我是新程序员。我正在使用 Google Matrix API。我得到以下响应我想要获取“文本”:“1686 公里”。我正在使用 Json 解析。谢谢
"destination_addresses" : [ "San Francisco, Californie, États-Unis" ],
"origin_addresses" : [ "Vancouver, BC, Canada" ],
"rows" : [
{
"elements" : [
{
"distance" : {
"text" : "1 686 km",
"value" : 1685690
},
"duration" : {
"text" : "3 jours 21 heures",
"value" : 336418
},
"status" : "OK"
}
]
}
],
"status" : "OK"
}
SBJsonParser *json = [[SBJsonParser new] autorelease];
NSError *jsonError;
parsedJSON = [json objectWithString:data error:&jsonError];
最佳答案
嗯，parsedJSON将是一个NSDictionary，所以:
NSArray *rows = [parsedJSON objectForKey:@"rows"];
for (NSDictionary *row in rows) {
NSArray *elements = [row objectForKey:@"elements"];
for (NSDictionary *element in elements) {
NSDictionary *distance = [element objectForKey:@"distance"];
NSString *kmDistance = [distance objectForKey:@"text"]; ///< That's what you wanted
}
}
关于iphone - JSON 解析。值不是以公里为单位，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9681913/
