前言
本文實現的效果類似于QQ空間里的好友發表的動態，會顯示好友發表的時間，這里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NSdateNSDateFormatter *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NSdateNSDateFormatter *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);總結
以上就是這篇文字的全部內容了，希望本文的內容對各位iOS開發者能帶來一定的幫助，如果有疑問大家可以留言交流。
