NSOperation subclass for async block.
- Both compatible with Swift and Objective-C.
- Light-weight. (4KB source code. Oh my god.)
- Short-hand method extension
NSOperationQueue.
Swift
import AsyncBlockOperation
let operation = AsyncBlockOperation { op in
doSomeAsyncTaskWithCompletionBlock {
op.complete() // complete operation
}
}
queue.addOperation(operation)Objective-C
#import <AsyncBlockOperation/AsyncBlockOperation.h>
AsyncBlockOperation *operation = [AsyncBlockOperation blockOperationWithBlock:^(AsyncBlockOperation *op) {
[self doSomeAsyncTaskWithCompletionBlock:^{
[op complete]; // complete operation
}];
}];
[queue addOperation:operation];As NSBlockOperation does, AsyncBlockOperation supports NSOperationQueue extension to add async block operations quickly.
Swift
queue.addOperationWithAsyncBlock { op in
op.complete()
}Objective-C
[queue addOperationWithAsyncBlock:^(AsyncBlockOperation *op) {
[op complete];
}];Wanna get callback after all operations are done? Consider using NSOperationQueue+CompletionBlock which provides completionHandler for NSOperationQueue.
For example:
let queue = NSOperationQueue()
queue.completionHandler = {
println("All images are loaded!")
}
queue.addOperationWithAsyncBlock { op in
loadImage(imageURL1) { image in
image.append(image)
op.complete()
}
}
queue.addOperationWithAsyncBlock { op in
loadImage(imageURL2) { image in
image.append(image)
op.complete()
}
}I recommend you to use CocoaPods, a dependency manager for Cocoa.
