JSON Parsing Issue quotes and parenthesis

First of all thanks for the help guys in advance. I have found this forum to be of great help with getting the issues resolved that I am having coming from Android / HTML to IPhone / XCODE programming even if it is just pointing me in the right direction.

I have noticed something weird with the JSON parsing format. Half of the variables have quotes around them and the other half do not. They all have parenthesis around them as well.

Here is my json parsing code in the .m file

Code:

 NSString *strURL = [NSString stringWithFormat:@"http://10.4.4.11/ticket4/android5.php?Fone=%@&pincode=%@&confirm=%@&edit=Register", PhoneText, PinText,ConfirmText ];
    
    NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString : strURL]];
    
    NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];
    
    NSData * datajson = [strResult dataUsingEncoding: NSUTF8StringEncoding];
    
    id my2ConvertedJSONData = [NSJSONSerialization JSONObjectWithData : datajson options: NSJSONReadingMutableContainers error:&localError];
    
    if ([my2ConvertedJSONData isKindOfClass:[NSDictionary class]]) {
        NSLog(@"DICTIONARY");
        NSLog(@"dict3: %@", my2ConvertedJSONData);
    }
    
    if ([my2ConvertedJSONData isKindOfClass:[NSArray class]]) 
    {
        NSArray * anArray = my2ConvertedJSONData;
        NSLog(@"ARRAY count: %i", [anArray count]);
        if ([[anArray objectAtIndex: 0] isKindOfClass:[NSDictionary class]]) NSLog(@"Yep, dictionary inside of an array!");
        NSLog(@"Array dict index 0: %@", [anArray objectAtIndex: 0]);
        location =      [my2ConvertedJSONData valueForKey:(NSString *)@"location"];
        firstname =     [my2ConvertedJSONData valueForKey:@"firstname"];

and the results are

Code:

2012-06-11 22:27:58.867 tickets25[4846:f803] firstname = (
    John
)

and

2012-06-11 22:27:58.870 tickets25[4846:f803] location =  (
    "Las Vegas, NV"
)

If I can get rid of the parenthesis and the quotes it would make me a lot happier. It converts half my JSON data string that way and I can't figure out what its doing.

Thanks for all the help guys

Dejo,

What would you suggest as an alternative for ValueForKey statements ?

what is weird to me is that the json data does not have the quotes when I parse it with my android app nor does it mix my variables with quotes and no quotes. I understand what JSON data does (I did the programming on the php file that produces the JSON array from my webserver).

here is the full json parsing code

Code:

NSString *strURL = [NSString stringWithFormat:@"http://x.x.x.x/apps/apple.php?Fone=%@&pincode=%@&confirm=%@&edit=Register", PhoneText, PinText,ConfirmText ];
    
    NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString : strURL]];
    
    NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];
    
    NSData * datajson = [strResult dataUsingEncoding: NSUTF8StringEncoding];
    
    id my2ConvertedJSONData = [NSJSONSerialization JSONObjectWithData : datajson options: NSJSONReadingMutableContainers error:&localError];
    
    if ([my2ConvertedJSONData isKindOfClass:[NSDictionary class]]) {
        NSLog(@"DICTIONARY");
        NSLog(@"dict3: %@", my2ConvertedJSONData);
    }
    
    if ([my2ConvertedJSONData isKindOfClass:[NSArray class]]) 
    {
        NSArray * anArray = my2ConvertedJSONData;
        NSLog(@"ARRAY count: %i", [anArray count]);
        if ([[anArray objectAtIndex: 0] isKindOfClass:[NSDictionary class]]) NSLog(@"Yep, dictionary inside of an array!");
        NSLog(@"Array dict index 0: %@", [anArray objectAtIndex: 0]);
//        location =      [my2ConvertedJSONData valueForKey:(NSString *)@"location"];
        firstname =     [my2ConvertedJSONData valueForKey:@"firstname"];
        lastname =      [my2ConvertedJSONData valueForKey:@"lastname"];

because I am using several of the variables in another part of the program and the parenthesis screw it up with the text variables and another URL string that has to be built I am working on taking out the parenthesis and the quotes but I keep hitting roadblocks.

Point me in the right direction all mighty MAC God .

Thanks
John

 

Not doubting you PhoneyDeveloper (although your tag tends to lead to that conclusion Just Kidding,

But when I NSLog the entire string with it parsed out in the proper variables (there are more than just two) half of them have quotes and the other half do not. When I am working on rebuilding the next URL for my web views which they are using several variables that are in the JSON string the quotes show up as well as the parenthesis which as you can imagine completely jacks with the URL builds.

I am continuing to work through it to appease the MAC Gods (I am a PC / Linux guy normally)

also objectForKey throws an exception. just started working through that error


Thanks
John

 

Dejo,

I am straight looking for the value that is parsed out in the JSON String so "phone", "9095551212" with phone being the key and the number being the value for that key. This way i can place the variables where I need them else where in the code to help with other URLS and other items that I have in the program.

I am not at home so I don't have my programming information but all variables are property (non atomic, retain) nsstring * variable in the .h file and then synthesized on the .m file.

the full json string is

Code:

[{"id":"1","firstname":"John","lastname":"Schimanski","phonenumber":"9093768439","company":"195300","pincode":"12345678","email":"jfschimanskijr@gmail.com","confirmationcode":"12345","item":"AA","price":"5","desc":"12","retrieved":"no","sku":"154784596124","salesrep":"john doe","customercompanylogo":"customer1.png","billingcontactname":"jane doe","contactnumber":"9093768439","datetime":"2013-01-01 19:00:00","location":"Las Vegas, Nevada","count":"59"}]


and this is what happens when NSLog the dict index 0

 Array dict index 0: {
    confirmationcode = 12345;
    count = 59;
    datetime = "2013-01-01 19:00:00";
    email = "jfschimanskijr@gmail.com";
    firstname = John;
    id = 1;
    lastname = Schimanski;
    location = "Las Vegas, Nevada";
    phonenumber = 9093768439;
    pincode = 12345678;
    retrieved = no;
    price = 5;
    company = 195300;
    price = 12;
    item = AA;
    sku = 154784596124;
    salesrep = "john doe";
    companylogo = "customer1.png";
    contactname = "9093768439";
    oppcompany= "original1.png";
}


When I place them into their individual variables they end up like what I said before the parenthesis and quotes but the quotes are not on all of them but the parenthesis are.

what I am thinking that I am doing wrong is doubling up the variables somehow and then its quoting them in the valueForKey statement.

Dejo and Chown33

I managed to solve the problem and get them out of the quotes and the parenthesis. Thanks for pointing me in the right direction.

I plan on doing that . It was late and I was frustrated with another problem with the code, so that I have a full record of what the problem was and how to solve it for my own future reference.
