一、 獲取當(dāng)前時(shí)間

// 獲取當(dāng)前時(shí)間
- (NSString *)currentDateStr{
    NSDate *currentDate = [NSDate date];//獲取當(dāng)前時(shí)間，日期
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    //設(shè)定時(shí)間格式,這里可以設(shè)置成自己需要的格式
    // [dateFormatter setDateFormat:@"YYYY/MM/dd hh:mm:ss SS"];
    [dateFormatter setDateFormat:@"YYYY/MM/dd hh:mm:ss SS"];
    NSString *dateString = [dateFormatter stringFromDate:currentDate];
    return dateString;
}

二、時(shí)間戳轉(zhuǎn)時(shí)間

// 時(shí)間戳轉(zhuǎn)時(shí)間
- (NSString *)getDateStringWithDate:(NSString *)dataStr{
    // dataStr時(shí)間戳
    NSTimeInterval time=[dataStr doubleValue]+28800;//因?yàn)闀r(shí)差問題要加8小時(shí) == 28800 sec
    NSDate *detaildate=[NSDate dateWithTimeIntervalSince1970:time];
//    NSLog(@"date:%@",[detaildate description]); 
    //實(shí)例化一個(gè)NSDateFormatter對象
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    //設(shè)定時(shí)間格式,這里可以設(shè)置成自己需要的格式
//    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    [dateFormatter setDateFormat:@"MM月dd日 HH:mm"];
    NSString *currentDateStr = [dateFormatter stringFromDate: detaildate];
    return currentDateStr;
}
