Hello,

How do you read, write to a NSString for more than 1 class?

Can you give an example of what you are trying to accomplish? I can't really figure out what you are asking.

this means you wanna create a global variable....?
If yes,try declaring it in appDelegate class and can retrieve it anywhere throughout the project.

You make one instance of one class own the NSString. Make it a property of that class. Now any other class that has a reference to the first class can reference that NSString through the property of the first class. Do not be too quick to make a variable global or pseudo global unless you have to.

As the others have noted, don't just make global values.


Instead you should if required use a singleton design pattern to have a single instance of an object live during the duration of your application.
