UIView
does not conform to NSCopying
, but it does conform to NSCoding
:
another.imageView = [NSKeyedUnarchiver unarchiveObjectWithData:
[NSKeyedArchiver archivedDataWithRootObject:self.imageView]];
This serializes and then deserializes the object, which is the standard way to perform a deep copy in ObjC.
EDIT: See https://stackoverflow.com/a/13664732/97337 for an example of a common -clone
category method that uses this.
