我試圖將圖像從圖像視圖上傳到Firebase存儲。將UIImage視圖轉換爲NSURL並將其上傳到Firebase
用戶將從相冊或從相機上傳圖像到圖像視圖!我想要的是將圖像從圖像視圖上傳到Firebase存儲。
我試着遵循火力地堡文檔的例子如下:
let localFile: NSURL = ImageView.image
let metadata = FIRStorageMetadata()
metadata.contentType = "image/jpeg"
// Upload file and metadata to the object 'images/mountains.jpg'
let uploadTask = storage.child("images/DeviceImage.jpg").putFile(localFile, metadata: metadata);
// Listen for state changes, errors, and completion of the upload.
uploadTask.observeStatus(.Pause) { snapshot in
// Upload paused
}
uploadTask.observeStatus(.Resume) { snapshot in
// Upload resumed, also fires when the upload starts
}
uploadTask.observeStatus(.Progress) { snapshot in
// Upload reported progress
if let progress = snapshot.progress {
let percentComplete = 100.0 * Double(progress.completedUnitCount)/Double(progress.totalUnitCount)
}
}
uploadTask.observeStatus(.Success) { snapshot in
// Upload completed successfully
}
// Errors only occur in the "Failure" case
uploadTask.observeStatus(.Failure) { snapshot in
guard let storageError = snapshot.error else { return }
guard let errorCode = FIRStorageErrorCode(rawValue: storageError.code) else { return }
switch errorCode {
case .ObjectNotFound:
// File doesn't exist
case .Unauthorized:
// User doesn't have permission to access file
case .Cancelled:
// User canceled the upload
...
case .Unknown:
// Unknown error occurred, inspect the server response
}
}
但我不知道如何將UIImageView的轉換成NSURL。
首先確保您的硬盤上存在的圖像,然後創建一個NSURL從它的路徑。 – Roecrew
