Native

First you need to create a request and execute it

self.request = [BDMNativeAdRequest new];
    [self.request performWithDelegate:self];

After polling, you need to save the bid request ([BDMRequestStorage.shared saveRequest:request];)

#pragma mark - BDMRequestDelegate

- (void)request:(BDMRequest *)request completeWithInfo:(BDMAuctionInfo *)info {
    // After request complete loading application can lost strong ref on it
    // BidMachineFetcher will capture request by itself
    self.request = nil;
    // Save request for bid
    [BDMRequestStorage.shared saveRequest:request];
    // Here we define which Admob ad should be loaded
    [self makeRequest];
}

Then you can create an Admob object and load it

- (void)makeRequest {
    GADRequest *request = [GADRequest request];
    [self.nativeLoader loadRequest:request];
}

- (GADAdLoader *)nativeLoader {
    if (!_nativeLoader) {
        _nativeLoader = [[GADAdLoader alloc] initWithAdUnitID:@UNIT_ID
                                           rootViewController:self
                                                      adTypes:@[kGADAdLoaderAdTypeNative]
                                                      options:@[self.viewOptions, self.videoOptions, self.mediaOptions]];
        _nativeLoader.delegate = self;
    }
    return _nativeLoader;
}

- (GADAdLoaderOptions *)videoOptions {
    GADVideoOptions *options = GADVideoOptions.new;
    options.startMuted = YES;
    return options;
}

- (GADAdLoaderOptions *)mediaOptions {
    GADNativeAdMediaAdLoaderOptions *options = GADNativeAdMediaAdLoaderOptions.new;
    options.mediaAspectRatio = GADMediaAspectRatioLandscape;
    return options;
}

- (GADAdLoaderOptions *)viewOptions {
    GADNativeAdViewAdOptions *options = GADNativeAdViewAdOptions.new;
    options.preferredAdChoicesPosition = GADAdChoicesPositionTopRightCorner;
    return options;
}
