banner广告
<h1>banner广告(WindMillBannerView)</h1>
<p><strong>注意事项： 1、需要初始化时配置广告基本信息。例如期望尺寸，为避免渲染过程产生广告视图形变，务必和媒体平台配置相同尺寸； 2、通过设置WindMillBannerViewDelegate代理，获取广告、展示、点击、关闭等回调。值得注意的是一定要设置rootViewController，即跳转落地页需要的viewController； 3、banner广告视图需要开发者手动移除。</strong></p>

<h2>3. 调用示例</h2>
<h3>3.1 广告加载</h3>
<p>objective-c</p>
<pre><code>WindMillAdRequest *request = [WindMillAdRequest request];
request.userId = @&quot;user_id&quot;;
request.placementId = @&quot;聚合广告id&quot;;
request.options = @{@&quot;test_key&quot;:@&quot;test_value&quot;};//s2s激励时自定义参数，key和value都是媒体开发自定义
WindMillBannerView *bannerView = [[WindMillBannerView alloc] initWithRequest:request];
bannerView.delegate = self;
bannerView.viewController = self;
[bannerView loadAdData];
//在刷新成功和加载成功的回调中设置bannerView的frame
//成功加载广告
- (void)bannerAdViewLoadSuccess:(WindMillBannerView *)bannerAdView {
CGSize adSize = bannerAdView.adSize;
CGFloat space = (UIScreen.mainScreen.bounds.size.width - adSize.width)/2.0;
bannerAdView.frame = CGRectMake(space, 0, adSize.width, adSize.height);
}
//bannerView自动刷新
- (void)bannerAdViewDidAutoRefresh:(WindMillBannerView *)bannerAdView {
CGSize adSize = bannerAdView.adSize;
CGFloat space = (UIScreen.mainScreen.bounds.size.width - adSize.width)/2.0;
bannerAdView.frame = CGRectMake(space, 0, adSize.width, adSize.height);
}</code></pre>
<h2>4. Banner广告显示和隐藏时机</h2>
<h3>开启自动刷新功能</h3>
<p>当开启自动刷新功能时，开发者只需要调用loadAdData一次，在加载广告成功的回调（bannerAdViewLoadSuccess:）中可以把bannerView添加到屏幕上。</p>
<pre><code>- (void)bannerAdViewLoadSuccess:(WindMillBannerView *)bannerAdView {
CGSize adSize = bannerAdView.adSize;
CGFloat space = (UIScreen.mainScreen.bounds.size.width - adSize.width)/2.0;
bannerAdView.frame = CGRectMake(space, 0, adSize.width, adSize.height);
}</code></pre>
<p>在收到刷新成功的回调中（bannerAdViewDidAutoRefresh:）根据adSize调整BannerView的frame。</p>
<pre><code>- (void)bannerAdViewDidAutoRefresh:(WindMillBannerView *)bannerAdView {
CGSize adSize = bannerAdView.adSize;
CGFloat space = (UIScreen.mainScreen.bounds.size.width - adSize.width)/2.0;
bannerAdView.frame = CGRectMake(space, 0, adSize.width, adSize.height);
}</code></pre>
<p>在收到bannerAdViewDidRemoved:回调，可以移除bannerView，同时把bannerView释放掉。</p>
<pre><code>- (void)bannerAdViewDidRemoved:(WindMillBannerView *)bannerAdView {
[self.bannerView removeFromSuperview];
self.bannerView.delegate = nil;
self.bannerView = nil;
}</code></pre>
<h3>关闭自动刷新功能</h3>
<p>当不使用自动刷新功能时，开发者不会收到刷新成功和失败的回调。 当调用一次loadAdData加载广告成功时，开发者可将bannerView添加到屏幕上，当收到bannerAdViewDidRemoved:广告视图移除回调通知时，开发者需要主动调用[bannerView removeFromSuperview];方法移除bannerView； 若需要再次展示新的banner广告，开发者需要再次调用loadAdData接口，在加载成功的回调中，将对应的bannerView添加到屏幕即可。</p>
