You can try instead

- (void)viewDidLoad
{
    NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"figo",@"messi",@"totti",@"ronaldo",@"pirlo", nil];
    [super viewDidLoad];

    [text setText:[array componentsJoinedByString:@"\n"];
}

or if you want them all in a line, separated by whatever character, you can just replace @"\n" and use yours. @", " would be ok, but also @" "

NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"figo",@"messi",@"totti",@"ronaldo",@"pirlo", nil];
    for (NSString *str in array) {
        tvText.text = [NSString stringWithFormat:@"%@\n%@", tvText.text,str];
    }

To print in same line use following code.. tvText.text = [NSString stringWithFormat:@"%@%@", tvText.text,str];

you can also do this

 NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"figo",@"messi",@"totti",@"ronaldo",@"pirlo", nil];
    NSMutableString* theText = [NSMutableString new];
    for (NSString* line in array)
    {
    [theText appendFormat: @"%@\n", line];
    }


[text setText:theText];

just change the NSString to NSMutableString
