设置iphone日历活动的具体时间

Question

您好我正在尝试将日历事件添加到iphone的日历中，但我不确定如何设置特定的日期和时间。我在这里查看了答案Programmatically add custom event in the iPhone Calendar

所以我现在有：

Store.startDate = [NSDate Date] //this part is what I would like to set a specific year/month/day/hour/minutes at.

非常感谢任何帮助，谢谢。

Answer 1

看看here。

还有几个示例以及如何使用NSDateComponents。

NSDateComponents *comps = [[NSDateComponents alloc] init];

// date
[comps setDay:10];
[comps setMonth:8];
[comps setYear:2015];

// time
[comps setHour:17];
[comps setMinute:13];
[comps setSecond:21];

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *date = [gregorian dateFromComponents:comps];

Answer 2

获取当前日期

 NSLocale *en_US_POSIX = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"];
    assert(en_US_POSIX != nil);
    NSDate *currentTime = [NSDate date];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setLocale:en_US_POSIX];
    [dateFormatter setDateFormat:@"dd-MM-yyyy"];
    NSString *resultString = [dateFormatter stringFromDate: currentTime];

获取当前时间

NSDate* now = [NSDate date];
    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
    NSDateComponents *dateComponents = [gregorian components:(NSCalendarUnitHour  | NSCalendarUnitMinute | NSCalendarUnitSecond) fromDate:now];
    NSInteger hour = [dateComponents hour];
    NSString *am_OR_pm=@"AM";
    if (hour>12){
        hour=hour%12;
        am_OR_pm = @"PM";
    }
    NSInteger minute = [dateComponents minute];
    NSString *strTime=[NSString stringWithFormat:@"%02d:%02d %@", hour, minute ,am_OR_pm];
