How return data from an HTTP request in Swift/Objective C

Question

I\'m trying to use Coinbase\'s API to get information about my online bitcoin wallet, and I\'m trying to use Swift\'s NSURLSession object to do so. Perhaps I\'m missing some

Answer 1

In objective-C you can use __block and get the data when the operation finishes:

__block NSData *myData;
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:urlString]
      completionHandler:^(NSData *data,
                          NSURLResponse *response,
                          NSError *error) {
        myData = data;

}] resume];
