• 前段時(shí)間一直在和時(shí)間打交道,這幾天整理了一下幾個(gè)時(shí)間相互轉(zhuǎn)換的方法,再次做記錄
• 效果圖

• 時(shí)間戳轉(zhuǎn)字符串

+(NSString *)timeStampConversionNSString:(NSString *)timeStamp
{
    NSDate *date = [NSDate dateWithTimeIntervalSince1970:[timeStamp longLongValue]/1000];
    NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    NSString *dateStr = [formatter stringFromDate:date];
    return dateStr;
}

• 時(shí)間轉(zhuǎn)時(shí)間戳

+(NSString *)dateConversionTimeStamp:(NSDate *)date
{
    NSString *timeSp = [NSString stringWithFormat:@"%ld", (long)[date timeIntervalSince1970]*1000];
    return timeSp;
}

• 字符串轉(zhuǎn)時(shí)間

+(NSDate *)nsstringConversionNSDate:(NSString *)dateStr
{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
    NSDate *datestr = [dateFormatter dateFromString:dateStr];
    return datestr;
}
