iOS9 sendSynchronousRequest deprecated

Question

Warning:\'sendSynchronousRequest(_:returningResponse:)\' was deprecated in iOS 9.0: Use [NSURLSession dataTaskWithRequest:completionHandler:] (see NSURLSe

Answer 1

I have modified the code of Nilesh Patel a little bit, so you can use the old call, just by changing class name.

+ (NSData *)sendSynchronousRequest:(NSURLRequest *)request returningResponse:(NSURLResponse **)response error:(NSError **)error {
__block NSData *blockData = nil;
@try {

        __block NSURLResponse *blockResponse = nil;
        __block NSError *blockError = nil;

        dispatch_group_t group = dispatch_group_create();
        dispatch_group_enter(group);

        NSURLSession *session = [NSURLSession sharedSession];
        [[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable subData, NSURLResponse * _Nullable subResponse, NSError * _Nullable subError) {

            blockData = subData;
            blockError = subError;
            blockResponse = subResponse;

            dispatch_group_leave(group);
        }] resume];

        dispatch_group_wait(group,  DISPATCH_TIME_FOREVER);

        *error = blockError;
        *response = blockResponse;

    } @catch (NSException *exception) {

        NSLog(@"%@", exception.description);
    } @finally {
        return blockData;
    }
}
