//时间
NSString *createdTimeStr = @ "2017-01-01 21:05:10" ;
//把字符串转为NSdate
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

NSDate *timeDate = [dateFormatter dateFromString:createdTimeStr];
//得到与当前时间差
NSTimeInterval timeInterval = [timeDate timeIntervalSinceNow];
timeInterval = -timeInterval;
long temp = 0 ;
NSString *result;
if (timeInterval < 60 ) {
result = [NSString stringWithFormat:@ "刚刚" ];
} else if ((temp = timeInterval/ 60 ) < 60 ){
result = [NSString stringWithFormat:@ "%ld分钟前" ,temp];
} else if ((temp = timeInterval/ 3600 ) > 1 && (temp = timeInterval/ 3600 ) < 24 ){
result = [NSString stringWithFormat:@ "%ld小时前" ,temp];
} else {
result = createdTimeStr;
}
NSLog(@ "%@" ,result);
