發送到實例|的無法識別的選擇器目標C

Question

上啓動的應用程序崩潰，我必須在控制檯此錯誤：

終止應用程序由於未捕獲的異常 「NSInvalidArgumentException」的，理由是：「 - [Chartboost showInterstitial]： 無法識別的選擇發送到實例0x7f844c9b74e0'

我的代碼是：

和其他代碼。 我嘗試了很多東西！所以我現在問你，我該如何解決這個問題？ 提前致謝！

Answer 1

根據Chartboost documentation你是不是想表明間質的正確方法：

要顯示靜態或插播視頻廣告：

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

你正在做它的方式已經在他們的SDK 5.x的

被刪除

爲[Chartboost sharedChartboost的所有參考文獻現在被改變爲 Chartboost：

• [[Chartboost sharedChartboost] showInterstitial：CBLocationHomeScreen];現在[Chartboost showInterstitial：CBLocationHomeScreen];

Answer 2

對一個實例調用showInterstitial，儘管它是一個類方法。它應該像[Chartboost showInterstitial...
