I have
NSDictionary *dictionary =
{"aps":
{"alert":"This is a Push Message sent from Server!",
"badge":60
}
}
I have only 1 question
I need 60 from this NSDictionary into NString.
You can just get the NSNumber and format it as a string, something along the lines of:
NSDictionary *aps = [dictionary objectForKey:#"aps"];
NSNumber *num = [aps objectForKey:#"badge"];
NSString *numStr = [num stringValue];

i am making dictionary with 2 array one for keys(ids that you can see in Dic) and one for values(Birth dates that you can see in Dic) my dictionary look like this
100000297621293 = "08/31/1990";
100001904155266 = "12/30/1990";
100003248631105 = "05/27/1990";
100004327360299 = "01/01/1927";
100000157646688 = "08/22/1989";
100001069796883 = "12/03/1989";
100001475514001 = "03/09/1990";
100000717474427 = "08/05/1990";
100001221367192 = "08/05/1990";
100002586744158 = "04/15/1983";
this is just sample dic not full
then after i have another array with ids and im using that array for fetching birth dates from this Dic but i get null values plz help me my code is as below
NOTE: ARRAY WHICH I AM USING FOR KEY, ALWAYS EXIST AS KEY IN DIC
NSDictionary *birthdayDictionary =
[[NSDictionary alloc] initWithObjects:_parssedArrayOfFaceBook forKeys:_parssedArrayOfFaceBookUid];
NSLog(#"asdas%#",birthdayDictionary.description);
NSMutableArray *matches = [NSMutableArray array];
for (NSString *key in _selecteduid) {
NSLog(#" see it%#",key);
NSString *selectedBirthDate = [birthdayDictionary objectForKey:key];
NSLog(#" matched%#",selectedBirthDate);
[matches addObject:selectedBirthDate];
NSLog(#" matched%#",matches);
}
Why is *selectedBirthDate an NSMutableArray? The birth dates (values) are strings! not arrays!
NSString *selectedBirthDate = [birthdayDictionary objectForKey:key];
Assuming selecteduid is a retained property and it has values in it, this code would work fine.
NSDictionary *birthdayDictionary = [NSDictionary dictionaryWithObjects:self.parssedArrayOfFaceBook
forKeys:self.parssedArrayOfFaceBookUid];
NSMutableArray *matches = [#[] mutableCopy];
for (NSString *key in self.selecteduid){
NSString *selectedBirthDate = birthdayDictionary[key];
[matches addObject:selectedBirthDate];
}
I want to add names in a data array only if the name does not previously exist in the data array. When I attempt to print these names, I do get repetitions. Is there a way to solve this?
-(NSMutableArray *)autoComplete
{
NSMutableArray *dataArray = [[NSMutableArray alloc] init];
NSString *url = [NSString stringWithFormat:#"%#45.25,-95.25&limit=100&client_id=Von0J4Bu6INiez5bGby2R&client_secret=50sUjSbg7dba8cQgtpdfr5Ns7wyYTqtmKpUU3khQ",kWSURL];
NSDictionary * returnDict = (NSDictionary *) [self callWebService:url];
if([returnDict objectForKey:#"success"])
{
NSArray *responceArray = [returnDict objectForKey:#"response"];
for (NSDictionary *dict in responceArray) {
placeDC *place = [[placeDC alloc]init];
NSDictionary *placeDict = (NSDictionary *)[dict objectForKey:#"place" ];
NSDictionary *loctionDict =(NSDictionary *)[dict objectForKey:#"loc"];
NSString * name =[placeDict objectForKey:#"name"];
NSString * stateFull =[placeDict objectForKey:#"stateFull"];
NSString * countryFull =[placeDict objectForKey:#"countryFull"];
NSString *latitude =[loctionDict objectForKey:#"lat"];
NSString *longitude = [loctionDict objectForKey:#"long"];
place.placeNmae=name;
place.countryFullName=countryFull;
place.stateFullName=stateFull;
NSLog(#"%# ",stateFull);
place.latitude=[latitude doubleValue];
place.longitude=[longitude doubleValue];
[dataArray addObject:place];
}
}
return dataArray;
}
First Check that is there any response from the Server side or not, to check response use NSLog() or Break Points.
if response is ok then put a the following check your code
if (![dataArray containsObject:#"Some Name"])
{
// add Object
}
You could add the name NSString to an NSSet and check in every cycle whether it contains it or not.
Inside your if you could write something like:
NSArray *responceArray = [returnDict objectForKey:#"response"];
NSSet *names = [[NSSet alloc] init];
for (NSDictionary *dict in responceArray) {
NSDictionary *placeDict = (NSDictionary *)[dict objectForKey:#"place" ];
NSString * name =[placeDict objectForKey:#"name"];
if (![names containsObject:name]) {
[names addObject:name];
placeDC *place = [[placeDC alloc]init];
NSDictionary *loctionDict =(NSDictionary *)[dict objectForKey:#"loc"];
NSString * stateFull =[placeDict objectForKey:#"stateFull"];
NSString * countryFull =[placeDict objectForKey:#"countryFull"];
NSString *latitude =[loctionDict objectForKey:#"lat"];
NSString *longitude = [loctionDict objectForKey:#"long"];
place.placeNmae=name;
place.countryFullName=countryFull;
place.stateFullName=stateFull;
NSLog(#"%# ",stateFull);
place.latitude=[latitude doubleValue];
place.longitude=[longitude doubleValue];
[dataArray addObject:place];
}
}
Hope this helps!
Do one thing, add your dict in another array and search in this array that data already exist or not,
[tempAry addObject: dict];
and before insertion
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"name == %#", name];
NSArray *filteredArray = [tempAry filteredArrayUsingPredicate:predicate];
if ([filteredArray count] == 0)
{
[dataArray addObject:place];
}
else{
//Already exist
}
Why don't you create a separate dictionary, as an ivar or property of you class, for storing our required value, say it as :
NSMutableDictionary *uniqueValueDict=[NSMutableDictionary new];
And keep storing your required value and key as:
[uniqueValueDict setObject:stateFull forKey:uniqueValueDict];
Your work will be done.
This is the easiest solution that i have applied and this should get you going in picking up unique elements out of array.
NSArray * claimedOfferArray = [[NSArray alloc]initWithObjects:#"A",#"B",#"A",#"C",#"B" nil];
NSArray * distinctArray = [[NSArray alloc]init];
distinctArray =[[NSSet setWithArray:claimedOfferArray] allObjects];
This code will also work with NSMutableArray
Let me know if it works for you..:).
I have an NSMutableArray that looks like this
{
"#active" = false;
"#name" = NAME1;
},
{
"#active" = false;
"#name" = NAME2;
}
Is there a way to convert this to an NSDictionary and then use objectForKey to get an array of the name objects? How else can I get these objects?
There is a even shorter form then this proposed by Hubert
NSArray *allNames = [array valueForKey:#"name"];
valueForKey: on NSArray returns a new array by sending valueForKey:givenKey to all it elements.
From the docs:
valueForKey:
Returns an array containing the results of invoking
valueForKey: using key on each of the array's objects.
- (id)valueForKey:(NSString *)key
Parameters
key The key to retrieve.
Return Value
The value of the retrieved key.
Discussion
The returned array contains NSNull elements for each object that returns nil.
Example:
NSArray *array = #[#{ #"active": #NO,#"name": #"Alice"},
#{ #"active": #NO,#"name": #"Bob"}];
NSLog(#"%#\n%#", array, [array valueForKey:#"name"]);
result:
(
{
active = 0;
name = Alice;
},
{
active = 0;
name = Bob;
}
)
(
Alice,
Bob
)
If you want to convert NSMutableArray to corresponding NSDictionary, just simply use mutableCopy
NSMutableArray *phone_list; //your Array
NSDictionary *dictionary = [[NSDictionary alloc] init];
dictionary = [phone_list mutableCopy];
This is an Array of Dictionary objects, so to get the values you would:
[[myArray objectAtIndex:0]valueForKey:#"name"]; //Replace index with the index you want and/or the key.
This is example one of the exmple get the emplyee list NSMutableArray and create NSMutableDictionary.......
NSMutableArray *emloyees = [[NSMutableArray alloc]initWithObjects:#"saman",#"Ruchira",#"Rukshan",#"ishan",#"Harsha",#"Ghihan",#"Lakmali",#"Dasuni", nil];
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
for (NSString *word in emloyees) {
NSString *firstLetter = [[word substringToIndex:1] uppercaseString];
letterList = [dict objectForKey:firstLetter];
if (!letterList) {
letterList = [NSMutableArray array];
[dict setObject:letterList forKey:firstLetter];
}
[letterList addObject:word];
} NSLog(#"dic %#",dict);
yes you can
see this example:
NSDictionary *responseDictionary = [[request responseString] JSONValue];
NSMutableArray *dict = [responseDictionary objectForKey:#"data"];
NSDictionary *entry = [dict objectAtIndex:0];
NSString *num = [entry objectForKey:#"num"];
NSString *name = [entry objectForKey:#"name"];
NSString *score = [entry objectForKey:#"score"];
im sorry if i can't elaborate much because i am also working on something
but i hope that can help you. :)
No, guys.... the problem is that you are stepping on the KeyValue Mechanism in cocoa.
KeyValueCoding specifies that the #count symbol can be used in a keyPath....
myArray.#count
SOOOOOO.... just switch to the ObjectForKey and your ok!
NSMutableDictionary *myDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:#"theValue", #"#name", nil];
id kvoReturnedObject = [myDictionary valueForKey:#"#name"]; //WON'T WORK, the # symbol is special in the valueForKey
id dictionaryReturnedObject = [myDictionary objectForKey:#"#name"];
NSLog(#"object = %#", dictionaryReturnedObject);
I'm working with JSON library and see this situation:
Convert JSON string to NSDictionary
Scenario 1:
NSString *jsonString = #"{\"Name\":\"Foo\", Points:5}";
NSDictionary *dictionary = (NSDictionary*)[jsonParser objectWithString:jsonString];
NSLog(#"Dictionary: %#",dictionary);
I see the result as followed:
Dictionary: {
Name = "Foo";
Points = 5;
}
So that's correct.
Scenario 2:
NSString *jsonString = #"{\"Name\":\"Foo\", Points:0.5}";
NSDictionary *dictionary = (NSDictionary*)[jsonParser objectWithString:jsonString];
NSLog(#"Dictionary: %#",dictionary);
I see the result as followed:
Dictionary: {
Name = "Foo";
Points = "0.5";
}
???
Scenario 3:
NSString *jsonString = #"{\"Name\":\"Foo\", Points:-1}";
NSDictionary *dictionary = (NSDictionary*)[jsonParser objectWithString:jsonString];
NSLog(#"Dictionary: %#",dictionary);
I see the result as followed:
Dictionary: {
Name = "Foo";
Points = "-1";
}
???
Why does the JSON library convert the negative numbers or number less than 1 into string?
Do you know how to prevent this from happening?
I do not have the "why", but it may not be an issue for you since you can call for the intValue or floatValue when retrieving.
NSLog(#"Points = %.2f", [[dictionary valueForKey:#"Points"] floatValue]);
I'm trying to pull two values from this Dictionary, But the values I'm getting have "()" around them. Any Ideas what is causing this?
Here is the ServerOutput:
{"Rows":[{"userid":"1","location":"beach"}]}
Dictionary after JSON:
{
Rows = (
{
location = beach;
userid = 1;
}
);
}
This is what I'm getting:
location : (
beach
)
user Id : (
1
)
Both the userid and the location key values have the "()". Here is the code. Thanks a lot.
NSString *serverOutput= [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];
if(serverOutput > 1){
SBJSON *jsonFF = [[SBJSON new] autorelease];
NSError *error3 = nil;
NSDictionary *useridDict= [jsonFF objectWithString:serverOutput error:&error3];
NSLog(#"useridDict: %#",useridDict);
idreturn = [[useridDict valueForKey:#"Rows"] valueForKey:#"userid"];
locationreturn = [[useridDict valueForKey:#"Rows"] valueForKey:#"location"];
NSLog(#" user Id : %#", idreturn);
NSLog(#" location : %#", locationreturn);
Just to clarify what is going on. When parsing JSON {} gets returned as a dictionary and [] gets retured as an array. So we have useridDict an NSDictionary containing the parsed data.
'useridDict' has one key Rows which returns an NSArray.
NSArray *useridArray = [useridDict objectForKey:#"Rows"];
Our useridArray has one element, an NSDictionary
NSDictionary *dict = [useridArray objectAtIndex:0];
This dict contains the two keys: location and userid
NSString *location = [dict objectForKey:#"location"];
NSInteger userid = [[dict objectForKey:#"userid"] intValue];
You can use like this.
idreturn = [[[useridDict valueForKey:#"Rows"] objectAtIndex:0]valueForKey:#"userid"];
locationreturn = [[[useridDict valueForKey:#"Rows"] objectAtIndex:0] valueForKey:#"location"];
