ios - Assigning variable with return value -

-

i new ios, if @ following code, expect both x , y "hello"

- (void)viewdidload {     [super viewdidload];       nsstring  *x,*y;       y=    [x getstring];    }//viewdidload  -(nsstring *)getstring{       return @"hello";  }

yet, error: no visible @interface nsstring declares selector 'getstring'

i tried many things, defined getstring in .h file

your x variable type on nsstring ant there no method getstring defined there.

i believe want call [self getstring] instead:

y =  [self getstring];
