In this documentation, you will find detailed information on file operations using the FileOperations framework. This framework provides a set of classes and methods that allow you to perform various operations on files in your iOS and Mac applications.
Installation
To include the FileOperations framework in your project using CocoaPods, add the following line to your Podfile:
“`ruby
pod ‘FileOperations’
“`
If you prefer to install the framework manually, follow these steps:
- Download the latest version of the framework from the FileOperations GitHub repository.
- Unzip the downloaded file.
- In Xcode, select your project and go to the “General” tab of your target.
- Drag and drop the FileOperations.framework folder into the “Frameworks, Libraries, and Embedded Content” section.
- Make sure the framework is added to your target’s “Frameworks, Libraries, and Embedded Content” section.
Getting Started
To use the FileOperations framework in your code, make sure to import it:
“`swift
import FileOperations
“`
Before performing file operations, it is recommended to create an OperationQueue
instance to manage the execution of your operations:
“`swift
let operationQueue = OperationQueue()
“`
If your operations have dependencies, you can add them using the addDependency(_:)
method. This ensures that an operation is not executed until its dependencies have finished:
“`swift
operation1.addDependency(operation2)
“`
To execute an operation, add it to the operation queue:
“`swift
operationQueue.addOperation(operation)
“`
Operations
File Copy Operation
The FileCopyOperation allows you to copy a file from one location to another. It provides methods to set the source and destination paths:
“`swift
let fileCopyOperation = FileCopyOperation()
fileCopyOperation.sourcePath = “path/to/source/file”
fileCopyOperation.destinationPath = “path/to/destination/file”
“`
You can track the progress of the copy operation by implementing the FileCopyOperationDelegate
protocol:
“`swift
class MyDelegate: FileCopyOperationDelegate {
func fileCopyOperation(_ operation: FileCopyOperation, didUpdateProgress progress: Float) {
// Update your UI with the current progress
}
}
“`
To start the copy operation, add it to the operation queue:
“`swift
operationQueue.addOperation(fileCopyOperation)
“`
File Move Operation
The FileMoveOperation allows you to move a file from one location to another. It provides methods to set the source and destination paths:
“`swift
let fileMoveOperation = FileMoveOperation()
fileMoveOperation.sourcePath = “path/to/source/file”
fileMoveOperation.destinationPath = “path/to/destination/file”
“`
To start the move operation, add it to the operation queue:
“`swift
operationQueue.addOperation(fileMoveOperation)
“`
File Delete Operation
The FileDeleteOperation allows you to delete a file at a given path:
“`swift
let fileDeleteOperation = FileDeleteOperation()
fileDeleteOperation.filePath = “path/to/file”
“`
To start the delete operation, add it to the operation queue:
“`swift
operationQueue.addOperation(fileDeleteOperation)
“`
File Existence Operation
The FileExistenceOperation allows you to check if a file exists at a given path:
“`swift
let fileExistenceOperation = FileExistenceOperation()
fileExistenceOperation.filePath = “path/to/file”
“`
To get the result of the existence check, implement the FileExistenceOperationDelegate
protocol:
“`swift
class MyDelegate: FileExistenceOperationDelegate {
func fileExistenceOperation(_ operation: FileExistenceOperation, didCompleteWithResult result: Bool) {
// Handle the result (true if file exists, false otherwise)
}
}
“`
To start the existence check operation, add it to the operation queue:
“`swift
operationQueue.addOperation(fileExistenceOperation)
“`
Conclusion
In this documentation, we covered the various file operations provided by the FileOperations framework. You learned how to perform file copy, move, delete, and existence check operations using the framework’s classes.
