I have an array called someArray. I would like to access the name value of the NSArray. I'm trying to access it using the following, but with out any luck. How do I do it properly?
cell.textLabel.text = [[someArray objectAtIndex:indexPath.row] objectForKey:#"name"];
some array {
haserror = 0;
headers = {
code = 0;
haserror = 0;
nodeid = "fe1.aaaaaa.2.undefined";
time = 16;
};
results = (
{
coords = (
"44.916667",
"8.616667"
);
id = 2;
key = alessandria;
name = Alessandria;
state = Piemonte;
zip = 1512;
},
{
coords = (
"43.616944",
"13.516667"
);
id = 3;
key = ancona;
name = Ancona;
state = Marche;
zip = 601;
},
}
As far as i see from you data model, the key name is a node under the key results. You can use this data model as a dictionary map, the code snippet below must give you what you need..
NSDictionary *myObject = [[someArray objectAtIndex:indexPath.row] objectForKey:#"results"];
cell.textLabel.text = [myObject objectForKey:"name"];
IMPORTANT NOTE: If you have some lopps or some other mechanisms for receiving data, there may be more efficent ways for your sıolution, so please give some more additional info about what you are exactly tryin to do
As others have noted, someArray is a dictionary while results is a key pointing to an array inside of your dictionary. If you want an array of all of the name fields in your results array, you could use valueForKeyPath: on the someArray variable, like this:
NSArray *names = [someArray valueForKeyPath:#"results.name"];
The names variable should now contain "Alessandria", and "Ancona" from the data set your show in your example code.
I got a NSDictionary that when I do a [currentOrder debugDescription] call on it the layout is below, when I then do a:
[currentOrder valueForKey: #"itemOrder"]
It return it funny with the brackets as:
(
"4 X ESPRESSO"
)
where it should only be (without brackets):
4 X EXPRESSO
Any idea why?
Content of currentOrder:
currentOrder: <__NSArrayM 0x68426c0>(
{
extra1Select = 0;
extra2Select = 0;
extra3Select = 0;
itemCost = 58;
itemOrder = "4 X ESPRESSO";
itemOrderDescription = "Cookie: YES, Sugar: YES";
itemQuantity = 4;
itemRestaurant = VidaECaffe;
plistItem = {
cost = "11.5";
description = "R11.50";
extra1 = {
desc = Cookie;
details = (
{
cost = "3.00";
option1 = YES;
},
{
cost = "0.00";
option2 = NO;
}
);
};
extra2 = {
desc = Sugar;
details = (
{
cost = "0.00";
option1 = YES;
},
{
cost = "0.00";
option2 = NO;
}
);
};
itemRestaurant = VidaECaffe;
level = 1;
title = ESPRESSO;
};
}
)
The problem is that currentOrder is not a dictionary but a NSArray containing a dictionary. The failure you are making next is that you use valueForKey: which is part of the key value coding family and not the designated access method for dictionaries (which is objectForKey:), and the array returns you a filtered array as a result...
When you print out the value of an array or dictionary in the debugger, the debugger includes the extra brackets, braces, and whatnot so you can see the layout of the structure you are asking about.
If the debugger shows the contents of an array something like
(
"Foobar"
)
it's telling you that the array has one element, a string with the value Foobar.
Put entirely another way: Read up on what the debugger does when it prints out values. Lots of resources here and on the web for this. For example: Debugging with GDB: Introduction to Commands, Print and Print-Object
I'm sorry in advance for a newbie question. I've been working on this for days, and I'm having comprehension problems. I used sudzc to help connect to my web service. The example function only returns 1 result (the last one). How can I load all the results into an array so that I can find CSHR_NUM = 8? I'm not sure if there is a problem with:
- (void) GetCashiersHandler: (id) value
Any help would be greatly appreciated!
The sudzc logging returns (there are hundreds of entries, I cut it down):
<TC diffgr:id="TC1" msdata:rowOrder="0">
<CSHR_POS_NAME>JACKSON<CSHR_POS_NAME />
<CSHR_NUM>8</CSHR_NUM>
</TC>
<TC diffgr:id="TC2" msdata:rowOrder="1">
<CSHR_POS_NAME>ALISON</CSHR_POS_NAME>
<CSHR_NUM>464</CSHR_NUM>
</TC>
I use the example method of calling:
[service GetCashiers:self action:#selector(GetCashiersHandler];
// Handle the response from GetCashiers to get login in name.
- (void) GetCashiersHandler: (id) value
{
// Do something with the CXMLNode* result
CXMLNode *result = (CXMLNode*)value;
NSLog(#"I returned the value: %#", result);
}
NSLog Results:
I returned the value: {
GetCashiersResult = {
diffgram = {
NewDataSet = {
TC = {
"CSHR_NUM" = 464;
"CSHR_POS_NAME" = ALLISON;
};
};
};
schema = {
element = {
complexType = {
choice = {
element = {
complexType = {
sequence = {
element = 0;
};
};
};
};
};
};
};
};
}
NSMutableArray * myData = [[NSMutableArray alloc] initWithCapacity:5];
// loop over items to add and add them with
[myData addObject:myItem];
I got a big issue when trying to parse json data in xcode. I have actually tried with two different parser and it still returns me a wrong json. Could anyone help in that ?
The string to parse (called jsonResp) is equal to :
{
"error":false,
"errorMessage":null,
"debugMessage":null,
"count":1,
"list":"links",
"data":[
{
"date":"Jeudi \u00e0 00:00:00",
"type":"friend",
"picture":"http://graph.facebook.com/22222222/picture? type=square",
"name":"Etouda Gaudo",
"ink_id":"1",
"chat_id":"1",
"count":"1",
"last_message":"CoUcou"
}
]
}
the string to parse is equal to :
NSData *jsonData = [jsonResp dataUsingEncoding:NSUTF8StringEncoding];
NSError *error = nil;
NSDictionary *dictionary = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error];
NSLog(#"dictionary %#", dictionary);
and then I got the following result for the NSLog of dictionary :
dictionary {
count = 1;
data = (
{
"chat_id" = 1;
count = 1;
date = "Jeudi \U00e0 00:00:00";
"ink_id" = 1;
"last_message" = CoUcou;
name = "Test name";
picture = "http://graph.facebook.com/22222222/picture?type=square";
type = friend;
}
);
debugMessage = "<null>";
error = 0;
errorMessage = "<null>";
list = links;
}
I can't figure out why the " are missing...
Does anyone have a solution.
Thanks in advance.
NSLog is just a print representation for developers to view, it is the result of the description method being called on a class instance. Quotes are only added where the item might be ambitious without them such as a string with an embedded space. To verify that the JSON was parsed correctly validate it with code.
You are deserializing the JSON into an NSDictionary, which doesn't have to have quotes around it's property names, unlike JSON. Your parser is working correctly, but the NSLog of an NSDictionary won't show up exactly the same as the original JSON would.
I have the following JSON that validates as valid JSON..
{"flights":[{"flight":{"flightno":"BAW699","timestamp":"2011-03-22 07:06:02","route":"LOWW-EGLL"}},{"flight":{"flightno":"BAW706","timestamp":"2011-03-21 19:08:02","route":"EGLL-LOWW"}},{"flight":{"flightno":"BAW5MG","timestamp":"2011-03-21 16:33:02","route":"LEMG-EGLL"}},{"flight":{"flightno":"BAW3AG","timestamp":"2011-03-21 11:25:02","route":"EGLL-LEMG"}},{"flight":{"flightno":"BAW5EB","timestamp":"2011-03-20 19:18:02","route":"EGLL-LPPT"}},{"flight":{"flightno":"BA0489","timestamp":"2011-03-20 09:40:02","route":"LEBL-EGLL"}},{"flight":{"flightno":"BA0475","timestamp":"2011-03-19 16:51:02","route":"LEBL-EGLL"}},{"flight":{"flightno":"BAW489","timestamp":"2011-03-18 08:08:02","route":"LEBL-EGLL"}},{"flight":{"flightno":"BA0799","timestamp":"2011-03-17 18:37:02","route":"EGLL>EFHK"}},{"flight":{"flightno":"BAW799","timestamp":"2011-03-17 16:31:01","route":"EFHK-EGLL"}},{"flight":{"flightno":"BAW794","timestamp":"2011-03-17 11:55:02","route":"EGLL-EFHK"}},{"flight":{"flightno":"GEUUZ","timestamp":"2011-03-17 09:43:02","route":""}},{"flight":{"flightno":"BAW487","timestamp":"2011-03-16 19:32:01","route":"LEBL-EGLL"}},{"flight":{"flightno":"BAW486","timestamp":"2011-03-16 16:57:02","route":"EGLL-LEBL"}},{"flight":{"flightno":"BAW459","timestamp":"2011-03-16 14:10:01","route":"LEMD-EGLL"}},{"flight":{"flightno":"BAW41LM","timestamp":"2011-03-16 10:09:02","route":"EGLL-LEMD"}},{"flight":{"flightno":"BA0795","timestamp":"2011-03-16 08:27:02","route":""}},{"flight":{"flightno":"BAW795","timestamp":"2011-03-16 07:01:02","route":"EFHK-EGLL"}},{"flight":{"flightno":"BAW798","timestamp":"2011-03-15 18:23:02","route":"EGLL-EFHK"}},{"flight":{"flightno":"BAW701","timestamp":"2011-03-15 14:24:01","route":"LOWW-EGLL"}},{"flight":{"flightno":"BAW700","timestamp":"2011-03-15 11:04:01","route":"EGLL-LOWW"}},{"flight":{"flightno":"BAW68BL","timestamp":"2011-03-15 08:14:01","route":"LEBL-EGLL"}},{"flight":{"flightno":"BAW82BL","timestamp":"2011-03-14 18:40:03","route":"EGLL-LEBL"}},{"flight":{"flightno":"BAW849","timestamp":"2011-03-14 08:15:02","route":"EPWA-EGLL"}},{"flight":{"flightno":"BAW40CB","timestamp":"2011-03-13 19:30:03","route":"EGLL-LEBL"}},{"flight":{"flightno":"BAW475","timestamp":"2011-03-13 15:30:02","route":"LEBL-EGLL"}},{"flight":{"flightno":"z.NO-FLIGHTNO","timestamp":"2011-03-13 13:00:03","route":""}},{"flight":{"flightno":"BAW474","timestamp":"2011-03-13 12:00:03","route":"EGLL-LEBL"}},{"flight":{"flightno":"BAW4WP","timestamp":"2011-03-13 08:45:02","route":"LPPT-EGLL"}}]}
I then try and parse this using JSONKit but can only get as far down as "flights" I cannot seem to access the "flight" object.
When I do the following
-(void)parseJSON:(NSString *)jsonData{
NSDictionary *deserializedData = [jsonData objectFromJSONString];
for (id key in deserializedData) {
NSLog(#"key: %#, value: %#", key, [deserializedData objectForKey:key]);
}
}
Only the following is put out to the log....
key: flights, value: (
{
flight = {
flightno = BAW906N;
route = "EGLL-EDDF";
timestamp = "2011-03-24 08:38:02";
};
},
{
flight = {
flightno = BAW365;
route = "LFLL-EGLL";
timestamp = "2011-03-24 06:17:01";
};
},
{
flight = {
etc....
I want to be able to get down to each flight and at the moment am stuck!
Get an array of all flights like this:
NSArray *flights = [deserializedData valueForKeyPath:#"flights.flight"];
thats because you have an array of dictionairies in your dictionairy object, acces them like this:
for (NSDictionairy *flight in [deserializedData objectForKey:#"flights"]){
NSLog(#"flight object with route.: %#", [flight objectForKey:#"route"]);
}
