我有一个NSDictionary,我不知道如何检索“@mode”和“@route”(这是从JSON响应)的值。NSDictionnary检索值
我该怎么做?
谢谢!
这是的NSDictionary:
{
"@mode" = WALK;
"@route" = "Rue University";
distance = "17.513516908661757";
duration = 13000;
endTime = "2011-04-29T12:08:59.395-04:00";
from = {
geometry = "{\"type\": \"Point\", \"coordinates\": [-73.57120386807037,45.503820214186405]}";
lat = "45.503820214186405";
lon = "-73.57120386807037";
name = "Rue University";
};
legGeometry = {
length = 3;
points = "{mvtG`k``[email protected]";
};
startTime = "2011-04-29T12:08:46.395-04:00";
steps = {
walkSteps = (
{
absoluteDirection = NORTHWEST;
becomes = false;
distance = "17.513516908661757";
elevation = "";
lat = "45.503820214186405";
lon = "-73.57120386807037";
stayOn = false;
streetName = "Rue University";
},
{
absoluteDirection = NORTH;
becomes = true;
distance = "0.0";
elevation = "";
lat = "45.50390573910769";
lon = "-73.57139257694809";
relativeDirection = RIGHT;
stayOn = false;
streetName = "street transit link";
}
);
};
to = {
geometry = "{\"type\": \"Point\", \"coordinates\": [-73.571363,45.503971]}";
lat = "45.503971";
lon = "-73.571363";
name = "Station McGill";
stopId = 32;
};
这看起来更像是一个字典而不是数组。 – Caleb 2011-04-29 16:19:21
