Question

timeintervalsince1970 是秒还是毫秒 ios

Answer 1

已经解决了。NSTimeInterval本身是个秒级别的double类型数值，小数点后面即毫秒数,*1000.0f即可得到毫秒级别的时间差//为了兼容java版本，事件是从1970/1/1开始-(NSDate *)getDateTimeFromMilliSeconds:(long long) miliSeconds{ NSTimeInterval tempMilli = miliSeconds; NSTimeInterval seconds = tempMilli/1000.0; NSLog(@"seconds=%f",seconds); return [NSDate dateWithTimeIntervalSince1970:seconds];}//将NSDate类型的时间转换为NSInteger类型,从1970/1/1开始-(long long)getDateTimeTOMilliSeconds:(NSDate *)datetime{ NSTimeInterval interval = [datetime timeIntervalSince1970]; NSLog(@"interval=%f",interval); long long totalMilliseconds = interval*1000 ; NSLog(@"totalMilliseconds=%llu",totalMilliseconds); return totalMilliseconds; }
