未识别的选择器已发送到实例|目标C

Question

启动上的应用程序崩溃，我在控制台中有一个错误：

由于未被发现的例外，终止应用程序 " nsinvalidargumentException"，原因：' - [Chartboost ShowInterstitial]： 未识别的选择器发送到实例0x7f844c9b74e0'

我的代码是：

和其他代码。我尝试了很多东西！所以我现在问你，如何解决这个问题？？？预先感谢！

Answer 1

根据Chartboost文档，您不是要以正确的方式显示间隙：

4. 显示静态或间隙视频广告：

// Show interstitial at location HomeScreen. See Chartboost.h for available location options.
[Chartboost showInterstitial:CBLocationHomeScreen];

您这样做的方式已在他们的SDK 5.x

中删除

所有对[ChartBoost sharedChartboost]的参考现在已更改为 Chartboost：

• [[ChartBoost共享Chartboost] show Interstitial：cBlocationHomescreen];现在[ChartBoost showinterstitial：cblocationhomescreen];

Answer 2

您在实例上调用ShowInterstitial，尽管它是类方法。它应该是[Chartboost showInterstitial...
