IOS development-splicing Json strings with SBJson

The SBJson package is in the previous article.

You can use the key-value pairs in NSDictionary to splice Json data, which is very convenient and can also be nested and directly run the Code:

// Start splicing the Json string NSDictionary * dataDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @ "mac", @ "mac", @ "game", @ "game", @ "devicetoken ", @ "devicetoken", @ "device", @ "device", @ "gv", @ "gv", @ "lang", @ "lang", @ "OS ", @ "OS", nil]; NSDictionary * parmDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @ "getSession", @ "act", dataDictionary, @ "data", nil]; NSDictionary * jsonDictionary = [NSDictionary dictionary: @ "pv", @ "pv", parmDictionary, @ "param", nil]; SBJsonWriter * writer = [[SBJsonWriter alloc] init]; NSString * jasonString = [writer stringWithObject: jsonDictionary]; NSLog (@ "% @", jasonString );

The above Code uses layer-3 nesting. Note that in NSDictionary, values are preceded by keys.

The result after splicing is as follows:

{"pv":"pv","param":{"act":"getSession","data":{"os":"os","mac":"mac","game":"game","gv":"gv","lang":"lang","devicetoken":"devicetoken","device":"device"}}}

After parsing using the Json online verification tool:

{    "pv": "pv",    "param": {        "act": "getSession",        "data": {            "os": "os",            "mac": "mac",            "game": "game",            "gv": "gv",            "lang": "lang",            "devicetoken": "devicetoken",            "device": "device"        }    }}
