NSTimer Too Slow

由 南笙酒味 提交于 2019-11-28 12:59:13
问题 I have seen multiple questions similar to this; however, none of them resolved my problem. My timer is simply going too slowly. I am only using an interval of 0.01 seconds. Here is my code: @IBOutlet var timerLabel: UILabel! var miliseconds = 0 var seconds = 0 func updateLabel() { if miliseconds == 0 { timerLabel.text = "\(seconds).00" } else if miliseconds < 10 { timerLabel.text = "\(seconds).0\(miliseconds)" } else { timerLabel.text = "\(seconds).\(miliseconds)" } } var timer = NSTimer()

I am developing an iPhone game and I have an NSTimer that animates all of the objects on the screen: EverythingTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/30.0 target:self selector:@selector(moveEverything) userInfo:nil repeats:YES]; Most of the time it runs very smoothly, but sometimes I see things move slower or choppy.

Objective-C : NSTimer and countdown

由 99封情书 提交于 2019-11-28 09:29:53
I know that I should understand Apple's documentation for NSTimer, but I don't! I have also read a lot of questions about it but can not find one that suites my case. Well here it is: The user enter hour and minutes through textfields. I convert those to integers and display them in a "countDownLabel". How can i make the count down to zero? It would be nice to show the seconds which is something that the user didn't imported but i guess it will not be hard to show. How could somebody stop this procedure with a press of a UIButton? I know that i am asking a lot...I would be really grateful if

Best time to invalidate NSTimer inside UIViewController to avoid retain cycle

由 為{幸葍}努か 提交于 2019-11-28 05:46:05
Does any one know when is the best time to stop an NSTimer that is held reference inside of a UIViewController to avoid retain cycle between the timer and the controller? Here is the question in more details: I have an NSTimer inside of a UIViewController. During ViewDidLoad of the view controller, I start the timer: statusTimer = [NSTimer scheduledTimerWithTimeInterval: 1 target: self selector: @selector(updateStatus) userInfo: nil repeats: YES]; The above causes the timer to hold a reference to the view controller. Now I want to release my controller (parent controller releases it for

applicationDidEnterBackground and applicationWillEnterForeground method are not called when pressed home button in iOS simulator

问题 I need a long running task to be done in background as well as in foreground. This updates the core data. So to maintain UI responsive I created an another thread where I use different managedObjectContext(MOC).

Before the task is starting and after the task is completed when I press home button it calls the two delegate methods properly but during the task is active when I press home
