-(void) loadView with NSMutableArray

- (void)loadView 
{
    [super loadView];
    arrayOfImages = [[NSMutableArray alloc]initWithObjects:@"11.jpg",@"22.jpg",@"33.jpg", nil];       
    UIImageView *awesomeView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    [awesomeView setImage :[UIImage imageNamed:[arrayOfImages objectAtIndex:0]]];
    awesomeView.contentMode = UIViewContentModeScaleAspectFit;
    [self.view addSubview:awesomeView]; 
    NSLog(@"%@",[arrayOfImages objectAtIndex:0]);
}

When I put the NSMutableArray in -(void)viewDidLoad, UIImageView displays nothing and NSLog shows NULL. Why is that?

ps. NSMutableArray worked perfectly in -(void)loadView. I've declared NSMutableArray *arrayOfImage in @interface .h file

Solution

  • The only way that the given could would output "NULL" in this situation is that arrayOfImages is NULL by itself.

    This is only possible if arrayOfImages is declared as a weak variable.

    But as @maddy pointed out, your code is all wrong: Don't call super, but assign self.view. Or use viedDidLoad instead (probably what you want here).
