            "isReserved": false,
            "label": " ",
            "begin": "2012-09-01 16:30:00 America/Los_Angeles",
            "end": "2012-09-01 17:00:00 America/Los_Angeles",
            "span": 1
        }
    ]
}

これが私がこれまでに持っているものです

- (void)fetchedData:(NSData *)responseData {
    //parse out the json data

    NSError* error;
    //NSLog(@"string is %@", responseData);

    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error];

    NSDictionary* myslots =[json objectForKey:@"slots"];
NSLog(@"allslots: %@", myslots);
//for (NSString *slotKey in myslots.allKeys) {
    //NSDictionary *slot = [myslots valueForKey:slotKey];
    //NSLog(@"These are all the keys: %@", slotKey);
    NSArray *keys = [myslots allKeys];

更新-これは私がそれを機能させる方法です：

for (NSString *slotKey in myslots.allKeys) {
    NSDictionary *slot = [myslots valueForKey:slotKey];
        NSArray *tests = [myslots objectForKey:slotKey];
    for (NSDictionary *myDict in tests){
        NSLog(@"%@", [myDict objectForKey:@"begin"]); 
    }
    }

ここで、「isReservable」= trueの場合、「begin」を表示するように変更する必要があります。

Answer 1

myslotsはNSArrayではなくNSDictionaryのようです...すべてのキーを反復処理するには、変更します

for (NSDictionary *slots in myslots) {
    // code
}

にとって

for (NSString *slotKey in myslots.allKeys) {
    NSDictionary *slot = [myslots valueForKey:slotKey];
    // code
}

Answer 2

myslotsは辞書です。最初のキー「2012-08-3000:00:00America / Los_Angeles」は、探しているアレイに関連付けられているキーのようです。ディクショナリ内の値にアクセスするためのキーとして実際の静的キーを持つようにデータを再構築することをお勧めします。
