Objective-c anonymous property coding style

Question

If I have an interface defined like

@interface MyClass
@property (nonatomic, copy, readonly) NSString *myString;
@end

so that myString is externally visible but can't be written, what would be the preferred coding style for redeclaring the property in the implementation? Would it be (a)

@property (nonatomic, copy) NSString *myString;

or (b)

@property (nonatomic, copy, readwrite) NSString *myString;

(I know that these two are exactly the same, this is a question purely about coding style!)

• Jack: Afaik just mentioning (readwrite) in the implementation will do.

Answer 1

The preferred coding style would be (b) according to all style guides that I've seen (e.g. https://github.com/objc-zen/objc-zen-book#property-declaration). They recommend explicitly specify readwrite attribute (for the sake of clarity, I guess).

• deanWombourne: I disagree - this answers my question perfectly. I don't know why it's been down-voted!
