edit:/for ivars/

- (nsmutablearray *)getallpropertyofclass:(class)aclass {     nsmutablearray *marray=[nsmutablearray new];     unsigned int outcount;     ivar *ivars = class_copyivarlist([aclass class], &outcount); //class_copypropertylist([aclass class], &outcount);      for(unsigned int = 0; < outcount; i++) {         ivar ivar = ivars[i];         const char *propname = ivar_getname(ivar);         if(propname) {             nsstring *propertyname = [nsstring stringwithutf8string:propname];             marray[marray.count]=propertyname;         }     }     free(ivars);     return marray; }
