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);
