//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 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(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 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
