I want to convert this to JSON object. So I did like this.
NSError *jsonError;
NSData *objectData = [[[[dm.mutArraySelectedReq objectAtIndex:index] objectForKey:#"RequestDetails"] valueForKey:#"RequestForm"] dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
but my jsondictionary is always nil. What is the error with this RequestForm object.
Please help me.
Thanks
UPDATE
This is the string I want to convert into a json.

Remove " " from key string in a NSMutableDictionary
Here's my dictionary:
Birthdate = "01-01-0001";
CareerField = 3;
Gender = 2;
"Interests[0].UserProfileId" = 19594;
"Interests[0].UserSurveyId" = 1;
SocialStatus = 2;
Studies = 3;
But I want the Interests key to be without "".Like that:
Birthdate = "01-01-0001";
CareerField = 3;
Gender = 2;
Interests[0].UserProfileId = 19594;
Interests[0].UserSurveyId = 1;
SocialStatus = 2;
Studies = 3;
UPDATE:
Interests i must send them like array.
[dict setObject:self.birthdayDate forKey:#"Birthdate"]
[dict setObject:#(self.occupationPickerRow + 1) forKey:#"CareerField"];
for (int i = 0; i < [interestsArray count]; i++) {
NSString *stringSurveyId = [NSString stringWithFormat:#"%#%d%#", #"Interests[", indexCount, #"].UserSurveyId"];
NSString *stringUserProfileId = [NSString stringWithFormat:#"%#%d%#", #"Interests[", indexCount, #"].UserProfileId"];
[dict setObject:[interestsArray objectAtIndex:i] forKey:stringSurveyId];
[dict setObject:#([[[MZEngine sharedInstance] currentUserModel] userId]) forKey:stringUserProfileId];
indexCount++;
}

This is the response i am getting from json, what logic should i write to retrieve "VideoId" linked to a specific "Speciality" (for ex- Speciality = 22)
if i write following code, i am getting all #"VideoId"
[[[[responseDictionary valueForKey:#"Data"]valueForKey:#"Specialities"]valueForKey:#"Videos"]valueForKey:#"VideoId"]
The parsing way will be something like:
NSDictionary *dataDict = [responseDictionary valueForKey:#"Data"];
NSMutableArray *specialityArray = [dataDict valueForKey:#"Specialities"];
NSDictionary *objectDict = [specialityArray objectAtIndex:your index (0/1/2)];
int *speciality = [[objectDict ValueForKey:#"Speciality"] intValue];
if(speciality = 22)
{
NSMutableArray *videoArray = [objectDict valueForKey:#"Videos"];
NSDictionary *videoObject = [videoArray objectAtIndex:your index (0/1/2)];
NSString *videoID = [videoObject valueForKey:#"VideoId"];
}
Parse the rest accordingly as per your need.
Use this code,
NSArray *wholeArray = [[responseDictionary objectForKey:#"Data"] valueForKey:#"Specialities"];
NSArray *subArray = [[wholeArray objectAtIndex:0] valueForKey:#"Videos"];
subArray is get all the videos values, then you get single value use this code,
NSString *videoID = [[subArray objectAtIndex:i] valueForKey:#"VideoId"];
or you will get all videoID in single variable use this below code,
NSMutableArray *tempArray = [[NSMutableArray alloc] init];
for (int i = 0; i < subArray.count; i++) {
[tempArray addObject:[[subArray objectAtIndex:i] valueForKey:#"VideoId"]];
}
finally tempArray get All the VideoID values, anywhere you use,
NSString *videoID = [tempArray objectAtIndex:0/1/2];
hope its helpful
Issues parsing a dictionary
Below is a dictionary I have created by retrieving the my twitter statuses for an App Only twitter feed. I have parsed and returned the value of "text" successfully, and displayed it in a table view cell as follows:
static NSString *cellID = #"FeedCell3" ;
FeedCell3 *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {
cell = [[FeedCell3 alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
NSInteger idx = indexPath.row;
NSDictionary *t = self.twitterDataSource[idx];
cell.updateLabel.text = t[#"text"];
return cell;
However, when I try to return other values for keys such as "profile_image_url" and "screen_name" using the method below, an (null) is returned, even though there is a value in the dictionary. What am I doing wrong?
cell.nameLabel.text = t[#"screen_name"];
NSURL *profileImageURL = t[#"profile_image_url"];
NSLog(#"%#", profileImageURL);

Those latter two keys you're going for are in the user dictionary, so try t[#"user"][#"screen_name"]; t[#"user"][#"profile_image_url"]; The second issue will appear when you solve the first. The url is a string. To get a proper NSURL you'll need to use an NSURL class method. NSURL *aURL = [NSURL URLWithString:t[#"user"][#"profile_image_url"]];
Merge the same objects inside array IOS
I have an array which contains this objects:
(
{
aOptns = (
);
fCustomDscnt = 0;
fPrcntDscnt = 0;
fPrice = 0;
fQty = 1;
iItemDayPriceId = 143;
iShiftId = 1;
sItemName = "";
sModifier = "";
},
{
aOptns = (
);
fCustomDscnt = 0;
fPrcntDscnt = 0;
fPrice = 0;
fQty = 1;
iItemDayPriceId = 143;
iShiftId = 1;
sItemName = "";
sModifier = "";
},
{
aOptns = (
);
fCustomDscnt = 0;
fPrcntDscnt = 0;
fPrice = 0;
fQty = 1;
iItemDayPriceId = 143;
iShiftId = 1;
sItemName = "";
sModifier = "";
},
{
aOptns = (
);
fCustomDscnt = 0;
fPrcntDscnt = 0;
fPrice = 0;
fQty = 1;
iItemDayPriceId = 112;
iShiftId = 1;
sItemName = "";
sModifier = "";
}
)
I need to merge the contents of array if the objects are same and modify the object inside that array in such a way that it should be like this:
(
{
aOptns = (
);
fCustomDscnt = 0;
fPrcntDscnt = 0;
fPrice = 0;
fQty = 3;
iItemDayPriceId = 143;
iShiftId = 1;
sItemName = "";
sModifier = "";
},
{
aOptns = (
);
fCustomDscnt = 0;
fPrcntDscnt = 0;
fPrice = 0;
fQty = 1;
iItemDayPriceId = 112;
iShiftId = 1;
sItemName = "";
sModifier = "";
}
)
As you can see, the entry for object with iItemDayPriceId = 143 becomes 1 only with fQty = 3.
I have tried using the code here: How to Find Duplicate Values in Arrays?
But it is only comparing 2 objects at a time.
Edit: Oops, I missed your count requirement.
Edit 2: And the fact that you wanted to mutate the given array rather the build a new one.
Depends on what you mean by distinct but since it looks like you mean to compare the contents and not the references, you should build a new array so that if the comparison is true you increment the count and otherwise you add the object.
Mutate existing array
Disclaimer: probably not my best work here.
I would appreciate if someone could suggest how to improve this because I am pretty sure it is not the best way to do this and may not even work (don't have access to an Obj-C compiler at the moment).
Foo objectA = [Foo new];
objectA.Bar = #"Bar";
Foo objectB = [Foo new];
objectB.Bar = #"Bar";
Foo objectC = [Foo new];
objectC.Bar = #"Not Bar";
NSMutableArray *array = #[objectA, objectB, objectC];
NSMutableDictionary *countDictionary = [[NSMutableDictionary alloc] init];
for (Foo *foo in [array copy])
{
bool found = false;
for (Foo *key in countDictionary)
{
if ([key isEqualTo:foo])
{
NSNumber *currentCount = [countDictionary objectForKey:key];
int currentIntCount = [currentCount intValue];
currentIntCount++;
[countDictionary setObject:[NSNumber numberWithInt:currentIntCount] forKey:key];
[array removeObject:key];
found = true;
break;
}
if (!found)
[countDictionary setObject:[NSNumber numberWithInt:1] forKey:foo];
}
}
for (Foo *realFoo in array)
{
NSNumber *countNumber = [countDictionary objectForKey:realFoo];
int countInt = [countNumber intValue];
realFoo.Count = countInt;
}
Build new array
Foo objectA = [Foo new];
objectA.Bar = #"Bar";
Foo objectB = [Foo new];
objectB.Bar = #"Bar";
NSMutableArray *array = #[objectA, objectB];
NSMutableArray *distinct = [[NSMutableArray alloc] init];
for (Foo *f in array)
{
bool found = false;
for (Foo *d in distinct)
{
if ([d isEqualTo:f])
{
found = true;
d.Count++;
}
break;
}
if (!found)
[distinct addObject:f];
}
And of course you would have to define an equality comparer for Foos, in this case for instance
-(bool) isEqualTo:(Foo *)nFoo
{
bool isEqual = false;
if ([self.Bar isEqualToString:nFoo.Bar])
isEqual = true;
return isEqual;
}
Having not dealt with Objective C in a while I should say that there may be some best-practices as to implementing equality comparison instead of rolling your own completely like this example
Use below code: NSMutableArray* myArray = [[NSMutableArray alloc]initWithObjects: #"red",#"blue",#"red",#"green",#"yellow", #"33", #"33",#"red", #"123", #"123",nil]; NSOrderedSet *mySet = [[NSOrderedSet alloc] initWithArray:myArray]; myArray = [[NSMutableArray alloc] initWithArray:[mySet array]]; NSLog(#"%#",myArray);

This will illustarate your problem
Get data rx in _recievedData then check the class of the object.
id object = [NSJSONSerialization
JSONObjectWithData:_recievedData
options:kNilOptions
error:&error];
if (error)
{
NSLog(#"Error in rx data:%#",[error description]);
}
if([object isKindOfClass:[NSString class]] == YES)
{
NSLog(#"String rx from server");
}
else if ([object isKindOfClass:[NSDictionary class]] == YES)
{
NSLog(#"Dictionary rx from server");
}
else if ([object isKindOfClass:[NSArray class]] == YES)
{
NSLog(#"Array rx from server");
}
This should help you.
id object = [responseData objectForKey:#"artists"];
if ([object isMemberOfClass:[NSString class]]) {
// do the stuff for NSString
}
else if ([object isMemberOfClass:[NSArray class]]) {
// do the stuff for NSArray
}
