iOS - Is it better to use getter/setter methods directly or properties

Question

I know that properties kind of encapsulate getter and setter methods. So whenever we say myObject.property1 we actually cause to call [myObject property1]. From Apple documentation, Stanford iOS Courses and sample codes I can see that the usage of properties are encouraged. I aggree that using properties make a code look better and more understandable but what about performance? If I write a huge application will using properties have a noticableimpact on performance? Do professionals generally prefer direct setter and getter methods or properties?

Answer 1

There is no difference in performance when you use the bracket notation ([myObject property1]) or the . notation (myObject.property1).

This is more of a coding style than any thing else, so use the notation you are comfortable with or the same notation as your team if you don't work alone.

Answer 2

Properties are probably better because they automatically generate the methods for you and when you synthesize them you can do it like this:

@synthesize property = _property

To avoid any confusion

Also you can choose different functions/methods like:

           (nonatomic, retain) // or (readonly) etc.

It also handles the memory better
