本篇内容主要讲解"如何使用线程Thread与Operation"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"如何使用线程Thread与Operation"吧!
Thread//Thread 原始方式//Thread.detachNewThread 快捷方式创建Threadfor i in 0...10 { Thread.detachNewThread{ print(i) }}/* 0 7 3 4 5 2 1 6 8 9 10 */Thread.detachNewThreadSelector//Thread.detachNewThreadSelectorclass ObjectForThread { func threadTest() { let thread = Thread(target: self, selector: #selector(threadWorker), object: nil) thread.start() print("threadTest") } @objc func threadWorker() { print("threadWorker") }}let obj = ObjectForThread()obj.threadTest()/* threadTest threadWorker */Cocoa Operation//Cocoa Operation(Operation和OperationQueue)class ObjectOperation { func test() { let operation = BlockOperation{ [weak self] in self?.threadWorker() } let queue = OperationQueue() queue.addOperation(operation) } @objc func threadWorker() { sleep(1) print("threadWorker") }}let objOperation = ObjectOperation()objOperation.test()print("after invoke test")//after invoke test//threadWorker自定义Operation//自定义Operationclass MyOperation: Operation { override func main() { sleep(1) print("MyOperation main") }}class CustomOperation { func test() { let operation = MyOperation() operation.completionBlock = { () -> Void in print("completionBlock") } let queue = OperationQueue() queue.addOperation(operation) }}let customOperation = CustomOperation()customOperation.test()print("after invoke customOperation test")//after invoke customOperation test//MyOperation main//completionBlock到此，相信大家对"如何使用线程Thread与Operation"有了更深的了解，不妨来实际操作一番吧!这里是网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习!
