+// "public" interface: where bar is declared readonly, copy
+@interface Foo : NSObject {
+ NSString *bar;
+}
+@property(readonly, copy) NSString *bar;
+@end
+
+// "private" interface: where bar is redeclared readwrite
+@interface Foo ()
+@property(readwrite) NSString *bar;

+
+ The preceding property redeclaration generates the following warnings:
+
+ warning: no 'assign', 'retain', or 'copy' attribute is specified - 'assign' is assumed
+ warning: 'assign' attribute (default) not appropriate for non-gc object property 'bar'
+ warning: property 'bar' attribute in 'Foo' class continuation does not match class 'Foo' property
+
+ In order to make the warnings go away the copy attribute must be explicitly carried over to the redeclaration:
+
+ @property(readwrite, copy) NSString *bar;
+
+ So here we either have a compiler bug or a documentation bug, because the documentation states:
+
+ "You can re-declare properties in a subclass, and you can repeat properties' attributes in whole or in part"
+ "The same holds true for properties declared in a category"
+ "the property's attributes must only be repeated in whole or part"
+
+ Which would imply that explicitly repeating the "copy" attribute should not be necessary.
