前言

本文实现的效果类似于QQ空间里的好友发表的动态，会显示好友发表的时间，这里是处理显示几小时前，几分钟前，刚刚，昨天，前天这样的格式，下面来一起看看吧。

一：刚刚，几分钟前，几小时前

//时间NSString *createdTimeStr = @"2017-01-01 21:05:10";//把字符串转为NSdateNSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];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);

二：刚刚，几分钟前，几小时前，昨天，前天

//时间NSString *createdTimeStr = @"2017-01-01 21:05:10";//把字符串转为NSdateNSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];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 if ((temp = timeInterval/3600) > 24 && (temp = timeInterval/3600) < 48){ result = [NSString stringWithFormat:@"昨天"];}else if ((temp = timeInterval/3600) > 48 && (temp = timeInterval/3600) < 72){ result = [NSString stringWithFormat:@"前天"];}else{ result = createdTimeStr;} NSLog(@"%@",result);
