我正在使用ios 6 中的eventkit框架开发日历应用程序。我正在尝试使用该[self.store respondsToSelector:@selector(requestAccessToEntityType:completion:)]方法获得权限，并且在获得访问日历的权限后，我正在尝试使用EKSourceTypeLocal源创建带有标识符的新日历并将事件添加到新创建的日历。我在这里遇到的问题是，当我尝试在 iPhone 4s 中运行该应用程序时，它显示“日历没有来源”的错误，并且它没有保存我的日历，因此没有事件被添加到日历中。我不知道我在这里做错了什么。请指导我解决这个问题。
我在下面发布我的代码
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSLog(@"in view did load method");
// For iOS 6.0 and later
self.store = [[EKEventStore alloc] init];
if([self.store respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
[self.store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
// handle access here
dispatch_async(dispatch_get_main_queue(), ^{
if (granted) {
NSLog(@"permission granted");
EKCalendar *myCalendar;
EKSource *myLocalSource = nil;
for (EKSource *calendarSource in self.store.sources) {
if (calendarSource.sourceType == EKSourceTypeLocal) {
myLocalSource = calendarSource;
break;
}
}
if (!myLocalSource)
return;
NSString *mycalIndentifier = [[NSUserDefaults standardUserDefaults] valueForKey:@"my_calendar_identifier"];
if (mycalIndentifier == NULL) {
// Create a new calendar of type Local... save and commit
myCalendar = [EKCalendar calendarForEntityType:EKEntityTypeEvent eventStore:self.store];
myCalendar.title = @"New_Calendar";
myCalendar.source = myLocalSource;
NSString *calendarIdentifier = myCalendar.calendarIdentifier;
NSError *error = nil;
[_store saveCalendar:myCalendar commit:YES error:&error];
if (!error) {
NSLog(@"created, saved, and commited my calendar with id %@", myCalendar.calendarIdentifier);
[[NSUserDefaults standardUserDefaults] setObject:calendarIdentifier forKey:@"my_calendar_identifier"];
} else {
NSLog(@"an error occured when creating the calendar = %@", error.description);
error = nil;
}
//create an event
// Create a new event... save and commit
EKEvent *myEvent = [EKEvent eventWithEventStore:_store];
myEvent.allDay = NO;
myEvent.startDate = [NSDate date];
myEvent.endDate = [NSDate date];
myEvent.title = @"Birthday";
myEvent.calendar = myCalendar;
[_store saveEvent:myEvent span:EKSpanThisEvent commit:YES error:&error];
if (!error) {
NSLog(@"the event saved and committed correctly with identifier %@", myEvent.eventIdentifier);
} else {
NSLog(@"there was an error saving and committing the event");
error = nil;
}
EKEvent *savedEvent = [_store eventWithIdentifier:myEvent.eventIdentifier];
NSLog(@"saved event description: %@",savedEvent);
}
else{
myCalendar = [_store calendarWithIdentifier:mycalIndentifier];
}
}
else if(!granted){
NSLog(@"Permission not granted");
}
else{
NSLog(@"error = %@", error.localizedDescription);
}
});
}];
}
}
this is the error I am getting :
Predicate call to calendar daemon failed: Error Domain=EKCADErrorDomain Code=1013 "The operation couldn’t be completed. (EKCADErrorDomain error 1013.)"
not saved = Error Domain=EKErrorDomain Code=14 "Calendar has no source" UserInfo=0x1d5f6950 {NSLocalizedDescription=Calendar has no source}
