        },
        {
            "isPending": false,
            "isReservable": true,
            "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
        }
    ]
}

这是我到目前为止所掌握的

代码语言：javascript
复制
- (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-这是我让它工作的方式：

代码语言：javascript
复制
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"]); 
    }
    }

现在我只需要将其更改为如果"isReservable“= true，则显示"begin”

看起来我的槽是一个NSDictionary，而不是一个NSArray ...要遍历它的所有键，请更改

代码语言：javascript
复制
for (NSDictionary *slots in myslots) {
    // code
}

为

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

我的槽是一本字典。看起来第一个键"2012-08-30 00:00:00 :00america/Los Angeles“就是与您要查找的数组相关联的键。我建议您重新构造数据，使用一个实际的静态键作为访问字典中的值的键。
