时间差在控制台输出中是一个不可读的大数字

iOS 上的新东西，这个 NSDate 快要死了。我只是想抓住时间差..所以我做了什么

NSDate *start=[NSDate date];
NSLog(@"Start date %d", start);

//---- some for loop jobs here ----

NSDate *end=[NSDate date];
NSLog(@"End date %d", end);
double timedifference= [end timeIntervalSinceDate:start];
NSLog(@"response time %d", timedifference);

以及我在控制台中得到的结果..

2011-08-27 12:27:51.505 TabNav[8153:e903] Start date 172118224
2011-08-27 12:27:53.304 TabNav[8153:e903] End date 92503392
2011-08-27 12:27:53.304 TabNav[8153:e903] response time 1073741824

如何将响应时间 1073741824 转换为秒？

谢谢

Kind of new on iOS and this NSDate is killing me..
I just want to grab the time difference.. so what I did

NSDate *start=[NSDate date];
NSLog(@"Start date %d", start);

//---- some for loop jobs here ----

NSDate *end=[NSDate date];
NSLog(@"End date %d", end);
double timedifference= [end timeIntervalSinceDate:start];
NSLog(@"response time %d", timedifference);

And the result I got in the console..

2011-08-27 12:27:51.505 TabNav[8153:e903] Start date 172118224
2011-08-27 12:27:53.304 TabNav[8153:e903] End date 92503392
2011-08-27 12:27:53.304 TabNav[8153:e903] response time 1073741824

How can I convert response time 1073741824 to second ?

Thanks

我认为这只是格式问题：

NSDate *start=[NSDate date];
NSLog(@"Start date %@", start);
                    ^

//---- some for loop jobs here ----

NSDate *end=[NSDate date];
NSLog(@"End date %@", end);
                  ^
double timedifference= [end timeIntervalSinceDate:start];
NSLog(@"response time %f", timedifference);
                       ^

I think it is just a matter of formatting:

NSDate *start=[NSDate date];
NSLog(@"Start date %@", start);
                    ^

//---- some for loop jobs here ----

NSDate *end=[NSDate date];
NSLog(@"End date %@", end);
                  ^
double timedifference= [end timeIntervalSinceDate:start];
NSLog(@"response time %f", timedifference);
                       ^
