Hopper - no CFG leaving procedure at this address

Question

Where is it that, when I am at a procedure with a lot of db, hopper will not show the control flow graph.

1. How do I make the db change to a regular assembly symbol like mov,add,ret etc.
2. What cause the db not to show the control flow graph

             aWindow_2f81:        // aWindow
00002f81         db         "window", 0                                         ; DATA XREF=0x3470
             aTuiwindown:
00002f88         db         "T@\"UIWindow\",&,N", 0
             aTuiwindownvwin:
00002f99         db         "T@\"UIWindow\",&,N,V_window", 0                    ; DATA XREF=0x3470
             aHelloWorld:
00002fb3         db         "Hello World!", 0                                   ; DATA XREF=cfstring_Hello_World_
             aLabel_2fc0:        // aLabel
00002fc0         db         "label", 0                                          ; DATA XREF=0x3540
             aTuilabelnvlabe:
00002fc6         db         "T@\"UILabel\",&,N,V_label", 0                      ; DATA XREF=0x3540
00002fde         db  0x00 ; '.'
00002fdf         db  0x00 ; '.'

This is the corresponding ViewController.m code

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)buttonHello:(id)sender {
    
    _label.text = @"Hello World!";  
}
@end

As @blabb mentioned, this is a series of null terminated strings, it isn't code. They may be in the code segment but that doesn't make them instructions, and telling Hopper to treat them as code will result in rubbish.
