先生、iPhone開発は初めてです。URLリクエストで緯度と経度を送信せずに新しい場所を取得する方法を知る必要があります.

 NSURL *URL = [NSURL URLWithString:@"https://maps.googleapis.com/maps/api/place/search           /json?location=40.7143528,-74.0059731&radius=10000&types=school&sensor=false&key=AIzaSyDbiWWIOmc08YSb9DAkdyTWXh_PirVuXpM"];

これは私のコードです。iat と lang の値を使用して URL リクエストを介してリクエストしましたが、この 2 つの値なしで指定する必要があります。ただし、現在の値を取る必要があります
