计算可可的时间差 [英] Calculate time difference in Cocoa

问题描述

我有两个时间值格式：％H％M％S（EG161500）

这些值是基于文本的整数。

在Cocoa中有一个简单的函数，使用60秒和分钟刻度来计算这两个整数之间的差值。

 时间1 = 161500 
时间2 = 171500 
 
 timedifference = 003000 
  
 
 
解决方案
 
  NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init] autorelease]; 
 [dateFormatter setDateFormat：@HHmmss]; 
 
 NSDate * date1 = [dateFormatter dateFromString：@161500]; 
 NSDate * date2 = [dateFormatter dateFromString：@171500]; 
 
 NSTimeInterval diff = [date2 timeIntervalSinceDate：date1]; // diff = 3600.0 
  
 
I have got two timevalues in the format: %H%M%S  (E.G.161500)

These values are text-based integers.

Is there a simple function in Cocoa that calculates the difference between these two integers using a 60 seconds and minutes scale?

So if
time 1 = 161500
time 2 = 171500

timedifference = 003000

解决方案
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:@"HHmmss"];

NSDate *date1 = [dateFormatter dateFromString:@"161500"];
NSDate *date2 = [dateFormatter dateFromString:@"171500"];

NSTimeInterval diff = [date2 timeIntervalSinceDate:date1]; // diff = 3600.0
