使用JSON向Google Maps詢問商店

Question

我正在使用JSON iPhone框架v2.3.1，並且想要查詢有關商店，酒店等的Google地圖。可以創建一個URL向我列出一個列表方向？

其實我正在使用這個Objective C代碼。

- (void) searchCoordinatesForAddress { 

    //Build the string to Query Google Maps. 
    //I don't know how to change this URL direction. 
    NSMutableString *urlString = [NSMutableString stringWithFormat:@"http://maps.google.com/maps/geo?q=Paris?output=json"]; 

    //Replace Spaces with a '+' character. 
    [urlString setString:[urlString stringByReplacingOccurrencesOfString:@" " withString:@"+"]]; 

    //Create NSURL string from a formate URL string. 
    NSURL *url = [NSURL URLWithString:urlString]; 

    //Setup and start an async download. 
    //Note that we should test for reachability!. 
    NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url]; 
    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 

    [connection release]; 
    [request release]; 
} 

感謝您的閱讀。

檢查spatial search。

另外，如果您想要實施對商店列表的搜索，那麼您可以考慮使用Google的我的地圖功能。您可以上傳商店列表並搜索特定列表。
