程式碼實現:

//時間戳轉標準時間
- (void)Click1:(UIButton *)btn
{
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];//設定你想要的格式,hh與HH的區別:分別表示12小時制,24小時制

    NSString *str = [NSString stringWithFormat:@"%@",
                     [formatter stringFromDate:[NSDate dateWithTimeIntervalSince1970:[_timeTextFiled1.text integerValue]]]];
    _standardLable1.text = str;
    [_timeTextFiled1 resignFirstResponder];
}

//標準時間轉時間戳
- (void)Click2:(UIButton *)btn
{
    NSString *timeStr = _timeTextFiled2.text;
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"YYYYMMddHHmmss"]; // 設定你想要的格式,hh與HH的區別:分別表示12小時制,24小時制
    NSDate* date1 = [formatter dateFromString:timeStr]; //將字串按formatter轉成nsdate
    NSString *timeSp = [NSString stringWithFormat:@"%ld", (long)[date1 timeIntervalSince1970]];
    _standardLable2.text = timeSp;
    [_timeTextFiled2 resignFirstResponder];
}
