一仲墨、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)間室谚,日期
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];// 創(chuàng)建一個(gè)時(shí)間格式化對(duì)象
[dateFormatter setDateFormat:@"YYYY/MM/dd hh:mm:ss SS "];//設(shè)定時(shí)間格式,這里可以設(shè)置成自己需要的格式
NSString *dateString = [dateFormatter stringFromDate:currentDate];//將時(shí)間轉(zhuǎn)化成字符串
return dateString;
}
二傻昙、獲取當(dāng)前時(shí)間戳
//獲取當(dāng)前時(shí)間戳
- (NSString *)currentTimeStr{
NSDate* date = [NSDate dateWithTimeIntervalSinceNow:0];//獲取當(dāng)前時(shí)間0秒后的時(shí)間
NSTimeInterval time=[date timeIntervalSince1970]*1000;// *1000 是精確到毫秒锄开,不乘就是精確到秒
NSString *timeString = [NSString stringWithFormat:@"%.0f", time];
return timeString;
}
三古沥、時(shí)間戳轉(zhuǎn)時(shí)間
// 時(shí)間戳轉(zhuǎn)時(shí)間,時(shí)間戳為13位是精確到毫秒的瘸右,10位精確到秒
- (NSString *)getDateStringWithTimeStr:(NSString *)str{
NSTimeInterval time=[str doubleValue]/1000;//傳入的時(shí)間戳str如果是精確到毫秒的記得要/1000
NSDate *detailDate=[NSDate dateWithTimeIntervalSince1970:time];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; //實(shí)例化一個(gè)NSDateFormatter對(duì)象
//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"];
NSString *currentDateStr = [dateFormatter stringFromDate: detailDate];
return currentDateStr;
}
四、字符串轉(zhuǎn)時(shí)間戳
//字符串轉(zhuǎn)時(shí)間戳 如:2017-4-10 17:15:10
- (NSString *)getTimeStrWithString:(NSString *)str{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];// 創(chuàng)建一個(gè)時(shí)間格式化對(duì)象
[dateFormatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"]; //設(shè)定時(shí)間的格式
NSDate *tempDate = [dateFormatter dateFromString:str];//將字符串轉(zhuǎn)換為時(shí)間對(duì)象
NSString *timeStr = [NSString stringWithFormat:@"%ld", (long)[tempDate timeIntervalSince1970]*1000];//字符串轉(zhuǎn)成時(shí)間戳,精確到毫秒*1000
return timeStr;
}
