我最近有同样的要求,我可以通过以下步骤实现
斯威夫特:4+
步骤:1
1.Setup Your cloudKit for your app with a Developer account
2. You can take reference: https://www.raywenderlich.com/1000-cloudkit-tutorial-getting-started
第 2 步
- Add CloudKit Capabilities in your App
- Please check out the screenshot: https://prnt.sc/pdpda5
第 3 步
- 检查您的 iPhone 的云启用选项
// Return true if iCloud is enabled
func isCloudEnabled() -> Bool {
if DocumentsDirectory.iCloudDocumentsURL != nil { return true }
else { return false }
}
第 4 步
- 为本地或 iCloud 文档目录设置以下变量
struct DocumentsDirectory {
static let localDocumentsURL = FileManager.default.urls(for: FileManager.SearchPathDirectory.documentDirectory, in: .userDomainMask).last!
static let iCloudDocumentsURL = FileManager.default.url(forUbiquityContainerIdentifier: nil)?.appendingPathComponent("Documents")
}
步骤:5
下面的函数用于copyRealmFileToIcloudContainer
func uploadDatabaseToCloudDrive()
{
if(isCloudEnabled() == false)
{
self.iCloudSetupNotAvailable()
return
}
let fileManager = FileManager.default
self.checkForExistingDir()
let iCloudDocumentsURL = FileManager.default.url(forUbiquityContainerIdentifier: nil)?.appendingPathComponent("Documents", isDirectory: true)
let iCloudDocumentToCheckURL = iCloudDocumentsURL?.appendingPathComponent("\(memberId)_default.realm", isDirectory: false)
let realmArchiveURL = iCloudDocumentToCheckURL//containerURL?.appendingPathComponent("MyArchivedRealm.realm")
if(fileManager.fileExists(atPath: realmArchiveURL?.path ?? ""))
{
do
{
try fileManager.removeItem(at: realmArchiveURL!)
print("REPLACE")
let realm = try! Realm()
try! realm.writeCopy(toFile: realmArchiveURL!)
}catch
{
print("ERR")
}
}
else
{
print("Need to store ")
let realm = try! Realm()
try! realm.writeCopy(toFile: realmArchiveURL!)
}
}
步骤:6
- Once your realm file uploaded on the server , you can check this in your iPhone
- Steps
- 1.Go To Setting
- 2.Go To iCloud
- 3.Go To ManageStorage
- 4.You will see your application there
- 5.Tap on Application, you will able to see your realm file over there
步骤:7
- 确保您在 info.plist 中添加了以下行
<key>NSUbiquitousContainers</key>
<dict>
<key>iCloud.com.example.app</key>
<dict>
<key>NSUbiquitousContainerIsDocumentScopePublic</key>
<true/>
<key>NSUbiquitousContainerName</key>
<string>iCloudDemoApp</string>
<key>NSUbiquitousContainerSupportedFolderLevels</key>
<string>Any</string>
</dict>
</dict>
