自己的工程以前运行ok。在xcode升级xcode6后，突然objc_msgsend报错，

例如：

 id sharedConfigCenter = objc_msgSend(networkMonitorClass,NSSelectorFromString(@"shareInstance"));

系统抛出一个语法错误：Too
many arguments to function call, expected 0, have 2。

解决方法：

 id sharedConfigCenter = objc_msgSend(networkMonitorClass,NSSelectorFromString(@"shareInstance"));

改为

      id (*typed_msgSend)(id, SEL) = (void *)objc_msgSend;
            id sharedConfigCenter  = typed_msgSend(networkMonitorClass, NSSelectorFromString(@"shareInstance"));

或者 ：

  id sharedConfigCenter = ((id (*)(id, SEL))objc_msgSend)(networkMonitorClass, NSSelectorFromString(@"shareInstance"));
