Sythesize vs. Multiple Arguments to a Method

[roque32]

Hi,

In chapter 7, the Synthesize and Multiple Arguments to a Method was introduced.  It is my understanding that when use @property and @synthesize, you no longer have to create the setters and getter methods.  I'm also guessing that this is thrown out the window when you are sending multiple arguments to a method.  Am I correct about this?

Thanks,
Ron

Using the

Code: (Objective-C)

 @property 

and

Code: (Objective-C)

 @synthesize 

directives to your instance variables creates the appropriate accessor methods for you. Sometimes making your own accessor methods is ideal to some situations, but most likely you'll be using these directives so that the compiler can generate the required accessor methods for you.

Also remember that you can also specify how objects are stored to your instance variables in your

Code: (Objective-C)

 @property 

directive like so:

Code: (Objective-C)

 @property (nonatomic, strong) ... 

.

This is my understanding.

A "property" is always a single value. Numerator, Denominator, Length, Width, Height... you get the idea.
So @synthesize will only set/get that single property. Makes sense. It saves a lot of work from creating setters/getters that only modify that one variable.

If you want to create a method that needs to pass 2 values, you can't synthesize this. You'd have to create  your own custom method for it, with the multiple parameters/arguments explicitly defined.
