秒到 - 分钟 - 小时 - 毫秒

问题描述:

我正在使用 NSTimer,代码如下:

I'm using the NSTimer, with this code:

- (IBAction)start:(id)sender {

    MainInt = 0;

    timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countup) userInfo:nil repeats:YES];

}

如何同时显示毫秒和分钟?

How can I display milliseconds and minutes also?

没有找到任何简单而有效的方法.

Didn't find any simple yet working method.

对于毫秒使用:

timer = [NSTimer scheduledTimerWithTimeInterval:0.001 target:self selector:@selector(countup)userInfo:nil repeats:YES];

分钟使用:

timer = [NSTimer scheduledTimerWithTimeInterval:60.0 target:self selector:@selector(countup)userInfo:nil repeats:YES];
