在你说“这是一个问题的重复”之前，我已经检查过这个问题了，它告诉我的就是检查我的销售点。我所有的出口都是正确的，我不知道为什么我会犯这个错误。下面是详细的错误：

最佳答案
似乎您的应用程序的Info.plist对于NSAppTransportSecurity或其子级可能没有正确的值。
退房：MPCoreInstanceProvider.m。
“这是一个问题的重复”-下次查看堆栈跟踪时，它包含所需的所有提示：
靠近顶部的-[NSObject(NSObject) doesNotRecognizeSelector:]将引发异常（objc_exception_throw…）doesNotRecognizeSelector意味着一些代码试图调用一个不可用的方法
哪一个？再看上面：-[NSTaggedPointerString objectForKeyedSubscript:]
所以缺少的方法是objectForKeyedSubscript:这是Objective-C编译器为如下表达式生成的：myObject[@"title"]
它还告诉您调用方法的对象的类：NSTaggedPointerString，因此有些代码试图在纯字符串上使用[]，这没有多大意义
接下来要检查的是谁调用了该代码：-[MPCoreInstanceProvider appTransportSecuritySettings]是堆栈中最后一个常规代码
所以你就躲起来，找到MPCoreInstanceProvider.m
正好有一个MPCoreInstanceProvider方法
查看代码时，它会抓取一本字典appTransportSecuritySettings
然后对字典和它的值执行很多NSDictionary *atsSettingsDictionary = [NSBundle mainBundle].infoDictionary[kMoPubAppTransportSecurityDictionaryKey];操作
结论：[]中的一个在需要字典时碰到字符串。
关于swift - Swift:是否终止了NSExeption的应用程序？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/40794842/
