Question

此响应中存在语法错误（google api响应），我想从此响应中获取Points的数据。我怎么才能得到它。

{
    tooltipHtml:" (9.6 km / 18 mins)",
    polylines:[
    {
    id:"route0",
    points:"_y}oBwxiaM{CdCaAh@}IvAgAB_BOqLgBgCXqFhB_GdCoAnAcGlHuAjA_Bb@oBAy@MsVqI{DgBgC{AmE{EqA{Be@oCLcDvDaRPeDGiBY_Bi@mAyAiB{@g@aC_AyT{FyCcBqMoIqQ{I??URSCIMJ]UuASuGN}THiCd@_GWyGiB}GmCyPwAwLqCqq@}CqMsBkMGiFMOWwDIwDg@mC]}@??k@s@oBD??yDvAqPpKeEfBcJdGoD~@sBAqAYcBm@mBY??`@g@l@[??RyAQoA",

    numLevels:4,
    zoomFactor:16
    }
    ]
    }

如果您需要json数据

，请使用此NSJSONSerialization

+ (NSData *)dataWithJSONObject:(id)obj options:(NSJSONWritingOptions)opt 
error:(NSError **)error

如何从这种错误的JSON格式中获取所需的数据？
