Use of Swift Timer--(I test)

Need to use the timer in the project

Here I Baidu a bit

Usage is about the same as OC

The test succeeds, and there's not much change in the code below.

Timer

private Var timer:timer!

Enable timers to control the Getnetdata method once every n seconds

Timer = Timer.scheduledtimer (Timeinterval:5,

Target:self,selector: #selector (Orderdetailsviewctl.getnetdata),

Userinfo:nil,repeats:true)

Override Func Viewwilldisappear (_ Animated:bool) {

Super.viewwilldisappear (animated)

Emptying the timer when exiting

Timer.invalidate ()

}
