IOS的日期差异 [英] Date Difference in IOS

问题描述

我从日期到现在都有两个日期。我在NSString中分别存储了两个日期，如string1和string 2。现在我的问题是我想要这两个日期的区别。我的日期格式是 2014年3月4日和 2014年3月14日，我希望结果像code> 10 。

解决方案

我认为，根据你的问题， 两个日期之间的差异。你可以用这个

  NSDateFormatter * dateFormat = [[NSDateFormatter alloc] init]; 
 [dateFormat setDateFormat：@dd-MM-yyyy]; 
 NSDate * date1 = [dateFormat dateFromString：@04-Mar-2014]; 
 NSDate * date2 = [dateFormat dateFromString：@2014年3月14日]; 
 
 NSTimeInterval secondsBetween = [date2 timeIntervalSinceDate：date1]; 
 
 int numberOfDays = secondsBetween / 86400; 
 
 NSLog（@两个日期之间有％d天，numberOfDays）; 
  

I had Two Dates from date and to date. I stored two dates in NSString like string1 and string 2 respectively. Now My Problem is I want the difference of these two dates. My Date format is 04-Mar-2014 and 14-Mar-2014 and I want the result to be like 10.

解决方案

I think, according to your question, my assumption is difference between two dates. You can use this.

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd-MM-yyyy"];
NSDate *date1 = [dateFormat dateFromString:@"04-Mar-2014"];
NSDate *date2 = [dateFormat dateFromString:@"14-Mar-2014"];

NSTimeInterval secondsBetween = [date2 timeIntervalSinceDate:date1];

int numberOfDays = secondsBetween / 86400;

NSLog(@"There are %d days in between the two dates.", numberOfDays);
