ios - Swift UIScrollView - 奇怪的填充

Question

我需要让花朵图像翻转。图像必须具有相同的高度，但自动设置宽度。我想让他们左右滚动这是我的代码:

import UIKit

class ViewController: UIViewController, UIScrollViewDelegate {

    @IBOutlet weak var scrollView: UIScrollView!

    var images = [UIImage]()

    override func viewDidLoad() {
        super.viewDidLoad()


        scrollView.delegate = self

        for i in 1...3 {
            images.append(UIImage(named: "bild-0\(i).jpg")!)
        }
        var i: CGFloat = 0
        var origin: CGFloat = 0
        let height: CGFloat = scrollView.bounds.height

        for image in images {
            let imageView = UIImageView(frame: CGRectZero)
            imageView.frame.size.height = height
            imageView.image = image
            imageView.sizeToFit()
            imageView.frame.origin.x = origin
            println(imageView.frame.size.width)
            println(imageView.frame.origin.x)
            println(imageView.frame.size.height)
            println("asd")
            origin = origin + imageView.frame.size.width
            i++
            scrollView.addSubview(imageView)
        }

        scrollView.contentSize.width = origin

        scrollView.bounces = false
        scrollView.pagingEnabled = false

    }
}

Storyboard:

问题(从顶部填充!-红色-是 UIScrollView 的背景):

图像是 765x510 300x510 等等UIScrollView 高度为 170

Answer 1

这是由滚动插入引起的:

在 Storyboard 上单击你的 ViewController 并转到文件检查器，你应该会看到这个对话框:

取消选中 Adjust Scroll View Insets。
