无法在滚动视图中滚动。

This is my view layout in storybaord:

这是我在storybaord的视图布局:

My Scroll view frame is set to be 320x568, and in my view controller I have set

我的滚动视图框架设置为320x568，在我的视图控制器中设置。

self.scrollView.scrollEnabled = YES;
[self.scrollView setContentSize:CGSizeMake(320,1000)];//obviously content is larger than frame

However, the scroll still doesn't work. So I enabled vertical bounce, and found that every time when I drag down it just bounces back to original position. Can anyone help me fix this issue?

然而，卷轴仍然不能工作。所以我启用了垂直弹跳，并且发现每次当我向下拖动时它会反弹回原来的位置。有人能帮我解决这个问题吗?

4 个解决方案

#1

First turn off AutoLayout - click on scrollview and uncheck Use AutoLayout

首先关闭自动播放-单击scrollview并取消使用AutoLayout。

In your .h file add the UIScrollViewDelegate for example:

在您的.h文件中添加UIScrollViewDelegate:

@interface myViewController : UIViewController <UIScrollViewDelegate>

@interface myViewController: UIViewController 。

In your .m file in viewDidLoad set

在viewDidLoad集中的.m文件中。

self.myScrollView.delegate = self;
self.myscrollView.scrollEnabled = YES;
self.myscrollView.contentSize=CGSizeMake(320.0, 1094.0);

keep Bounces ON and set scrollview frame 320 X 960

保持弹跳和设置scrollview框架320 X 960。

#2

In your .h file add the UIScrollViewDelegate for example:

在您的.h文件中添加UIScrollViewDelegate:

@interface myViewController : UIViewController <UIScrollViewDelegate>

In your .m file in viewDidLoad set

在viewDidLoad集中的.m文件中。

self.myScrollView.delegate = self;

If you have one subview in your scrollview, as you do, the scrollview will scroll to the dimensions of that view. See the answer here for details.

如果您的scrollview中有一个子视图，那么scrollview将滚动到该视图的维度。详见这里的答案。

view.userInteractionEnabled = YES

视图。userInteractionEnabled = YES
