make this string variable global. then u can use this.

In your firstclass you need to import the second class like

#import "second.h"

and then you need to make an object of it like

Second *obj=[[Second alloc]init];

and then you can check the string value using

if{  [obj.mystr isEqualToString @"sarab"]}{
//then do something here
}

but all this work only if you define the string first and then compare it ..

hope this helps...

Declare your string in the appdelegate file and access it where ever you want using :

 appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
        if([appDelegate.<yourString> isEqualToString:@"<compareString>"]){
NSLog(@"appDelegate.<yourString> = %@",appDelegate.<yourString>);
           }
