Correct way to Synthesize objects?

Question

I have been synthesizing objects in my .m file this way:

@synthesize myObject;

And if I have many objects, I do it like this:

@synthesize myObject1, myObject2, myObject3;

However I see some people synthesize this way:

@synthesize myObject = _myObject;

Can somebody explain which is better way to synthesize the object?

2 is fine, 3 is just specifying the backing ivars name explicitly, so only if you need to rename the ivar do you need to use 3 — Fonix, Aug 02 '16 at 07:07

@Anbu.Karthik could u check it http://stackoverflow.com/q/38692637/2522603 — ChenSmile, Aug 02 '16 at 07:11
You could just stop using `@synthesize`, except for the usually rare cases where it's needed. — Avi, Aug 02 '16 at 07:17
Fenix, thanks. Avi, don't think we can stop synthesise since any controls not synthesised will not be detected by compiler. — GeneCode, Aug 16 '16 at 08:45

Like this : Ans 1 :

- (void)setCoolWord:(NSString *) myObject {
          _myObject = myObject;
    }

- (NSString *) myObject {
    return _myObject;
}

Hope it helped.

with Xcode 4.5 or up. The IDE write the @synthesize statement for you.

The @synthesize statement is only write the setter and getter for you.

that, _variable_name is the instant variable.

The variable_name is only a method that returns the value of _variable_name by default.

when using the variable = <Statement or value>. its calling thesetVarable_Namemethod to set the_variable_name` by default.

u r doing it by getter and setter method, which Xcode automatically does bcoz of ARC – ChenSmile Aug 02 '16 at 07:13
Xcode doesn't do anything, it's the compiler and the devices doing that. – jbehrens94 Aug 02 '16 at 07:15

in .h like this,

2.@property (nonatomic, strong) NSString *fullName;

3.do in .m where you want there written like this by using self or (_).

self.fullName (or) _fullName ;
