将视图添加到我的UIScrollView末尾时出现问题

Question

我有一个包含大量视图的UIScrollView：

for(NSDictionary* deal in deals)
    {
        [items addObject:deal];

        DealViewController *dvc = [[DealViewController alloc] initWithNibName:@"DealViewController" bundle:nil];
        [dvc setNavigationController:[self navigationController]];
        UIView *dealView = [dvc view];
        [dealViewControllers addObject:dvc];

        //setup scrollView
        frame.origin.x = frame.size.width * i; 
        NSLog(@"Frame origin: %f", frame.origin.x);
        [dealView setFrame:frame];
        [scrollView addSubview:dealView];
        i++;
        [dvc displayDeal:deal];
    }

我想在scrollview的最后添加一个视图，如下所示：

SignUpViewController* signUpView = [[SignUpViewController alloc] initWithNibName:@"SignUpViewController" bundle:nil];
[scrollView insertSubview:signUpView.view atIndex:[items count]];

signUpView出现在UIScrollView的开头。如何将其添加到最后？

Answer 1

frame.origin.x = frame.size.width * i;
[signUpView setFrame:frame];

你没有告诉它在哪里画画。

Answer 2

尝试使用

[scrollView insertSubview:signUpView.view atIndex:[items count] - 1];
