我一直在尝试使用共享模块 KMM 将图像上传到 aws s3 服务器。它在 Android 中运行良好,但在 iOS 中我遇到了这个问题:-Uncaught Kotlin exception: kotlin.native.IncorrectDereferenceException: illegal attempt to access non-shared
现在,尽管我对此进行了多次搜索,但我知道它与某些东西有关,frozen()
但我不确定它是什么以及如何解决这个问题。
代码 :-
actual class ClassName {
init {
ensureNeverFrozen()
}
actual fun imageUpload() {
var credentialsProvider = AWSCognitoCredentialsProvider(regionType = // Region here, identityPoolId = //identityPoolId here)
var configuration = AWSServiceConfiguration(region = // Region here, credentialsProvider = //credentialsProvider here)
AWSServiceManager.defaultServiceManager()?.defaultServiceConfiguration = configuration
val expression = AWSS3TransferUtilityUploadExpression()
// Start uploading using AWSS3TransferUtility
val awsTransferUtility = AWSS3TransferUtility.defaultS3TransferUtility()
val completionHandler: AWSS3TransferUtilityUploadCompletionHandlerBlock
completionHandler = { _: AWSS3TransferUtilityUploadTask?, error: NSError? ->
if (error == nil) {
val url = AWSS3.defaultS3().configuration.endpoint()?.URL()
val publicURL = url?.URLByAppendingPathComponent("bucketName")?.URLByAppendingPathComponent("fileName")
// Image Upload Complete
} else {
// Image Upload failure
}
}
awsTransferUtility.uploadFile(
fileUrl!!,
bucket = "bucketName",
key = "fileName",
contentType = ".image",
expression = expression,
completionHandler = completionHandler. // Error pointed on this line
)
}
}
现在,只要我调用该函数,我的应用程序就会崩溃,指向completionHandler
.
