在Objective-C枚举中查找整数值

在Objective-C中是否可以查看int值是否在特定的枚举中？例如,在这个枚举中：

enum  {
  ValidationLoginFailed         = 2000,ValidationSessionTokenExpired = 2001,ValidationSessionTokenInvalid = 2002,ValidationEmailNotFound       = 2003  
}; 
typedef int ValidationStatusCodes;

是否可以查看ValidationStatusCodes枚举中是否有任意整数值？

[ValidationStatusCodes contains:intResponseCode]

或至少

[self intIsInRangeofEnum:ValidationStatusCodes forValue:intResponseCode]

解决方法

没有比做更简单的方法了

(ValidationLoginFailed == intResponseCode ||
ValidationSessionTokenExpired == intResponseCode ||
ValidationSessionTokenInvalid == intResponseCode ||
ValidationEmailNotFound == intResponseCode)

通常,C对于执行动态事物或反映类型并不是很有帮助,而枚举是C功能.
