ios - NSException 派生类或异常名称列表？

Question

我已经通过了 Introduction to Exception Programming Topics for Cocoa .在 Throwing Exceptions 下, 显示了一个异常名称:FileNotFoundException:

NSException *e = [NSException
    exceptionWithName:@"FileNotFoundException"
               reason:@"File Not Found on System"
             userInfo:nil];

@throw e;

然而，Predefined Exceptions页面列出了大约 10 个异常，FileNotFoundException 未列出。

在哪里可以找到常见或预期异常和名称的列表？

这很奇怪，这些是我看到的在 NSExcpetion.h 中定义的唯一常量:

FOUNDATION_EXPORT NSString * const NSGenericException;
FOUNDATION_EXPORT NSString * const NSRangeException;
FOUNDATION_EXPORT NSString * const NSInvalidArgumentException;
FOUNDATION_EXPORT NSString * const NSInternalInconsistencyException;

FOUNDATION_EXPORT NSString * const NSMallocException;

FOUNDATION_EXPORT NSString * const NSObjectInaccessibleException;
FOUNDATION_EXPORT NSString * const NSObjectNotAvailableException;
FOUNDATION_EXPORT NSString * const NSDestinationInvalidException;

FOUNDATION_EXPORT NSString * const NSPortTimeoutException;
FOUNDATION_EXPORT NSString * const NSInvalidSendPortException;
FOUNDATION_EXPORT NSString * const NSInvalidReceivePortException;
FOUNDATION_EXPORT NSString * const NSPortSendException;
FOUNDATION_EXPORT NSString * const NSPortReceiveException;

FOUNDATION_EXPORT NSString * const NSOldStyleException;
