Question

我在Main.storyboard上面有一个视频帧，我把ScrollView和TextView放在一起，现在我的问题是ScrollView在所有设备上的位置不同。

例如，在iPhone 7 Plus中它处于正确的位置，但在iPhone SE中它的iPad却不同。

这是我的ViewController.swift代码：

import UIKit
import AVFoundation
import AVKit

class ViewController: UIViewController {

    let playerController = AVPlayerViewController()
    var player:AVPlayer?

    @IBOutlet weak var textView: UITextView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let videoString:String? = Bundle.main.path(forResource: "m9", ofType: ".mov")

        playerController.player = player
        self.addChildViewController(playerController)
        let screenSize = UIScreen.main.bounds.size
        let videoFrame = CGRect(x: 0, y: 30, width: screenSize.width, height: (screenSize.width * 9) / 16 )
        playerController.view.frame = videoFrame
        self.view.addSubview(playerController.view)
        player?.play()

然后我尝试将ScrollView链接到视频帧：

let frame1 = CGRect(x: 0, y:  350 + videoFrame.height , width: screenSize.width, height: screenSize.height)

textView.frame = frame1

只需制作滚动视图的插座并将其框架设置为：

Checkbox check1 = new Checkbox(getApplicationContext());
check1.setLayoutParams(new ActionBar.LayoutParams(LinearLayoutCompat.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
check1.setId(fieldNo);
check1.setTextColor(Color.BLACK);
check1.setGravity(Gravity.RIGHT);
check1.setText(formField.get(fieldNo));

但是，最好使用autolayout而不是设置帧。这是链接。

此代码在滚动视图中完美运行。简单的scrollview添加avplayerviewcontoller然后不要刷卡，所以替换此代码......

 let url = // whatever
 let player = AVPlayer(URL:url)
 let av = AVPlayerViewController()
 av.player = player
 av.view.frame = // whatever
 self.addChildViewController(av)
 self.view.addSubview(av.view)
 av.didMoveToParentViewController(self)
