Splitting JSON data in iPhone - iphone

Question

I got this data from my server using JSON:
{
ID = 198;
dtDate = "2012-03-14 00:00:00";
dtTime = "06:00:00";
iPublished = 1;
sProgram = "Devotional Hits";
}
{
ID = 199;
dtDate = "2012-03-14 00:00:00";
dtTime = "07:00:00";
iPublished = 1;
sProgram = "Old Malayalam Hits";
}
{
ID = 200;
dtDate = "2012-03-14 00:00:00";
dtTime = "08:00:00";
iPublished = 1;
sProgram = "Malayalam New Hits";
}
{
ID = 201;
dtDate = "2012-03-14 00:00:00";
dtTime = "09:00:00";
iPublished = 1;
sProgram = "Melody Songs";
}
{
ID = 202;
dtDate = "2012-03-14 00:00:00";
dtTime = "10:00:00";
iPublished = 1;
sProgram = "Jayachandran Hits";
}
{
ID = 203;
dtDate = "2012-03-14 00:00:00";
dtTime = "11:00:00";
iPublished = 1;
sProgram = "Yesudas Hits";
}
{
ID = 204;
dtDate = "2012-03-14 00:00:00";
dtTime = "12:00:00";
iPublished = 1;
sProgram = "Ilayaraja Hits";
}
I need to split this data and store sProgram data into an array.. need help.
I need to split this format and I want sProgram and dtTime separately. What should I do for that. I'm a little bit confused about string formatting.

If you are using < IOS 5, add SBJSON to your project
//in some.m file
#import JSON.h
// Lets say NSString *recievedValue contains your JSON response.
id jsonRep = [receivedValue jsonValue];
if([jsonRep isKindOfClass:[NSArray class]])
{
// returned JSON Value has a array structure.
NSArray *value = (NSArray *)jsonRep;
//You can access values using objectAtIndex: method if you already know the Index of a value, in your case i think each array object is a NSDictionary
if([[value objectAtIndex:0] isKindOfClass:[NSDictionary class]])
{
// returned JSON Value has a key value compliant structure.
NSDictionary *dicValue = (NSDictionary *)[value objectAtIndex:0];
//You can access values using objectForKey: method if you already know the key value, in your case it can be #"sProgram" for example
}
}
else if([jsonRep isKindOfClass:[NSDictionary class]])
{
// returned JSON Value has a key value compliant structure.
NSDictionary *value = (NSDictionary *)jsonRep;
//You can access values using objectForKey: method if you already know the key value, in your case it can be #"sProgram" for example
}

Your JSON is invalid - I recommend that you use this tool to check this before posting about a JSON-related issue in the future.
However, I have corrected your JSON and validated it - it should look like this:
[
{
"ID": 198,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "06:00:00",
"iPublished": 1,
"sProgram": "Devotional Hits"
},
{
"ID": 199,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "07:00:00",
"iPublished": 1,
"sProgram": "Old Malayalam Hits"
},
{
"ID": 200,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "08:00:00",
"iPublished": 1,
"sProgram": "Malayalam New Hits"
},
{
"ID": 201,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "09:00:00",
"iPublished": 1,
"sProgram": "Melody Songs"
},
{
"ID": 202,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "10:00:00",
"iPublished": 1,
"sProgram": "Jayachandran Hits"
},
{
"ID": 203,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "11:00:00",
"iPublished": 1,
"sProgram": "Yesudas Hits"
},
{
"ID": 204,
"dtDate": "2012-03-14 00:00:00",
"dtTime": "12:00:00",
"iPublished": 1,
"sProgram": "Ilayaraja Hits"
}
]
You can then use the json-framework to parse it.
As you asked, here is how you can now obtain all the values of sProgram:
NSMutableArray *programs = [[NSMutableArray alloc] init];
NSArray *data = [json jsonValue];
for (NSDictionary *dict in data) {
[programs addObject:[dict objectForKey:#"sProgram"]];
}
// programs now contains all the values of sProgram

actually i used Stig Brautaset’s JSON library (version 2.2)
- (void)viewDidLoad
{
[super viewDidLoad];
[table reloadData];
NSMutableData *responseData;
responseData = [[NSMutableData data] retain];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://ganamradio.com/smartphones/date.php"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
// Do any additional setup after loading the view from its nib.
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
[responseData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
//label.text = [NSString stringWithFormat:#"Connection failed: %#", [error description]];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
//[responseData release];
dict=[responseString JSONValue];
NSArray *Programs;
NSArray *Time;
Programs=[dict valueForKey:#"sProgram"];
Time=[dict valueForKey:#"dtTime"];
NSLog(#"......%#",Time);
}
so i got the program list in NSArray programs,, is their any problem using like this..?
