小胖说事-------iOS利用代码添加事件到系统日历中

#import <EventKit/EventKit.h>

//事件市场
EKEventStore *eventStore = [[EKEventStore alloc] init];

//6.0及以上通过下面方式写入事件
if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])
{
// the selector is available, so we must be on iOS 6 or newer
[eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
if (error)
{
//错误细心
// display error message here
}
else if (!granted)
{
//被用户拒绝，不允许访问日历
// display access denied error message here
}
else
{
// access granted
// ***** do the important stuff here *****

//事件保存到日历

//创建事件
EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
event.title     = @"哈哈哈，我是日历事件啊";
event.location = @"我在杭州西湖区留和路";

NSDateFormatter *tempFormatter = [[NSDateFormatter alloc]init];
[tempFormatter setDateFormat:@"dd.MM.yyyy HH:mm"];

event.startDate = [[NSDate alloc]init ];
event.endDate   = [[NSDate alloc]init ];
event.allDay = YES;

//添加提醒
[event addAlarm:[EKAlarm alarmWithRelativeOffset:60.0f * -60.0f * 24]];
[event addAlarm:[EKAlarm alarmWithRelativeOffset:60.0f * -15.0f]];

[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];

UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:@"Event Created"
message:@"Yay!?"
delegate:nil
cancelButtonTitle:@"Okay"
otherButtonTitles:nil];
[alert show];

NSLog(@"保存成功");

}
});
}];
