IOS開發之——使用SBJson拼接Json字串

SBJson包的在上一篇文章中。

可以使用NSDictionary中的鍵值對來拼接Json資料，非常方便，也可以進行嵌套，直接上代碼：

    //開始拼接Json字串    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 dictionaryWithObjectsAndKeys:@"pv",@"pv",                                  parmDictionary,@"param",nil];    SBJsonWriter *writer = [[SBJsonWriter alloc] init];        NSString *jasonString = [writer stringWithObject:jsonDictionary];    NSLog(@"%@",jasonString);

上面的代碼用到了三層嵌套，注意的是，NSDictionary中，前面的是值，後面的是鍵。

拼接後的結果如下：

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

使用Json線上校正工具解析後：

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