我试图隐藏滚动视图，但它没有隐藏

Question

好吧，这是一个令人尴尬的简单问题，但我就是无法让它正常工作！我有两个 uiscrollviews，我已经将它们连接到 IB 中的任何地方。在 viewDidLoad 上，我只希望第一个可见。所以我创建了两个滚动视图：

    [scrollView1 setBackgroundColor:[UIColor blackColor]];
[scrollView1 setCanCancelContentTouches:NO];
scrollView1.clipsToBounds = NO;    // default is NO, we want to restrict drawing within our scrollview
scrollView1.indicatorStyle = UIScrollViewIndicatorStyleWhite;

scrollView1.minimumZoomScale = 1;
scrollView1.maximumZoomScale = 5;
scrollView1.delegate = self;
[scrollView1 setScrollEnabled:YES];

imageView31 = [[UIImageView alloc] initWithImage:firstImage];

[scrollView1 addSubview:imageView31];
//[scrollView1 setFrame:CGRectMake(0, 0, 1024, 660)];


[scrollView2 setBackgroundColor:[UIColor blackColor]];
[scrollView2 setCanCancelContentTouches:NO];
scrollView2.clipsToBounds = NO;    // default is NO, we want to restrict drawing within our scrollview
scrollView2.indicatorStyle = UIScrollViewIndicatorStyleWhite;

scrollView2.minimumZoomScale = 1;
scrollView2.maximumZoomScale = 5;
scrollView2.delegate = self;
[scrollView2 setScrollEnabled:YES];

imageView32 = [[UIImageView alloc] initWithImage:firstImage];

[scrollView2 addSubview:imageView32];

然后为了只显示第一个滚动视图，我这样做了：

scrollView2.hidden == YES;

但是当我加载时它仍然在那里！

有人知道发生了什么事吗？

Answer 1

试试这个：

scrollView2.hidden = YES;  // one equals sign

双等于是在进行比较，而不是赋值，而且它基本上没有完成任何事情。
