[英]get the value of ID from json response
我是iPhone App开发的新手。 我想从Facebook获取用户ID(我的ID)。 我如何获得ID? 控制台中的输出如下。
谢谢
- (void)request:(FBRequest *)request didLoad:(id)result
{
NSLog(@"result is %@",result);
}
控制台中的输出在这里:
{
email = "kestwalg@gmail.com";
"first_name" = Gaurav;
gender = male;
hometown = {
id = 1231243212321;
name = Haridwar;
};
id = 1213213231231;
"last_name" = K;
link = "http://www.facebook.com/kestwal.75";
locale = "en_US";
location = {
id = 123123123123;
name = "New Delhi, India";
};
name = "Gaurav Kestwal";
timezone = "5.5";
"updated_time" = "2012-07-10T06:46:25+0000";
username = "gaur.75";
verified = 1;
work = (
{
employer = {
id = 12312312312;
name = "NKAPs Intellects Noida";
};
position = {
id = 213123123213;
name = "iPhone Application Developer";
};
"start_date" = "0000-00";
}
);
}
实施SBJson 。
将json响应加载到NSDictionary中:
NSDictionary *myDictionary = [myJsonString JSONValue];
然后像这样从字典中读取:
NSString *idString = [myDictionary objectForKey:@"id"];
您只需要解析它,幸运的是,有多种方法可以在iPhone中轻松地做到这一点。 您可以使用此框架作为示例: JSON框架
试试看:
- (void)request:(FBRequest *)request didLoad:(id)result {
NSString *jsonString = [NSString stringWithString:[result JSONRepresentation]];
NSDictionary *userDict = [jsonString JSONValue];
// do something with the values in the dictionary...
}
