Introduction
Welcome to the documentation for the ar_dispatch framework! Here, you will find comprehensive information on how to effectively use ar_dispatch in your projects.
Installation
- Open the terminal and navigate to the project directory.
- Run the following command to install ar_dispatch:
pod 'ar_dispatch', '~> 1.0'
Usage
Dispatch Queues
ar_dispatch provides a convenient way to perform tasks concurrently using dispatch queues.
Serial Queue
Use a serial queue when you want tasks to be executed one after another, in the order they are added.
// Create a serial queue
let serialQueue = DispatchQueue(label: "com.example.serialQueue")
// Add tasks to the serial queue
serialQueue.async {
// Task 1
}
serialQueue.async {
// Task 2
}
Concurrent Queue
Use a concurrent queue when you want tasks to be executed concurrently, without any specific order.
// Create a concurrent queue
let concurrentQueue = DispatchQueue(label: "com.example.concurrentQueue", attributes: .concurrent)
// Add tasks to the concurrent queue
concurrentQueue.async {
// Task 1
}
concurrentQueue.async {
// Task 2
}
Synchronous vs. Asynchronous
Synchronous Execution
Synchronous execution blocks the current queue until the task completes.
// Perform a synchronous task on a serial queue
serialQueue.sync {
// Task
}
Asynchronous Execution
Asynchronous execution allows the current queue to continue without waiting for the task to complete.
// Perform an asynchronous task on a concurrent queue
concurrentQueue.async {
// Task
}
Best Practices
- Choose the appropriate queue type depending on your task requirements.
- Use serial queues for tasks that need to be executed sequentially.
- Utilize concurrent queues for tasks that can be executed concurrently.
- Ensure synchronization when accessing shared resources across multiple queues.
Conclusion
Congratulations! You have successfully learned the fundamentals of using ar_dispatch in your projects. With this knowledge, you can efficiently utilize dispatch queues for concurrent and synchronized task execution.
