无法识别的选择器发送到实例 |目标 C

Question

应用程序在启动时崩溃，我在控制台中出现此错误：

由于未捕获的异常而终止应用程序 'NSInvalidArgumentException'，原因：'-[Chartboost showInterstitial]： 无法识别的选择器发送到实例 0x7f844c9b74e0'

我的代码是：

#import "AppSpecificValues.h"
#import <RevMobAds/RevMobAds.h>

#import <Chartboost/Chartboost.h>

和其他代码。 我尝试了很多东西！所以我现在问你，我该如何解决这个问题？？？ 提前致谢！

Answer 1

根据Chartboost documentation，您并没有尝试以正确的方式显示插页式广告：

4. 要展示静态或插页式视频广告：

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

在他们的 SDK 5.x 中删除了您的操作方式

所有对 [Chartboost sharedChartboost] 的引用现在都更改为 Chartboost：

• [[Chartboost sharedChartboost] showInterstitial:CBLocationHomeScreen];现在是 [Chartboost showInterstitial:CBLocationHomeScreen];

Answer 2

您正在对实例调用 showInterstitial，尽管它是一个类方法。它应该类似于[Chartboost showInterstitial...
