使用xcode和swift从照片库中选择要显示到apple watch上的图像视图的图像

import WatchKit
import Photos

PHPhotoLibrary.requestAuthorization { (status) in
    if status == .authorized {
        // 用户授权成功，可以访问照片库
    } else {
        // 用户拒绝授权或授权失败
    }
}

let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)] // 按照创建日期降序排列

let fetchResult = PHAsset.fetchAssets(with: .image, options: fetchOptions)
if let asset = fetchResult.firstObject {
    let imageManager = PHImageManager.default()
    let targetSize = CGSize(width: yourDesiredWidth, height: yourDesiredHeight)
    let requestOptions = PHImageRequestOptions()
    requestOptions.deliveryMode = .highQualityFormat
    requestOptions.resizeMode = .exact
    
    imageManager.requestImage(for: asset, targetSize: targetSize, contentMode: .aspectFill, options: requestOptions) { (image, _) in
        if let image = image {
            // 成功获取到图像
            // 将图像显示在Apple Watch的图像视图中
        } else {
            // 无法获取图像
        }
    }
}

@IBOutlet weak var imageView: WKInterfaceImage!

// 在适当的位置设置图像视图的图像
self.imageView.setImage(image)
