请问怎么将unsigned short数组转换成NSString？

- (id)initWithCharactersNoCopy:(unichar *)characters length:(NSUInteger)length freeWhenDone:(BOOL)freeBuffer;    /* "NoCopy" is a hint */
- (id)initWithCharacters:(const unichar *)characters length:(NSUInteger)length;
- (id)initWithUTF8String:(const char *)nullTerminatedCString;

------解决方案--------------------

unsigned short  跟 unichar应该可以互换等同使用。
