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NSdate
NSDateFormatter *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NSdate
NSDateFormatter *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);
