UIScrollView 不会滚动，即使在内容大小设置后

问题描述

我的 UIScrollView 是一个大约 4500 像素的水平视图，用户需要水平滚动才能查看内容.

我设置如下:

- (void)viewDidLoad{[超级视图DidLoad];sview.frame = CGRectMake(0, 0, 568, 320);sview.contentSize = CGSizeMake(4500, 320);[sview setScrollEnabled:YES];}

然而滚动视图什么也没做.有什么明显的我错过了吗?我已经尝试过网络上的每个教程.

我遇到了类似的问题.我做了以下修改，scrollView 开始为我滚动:

1. 选择以检查 UIScrollView 的水平反弹"属性在西布.
2. 将代码后面的代码移动到 viewDidAppear 而不是viewDidLoad:

<块引用>

-(void) viewDidAppear:(BOOL)animated{[超级 viewDidAppear:动画];sview.frame = CGRectMake(0, 0, 568, 320);sview.contentSize = CGSizeMake(4500, 320);[sview setScrollEnabled:YES];}

我认为这应该对你有所帮助.

My UIScrollView is a ~4500px horizontal view that the user needs to scroll horizontally through to view the content.

I have set it up as follows:

- (void)viewDidLoad
{

    [super viewDidLoad];

    sview.frame = CGRectMake(0, 0, 568, 320);
    sview.contentSize = CGSizeMake(4500, 320);
    [sview setScrollEnabled:YES];
}      

Yet the scroll view does nothing. Is there something obvious I missed? i've tried literally every tutorial on the web.

I got similar issue. I did following modifications and the scrollView started scrolling for me:

1. Select to check the 'Bounce Horizontally' property for UIScrollView in xib.
2. Move the code following code to viewDidAppear instead of viewDidLoad:

-(void) viewDidAppear:(BOOL)animated
{

    [super viewDidAppear:animated];
    sview.frame = CGRectMake(0, 0, 568, 320);
    sview.contentSize = CGSizeMake(4500, 320);
    [sview setScrollEnabled:YES];

}

I think this should help you.
