Question

Rookie Question:
I have my ViewController.m that is getting rather big. What is the way to “off-load” some (general purpose) code to another dot-something file (let’s call it myStuff.m)?

Or to rephrase the question:

1. How I call a method from another .m file,
2. How I can access a variable and
3. How I can access an element (UIView) of another .m file.

Example:
In myStuff.m I want to do the following:

[ViewController ViewController_Method:@"bla"];
yLocal = ViewController.xRemote;
[ViewController.myText setText:@"bla-bla"];

What code do I have to add to my ViewController.m and how should the myStuff.m be set-up to do it?
What is the (easiest) way of doing it?

Answer 1

Variables

Declare public variables

@property(nonatomic,strong) VariabledatType *myVariablename;

Methods

Declare public methods

-(void)myPublicMethod:(NSString *)perameterString;

Access from another class

Let consider the variables and methods are the part of Class1

Class1Obj.myVariablename //Accessing variables;

Class1Obj.myVariablename = someValuel; //setting values to variables;   

[Class1Obj myPublicMethod:@"myString"]; //calling Methods;
