Simple and Elegant Timer

中文介绍：打造一个优雅的Timer

Compare with NSTimer

• No retain cycle
• Decouple with RunLoop
• Support GCD queue
• Support dynamically changing interval
• Support closure syntax

Usage

single timer

//We need to maintain a strong reference to SwiftTimer. When self dealloc, timer will dealloc too. self.timer =SwiftTimer(interval:.seconds(2)){print("fire")}self.timer.start()

repeatic timer

timer =SwiftTimer.repeaticTimer(interval:.seconds(1)){print("fire")}
timer.start()

dynamically changing interval

timer =SwiftTimer.repeaticTimer(interval:.seconds(5)){ timer inprint("doSomething")}
timer.start() // print doSomething every 5 seconds
func speedUp(timer:SwiftTimer){
timer.rescheduleRepeating(interval:.seconds(1))}speedUp(timer) // print doSomething every 1 second 

throttle

The closure will be called after interval you specified. It is invalid to call again in the interval.

SwiftTimer.throttle(interval:.seconds(0.5), identifier:"refresh"){refresh();
}

debounce

The closure will be called after interval you specified. Calling again in the interval cancels the previous call.

SwiftTimer.debounce(interval:.seconds(0.5), identifier:"search"){search(inputText)}

count down timer

timer =SwiftCountDownTimer(interval:.fromSeconds(0.1), times:10){ timer , leftTimes in
label.text ="\(leftTimes)"}
timer.start()
