Question

Suppose I have

@interface A : NSObject
@property (nonatomic, strong) NSMutableArray *array;
@end

Later on in another class B, I want to access that array, to check how many items are in it. I can do one of two things in B (a is an instance of A):

Option 1

[a.array count]

Option 2

[[a array] count];

Which option is the best way to do this? Is option 2 the right way to access the array when using [a array] as the getter method?

Answer 1

both are the same if you have synthesized the array. in first one you just call the property and in 2nd one you are calling the getter method which was generated by @synthesize action.

and sure the 2nd option is the right way as @synthesize makes two methods

1- getter that is same as the property name
2- setter that is add set with property name at start with first letter captial like setArray.
