Should I use NSTimer?

Question

Mobile development

Good afternoon! I am writing a mobile application, and there you need to consider whether there is a network connection. If there is no connection, then the buttons disappear. So I solved this problem with the help of NSTimer and the Reachability class. Some code looks like this:
self.timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("checkConnection"), userInfo: nil, repeats: true)
...
func checkConnection() {
if Reachability.isConnectedToNetwork() != true{
//Disable buttons here...
}
}
Am I doing the right thing? Will the timer load the system? How do you check your internet connection?

Answer 1

Reachability can send notifications when the network disappears or appears, google
search gives great examples:
