我有一个应用程序,我正试图帮助走出门。这段代码最初是由另一个团队使用 iOS5 编写的。我添加了成功运行的 requestAccessToEntityType:completion: 调用。但是,在被授予访问权限后,我没有得到任何来源/defaultCalendar 或基于实体的日历。而且我无法创建新日历。
调用 defaultCalendarForNewEvents 时出现此错误
Error Domain=EKCADErrorDomain Code=1013 "The operation couldn’t be completed. (EKCADErrorDomain error 1013.)"
结果为零。
如果我退出 viewController 尝试执行此操作并返回,一切正常。如果在收到关于没有来源的警报后,我继续尝试(没有退出 viewController),它会反复失败。
我想强调,授权调用有效(用户被要求访问日历并提供它,然后调用以确认授权通过)。我发现的所有其他类似的问题都作为解决方案 - 确保您 requestAccessToEntityType
[eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
if (granted)
{
//[self performSelectorOnMainThread:@selector(doScheduleActivity:) withObject:activity waitUntilDone:YES];
dispatch_async(dispatch_get_main_queue(), ^{
[self doScheduleActivity:activity];
});
}
else
{ // probably should force the main thread
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Calendar Access Required" message:@"In order to schedule activities, APP needs access to your Calendar. You can change this in your device Settings." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[av show];
});
}
}] ;
granted
返回 true 并且 [self doScheduleActivity: 被调用。下面的代码是在该例程的最开始调用的一个函数,也是失败的地方。
EKCalendar *saCalendar;
EKSource *source;
NSError *error;
UIAlertView *alert;
LogDebug(@"eventStore defaultCalendar %@", [eventStore defaultCalendarForNewEvents]);
// validate access to calendar prior to segueing
if ([EKEventStore respondsToSelector:@selector(authorizationStatusForEntityType:)])
{
switch([EKEventStore authorizationStatusForEntityType:EKEntityTypeEvent])
{
case EKAuthorizationStatusAuthorized:
break;
case EKAuthorizationStatusNotDetermined:
{
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:SA_ALERT_CAPTION_CALENDAR_ACCESS_NOT_DETERMINED message:SA_ALERT_BODY_CALENDAR_ACCESS_NOT_DETERMINED delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
});
return false;
}
case EKAuthorizationStatusDenied:
{
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:SA_ALERT_CAPTION_CALENDAR_ACCESS_DENIED message:SA_ALERT_BODY_CALENDAR_ACCESS_DENIED delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
});
return false;
}
case EKAuthorizationStatusRestricted:
{
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:SA_ALERT_CAPTION_CALENDAR_ACCESS_RESTRICTED message:SA_ALERT_BODY_CALENDAR_ACCESS_RESTRICTED delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
});
return false;
}
default:
break;
}
}
// search for application specifc calendar..
saCalendar = nil;
for(EKCalendar *calendar in [eventStore calendarsForEntityType:EKEntityTypeEvent])
{
if([calendar.title isEqualToString:SA_ACTIVITIES_CALENDAR_TITLE])
{
saCalendar = calendar;
break;
}
}
// ..and create from scratch if nonexistent
if(nil == saCalendar)
{
// find local source to hook up new calendar to
for(source in [eventStore sources])
{
if(source.sourceType == EKSourceTypeLocal)
{
break;
}
}
// if could not find local source type, something is wrong
if( source == nil || source.sourceType != EKSourceTypeLocal)
{
alert = [[UIAlertView alloc] initWithTitle:SA_ALERT_CAPTION_CALENDAR_ERROR_NO_SOURCE message:SA_ALERT_BODY_CALENDAR_ERROR delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
return false;
}
// create calendar for applcation, name it, color it and assign source
saCalendar = [EKCalendar calendarForEntityType:EKEntityTypeEvent eventStore:eventStore];
[saCalendar setSource:source];
[saCalendar setTitle:SA_ACTIVITIES_CALENDAR_TITLE];
[saCalendar setCGColor:[[UIColor yellowColor] CGColor]];
// create immediately
error = nil;
if(![eventStore saveCalendar:saCalendar commit:true error:&error])
{
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:SA_ALERT_CAPTION_CALENDAR_ERROR_CANT_SAVE message:SA_ALERT_BODY_CALENDAR_ERROR delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
});
return false;
}
}
return true;
尽管已获得授权,但一切都返回 nil 并且签入[EKEventStore authorizationStatusForEntity:EKEntityType
返回 EKAuthorizationStatusAuthorized
在我在这里遇到故障后,如果我退出这个视图控制器并重新进入,它就可以工作。这只发生在系统第一次要求用户访问日历并且他们回复 OK 时。
感谢您的任何见解。我一直在逐步调试调试器,并进行 printf 类型调试以避免任何时间问题等,并且没有看到与我在 Apple 网站上查找的事件内容相反的内容。
