我从Ryan Nystrom 的 github下载了这段代码；它是Dave Child 的 github上 PHP 文本统计项目的 Objective C 端口。有些东西我不认为是Objective C，但我是一个新手程序员，所以我想通过stackoverflow运行它，看看在我与程序员联系之前我是否犯了一些明显的错误。

我的问题是音节计数方法中有一个单词的 NSDictionary 是异常的，但是当我使用它来计算包含这些单词的文本中的音节时，它们不会被视为异常。例如，字典包含“十二”这个词，并指出它应该算作一个音节，但是当我分析“十二”这个词时，它会出现两个音节。

现在还有一个结尾/模式列表，需要计为一个音节，否则可能会计为两个音节（-cious、-cial 等）。当我在该列表中添加“十二”时，它被计为一个音节。因此，该列表似乎运行良好。这只是似乎不起作用的异常字典。

我错过了一些非常明显的东西吗？或者这是与编码员联系并让他知道的情况？

在此先感谢您的帮助。

该方法的其余部分使用字符串的处理形式——即，在去除空格和小写之后——但是exceptions字典查找使用的是原始形式，所以除非你的字符串是精确 的，@"twelve"而不是@"Twelve"，，它不会'在那里找不到。@" twelve "@"twelve\t"

使固定：

--- a/NSString+RNTextStatistics.m
+++ b/NSString+RNTextStatistics.m
@@ -204,7 +204,7 @@
     @"wandered" : @2
     };
     // if one of the preceding words, return special case value
-    NSNumber *caught = exceptions[self];
+    NSNumber *caught = exceptions[lowercase];
     if (caught) {
         return caught.integerValue;
     }

您可能应该将此作为错误提交给作者。
