MoPub 如何使用具有动态单元格高度的 MPTableViewAdPlacer 实现 iOS 原生广告？
MoPub How to implement iOS Native Ads using MPTableViewAdPlacer with dynamic cell height?
我正在使用 MPTableViewAdPlacer 在 iOS UITableView 中实现原生广告。初始化 MPTableViewAdPlacer 时，它会请求 MPStaticNativeAdRendererSettings，这需要实现 viewSizeHandler。但是，这是在获取任何广告之前，正如名称所建议的那样 "Static" 原生广告。我正在尝试实现一个在获取 adData 后可以计算单元格高度的方法，例如标题、图像等。我一直在尝试寻找一种方法来实现动态单元格高度，但所有示例应用程序，Twitter 提供的说明仅显示静态高度实现。
代码如下：
-(void)setupAdPlacer {
MPNativeAdRequestTargeting *targeting = [MPNativeAdRequestTargeting targeting];
targeting.location = [[CLLocationManager alloc] init].location;
targeting.desiredAssets = [NSSet setWithObjects: kAdMainImageKey, kAdCTATextKey, kAdTextKey, kAdTitleKey, nil];
MPStaticNativeAdRendererSettings *settings = [[MPStaticNativeAdRendererSettings alloc] init];
settings.renderingViewClass = [REPostListViewMoPubAdCell class];
settings.viewSizeHandler = ^(CGFloat maximumWidth) {
return CGSizeMake(maximumWidth, 312.0);
// STATIC HEIGHT
};
MPNativeAdRendererConfiguration *config = [MPStaticNativeAdRenderer rendererConfigurationWithRendererSettings:settings];
self.adPlacer = [MPTableViewAdPlacer placerWithTableView:self.tableView viewController:self adPositioning:positioning rendererConfigurations:@[config]];
self.adPlacer.delegate = self;
[self.adPlacer loadAdsForAdUnitID:@"xxxxxxxxxxx" targeting:targeting];
}
你需要根据你的screen和tableview来决定高度和宽度。我已经在运行时设置了所有组件并且运行良好。
我正在使用设置 mopub。
-(void)setUpMopPubAd
{
MPServerAdPositioning *positioning = [[MPServerAdPositioning alloc] init];
self.placer = [MPTableViewAdPlacer placerWithTableView:tableViewContent viewController:self adPositioning:positioning defaultAdRenderingClass:[MoPubAdTableViewCell class]];
MPNativeAdRequestTargeting *targeting = [MPNativeAdRequestTargeting targeting]; targeting.desiredAssets = [NSSet setWithObjects:kAdIconImageKey, kAdMainImageKey, kAdCTATextKey, kAdTextKey, kAdTitleKey, nil];
[self.placer loadAdsForAdUnitID:kMoPubKey];
[tableViewContent mp_setDataSource:self];
[tableViewContent mp_setDelegate:self];
}
我已经为 MoPubAd 创建了 tableviewcell。

希望对您有所帮助。
注意：无论您使用哪种表视图方法，请在 ViewController 中使用带有 mp_ 前缀的方法。
联系 Twitter 技术支持后，我确认目前 iOS 不支持动态单元格高度。唯一的方法是根据@Vatsal K 在他上面的评论中指出的最佳实践调整你的观点。
更新： 虽然下面的方法适用于现有的 MoPub Marketplace 适配器，但我在 MoPub 的 SDK 中发现了一个错误，该错误可能会导致其他适配器出现问题。具体来说，如果您使用此方法，则不会出现 Facebook 的隐私图标视图。 retrieveAdViewForSizeCalculationWithError 呼叫 retrieveViewWithAdapter。这将实例化一个新的 adview 以用于调整大小（因此此方法也可能不是很有效）。当该方法将自定义网络适配器隐私视图添加为子视图时，问题就出现了。因为 MoPub 没有实例化一个新的适配器，所以适配器的隐私视图作为子视图添加到这个模板 adview 中，并从真正的 adview 中删除。小心行事。
我找到了解决方法，但它依赖于 MoPub SDK 接口未公开的常量。
如果你看MPStreamAdPlacer
- (CGSize)sizeForAd:(MPNativeAd *)ad withMaximumWidth:(CGFloat)maxWidth andIndexPath:(NSIndexPath *)indexPath
{
id<MPNativeAdRenderer> renderer = ad.renderer;
CGSize adSize;
if ([renderer respondsToSelector:@selector(viewSizeHandler)] && renderer.viewSizeHandler) {
adSize = [renderer viewSizeHandler](maxWidth);
if (adSize.height == MPNativeViewDynamicDimension) {
UIView *adView = [ad retrieveAdViewForSizeCalculationWithError:nil];
if (adView) {
CGSize hydratedAdViewSize = [adView sizeThatFits:CGSizeMake(adSize.width, CGFLOAT_MAX)];
return hydratedAdViewSize;
}
}
return adSize;
}
此方法由 MPTableViewAdPlacer 调用以获取广告的尺寸。它反过来使用您在配置放置器时设置的 viewSizeHandler。请注意，如果 returned 高度等于 MPNativeViewDynamicDimension (-1.0)，则它会回退到在广告视图上调用 -sizeThatFits:。
此时已使用来自广告服务器的数据配置了广告视图，因此您可以实施 -sizeThatFits: 和 return 适合内容的尺寸：
// MoPub setup
MPStaticNativeAdRendererSettings *settings = [[MPStaticNativeAdRendererSettings alloc] init];
settings.renderingViewClass = [MyAdView class];
settings.viewSizeHandler = ^(CGFloat maxWidth) {
return CGSizeMake(maxWidth, -1.0);
};
MyAdView class:
- (CGSize)sizeThatFits:(CGSize)size {
// Inspect the configured labels and images to determine appropriate height for given size.width
CGFloat height = ...
return CGSizeMake(size.width, height);
}
警告
MPNativeViewDynamicDimension 是内部 MPStaticNativeAdRenderer，因此值和行为可能会更改，恕不另行通知。可能值得添加对链接的 SDK 版本的检查，如果它发生变化，则发出警告以检查实施是否仍然有效
