I need to get JSON response array all indexes values and maintain separate array. Here below I have posted my JSON response and I wanted to get console output looks like below also. Please help me.
response : [ {
A = [ {
name : "sons";
age = [
4
];
},
{
name : "rondo";
age = [
2
];
},
];
} ]
I need to store separate array separate values looks like below console output
2014-09-18 10:24:39.461 Myapp[1133:60b] RESULT : {
name = "sons";
age = 4;
}
2014-09-18 10:24:39.462 Myapp[1133:60b] RESULT : {
name = "rondo";
age = 2;
}
Here below I tried but I Know I can get only 0th index value but I need to get all index value from JSON response array:
myvalue = [NSString stringWithFormat:#"%#",[[[[responsData objectAtIndex:0] valueForKey:#"A"] objectAtIndex:0] valueForKey:#"name"]];
if you want to get all objects, get the array using the respective key.Then store the result in another array by iterating the for loop according to array count.
NSArray *recordsArr = [[responsedata objectAtIndex:0] valueForKey:#"A"];
NSMutableArray *resultArray = [[NSMutableArray alloc] init];
for (int i = 0; i < [recordsArr count]; i ++) {
NSMutableDictionary *recordDict = [[NSMutableDictionary alloc] init];
[recordDict setObject:[[recordsArr objectAtIndex:i] valueForKey:#"name"] forKey:#"name"];
[recordDict setObject:[[[recordsArr objectAtIndex:i] valueForKey:#"age"] objectAtIndex:0] forKey:#"age"];
[resultArray addObject:recordDict];
}
NSLog(#"%#",resultArray);
output:
2014-09-18 12:49:22.047 testprj[1044:60b] (
{
age = 4;
name = sons;
},
{
age = 2;
name = rondo;
}
)
NSString *strName = (NSString *) [yourArray valueForKey:#"name"];
NSInteger age = [(NSNumber *) [yourArray valueForKey:#"age"] integerValue];

I have an NSMutableArray that contains an object of a class model in each position like this.
The class model contains 2 types of information, which we will call id and name.
So, in every location of my NSMutableArray I have an object that contains 2 information.
Then, in the first position of my NSMutableArray I have
{
id = 1;
name = "Dan"; //this is the first object in NSMutableArray
}
In the second position of NSMutableArray, I have:
{
id = 1;
name = "Luca";
}
In the third position
{
id = 2;
name = "Tom";
}
and so on..
Ok, my goal is to make the union of identical IDs between the various objects within the SNMutableArray but it's too difficult!
For example, if I have:
{
id = 1;
name = "Tom";
}
{
id = 1;
name = "Luca";
}
{
id = 2;
name = "Steve";
}
{
id = 2;
name = "Jhon";
}
{
id = 3;
name = "Andrew";
}
The goal is:
{
id = 1;
name = "Tom";
name = "Luca";
}
{
id = 2;
name = "Steve";
name = "Jhon";
}
{
id = 3;
name = "Andrew";
}
Any ideas? would like to use this in the cellForRowAtIndexPath method and I tried to write this: (cm is my class model and myArray is the NSMutableArray which contains an object of cm class)
ClassModel *cm = [myArray objectAtIndex:indexPath.row];
NSMutableArray * resultArray = [NSMutableArray new];
NSArray * groups = [array valueForKeyPath:cm.ID];
for (NSString * groupId in groups)
{
NSMutableDictionary * entry = [NSMutableDictionary new];
[insert setObject: groupId forKey: # "groupId"];
NSArray * groupNames = [array filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: # "groupId =% #", groupId]];
for (int i = 0; i <groupNames.count; i ++)
{
NSString * name = [[groupNames objectAtIndex: i] objectForKey: # "name"];
[entry setObject: name forKey: [NSS string stringWithFormat: # "name% d", i + 1]];
}
[resultArray addObject: entry];
}
NSLog (# "% #", resultArray);
But this does not work..maybe because each element in my array is an object?? .. Help!
You have the right basic idea, but you shouldn't try and do this in cellForRowAt. Rather, you need to create a new array that has the data in the required structure and use that array as the source for your tableview. You will also need to create a new class to put in the array; one that has an id and an NSMutableArray for the names (I won't show this but I will call it GroupClassModel)
Use something like:
NSMutableDictionary *groups = [NSMutableDictionary new]
for (ClassModel *cm in array) {
GroupClassModel *gcm = groups[cm.id];
if (gcm == nil) {
gcm = [GroupClassModel new];
gcm.id = cm.id
groups[cm.id] = gcm
}
[gcm.names addObject:cm.name];
}
NSArray *groupedName = [groups allValues];
// Finally, sort groupedName by id if that is required.
I've read and tried a dozen or more variants of my own question, but still need some help please.
I have a large existing array, and I want to add a new object (key and value) to each record.
This is an element in the incoming array:
{
"trip_id": 65,
"arrival_time": "08:56:08",
"departure_time": "08:56:08",
"stop_id": 1161,
"stop_sequence": 8,
"stop_headsign": 0
},
This is what I want to achieve:
{
"trip_id": 65,
"arrival_time": "08:56:08",
"departure_time": "08:56:08",
"stop_id": 1161,
"stop_name": "a stop name",
"stop_sequence": 8,
"stop_headsign": 0
},
This is my code so far -- the commented lines are other attempts:
NSString *nameKey = #"stop_name";
int i=0;
for (i=0; i<stopTimesArray.count; i++) {
NSNumber *stopTimesId = [stopTimesArray[i] valueForKey:#"stop_id"];
int j=0;
for (j=0; j<stopArray.count; j++) {
NSNumber *stopId = [stopArray[j] valueForKey:#"stop_id"];
if (stopId == stopTimesId) {
NSString *stopNameString = [stopArray[j] valueForKey:#"stop_name"];
NSLog(#"stopNameString: %#", stopNameString);
[outgoingStopTimesDictionary setObject:stopNameString forKey:#"stop_name"];
//[outgoingStopTimesArray addObject:outgoingStopTimesDictionary];
//[outgoingStopTimesArray addObjectsFromArray:stopTimesArray[i]];
//[stopTimesArray[i] addObject:#{#"stop_name":stopNameString}];
//[stopTimesArray[i] addObject:#{#"stop_name":stopNameString}];
[stopTimesArray[i] addObject: outgoingStopTimesDictionary];
}
}
}
//NSLog(#"outgoingStopTimesArray: %#", outgoingStopTimesArray);
//NSLog(#"outgoingStopTimesDictionary: %#", outgoingStopTimesDictionary);
//NSLog(#"stopTimesArray: %#", stopTimesArray);
The error I am getting with approach is:
stopNameString: S Monroe Street, NB # 18th Street S, NS
[__NSCFDictionary addObject:]: unrecognized selector sent to instance 0x7fd7f2c22760
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary addObject:]: unrecognized selector sent to instance 0x7fd7f2c22760'
I'm either getting a null dictionary, or an unrecognised object exception when I try to add the dictionary to my array. Please point me to a working answer, and I'll delete my question.
It appears that your goal is to add one new key/value pair to the dictionary at stopTimesArray[i]. Here's your code all cleaned up with what I believe you need:
for (NSMutableDictionary *stopTimesDictionary in stopTimesArray) {
NSNumber *stopTimesId = stopTimesDictionary[#"stop_id"];
for (NSDictionary *stopDictionary in stopArray) {
NSNumber *stopId = stopDictionary[#"stop_id"];
if ([stopTimesId isEqual:stopId]) {
NSString *stopNameString = stopDictionary[#"stop_name"];
stopTimesDictionary[#"stop_name"] = stopNameString;
// Uncomment the following line if "stop_id" is unique within the "stopArray"
// break;
}
}
}
Since it seems your stopTimesArray contains immutable dictionaries, the above code won't work as written. Here is a solution that deals with that:
for (NSInteger i = 0; i < stopTimesArray.count; i++) {
NSDictionary *stopTimeDictionary = stopTimesArray[i];
NSNumber *stopTimesId = stopTimesDictionary[#"stop_id"];
for (NSDictionary *stopDictionary in stopArray) {
NSNumber *stopId = stopDictionary[#"stop_id"];
if ([stopTimesId isEqual:stopId]) {
NSString *stopNameString = stopDictionary[#"stop_name"];
NSMutableDictionary *tempDict = [stopTimesDictionary mutableCopy];
tempDict[#"stop_name"] = stopNameString;
[stopTimesArray replaceObjectAtIndex:i withObject:tempDict];
// Uncomment the following line if "stop_id" is unique within the "stopArray"
// break;
}
}
}
dictTo=[NSDictionary new];
dictTo =
#{
#"vPLocationLat" : [NSString stringWithFormat:#"%#",[[[[json valueForKey:#"result"] valueForKey:#"geometry"] valueForKey:#"location"] valueForKey:#"lat"]],
#"vPLocationLong" : [NSString stringWithFormat:#"%#",[[[[json valueForKey:#"result"] valueForKey:#"geometry"] valueForKey:#"location"] valueForKey:#"lng"]]
};
arrLocationList =[NSMutableArray new];
arrLocationList =[dictTo[#"data"] mutableCopy];
another Solution
-> Try to implement your Code as per in given Code
NSMutableArray* newArray = [NSMutableArray array];
NSArray* oldArray = outerDictionary[#"scores"];
for (NSDictionary* dictEntry in oldArray) {
NSString* leagueCode = dictEntry[#"league_code"];
if ([leagueCode isEqualToString #"epl"]) {
[newArray addObject:dictEntry];
}
}
Another one Solution
Try something like this.
Assume your array is called array and yourNewNameString is your new value for name
for(NSMutableDictionary *dict in array){
if([[dict objectForKey:#"id"]integerValue]==5){
[dict setObject:yourNewNameString forKey#"name"];
}
}
edit This is assuming you initialized your array with NSMutableDictionarys (Not just NSDictionarys)
//You can create dictionary and add it into NSMutableArray Object Like..
NSMutableArray *arr = [[NSMutableArray alloc] init];
NSDictionary *inventory = #{
#"Mercedes-Benz SLK250" : [NSNumber numberWithInt:13],
#"Mercedes-Benz E350" : [NSNumber numberWithInt:22],
#"BMW M3 Coupe" : [NSNumber numberWithInt:19],
#"BMW X6" : [NSNumber numberWithInt:16],
};
[arr addObject:inventory];
//You can access using key like...
NSString *strForBMWX6 = [[arr objectAtIndex:0] valueForKey:#"BMW X6"];
// in your case you just miss objectAtIndex:j
First, thanks #rmaddy.
I modified his answer a bit, but his was basically correct.
My final code looks like this:
for (NSInteger i = 0; i < stopTimesArray.count; i++) {
NSDictionary *stopTimesDictionary = stopTimesArray[i];
NSNumber *stopTimesId = stopTimesDictionary[#"stop_id"];
for (NSDictionary *stopDictionary in stopArray) {
NSNumber *stopId = stopDictionary[#"stop_id"];
if ([stopTimesId isEqual:stopId]) {
NSString *stopNameString = stopDictionary[#"stop_name"];
NSMutableDictionary *tempDict = [stopTimesDictionary mutableCopy];
tempDict[#"stop_name"] = stopNameString;
[outgoingStopTimesArray addObject:tempDict];
break;
}
}
}
I have an NSDictionary with the following data:
(lldb) po allFriends
{
71685207018702188 = {
id = 71685207018702188;
name = "mikeziri ";
username = mi;
};
93374822540641772 = {
id = 93374822540641772;
name = "Alan Weclipse";
username = zuka;
};
96553685978449395 = {
id = 96553685978449395;
name = "Monica Weclipse";
username = amonica;
};
96556113096345076 = {
id = 96556113096345076;
name = Xavier;
username = branko;
};
97017008427632119 = {
id = 97017008427632119;
name = "Dario Weclipse";
username = tarzan;
};
}
I'm sorting these objects based on the name, if they don't have a name, i will use the username. To do that, i create a new NSDictionary with the name and id and at the end of the method i sort them by name. The code to sort them is the following:
- (NSArray*)orderFriends
{
NSMutableDictionary* newFriendsDict = [[NSMutableDictionary alloc] init];
for (int i=0; i<[allFriends count];i++)
{
NSMutableDictionary* friendsDict = [[NSMutableDictionary alloc] init];
NSDictionary* friend = [allFriends objectForKey:[NSString stringWithFormat:#"%#", [sortedKeysFriends objectAtIndex:i]]];
if ([[friend objectForKey:#"name"] length] != 0)
{
[friendsDict setObject:[friend objectForKey:#"id"] forKey:#"id"];
[friendsDict setObject:[NSString stringWithFormat:#"%#", [friend objectForKey:#"name"]] forKey:#"name"];
}
else
{
[friendsDict setObject:[friend objectForKey:#"id"] forKey:#"id"];
[friendsDict setObject:[NSString stringWithFormat:#"%#", [friend objectForKey:#"username"]] forKey:#"name"];
}
[newFriendsDict setObject:friendsDict forKey:[NSNumber numberWithInt:i]];
}
NSArray* sp = nil;
sp = [[newFriendsDict allValues] sortedArrayUsingComparator:^(id obj1, id obj2){
NSString *one = [NSString stringWithFormat:#"%#", [obj1 objectForKey:#"name"]];
NSString *two = [NSString stringWithFormat:#"%#", [obj2 objectForKey:#"name"]];
return [one compare:two];
}];
return sp;
}
The problem is that the end result is wrong:
(lldb) po sp
<__NSArrayI 0x160491a0>(
{
id = 93374822540641772;
name = "Alan Weclipse";
},
{
id = 97017008427632119;
name = "Dario Weclipse";
},
{
id = 96553685978449395;
name = "Monica Weclipse";
},
{
id = 96556113096345076;
name = Xavier;
},
{
id = 71685207018702188;
name = "mikeziri ";
},
)
Case sensitive. make all string small or big.
You could also just change
return [one compare:two];
to
return [one compare:two options: options:NSCaseInsensitiveSearch];
Than it will be ordered alphabetically, no matter if upper or lower case...
Several things: There is no reason to build different dictionaries in order to sort, and good reason NOT to do so.
You already found the method sortedArrayUsingComparator. That takes a block that is used to compare pairs of objects, and returns a sorted array. You can use that method to implement any sorting criteria you want.
I would suggest writing a comparator block that compares the name properties of your objects unless it's blank, and uses username if that's blank. It would only be a few lines of code:
NSArray *sortedFriends = [[allFriends allValues] sortedArrayUsingComparator:
^(NSDictionary *obj1, NSDictionary *obj2)
{
NSString* key1 = obj1[#"name"] ? obj1[#"name"] : obj1[#"username"];
NSString* key2 = obj2[#"name"] ? obj2[#"name"] : obj2[#"username"];
return [key1 caseInsensitiveCompare: key2];
}];
EDIT: I just noticed (from your edit of my post) that you are starting from a dictionary, not an array. So what you want to do is to create a sorted array of all the values in the dictionary? Is it acceptable to discard the keys for all the items in your dictionary, and end up with a sorted array of the values?
The other thing you could do would be to build an array of the dictionary keys, sorted based on your sort criteria. Then you could use the array of keys to fetch the items from your dictionary in sorted order.

NSDictionary with ordered keys
(9 answers)
Closed 8 years ago.
I saw many examples on SO but I'm not sure if it applies to this situation. Everywhere it says NSMutableDictionries are not guaranteed an order...but I'm getting my data from the server...so my NSMuteDic looks like this:
{
joe = (
{
fromName = joe;
id = 25;
theMessage = "this is going to be a really big message...";
timeAdded = "2014-04-07 21:08:12";
toName = "me";
},
{
fromName = joe;
id = 10;
theMessage = "why???";
timeAdded = "2014-04-05 20:10:04";
toName = "me";
}
);
bob = (
{
fromName = "me";
id = 24;
theMessage = "blah blah";
timeAdded = "2014-04-06 21:15:06";
toName = bob;
},
{
fromName = bob;
id = 22;
theMessage = message;
timeAdded = "2014-04-06 20:11:57";
toName = "me";
}
);
//more entries here
}
What I want to do is change the order...put bob first and joe second. Is this really impossible to do? I saw many very complex solutions...there's no easy way to do this with just a for loop?
cellForRowAtIndexPath:
NSMutableArray *temp = [myDict objectForKey:keys[indexPath.row]];
cell.Message.text = [[reverse lastObject] valueForKey:#"theMessage"];
cell.dateTime.text = [[reverse lastObject] valueForKey:#"timeAdded"];
return cell;
This is how I'm using it...and when a row is selected I pass the array to the next view controller. The reason why I want to reorder is if a new message will be inserted in the pushed view controller, I want that dictionary to be first in the list so the root view controller can be reordered.
NSArray *keys = [myDict allKeys];
[myDict removeObjectForKey:to];
NSMutableDictionary *temp = [NSMutableDictionary dictionaryWithCapacity:[myDict.count];
temp = myDict;
[myDict removeAllObjects];
[myDict setObject:currentDict forKey:to];
for (int i=0; i<temp.count; i++) {
[myDict setObject:[temp valueForKey:keys[i]] forKey:keys[i]];
}
That's not working because it looks like since myDict is a NSObject, temp gets changed every time myDict changes...from the looks of it the logic should work but it isn't...
NSMutableDictionary is not ordered. There is nothing you can do to guarantee the order of keys because NSDictionary makes no attempt to preserve any particular ordering. To go over a dictionary in a particular order, you have to make an array of the keys that is in the order you want, then iterate that and fetch the corresponding values.
// Get the keys
NSArray *keys = [myDict allKeys];
// Sort the keys
NSArray *sortedArray = [NSArray arrayWithArray:[keys sortedArrayUsingComparator:^(NSString* a, NSString* b) {
return [a compare:b];
}]];
// Iterate the dictionary
for (NSUInteger n = 0 ; < [sortedArray count]; n++) {
id value = [myDict objectForKey:[sortedArray objectAtIndex:n]];
}
I have array of dictionary that needs to be grouped according to PO which is part of the element and also get the total of quantityOrdered according to the same PO.
The PO is dynamic it means it can be any value that needs to be filtered and compute the quantityOrderd accordingly.
Please help.
{
PO = PO2;
QuantityReceived = 1;
},
{
PO = PO1;
QuantityReceived = 3;
},
{
PO = PO1;
QuantityReceived = 3;
},
{
PO = PO3;
QuantityReceived = 2;
},
{
PO = PO2;
QuantityReceived = 2;
},
{
PO = PO3;
QuantityReceived = 4;
},
{
PO = PO1;
QuantityReceived = 1;
},
Apology for the confusion or incomplete question but i need to create a new array of dictionary with similar like this :
{
PO = PO1;
TotalQuanityReceived=7;
LineItems=3;
},
{
PO = PO2;
TotalQuanityReceived=3;
LineItems=2;
},
{
PO = PO3;
TotalQuanityReceived=6;
LineItems=2;
},
i updated my example and make it easy to read.
- (NSArray *)whatever:(NSArray *)dictionaries
{
NSMutableArray *results = [[NSMutableArray alloc] init];
NSMutableDictionary *resultsByPO = [[NSMutableDictionary alloc] init];
for (NSDictionary *dictionary in dictionaries) {
id po = [dictionary objectForKey:#"PO"];
NSMutableDictionary *result = [resultsByPO objectForKey:po];
if (result == nil) {
result = [[NSMutableDictionary alloc] init];
[resultsByPO setObject:result forKey:po];
[results addObject:result];
[result setObject:po forKey:#"PO"];
}
double total = [[result objectForKey:#"TotalQuantityReceived"] doubleValue];
total += [[dictionary objectForKey:#"QuantityOrdered"] doubleValue];
int count = 1 + [[result objectForKey:#"Count"] intValue];
[result setObject:#(total) forKey:#"TotalQuantityReceived"];
[result setObject:#(count) forKey:#"Count"];
}
return results;
}
More pain will come with PO values not conforming to NSCopying.
You can do it the clever way with KVC or the stupid easy way. Let's do it the stupid easy way!
Make an empty NSMutableDictionary. Let's call it dict.
Cycle through your array of dictionaries. For each dictionary:
Fetch its PO. Call that value thisPO.
Fetch dict[thisPO]. Was it nil?
a. Yes. Okay, so this particular PO has not yet been encountered. Set dict[thisPO] to this dictionary's quantity received (as an NSNumber).
b. No. Turn that value into an integer, add this dictionary's quantity received, and set the total back into dict[thisPO] (as an NSNumber).
Done! The result is not quite what you asked for; the result looks like this:
{
PO1 = 100;
PO2 = 120;
...
}
But now, you see, the work of totalling is done and it is easy to transform that into an array of dictionaries if that is what you want.
Not 100% sure if this is what you are saying or not, but to sort an array of dictionaries based on one of the elements it would look something like this.
NSDictionary *d1 = [[NSDictionary alloc] initWithObjectsAndKeys:
[NSNumber numberWithDouble:100],#"PO",
[NSNumber numberWithDouble:0], #"Category",
nil];
NSDictionary *d2 = [[NSDictionary alloc] initWithObjectsAndKeys:
[NSNumber numberWithDouble:50],#"PO",
[NSNumber numberWithDouble:90], #"Category",
nil];
NSArray *unsorted = #[d1, d2];
NSArray *sortedArray;
sortedArray = [unsorted sortedArrayUsingComparator:^NSComparisonResult(id a, id b) {
NSDictionary *first = (NSDictionary*)a;
NSDictionary *second = (NSDictionary*)b;
NSNumber *firstPO = [first objectForKey:#"PO"];
NSNumber *secondPO = [second objectForKey:#"PO"];
return [firstPO compare:secondPO];
}];
NSLog(#"unsorted = %#", unsorted);
NSLog(#"sorted = %#", sortedArray);
I wasn't really sure what PO was, so I just used an NSNumber as an example. Look at this page for an overview of how you would compare a customer object. http://nshipster.com/nssortdescriptor/.
Then you can loop through the array, now in the correct order and build your next NSDictionary.
