使用 Cloudkit 个资源作为 UIimage
Using Cloudkit Assets as a UIimage
我将图像作为资产保存在 CloudKit 中。每条记录还有其他属性。我可以收集记录并使用其他属性,但我无法在我的 ImageView 中使用该资产。我是 Swift 编程新手,因此我收到的错误没有任何意义。
let container = CKContainer.default()
let publicDB = container.publicCloudDatabase
let query1 = CKQuery(recordType: "movieArray", predicate: predicate2)
publicDB.perform(query1, inZoneWith: nil) {(results:[CKRecord]?, error:Error?) in
if error != nil {
DispatchQueue.main.async {
print("Cloud Query Error - Fetch Establishments: \(String(describing: error))")
}
return
}
for record in results! {
DispatchQueue.main.async {
let asset = record["myImageKey"] as? CKAsset
let data = NSData(contentsOf: (asset?.fileURL)!)
let image = UIImage(data: data! as Data)
print("Test")
self.detailImage.image = image
}
self.movieCast.text = record.object(forKey: "Actors") as? String
self.detailDescriptionLabel.text = record.object(forKey: "Description") as? String
let youLink = record.object(forKey: "youtubeTag") as! String
self.loadYoutube(videoID: youLink)
}
}
我得到的错误是在这一行:
let data = NSData(contentsOf: (asset?.fileURL)!)
它说:
Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1020527c4
我试图从主线程中删除它,但我收到了同样的错误。
也许问题在于 CKAsset
记录为零,但您强制 具有 fileURL
值。
尝试使用此代码段获取 CloudKit 图像
if let asset = record["myImageKey"] as? CKAsset,
let data = try? Data(contentsOf: (asset.fileURL)),
let image = UIImage(data: data)
{
self.detailImage.image = image
}
