前言
本文實現的效果類似於QQ空間裡的好友發表的動態,會顯示好友發表的時間,這裡是處理顯示幾小時前,幾分鐘前,剛剛,昨天,前天這樣的格式,下面來一起看看吧。
一:剛剛,幾分鐘前,幾小時前
//時間 NSString *createdTimeStr = @"2017-01-01 21:05:10"; //把字符串轉為NSdate NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; NSDate *timeDate = [dateFormatter dateFromString:createdTimeStr]; //得到與當前時間差 NSTimeInterval timeInterval = [timeDate timeIntervalSinceNow]; timeInterval = -timeInterval; long temp = 0; NSString *result; if (timeInterval < 60) { result = [NSString stringWithFormat:@"剛剛"]; }else if((temp = timeInterval/60) < 60){ result = [NSString stringWithFormat:@"%ld分鐘前",temp]; }else if((temp = timeInterval/3600) > 1 && (temp = timeInterval/3600) <24){ result = [NSString stringWithFormat:@"%ld小時前",temp]; }else{ result = createdTimeStr; } NSLog(@"%@",result);
二:剛剛,幾分鐘前,幾小時前,昨天,前天
//時間 NSString *createdTimeStr = @"2017-01-01 21:05:10"; //把字符串轉為NSdate NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; NSDate *timeDate = [dateFormatter dateFromString:createdTimeStr]; //得到與當前時間差 NSTimeInterval timeInterval = [timeDate timeIntervalSinceNow]; timeInterval = -timeInterval; long temp = 0; NSString *result; if (timeInterval < 60) { result = [NSString stringWithFormat:@"剛剛"]; }else if((temp = timeInterval/60) < 60){ result = [NSString stringWithFormat:@"%ld分鐘前",temp]; }else if((temp = timeInterval/3600) > 1 && (temp = timeInterval/3600) <24){ result = [NSString stringWithFormat:@"%ld小時前",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);
