Introduction
Welcome to the documentation for the ODDispatch library. This library provides a set of classes and functions for managing and dispatching tasks asynchronously in your Objective-C projects. It offers a convenient way to handle concurrent execution and multithreading, enhancing the performance and responsiveness of your applications.
Features
- Simplified management of tasks and queues
- Support for GCD (Grand Central Dispatch) and operation queues
- Easy task cancellation and suspension
- Dispatching tasks with custom priorities
- Error handling and recovery mechanisms
Installation
ODDispatch can be installed via Cocoapods or manually. Follow the steps below to get started:
Cocoapods Installation
To install ODDispatch using Cocoapods, add the following line to your Podfile:
pod 'ODDispatch'
Then, run the pod install
command in your terminal to install the library.
Manual Installation
If you prefer to install ODDispatch manually, follow the steps below:
- Download the ODDispatch framework from the official repository
- Drag and drop the framework into your Xcode project
- In the project settings, go to “Build Phases”
- In the “Link Binary With Libraries” section, click the “+” button and add the ODDispatch framework
Usage
After installing ODDispatch, you can start using it in your project. The following sections provide an overview of the available functionalities:
Dispatching Tasks
ODDispatch allows you to dispatch tasks asynchronously using GCD or operation queues. Depending on your requirements, you can choose the most suitable approach.
// Dispatching a block using GCD
[ODDispatch dispatchAsync:^{
// Code to be executed asynchronously
}];
// Dispatching a block using an operation queue
[ODDispatch dispatchAsyncOnQueue:backgroundQueue block:^{
// Code to be executed asynchronously
}];
Cancellation and Suspension
ODDispatch allows you to cancel or suspend tasks that are in progress. This can be useful when handling user interactions or managing resource allocation.
// Cancelling a task
[ODDispatch cancelTaskForKey:@"TaskKey"];
// Suspending a task
[ODDispatch suspendTaskForKey:@"TaskKey"];
// Resuming a suspended task
[ODDispatch resumeTaskForKey:@"TaskKey"];
Custom Priorities
ODDispatch allows you to assign custom priorities to your tasks, ensuring they are executed in the desired order. This is particularly helpful when dealing with complex workflows or performance optimizations.
[ODDispatch setPriority:ODDispatchPriorityHigh forTask:@"TaskKey"];
[ODDispatch setPriority:ODDispatchPriorityDefault forTask:@"AnotherTaskKey"];
Error Handling
ODDispatch provides mechanisms to handle errors and recover from them. This allows you to react accordingly when tasks encounter issues during execution.
// Handling errors in a dispatched task
[ODDispatch dispatchAsync:^{
@try {
// Code that may potentially throw an exception
}
@catch (NSError *error) {
// Handle the error
NSLog(@"An error occurred: %@", error.localizedDescription);
}
}];
