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.
答
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];
