Substring requires an "NSArray" interface size that is not constant in unstable ABI

I am trying to send information to the server using ASIHTTPRequest and setting post values ​​like this:

    for(int i = 0;i<13;i++){
  [request setPostValue:propertyValues[i] forKey:propertyKeys[i]]    
}

propertyValues ​​and propertyKeys are both NSArray objects that contain 13 elements each. When I run this, I get the error message "The subtitle requires an interface size of" NSArray, which is not a constant in an unstable ABI "

What does it mean?
