this is the print screen of nsmutablearray.
this 2409,2410,2412 is not fix key. it coming dynamically.
{
2409 = (
{
AltSelectionPrice = "2.00";
},
{
AltSelectionPrice = "3.00";
}
);
2410 = (
{
AltSelectionPrice = "7.00";
},
{
AltSelectionPrice = "0.00";
}
);
2412 = (
{
AltSelectionPrice = "0.00";
},
{
AltSelectionPrice = "9.00";
},
{
AltSelectionPrice = "5.00";
}
);
}
thnx in advance.
I am currently on my work computer which runs Windows so cannot post exact code. But what you need to do is get hold of dictionary in the array. May be like following:
NSDictionary* dict = [myMutableArray objectAtIndex:0];
and then iterate over keys in the dictionary:
for (id key in [dict keyEnumerator]) {
//use the key or get the object of that key using [dict objectForKey:key]
}
Update: I assumed you are getting this array from a JSON parser!

I have one more big problem while parse the values from Webservice response. I dont know the key for the values in the webservice response. For example,
class = (
{
"ObjectiveC" =
(
{
"brief_desc" = "ObjectiveC";
date = "2008-02-27";
"event_status" = Attended;
},
{
"brief_desc" = "ObjectiveC";
date = "2008-03-05";
"event_status" = Attended;
},
{
"brief_desc" = "ObjectiveC";
date = "2008-03-12";
"event_status" = Missed;
},
);
},
{
"Java" = (
{
"brief_desc" = "Java";
date = "2008-02-27";
"event_status" = Attended;
},
{
"brief_desc" = "Java";
date = "2008-03-05";
"event_status" = Attended;
},
{
"brief_desc" = "Java";
date = "2008-03-12";
"event_status" = Missed;
},
);
}
);
In this response even we dont know the keys "ObjectiveC" and "Java". The keys("ObjectiveC and Java") should be change in every response retured. How to get values of key (Unknown key)? How can i parse this response and get the values?
I would enumerate through the keys to get the value. Here is an example of enumeration in objective-c.
NSEnumerator *enumerator = [myDictionary keyEnumerator];
id key;
while ((key = [enumerator nextObject])) {
//assuming value will be string
NSString *valueForKey = [myDictionary valueForKey:key];
//assuming value is another dictionary
NSDictionary *subDictionary = [myDictionary objectForKey:key];
}
And if you don't know the keys of the sub dictionaries, you can enumerate through those as well.
NSDictionary has - (NSArray *)allKeys and - (NSArray *)allValues. One of those might help
NSDictionary * lessonDict = [[NSDictionary alloc] initWithObjectsAndKeys:#"Key", #"Value", #"Key 2", #"Value 2", nil];
NSArray *values = [lessonDict allValues];
NSArray *keys = [lessonDict allKeys];
NSLog(#"Keys: %#",keys);
NSLog(#"Values: %#",values);
I'am able to display the data in nsdictionary using this code
NSString *testXMLString = #"<items><item id=\"0001\" type=\"donut\"><name>Cake</name><ppu>0.55</ppu><batters><batter id=\"1001\">Regular</batter><batter id=\"1002\">Chocolate</batter><batter id=\"1003\">Blueberry</batter></batters><topping id=\"5001\">None</topping><topping id=\"5002\">Glazed</topping><topping id=\"5005\">Sugar</topping></item></items>";
NSError *parseError = nil;
NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:testXMLString error:&parseError];
NSLog(#"%#", xmlDictionary);
and the output is
items = {
item = {
batters = {
batter = (
{
id = 1001;
text = Regular;
},
{
id = 1002;
text = Chocolate;
},
{
id = 1003;
text = Blueberry;
}
);
};
id = 0001;
name = {
text = Cake;
};
ppu = {
text = "0.55";
};
topping = (
{
id = 5001;
text = None;
},
{
id = 5002;
text = Glazed;
},
{
id = 5005;
text = Sugar;
}
);
type = donut;
};
}; }
Can anyone please help me how to convert this dictionary into a xml file?
The NSPropertyListSerialization class should be able to do this for you.
Sorry for the long question but that best summarizes what I am trying to do:
My JSON Looks like:
{
4e8cf1d6c7e24c063e000000 = {
"_id" = {
"$id" = 4e8cf1d6c7e24c063e000000;
};
author = faisal;
comments = (
{
author = adias;
comment = amazing;
},
{
author = nike;
comment = "I concur";
}
);
created = {
sec = 1317772800;
usec = 0;
};
text = "This is a random post";
title = "post # 1";
type = (
punjabi
);
};
4e91fd49c7e24cda74000000 = {
"_id" = {
"$id" = 4e91fd49c7e24cda74000000;
};
author = draper;
comments = (
{
author = adias;
comment = "amazing again";
}
);
created = {
sec = 1318118400;
usec = 0;
};
text = "This is a random post again";
title = "post # 2";
type = (
punjabi
);
};
}
What I would like to do is to ultimately have a UTTableview with each row having a title (text from above JSON):
This is the code I have so far:
NSString *responseString = [request responseString];
NSDictionary *resultsDictionary = [responseString objectFromJSONString];
How do I put everything in an array for the UITableView? Again I am just a little rusty as I can swear I have done that before.
If you don't need the keys then you can convert it to an array by using allValues, e.g.:
NSArray *values = [resultsDictionary allValues];
Does your JSON really parse to an NSDictionary, or is this an NSArray containing NSDictionary instances? If the latter, then isn't it just something like:
NSString *textForCell = [[resultsArray objectAtIndex:row] valueForKey:#"title"];
I have the following JSON value:
-(
{ Key = IsEmail;
Value = 1; },
{ Key = TrackingInterval;
Value = 20; },
{ Key = IsBackup;
Value = 1; },
{ Key = WipeOnRestore;
Value = 1; }
)
How might I go about parsing this object into an array or string? - i.e. eack key values to be stored in an array and each Value to be stored in another array.
Please help me out with this.
Thanks :)
This approach uses the json-framework.
I've shortened your example:
NSString *jsonString = #"[{\"Key\":\"IsEmail\",\"Value\":\"1\"},{\"Key\":\"TrackingInterval\",\"Value\":\"20\"},{\"Key\":\"IsBackup\",\"Value\":\"1\"}]";
NSMutableArray *keys = [NSMutableArray array];
NSMutableArray *values = [NSMutableArray array];
NSArray *json = [jsonString JSONValue];
for (NSDictionary *pair in json) {
[keys addObject:[pair objectForKey:#"Key"]];
[values addObject:[pair objectForKey:#"Value"]];
}
NSLog(#"%#", keys);
NSLog(#"%#", values);
Output:
2011-05-18 14:23:55.698 [36736:207] (
IsEmail,
TrackingInterval,
IsBackup
)
2011-05-18 14:23:55.700 [36736:207] (
1,
20,
1
)

Your data is not vald json, You may want to structure it more like this:
var theObj = { IsEmail: 1, TrackingInterval: 20, IsBackup: 1, WipeOnRestore: 1 };
Then you could populate your key and value arrays something like this:
var keys = new Array();
var values = new Array();
for (prop in theObj) {
keys.push(prop);
values.push(theObj[prop]);
}
if the JSON is in below format,
responseString=[ {
Key = IsEmail;
Value = 1;
},
{
Key = TrackingInterval;
Value = 20;
},
{
Key = IsBackup;
Value = 1;
},
{
Key = WipeOnRestore;
Value = 1;
}]
then,
NSArray *resultArray=[responseSrting JSONValue];
NSMuatbleArray *keyArray=[[NSMutableArray alloc] init];
NSMutableArray *valueArray=[[NSMutableArray alloc] init];
for(NSDictionary *dict in resultsArray){
[keyArray addObject:[dict objectForKey:#"Key"]];
[valueArray addObject:[dict objectForKey:#"Value"]];
}
then, all your keys are stored in keyArray and all your values are stored in valueArray
I have a large NSDictionary that I need to loop through and create separate NSArrays. Here are the contents:
(
{
id = {
text = "";
};
sub = {
text = " , ";
};
text = "";
"thumb_url" = {
text = "";
};
title = {
text = "2010-2011";
};
type = {
text = "title";
};
},
{
id = {
text = "76773";
};
sub = {
text = "December 13, 2010";
};
text = "";
"thumb_url" = {
text = "http://www.puc.edu/__data/assets/image/0004/76774/varieties/thumb.jpg";
};
title = {
text = "College Days - Fall 2010";
};
type = {
text = "gallery";
};
},
{
id = {
text = "";
};
sub = {
text = "";
};
text = "";
"thumb_url" = {
text = "";
};
title = {
text = "2009-2010";
};
type = {
text = "title";
};
},
{
id = {
text = "76302";
};
sub = {
text = "December 3, 2010";
};
text = "";
"thumb_url" = {
text = "http://www.puc.edu/__data/assets/image/0019/76303/varieties/thumb.jpg";
};
title = {
text = "Christmas Colloquy";
};
type = {
text = "gallery";
};
}
)
Each section has a type key, which I need to check. When it finds the title key, I need to add those to an array. Then the next sections that would use the gallery key needs to be in its own array until it finds another title key. Then the gallery keys after that into their own array.
I am using a UITableView section titles and content. So, the NSDictionary above should have one NSArray *titles; array, and two other arrays each containing the galleries that came after the title.
I have tried using a for loop but I just can't seem to get it right. Any ideas would be appreciated.
It's somewhat unclear by your log, but I'm guessing your NSDictionary has values of NSDictionary? If so:
NSMutableArray *titles = [NSMutableArray array];
// etc.
for (id key in sourceDictionary) {
NSDictionary *subDictionary = [sourceDictionary objectForKey:key];
if ([subDictionary objectForKey:#"type"] == #"title")
[titles addObject:[subDictionary objectForKey:#"title"]];
// etc.
}
Your question is a bit unclear... but this is how you would properly loop through an NSDictionary.
EDIT:
NSMutableDictionary *galleries = [NSMutableDictionary dictionary];
NSString *currentTitle;
for (id key in sourceDictionary) {
NSDictionary *subDictionary = [sourceDictionary objectForKey:key];
NSString *type = [subDictionary objectForKey:#"type"];
if (type == #"title") {
currentTitle = [subDictionary objectForKey:#"title"];
if ([galleries objectForKey:currentTitle] == nil)
[galleries setObject:[NSMutableArray array] forKey:currentTitle];
} else if (type == #"gallery" && currentTitle != nil)
[[galleries objectForKey:currentTitle] addObject:subDictionary];
}
After this loop, galleries will contain keys of type NSString (with values of the titles), and corresponding objects of type NSArray (with values of the gallery NSDictionarys). Hopefully this is what you were going for.
NSString *key;
for(key in someDictionary){
NSLog(#"Key: %#, Value %#", key, [someDictionary objectForKey: key]);
}
Modern Objective-C syntax:
NSMutableArray *things = [NSMutableArray array];
NSMutableArray *stuff = [NSMutableArray array];
NSMutableArray *bits = [NSMutableArray array];
[dictionaries enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
[things addObject:[obj valueForKeyPath:#"thing"]];
[stuff addObject:[obj valueForKeyPath:#"enclosing_object.stuff"]];
[bits addObject:[obj valueForKeyPath:#"bits"]];
}];
