毫秒转换成秒 ios?ios 隔多久后的时间?NSTimeInterval的使用

你是否正在寻找关于nstimeinterval的内容？让我把最权威的东西奉献给你：

第一种方式：
nstimeinterval time = ...;
NSString *string = [NSString stringWithFormat:@"%02li:%02li:%02li",
lround(floor(time / 3600.)) % 100,
lround(floor(time / 60.)) % 60,
lround(floor(time.)) % 60];

第二种方式：
// You could also have stored the start time using
// CFAbsoluteTimeGetCurrent()
nstimeinterval elapsedTime = [startDate timeIntervalSinceNow];

// Divide the interval by 3600 and keep the quotient and remainder
div_t h = div(elapsedTime, 3600);
int hours = h.quot;
// Divide the remainder by 60; the quotient is minutes, the remainder
// is seconds.
div_t m = div(h.rem, 60);
int minutes = m.quot;
int seconds = m.rem;

// If you want to get the individual digits of the units, use div again
// with a divisor of 10.

NSLog(@"%d:%d:%d", hours, minutes, seconds)

如果您有您初始日期存储在 NSDate 对象时，您可以获得新日期任何时间间隔在未来，。只需使用 dateByAddingTimeInterval: 像这样：

NSDate * originalDate = [NSDate date];
nstimeinterval interval = 1;
NSDate * futureDate = [originalDate dateByAddingTimeInterval:interval];

ios获取自1970年以来的毫秒数同java的System.currentTimeMillis()

+ (NSString*)generateTimeIntervalWithTimeZone { NSMutableString *result = [[NSMutableString alloc] init]; NSDate *date = [NSDate date]; NSTimeInterval time = [date timeIntervalSince1970]*1000;//毫秒数要乘以1000 double i=time; //nstimeinterval返回的是double类型 NSDateFormatter *format = [[NSDateFormatter alloc] init]; [format setDateFormat:@"Z"]; NSString *timeZone = [format stringFromDate:date]; NSString *timeIntervalStr = [NSString stringWithFormat:@"%.f", i]; [result appendString:timeIntervalStr]; [result appendString:timeZone]; return result; }

以上就是关于nstimeinterval的全部内容，相信你一定会非常满意。
