Question

I am new to iPhone development. I want to access a string variable in all the class methods, and I want to access that string globally. How can I do this?

Please help me out.

Answer 1

You can achieve that by implementing getter and setters in the delegate class.

In delegate .h file

Include UIApplication delegate

 @interface DevAppDelegate : NSObject <UIApplicationDelegate>

  NSString * currentTitle;

 - (void) setCurrentTitle:(NSString *) currentTitle;
 - (NSString *) getCurrentTitle; 

In Delegate implementation class .m

 -(void) setCurrentLink:(NSString *) storydata{
currentLink = storydata;

}

-(NSString *) getCurrentLink{
if ( currentLink == nil ) {
    currentLink = @"Display StoryLink";
}
return currentLink;
}

So the variable you to assess is set in the currentlink string by setters method and class where you want the string ,just use the getter method.

All the best
