Can I use Objective-C blocks as properties?

Question

Is it possible to have blocks as properties using the standard property syntax? Are there any changes for ARC?

Accepted Answer

```
@property (nonatomic, copy) void (^simpleBlock)(void);
@property (nonatomic, copy) BOOL (^blockWithParamter)(NSString *input);
```

If you are going to be repeating the same block in several places use a type def

```
typedef void(^MyCompletionBlock)(BOOL success, NSError *error);
@property (nonatomic) MyCompletionBlock completion;
```
