我会将公历日期转换为回历(伊斯兰)日期。可以在网上搜索后,我找到了一个源代码来转换它。我将代码从Java和PHP转换为C base。
这个工具有时工作起来没有任何问题。但有时也会有问题。
我需要你的帮助,要么修复工具或一个可用代码,将没有任何问题的工作!顺便说一句,我找到了另一个源代码(基于C++的http://emr.cs.iit.edu/~reingold/calendar.C)。因为我不知道C++是否有人可以将它转换成C基础或Objective C将是完美的(仍然不确定这段代码是否能正常工作)。

假设这是针对Mac (Cocoa)或iOS (Cocoa Touch)应用程序的,因为这是你最常看到的Objective C,那么你可以这样做:
// Create a Gregorian Calendar
NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
// Set up components of a Gregorian date
NSDateComponents *gregorianComponents = [[NSDateComponents alloc] init];
gregorianComponents.day = 4;
gregorianComponents.month = 12;
gregorianComponents.year = 2010;
// Create the date
NSDate *date = [gregorianCalendar dateFromComponents:gregorianComponents];
[gregorianComponents release];
[gregorianCalendar release];
// Then create an Islamic calendar
NSCalendar *hijriCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSIslamicCivilCalendar];
// And grab those date components for the same date
NSDateComponents *hijriComponents = [hijriCalendar components:(NSDayCalendarUnit |
NSMonthCalendarUnit |
NSYearCalendarUnit)
fromDate:date];
NSLog(@"[In Hijri calendar ->] Day: %ld, Month: %ld, Year:%ld",
[hijriComponents day],
[hijriComponents month],
[hijriComponents year]);
[hijriCalendar release];如果您想要的只是当前日期,那么您可以完全跳过设置公历日期,只需执行以下操作:
// Create an Islamic calendar
NSCalendar *hijriCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSIslamicCalendar];
// And grab the date components for the current date
NSDateComponents *hijriComponents = [hijriCalendar components:(NSDayCalendarUnit |
NSMonthCalendarUnit |
NSYearCalendarUnit)
fromDate:[NSDate date]];

看看这个主题:how to convert hijari date into gregorian date in java script?
这个问题提到了JavaScript,但最上面的答案似乎有各种语言的实现链接。

你应该能够使用NSCalendar在Objective-C中做到这一点(如果这确实是一种选择)。
