滚动视图不在 xib 文件中滚动

问题描述

我是 iphone 开发新手.我在我的应用程序中添加了滚动视图，并在滚动视图中以图形方式添加了 10 个按钮.但是当我运行滚动视图时没有滚动

I am new in iphone development.. I have added the scrollview in my app and added 10 buttons graphically inside the scrollview. but when I run the scrollview is not scrolling

我的代码如下

- (void)viewDidLoad
{
    [super viewDidLoad];

    [scrollview setContentSize:CGSizeMake(1500,50)];

    [scrollview setBackgroundColor:[UIColor blackColor]];
    [self.view addSubview:scrollview];
}

推荐答案

看来你是在xib中使用scrollview.因此，您需要从代码中删除 [self.view addSubview:scrollview]; 并且您可以直接在 xib 中设置该滚动视图的属性，除了 setContentSize(您需要在 .m 文件中设置).

It looks like you are taking scrollview in xib. So, you need to remove [self.view addSubview:scrollview]; from your code and you can directly set properties of that scrollview in xib except setContentSize(that you need to set in .m file).

或者如果你想手动创建scrollView，从xib中移除并使用这个:

Or if you want to create scrollView manually, remove from xib and use this:

UIScrollView * content = [[UIScrollView alloc] initWithFrame:self.view.bounds];
[content setContentSize:CGSizeMake(width, height)];
//Here you can add those buttons to content view
[self.view addSubView:content];
