Using a BOOL property

Question

Apple recommends to declare a BOOL property this way:

@property (nonatomic, assign, getter=isWorking) BOOL working; 

As I'm using Objective-C 2.0 properties and dot notation, I access this property using self.working. I know that I could also use [self isWorking] — but I don't have to.

So, as I'm using dot notation everywhere, why should I define an extra property? Would it be okay to simply write

@property (nonatomic, assign) BOOL working; 

Or do I have any benefits writing getter=isWorking in my case (usage of dot notation)?

Thanks!

Answer 1

Apple simply recommends declaring an isX getter for stylistic purposes. It doesn't matter whether you customize the getter name or not, as long as you use the dot notation or message notation with the correct name. If you're going to use the dot notation it makes no difference, you still access it by the property name:

@property (nonatomic, assign) BOOL working;  [self setWorking:YES];         // Or self.working = YES; BOOL working = [self working]; // Or = self.working; 

Or

@property (nonatomic, assign, getter=isWorking) BOOL working;  [self setWorking:YES];           // Or self.working = YES;, same as above BOOL working = [self isWorking]; // Or = self.working;, also same as above 

Answer 2

Apple recommends for stylistic purposes.If you write this code:

@property (nonatomic,assign) BOOL working; 

Then you can not use [object isWorking].
It will show an error. But if you use below code means

@property (assign,getter=isWorking) BOOL working; 

So you can use [object isWorking] .
