Grand Central Dispatch (GCD) 框架的 Swift 封装，支持方法链式调用。
您是否厌倦了这样做？
dispatch_async(dispatch_get_global_queue(QOS_CLASS_BACKGROUND, 0)) { () -> Void in
for index in 1...UInt64.max{
print(index)
}
dispatch_async(dispatch_get_main_queue(), { () -> Void in
print("Back to main thread")
})
}使用 RunKit
Run.background {
for index in 1...UInt64.max{
print(index)
}
}.main {
print("Back to main thread")
}支持的队列
Run.main {}
Run.userInteractive {}
Run.userInitiated {}
Run.utility {}
Run.background {}队列链式调用
Run.main {
print("main queue")
}.background {
print("background queue")
}.userInitiated {
print("userInitiated queue")
}.main {
print("Back to main thread")
}存储块引用以进行链式调用
let longRunningBlock = Run.background{
for index in 1...UInt64.max{
print(index)
}
}
longRunningBlock.main{
print("Back to main thread")
}
您还可以取消一个正在运行的过程
longRunningBlock.cancel()或者等待其完成
longRunningBlock.wait()
