我已经在我的Swift应用中成功设置了Chartboost，但想在插页式视图关闭时的某些时间调用函数。
我对Objective-C的经验几乎为零（可能是问题），但是由于能够访问Chartboost类和整个过程正常工作，因此我的Obj-C文件显然已链接。
我在几个地方尝试了以下方法，但均未成功：
func didCloseInterstitial(location: CBLocation) {
print("closing interstitial")
}
func didDismissInterstitial(location: CBLocation) {
print("dismissing interstitial")
}
这是Obj-C文档：
/*!
@abstract
Called after an interstitial has been dismissed.
@param location The location for the Chartboost impression type.
@discussion Implement to be notified of when an interstitial has been dismissed for a given CBLocation.
"Dismissal" is defined as any action that removed the interstitial UI such as a click or close.
*/
- (void)didDismissInterstitial:(CBLocation)location;
/*!
@abstract
Called after an interstitial has been closed.
@param location The location for the Chartboost impression type.
@discussion Implement to be notified of when an interstitial has been closed for a given CBLocation.
"Closed" is defined as clicking the close interface for the interstitial.
*/
- (void)didCloseInterstitial:(CBLocation)location;
最佳答案
在研究了如何在Swift中正确转换Objective-C方法之后，我添加了下划线（_），将功能更改为：
func didDismissInterstitial(_ location: CBLocation) {
print("dismissing interstitial")
}
然后，XCode提示我接近委托方法，但是需要更改
location的类型，最后我得到了func didDismissInterstitial(_ location: String) {
print("dismissing interstitial")
}
我还必须使用
Chartboost.setDelegate(self)将委托设置为self，它现在可以工作。关于ios - 如何在Swift中实现Chartboost didCloseInterstitial，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/45115730/
