我有一個NS定時器倒計時,它完美地工作得很好,這要歸功於你的答案。但是,我的計時器跳過了最後一秒,因此它不會計算最後0秒:99毫秒。我的代碼有什麼問題嗎?最好的祝福!NSTimer倒計時跳過上一秒(不使用最後毫秒)
-(void) setTimer {
MySingletonCenter *tmp = [MySingletonCenter sharedSingleton];
tmp.milisecondsCount = 99;
tmp.secondsCount = 2;
tmp.countdownTimerGame = [NSTimer scheduledTimerWithTimeInterval:.01 target:self selector:@selector(timerRun) userInfo:nil repeats:YES];
}
-(void) timerRun {
MySingletonCenter *tmp = [MySingletonCenter sharedSingleton];
tmp.milisecondsCount = tmp.milisecondsCount - 1;
if(tmp.milisecondsCount == 0){
tmp.secondsCount -= 1;
if (tmp.secondsCount == 0){
//Stuff for when the timer reaches 0
[tmp.countdownTimerGame invalidate];
tmp.countdownTimerGame = nil;
tmp.lives = tmp.lives - 1;
NSString *newLivesOutput = [NSString stringWithFormat:@"%d", tmp.lives];
livesLabel.text = newLivesOutput;
if (tmp.lives == 0) {
timeLabel.text = @"0:00";
[self performSelector:@selector(stopped) withObject:nil afterDelay:2.0];
}
else {[self setTimer]; }
}
else
tmp.milisecondsCount = 99;
}
NSString *timerOutput = [NSString stringWithFormat:@"%2d:%2d", tmp.secondsCount, tmp.milisecondsCount];
timeLabel.text = timerOutput;
}
我已經試過了。但它不起作用。無論如何感謝您的回答。 –
