Sections = (
{
EnglishName = whatsnew;
ID = 1;
Name = "What's New";
ParentSectionID = 0;
}
this is the dictionary i want to acces Name of can i access it.
From OP comment, here is the way to obtain name value in the NSMutableDictionary :
( assume your NSMutableDictionary is named as Sections ):
NSString *name = (NSString *)[Sections objectForKey:#"Name"];

Response array like this
NewDataSet = {
Table = (
{
City = {
text = "\nThiruvananthapuram";
};
Country = {
text = "\n\nIndia";
};
text = "\n";
},
{
City = {
text = "\nVellore";
};
Country = {
text = "\n\nIndia";
};
text = "\n";
}
);
text = "\n";
I have write this code..
xmlDictionary = [XMLReader dictionaryForXMLString:xmlResultString error:nil];
NSLog(#"%#",xmlDictionary);
NSLog(#"%#",xmlDictionary);
NSArray * responseArr = xmlDictionary[#"NewDataSet"];
NSLog(#"%#",responseArr);
for(NSDictionary * dic in responseArr)
{
NSLog(#"%#",dic);
//[array1 addObject:[dic valueForKey:#"City"]];
[array1 addObject:[[dic valueForKey:#"City"] valueForKey:#"text"]];
}
but not get the data. in array1. please help me out this thanks in advance.
Problem is i will not get the value in NSDictionary.
Error log is
this class is not key value coding-compliant for the key City.'
I got my Solution problem is i will not get the direct City key. Because City key is under the NewDataSet & Table
so first you go to the NewDataSet and then Table key then finally you get the City key.
Now get array data from Dictionary Like
NSArray * City=[[NSArray alloc]init];
City=[[[xmlDictionary valueForKey:#"NewDataSet"] valueForKey:#"Table"] valueForKey:#"City"];
NSLog(#"%#",City);
pass multiple keys inside key this is the solution.
It seems you haven't allocated array1 anywhere,
Your solution goes here:
array1 = [[NSMutableArray alloc]init];
for(NSDictionary * dic in responseArr)
{
[array1 addObject:[dic valueForKey:#"City"]];
}
NSLog(#"array1 >> %#",array1);
If you have already allocated array1, then please try to log the value for [dic valueForKey:#"City"].
try this code...
for(int i =0;i<[responseArr count];i++)
{
NSString *str = [[responseArr objectAtIndex:i] valueForKey:#"City"];
[array1 addObject:str];
}
let me know it is working or not!!!
Happy Coding!!!
array1 = [[NSMutableArray alloc]init];
for(NSDictionary * dic in responseArr)
{
[array1 addObject:[dic objectForKey:#"City"]];
}
NSLog(#"array1 >> %#",array1);
Try this
In my application ,the dictionary value contains following content.How to retrieve the each and store it new array

}
For ex: checka0-checka14 in one array, Here the problem is checka2 and checka6 is not available, Im new bee in xcode,Please help me to retrieve
Your question is not clear. Possibly you need to get all keys in your dictionary and separating each item with specific word in it(checka/checkb/checkc).
If that is the case then,
You will get all the keys using:
NSArray *dictKeys = [yourDictionary allKeys];
You can implement this in multiple ways, one of them:
For storing it in same array:
for (NSString *key in [yourDictionary allKeys])
{
[yourArray addObject:[yourDictionary objectForKey:key]];
}
For storing it in seperate arrays:
for (NSString *key in [yourDictionary allKeys])
{
if([key rangeOfString:#"checka"].location != NSNotFound)
{
//add checka to first array
[yourFirstArray addObject:[yourDictionary objectForKey:key]];
}
else if([key rangeOfString:#"checkb"].location != NSNotFound)
{
//add checkb to second array
[yourSecondArray addObject:[yourDictionary objectForKey:key]];
}
...
}
if contryArray is your dictionary then access it as follow
[contryArray valueForKey:#"checka0"];
and go on adding this values to another array
You can use the following code:
- (void)filterDictionary:(NSDictionary *)dict
{
NSArray *allKeys = [dict allKeys];
NSMutableArray *allValues = [[NSMutableArray alloc]init];
for(id key in allKeys)
{
id value = [dict valueForKey:key];
[allValues addObject:[value stringValue]];
}
}
I have an application in which i am having the details of the members as a dictionary.i want to add an array with particular object from the dictionary.The response i am having is like this,
{
500 = {
name = baddd;
status = "<null>";
};
511 = {
name = abyj;
status = "Hi all...:-)";
};
512 = {
name = abyk;
status = fdffd;
};
}
I want to create an array with the results of name only.i have tried like this
for(int i=0;i<=self.currentChannel.memberCount;i++)
{
NSString *name=[NSString stringWithFormat:#"%#",[self.currentChannel.members objectForKey:#"name"]] ;
NSLog(#"%#",name);
[searchfriendarray addObject:name];
}
NSLog(#"%#",searchfriendarray);
but the value added is null. can anybody help me ?
Traverse objectEnumerator to get the values (inner dictionaries). Then just add the value of "name" to the resulting array. Example (assuming the dictionary is named d):
NSDictionary* d = ...
NSMutableArray* array = [NSMutableArray arrayWithCapacity:d.count];
for(NSDictionary* member in d.objectEnumerator) {
[array addObject:[member objectForKey:#"name"]];
}
Krumelur was faster than me ;) He is right by saing that you should traverse the dictionary values first. In your implementation you don't reference your counter variable i somewhere, so the NSString name is the same in each iteration.
This may help you..
// here you can get Array of Dictionary First
NSArray *arr = [[NSArray alloc] initWithContentsOfFile:#""]; // get array first from your response
NSDictionary *temp = [[NSDictionary alloc] initWithDictionary:self.currentChannel.members];
for(int i=0;i<=self.currentChannel.memberCount;i++)
{
NSDictionary *temp = [arr objectAtIndex:i];
NSString *name=[NSString stringWithFormat:#"%#",[temp objectForKey:#"name"]] ;
NSLog(#"%#",name);
[searchfriendarray addObject:name];
}
NSLog(#"%#",searchfriendarray);
Thanks.
I am trying to read the following json object using the json-framework and obj-C
{
Sections = {
Now = "Wednesday 9 February 2011 02:40";
Section = (
{
Article = (
{
Exceprt = "text here";
ID = 49011;
Title = "text here";
Type = Politics;
audioCounter = 0;
commentsCounter = 0;
hasMore = false;
important = False;

photoCounter = 0;
time = "21:12";
timeStamp = "2/8/2011 9:14:16 PM";
timeStatus = True;
videoCounter = 0;
viewsCounter = 0;
},
{

ID = 49010;
Title = "text here";
Type = Politics;
audioCounter = 0;
commentsCounter = 0;
hasMore = false;

viewsCounter = 0;
}
);
ID = 22;
Name = "EN Live";
totalNews = 3416;
}
);
};
}
My intent is to have a list of the articles (list of dictionaries) so that I can later access them easily. I have been stuck a while on this and my code is giving me an error about calling a non existent method for NSArray which has led me to suspect that I am misunderstanding the json object. I am totally new to this and any help is greatly appreciated.
Here's my code:
NSDictionary *results = [jsonString JSONValue];
NSDictionary *Articles = [[results objectForKey:#"Sections"] objectForKey:#"Section"];
NSArray *ListOfArticles = [Articles objectForKey:#"Article"];
for (NSDictionary *article in ListOfArticles)
{
NSString *title = [article objectForKey:#"Title"];
NSLog(title);
}
Thanks !
First of all, those aren’t valid JSON data. Names (in name/value pairs) are strings and must be quoted. String values must always be quoted. Boolean values must be either true or false (lowercase). Check http://json.org/ and http://www.ietf.org/rfc/rfc4627.txt?number=4627 and http://jsonlint.com
Here’s the structure of your data:
The top level value is an object (dictionary)
This object has a name (key) called Sections whose value is itself another object (dictionary)
Sections has a name (key) called Section whose value is an array
Each element in the Section array is an object (dictionary)
Each element in the Section array has a name (key) called Article whose value is an array, as well as other names (keys): ID, title, totalNews
Each element in the Article array is an object
If your JSON data were valid, you could parse them as follows:
// 1.
NSDictionary *results = [jsonString JSONValue];
// 2.
NSDictionary *sections = [results objectForKey:#"Sections"];
// 3.
NSArray *sectionsArray = [sections objectForKey:#"Section"];
// 4.
for (NSDictionary *section in sectionsArray) {
// 5.
NSLog(#"Section ID = %#", [section objectForKey:#"ID"];
NSLog(#"Section Title = %#", [section objectForKey:#"Title"];
NSArray *articles = [section objectForKey:#"Article"];
// 6.
for (NSDictionary *article in articles) {
NSLog(#"Article ID = %#", [article objectForKey:#"ID"];
NSLog(#"Article Title = %#", [article objectForKey:#"Title"];
// …
}
}
Your JSON framework is probably parsing out an NSDictionary where you're expecting an NSArray. It'll let you assign an NSDictionary to an NSArray, but then you'll get a runtime exception when you attempt to call a method on your "array". Judging by the JSON you posted (which isn't correct JSON), this is what I would have my parsing code look like. The names of the NSDictionaries and NSArrays are simply named after the JSON attributes they represent.
NSDictionary* results = [jsonString JSONValue];
NSDictionary* sections = [results valueForKey:#"Sections"];
NSArray* section = [sections valueForKey:#"Section"];
NSArray article = [[section objectAtIndex:0] valueForKey:#"Article"];
for (NSDictionary* anArticle in article) {
NSLog(#"%#", [anArticle valueForKey:#"Title"]);
}
In my current iPhone project, I have a created a dictionary that groups the sub dictionaries by the first letter of the "Name" key. NSLog returns the following. I would like to create an identical dictionary that only shows the "Name" key under each initial letter key. What is the best way for making a copy of some of the items in the sub dictionaries? The ObjectForKey methods will select only the items for the initial letter (ex: "B" or "C"). Please let me know if I didn't explain this clearly enough.
Thanks!
sectionedDictionaryByFirstLetter:{
B = (
{
Name = "B...A Name Starting with B";
Image = "ImageName1.png";
Text = "Some Text";
}
);
C = (
{
Name = "C...A Name Starting with C";
Image = "ImageName2.png";
Text = "Some Text";
}
);
N = (
{
Name = "N...A Name Starting with N";
Image = "ImageName3.png";
Text = "Some Text";
},
{
Name = "N...A Name Starting with N";
Image = "ImageName4.png";
Text = "Some Text";
},
{
Name = "N...A Name Starting with N";
Image = "ImageName5.png";
Text = "Some Text";
}
);
}
The final result I'm looking for is:
sectionedDictionaryByFirstLetter:{
B = (
{
Name = "B...A Name Starting with B";
}
);
C = (
{
Name = "C...A Name Starting with C";
}
);
N = (
{
Name = "N...A Name Starting with N";
},
{
Name = "N...A Name Starting with N";
},
{
Name = "N...A Name Starting with N";
}
);
}
Core Foundation has a great function, CFDictionaryApplyFunction (I wish they ported its functionality to NSDictionary too). However, NSDictionary and CFDictionary are "toll-free bridges", meaning that you can cast between them at no cost.
So, the solution would be to create an applier function, SaveName, which would be used in the CFDictionaryApplyFunction above. Example:
void SaveName(const void* key, const void* value, void* context) {
NSMutableDictionary* result = (NSMutableDictionary*) context;
NSDictionary* dataDict = (NSDictionary*) value;
NSString* letterKey = (NSString*) key;
[result setObject:[dataDict valueForKey:#"Name"] forKey:#letterKey];
}
void main() {
NSDictionary* exampleDict = .. ;
NSMutableDictionary* resultDict = [NSMutableDictionary dictionary];
CFDictionaryApplyFunction((CFDictionaryRef)exampleDict, SaveName, (void*)resultDict);
// now, the resultDict contains key-value pairs of letter-name!
}
My code assumes that there is only one object in the "value" dictionary. You can change SaveName to take into consideration your own data structure, but that's basically the way to do it.
NSMutableDictionary* newDict = [NSMutableDictionary dictionary];
for (NSString* key in sectionedDictionaryByFirstLetter) {
NSMutableArray* newList = [NSMutableArray array];
[newDict setObject:newList forKey:key];
for (NSDictionary* entry in [sectionedDictionaryByFirstLetter objectForKey:key]) {
NSString* name = [entry objectForKey:#"Name"];
[newList addObject:[NSDictionray dictionaryWithObject:name forKey:#"Name"]];
}
}
