如何在Iphonesdk中创建NSTimer

Question

我是Iphone编程新手我想了解如何在Xcode Iphonesdk中创建NSTimer。谁能建议我？

Answer 1

NSTimer *timer = [NSTimer scheduleTimerWithTimeInterval:TIME_INTERVAL target:self selector:@selector(YOUR_METHOD_NAME) userInfo:nil repeats:YES/NO];

希望这会对你有帮助........

Answer 2

以下是添加NSTimer的代码..

1) in .h file
NSTimer *timer;

2) in .m file
timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(YOUR_METHOD_NAME) userInfo:nil repeats:YES];

注意::所以你的方法会在每1秒钟后连续调用..如果你想调用计时器方法只设置一次重复：NO ...

使计时器无效

3) to invalidate the timer where you want..
   [timer invalidate];
