Welcome to the documentation for TOFileSystemObserver, a lightweight Objective-C library that provides an easy way to observe changes in the file system on iOS.
Installation
TOFileSystemObserver can be installed using CocoaPods. Simply add the following line to your Podfile:
pod 'TOFileSystemObserver'
Then, run the command pod install
in your project directory.
Usage
To start observing file system changes, follow these steps:
Step 1: Import TOFileSystemObserver
Add the following import statement to the top of your code file:
import TOFileSystemObserver
Step 2: Create an Observer Instance
Create an instance of TOFileSystemObserver
to start observing file system changes:
// Initialize the observer
let observer = TOFileSystemObserver()
Step 3: Start Observing
Start observing file system changes by calling the startObserving()
method:
// Start observing
observer.startObserving()
Step 4: Handle File System Changes
To handle file system changes, implement the TOFileSystemObserverDelegate
protocol in your class and set it as the observer’s delegate:
// Set the observer's delegate
observer.delegate = self
// Implement the delegate methods
func fileSystemObserver(_ observer: TOFileSystemObserver, didObserveFileSystemChangeWithNotifications notifications: [Notification]) {
// Handle file system changes here
}
Step 5: Stop Observing
To stop observing file system changes, call the stopObserving()
method:
observer.stopObserving()
Example
Here’s an example that demonstrates how to use TOFileSystemObserver:
// Import TOFileSystemObserver
import TOFileSystemObserver
// Create your file observer class and conform to TOFileSystemObserverDelegate
class FileObserver: TOFileSystemObserverDelegate {
// Create an instance of TOFileSystemObserver
let observer = TOFileSystemObserver()
// Start observing file system changes
func startObserving() {
observer.delegate = self
observer.startObserving()
}
// Stop observing file system changes
func stopObserving() {
observer.stopObserving()
}
// Implement the delegate method to handle file system changes
func fileSystemObserver(_ observer: TOFileSystemObserver, didObserveFileSystemChangeWithNotifications notifications: [Notification]) {
// Handle file system changes here
for notification in notifications {
// Process each notification
}
}
}
// Example usage
let fileObserver = FileObserver()
fileObserver.startObserving()
Conclusion
TOFileSystemObserver provides a convenient way to observe changes in the file system on iOS. By following the steps outlined in this documentation, you’ll be able to easily integrate this library into your project and handle file system changes effectively.
