更新：这是工作示例。
首先，我们创建一个类来保存工作日、小时、分钟和秒：
我的类.h
#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
@interface myClass : NSObject {
NSString *weekday;
NSInteger hour;
NSInteger minute;
NSInteger second;
}
@property (nonatomic, strong) NSString *weekday;
@property (nonatomic, assign) NSInteger hour;
@property (nonatomic, assign) NSInteger minute;
@property (nonatomic, assign) NSInteger second;
@end
我的班级.m
#import "myClass.h"
@implementation myClass
@synthesize weekday, hour, minute, second;
@end
接下来，我们需要创建一个 myClass 的实例来保存我们的日期信息。
将此添加到 ViewController.h：
@property (nonatomic, strong) NSMutableArray *myArray;
这段代码可以放在 ViewController.m 中你想要的任何地方：
myArray = [[NSMutableArray alloc] init];
//Setup an instance of myClass
myClass *c = [[myClass alloc] init];
[c setWeekday:@"Monday"];
[c setHour:13];
[c setMinute:0];
[c setSecond:0];
[myArray addObject:c];
接下来我们需要弄清楚我们的事件在未来多远。感谢 rdelmar，我们有执行此操作的代码，他的答案如下
//Create a func that returns an NSDate. It requires that the Weekday, HR, Min and Secs are passed into it.
-(NSDate *)getNextDateOn:(NSString *)weekday atHour:(NSInteger)hour minute:(NSInteger)mins second:(NSInteger)secs {
//Setup an array of weekdays to compare to the imported (NSString *)weekday
NSArray *array = [NSArray arrayWithObjects:@"Sunday",@"Monday",@"Tuesday",@"Wednesday",@"Thursday",@"Friday",@"Saturday",nil];
NSInteger weekdayNumber = [array indexOfObject:[weekday capitalizedString]] + 1;
//This code finds how many days in the future the imported (NSString *)weekday is
NSDate *now = [NSDate date];
NSCalendar *cal = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *nowComps = [cal components:NSWeekdayCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit fromDate:now];
NSInteger daysForward = (weekdayNumber - nowComps.weekday + 7) % 7;
//Lastly, create an NSDate called eventDate that consists of the
NSDateComponents *eventComps = [[NSDateComponents alloc] init];
[eventComps setDay:daysForward];
[eventComps setHour: hour - nowComps.hour];
[eventComps setMinute: mins - nowComps.minute];
[eventComps setSecond: secs - nowComps.second];
eventDate = [cal dateByAddingComponents:eventComps toDate:now options:0];
return eventDate;
}
在这里，我们获取新创建的 eventDate 并使用它在 iCal 中创建我们的事件：
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = @"Move your car!";
event.startDate = eventDate;
event.endDate = [[NSDate alloc] initWithTimeInterval:60.0f * 60.0f sinceDate:event.startDate]; //1 hr long
[event addAlarm:[EKAlarm alarmWithRelativeOffset:60.0f * -30.0f]]; //30 min before
//eventLoc was created using CLGeocoder and the method reverseGeocodeLocation:
//The location is not necessary to create an event but if you'd like the code, ask and i'll post it.
[event setLocation:eventLoc];
[event setNotes:@"This event was set by me. ;P"];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
NSLog(@"Event Set");
我希望这对某人有帮助，就像它对我有帮助一样。
：更新结束：
我已经阅读了 NSDate 的文档，希望找到一种简单的方法来找到“下一个即将到来的周一下午 1:00”。
例如，假设面包店每周 1 天（星期四）从上午 9 点到下午 6 点营业……如果现在是星期四上午 8 点，我想从现在开始获得 1 小时的 NSDate。如果今天是星期四 @ 晚上 7 点，我希望下个星期四上午 9 点的 NSDate。
我计划在 iCal 中进行活动（测试已成功），但问题在于计算活动时间。
你能指出我对 NSDate 的一个很好的解释或帮助我弄清楚如何计算我正在寻找的 NSDate 吗？
我正在寻找修复此代码：
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = @"Bakery's Open!";
event.startDate = [[NSDate alloc] init];
event.endDate = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
