typeof 编译错误

__weak typeof(self) wSelf = self报错：- A parameter list without types is only allowed in a function definition. A corresponding warning tells me that __weak only applies to Objective-C object or block pointer types; type here is 'int'

在phone gap项目集成过程中，__weak typeof(self) wSelf = self;声明都报了错，分析原因可能是编译器识别不了typeof关键字

解决办法如下：

Xcode－> Build Settings-> C Language Dialect修改配置，C99改为GNU99，C99是不包含typeof的
