How can I access variables from another class?

Question

There is probably a very simple solution for this but I can\'t get it working.

I have got multiple classes in my Cocoa file. In one of the classes class1

Answer 1

try making a file that holds your variables that need to be accessed throughout the app.

extern NSString *stringVariable;

@interface GlobalVariables

@property (retain, nonatomic) NSString *stringVariable;    

@end

and in the GlobalVariables.m file add

#import "GlobalVariables.h"

@implements GlobalVariables

@synthesize stringVariable;

NSString *stringVariable;

@end

And then as long as you import GlobalVariables.h into which ever .m files you need to access that variable in you can assign and access anywhere throughout your program.

EDIT

My answer that I have given above is differently not the way I would go about doing this now. It would be more like

@interface MyClass

@property (nonatomic, strong) NSString *myVariable;

@end

then in the .m file

@implementation MyClass

@sythesize = myVariable = _myVariable; // Not that we need to do this anymore

@end

Then in another class in some method I would have

// .....
MyClass *myClass = [[MyClass alloc] init];
[myClass setMyVariable:@"My String to go in my variable"];
// .....
