How to generate a JSON string compatible with Objective-C syntax

Question

I need some kind of json string generator for objective-c. Actually I thought there must be something like that but I could not find anything.To be specific, for example I have a json string like:

{"name":"abc","email":"[email protected]","password":"1"}

when I want to store it in objective c, I have to write it like:

@"{\"name\":""\"abc\""",\"email\":""\"[email protected]\""",\"password\":""\"1\"""}"

so it is confusing and hard to implement. Are there any generators or an easy way to implement it. Thanks

You have a JSON string like that where? In a file?? What do you mean by "store it in objective c"? — borrrden

Convert your json string to dictionary...

NSData* data = [yourJsonString dataUsingEncoding:NSUTF8StringEncoding];
            NSDictionary* jsonDict = [NSJSONSerialization
                                      JSONObjectWithData:data
                                      options:kNilOptions
                                      error:&error];
 NSLog(@"jsonDict:%@",jsonDict);

You can use the native ios SDK API's for generating JSON data from NSDictionary / NSArray.

e.g.,

NSData *jsondata = [NSJSONSerialization dataWithJSONObject:(dictobject) options:NSJSONWritingPrettyPrinted error:&error];

NSString *str = [[NSString alloc] initWithData:jsondata encoding:NSUTF8StringEncoding];

may this helps!

Use it Also Import"JSON.H"

 NSDictionary *googleResponse = [[NSString stringWithContentsOfURL:[NSURL  URLWithString:website] encoding: NSUTF8StringEncoding error: NULL] JSONValue];

be careful...in your original question, when referring to how to store it in objective-c, i think you made a mistake

you wrote : @"{\"name\":""\"abc\"""

when it shoud be @"{\"name\":\"abc\",....etc...

i think you doubled the quotes...be wary, cause in the beginning there already is one opening double-quote @", all the other needed quotes must be escaped like so \", and then also have an ending quote as well.

hope it helps
