listofItems has 3 values.So how can i extract the array value in another method?
Help me
Fast enumeration is the preferred method.
for (id object in listOfItems) {
//Do something...
}
If you want a single object at an index:
id object = [listOfItems objectAtIndex:someIndex];
If you just want an object (expecting the array to have a single object:
id object = [listOfItems lastObject];
for(int i=0; i < [listOfItems count]; ++i) {
Restaurant* r = [listofItems objectAtIndex:i];
}
