私がやろうとしているのは、JSON フィードを取得して、結果をループすることです。ただし、辞書からオブジェクトを取得すると、配列ではなく文字列を取得し続けます。私が間違っていることについてのアイデアはありますか?
JSONは次のとおりです。
[
{
"_id": "4f6d9a7c1d0b4900010007ee",
"geo_triggers": [
{
"_id": "4fc3e5fdc7234e0001000002",
"location": [1,1],
"longitude": "1",
"latitude": "1",
"radius": 1,
"location_name": "Test 1"
},
{
"_id": "4fc61f3762f53f0001000043",
"location": [-71.057673,42.355395],
"longitude": "-71.057673",
"latitude": "42.355395",
"radius": 1000,
"location_name": "Test2"
}
]
}
]
目的の C コードは次のとおりです。
const char* className = class_getName([result class]);
NSLog(@"Result is a: %s", className);
NSLog(@"%@", result); //string
NSArray* json = [result objectForKey:@"result"]; //should be an array of dictionaries
NSLog(@"JSON Output: %@", json);
const char* className1 = class_getName([json class]);
NSLog(@"yourObject is a: %s", className1);
出力は次のとおりです。
Result is a: __NSDictionaryI
