scrollview不在xib文件滚动

问题描述

我是iphone开发的新手。我在我的应用程序中添加了scrollview，并在scrollview中以图形方式添加了10个按钮。但当我运行时，滚动视图不滚动

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

看起来你正在服用在xib中的scrollview。所以，你需要从你的代码中删除 [self.view addSubview：scrollview]; ，你可以直接在xib中设置该scrollview的属性，除了setContentSize（你需要设置）在.m文件中）。

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，请从xib中删除并使用它：

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];
