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

这是我到目前为止所拥有的

- (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 - 这就是我让它工作的方式：

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"]); 
    }
    }

现在我只需要把它改成 if "isReservable" = true 然后显示 "begin"

it looks like myslots is an NSDictionary, not an NSArray ... to iterate through all it's keys, change

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

for

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

myslots 是一本字典。似乎第一个键“2012-08-30 00:00:00 America/Los_Angeles”是与您要查找的数组相关联的键。我建议重组您的数据，使其具有一个实际的静态键作为访问字典中值的键。
