一連の緯度と経度のポイントを取得し、それらを使用してマップ マーカーをプロットする必要がありますが、何らかの理由でそれらを double 値として格納してメソッドに渡すことができません。これを使用して値をログアウトしようとしました：
// Make the URL connection
NSString *urlAsString = @"...........";
NSURL *url = [NSURL URLWithString:urlAsString];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
// Error and success message handling.
[NSURLConnection
sendAsynchronousRequest:urlRequest
queue:queue
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if([data length] > 0 &&
error == nil){
NSData *jsonData = [NSData dataWithContentsOfURL:url];
if (jsonData != nil){
NSError *error = nil;
self.result = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];
if(error == nil)
NSLog(@"Longitude: %@",[_result valueForKeyPath:@"merchants.branches.longitude"]);
NSLog(@"Name: %@", [_result valueForKeyPath:@"merchants.branches.name"]);
}
}
else if ([data length] == 0 &&
error == nil){
NSLog(@"Nothing was downloaded");
}
else if (error != nil){
NSLog(@"Error happened = %@", error);
}
}];
}
これが送り返されるデータです。

今、これらの値のそれぞれを取得し、メソッドを介して送信するために doublevalue として格納する for ループを作成しようとしています。forループは次のとおりです。
for(NSDictionary *location in _result) {
CLLocationCoordinate2D annotationCoordinate =
CLLocationCoordinate2DMake([location valueForKey:@"merchants.branches.latitude"] doubleValue]]),
([location valueForKey:@"merchants.branches.longitude"] doubleValue]]);
Annotation *annotation = [[Annotation alloc] init];
annotation.coordinate = annotationCoordinate;
annotation.title = location[@"name"];
annotation.subtitle = nil;
[self.mapView addAnnotation:annotation];
何が起こっているのかわかりませんが、エラーが返され続けます。何か案は？呼び出そうとしているキーに関係していることはわかっています。
