iphone - Facebook 结果变成一个 NSArray

Question

我正在使用 Facebook api 获取用户的 friend 姓名、UID 和生日。我遇到的问题是，一旦我得到结果，我该如何获得这些值。意思是，我想获取每个返回值的用户名和生日？

这段代码一直让我崩溃

//set query
NSString *query =  @"SELECT uid, name, birthday_date FROM user WHERE uid IN " @"(SELECT uid2 FROM friend WHERE uid1 = me() LIMIT 25)";

// Set up the query parameter
NSDictionary *queryParam = [NSDictionary dictionaryWithObjectsAndKeys:query, @"q", nil];

[FBRequestConnection startWithGraphPath:@"/fql"
                             parameters:queryParam
                             HTTPMethod:@"GET"
                      completionHandler:^(FBRequestConnection *connection,
                                          id result,
                                          NSError *error) {
    if (error) {
            NSLog(@"Error: %@", [error localizedDescription]);
        } 
    else {
        NSLog(@"Result: %@", result);
        NSArray *friendInfo = (NSArray *) [result objectForKey:@"data"];
        NSArray *arryData3 = [[NSArray alloc] initWithArray:friendInfo];
        NSLog(@"[friendInfo count]: %d ... [arryData3 count]: %d ...",[friendInfo count],[arryData3 count]);
        for (int i=0; i<[arryData3 count]; i++) {
            NSArray *bdayArray = [[NSArray alloc] initWithArray:[arryData3 objectAtIndex:i]];
            //CODE CRASH HERE!!!!
            NSString *bdayStr = [bdayArray objectAtIndex:0];
            NSString *nameStr = [bdayArray objectAtIndex:1];
        }
    }
}];

这是我的崩溃日志的样子

data(
    {
        "birthday_date" = "01/06";
        name = "John Doe";
        uid = 555555;
    },
    {
        "birthday_date" = "09/01/1984";
        name = "Mrs. Smith";
        uid = 4444444;
    },
)
[friendInfo count]: 2 ... [arryData3 count]: 2 ...

对于任何可能对 future 感兴趣的人。这就是您如何在 Facebook 的结果中获得个人值(value)。

NSLog(@"Result: %@", result);
NSArray *friendInfo = (NSArray *) [result objectForKey:@"data"];
NSLog(@"[friendInfo count]: %d ....",[friendInfo count]);
for (int i=0; i<[friendInfo count]; i++)
{
    NSMutableString *userNameStr = [NSMutableString stringWithFormat:@"%@", [[friendInfo objectAtIndex:i]  objectForKey:@"name"]];
    NSMutableString *userDateStr = [NSMutableString stringWithFormat:@"%@", [[friendInfo objectAtIndex:i]  objectForKey:@"birthday_date"]];
    NSLog(@"userNameStr: %@ ... userDateStr: %@ ...", userNameStr,userDateStr);
   //From this point onwards you can put these individual strings into an array 
   //and if you had defined the array globally you can get to these results from 
   //any function in your code
}
