[英]How to make UIStackView scroll with UIScrollView programmatically?
我已经看到了几个使用UIScrollView
进行UIStackView
滚动的解决方案,但它们都依赖于Autolayout和IB。
有没有办法以编程方式进行?
我见过这个例子: https : //gist.github.com/twostraws/a02d4cc09fc7bc16859c
但它使用Visual Format语言,我正在使用Layout Anchor API。
布局锚点API:
view.leadingAnchor.constraintEqualToAnchor(otherview.topAnchor).active = true
您可以尝试ScrollableStackView : https : //github.com/gurhub/ScrollableStackView
示例代码(Swift)
import ScrollableStackView
var scrollable = ScrollableStackView(frame: view.frame)
view.addSubview(scrollable)
// add your views with
let rectangle = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 55))
rectangle.backgroundColor = UIColor.blue
scrollable.stackView.addArrangedSubview(rectangle)
// ...
示例代码(Objective-C)
@import ScrollableStackView
ScrollableStackView *scrollable = [[ScrollableStackView alloc] initWithFrame:self.view.frame];
scrollable.stackView.distribution = UIStackViewDistributionFillProportionally;
scrollable.stackView.alignment = UIStackViewAlignmentCenter;
scrollable.stackView.axis = UILayoutConstraintAxisVertical;
[self.view addSubview:scrollable];
UIView *rectangle = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 55)];
[rectangle setBackgroundColor:[UIColor blueColor]];
// add your views with
[scrollable.stackView addArrangedSubview:rectangle];
// ...
希望能帮助到你。
我本来想做同样的事情,偶然发现了这篇优秀的帖子。 总而言之,将UIStackView
嵌入到UIScrollView
,并通过设置UIStackView
的锚约束以匹配UIScrollView
约束来继续您想到的方向:
stackView.leadingAnchor.constraintEqualToAnchor(scrollView.leadingAnchor).active = true
stackView.trailingAnchor.constraintEqualToAnchor(scrollView.trailingAnchor).active = true
stackView.bottomAnchor.constraintEqualToAnchor(scrollView.bottomAnchor).active = true
stackView.topAnchor.constraintEqualToAnchor(scrollView.topAnchor).active = true
stackView.widthAnchor.constraintEqualToAnchor(scrollView.widthAnchor).active = true
