如何使用线程Thread与Operation

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Thread for i in 0...10 {     Thread.detachNewThread{         print(i)     } } /*  0  7  3  4  5  2  1  6  8  9  10  */

Thread.detachNewThreadSelector

//Thread.detachNewThreadSelector class 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Operation class 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
