Question

i need to define an array as global variable that i can use it all over my code the array must have a data for 10 random number that must be fixed all over the code what i did it the following but with no luck
in the .h file after the @interface i put this line

NSMutableArray *globalarray;

and in the .m file i put this after the @implemention file

- (void)glo {
if (!globalarray) {
 globalarray= [NSMutableArray  globalarray];
    for (int x = 0; x < 10; x++) {
        [globalarray addObject:[NSNumber numberWithInt: arc4random()%200]];
    }}}

and on the same .m file i called the array in NSLOG as follows

-(IBAction)click_one:(id)sender{


    NSLog(@"%@",globalarray);}



-(IBAction)click_two:(id)sender{


    NSLog(@"%@",globalarray);}

the NSLOG returns null in the console any help is highly apprectaied thanks

This line:

globalarray= [NSMutableArray  globalarray];

assumes that there’s some method on NSMutableArray called “globalarray”. There isn’t. You want:

globalarray = [[NSMutableArray alloc] init];
