else if ([subObject conformsToProtocol:@protocol(NSCopying)]) {
// Developer should make sure these class support NSCopying satisfy deep copy.
deepCopySubObject = [subObject copy];
}
其中这一句deepCopySubObject = [subObject copy];

if(deepCopySubObject != subObject){
deepCopySubObject = [subObject mutableCopy];
}
