You can also disable the ARC for the RegexKitLite only by adding a flag:
select the project -> YOUR Target -> on the Tab the "Build Phases" and open the "Compile Sources" and add for "RegexKitLite.m" the flag "-fno-objc-arc".
我還是不理解，不過成功了就行。。。
RegexKitLite下載導入項目之後編譯提示錯誤。錯誤如下

解決辦法：
In project setting search "other" at Other Linker Flags put the word "-licucore".
編譯設置的Other Linker Flags中添加“－licucore”
