【问题描述】：
在我的基于日历的应用程序中，我遇到了来自应用程序商店构建的大量崩溃。但是，我无法重现，也没有遇到这种开发崩溃。
Fabric 的崩溃日志：
-[EKEventStore(Utils) calendarByRetrievingSafelyWithIdentifier:forEntityType:]

我想修复这个崩溃，上周我尝试了所有论坛。我找不到任何有用的线索来解决我的问题。 请指导我手动重现此类崩溃并帮助解决。
我的代码：
NSOperationQueue *calendarDataStoresQueue = [[NSOperationQueue alloc] init];
for (EKCalendar *calendar in calendars) {
[calendarDataStoresQueue addOperationWithBlock:^{
MyCalendarDataStore *calendarDataStore = [[MyCalendarDataStore alloc] initWithCalendar:[[MYCalendar alloc] initWithInfoOfEventKitCalendar:calendar] eventStore:weakSelf.eventStore];
[calendarDataStore syncCalendarItems:items startDate:syncFrom endDate:syncTo completion:^{
complition()
}];
}];
}
我的实用程序：
@implementation EKEventStore (Utils)
- (EKCalendar*)calendarByRetrievingSafelyWithIdentifier:(NSString *)identifier forEntityType:(EKEntityType)entityType {
EKCalendar *calendar;
NSArray *calendars = [self calendarsForEntityType:entityType];
for (EKCalendar *aCalendar in calendars) {
if([aCalendar.calendarIdentifier isEqualToString:identifier]) {
calendar = aCalendar;
break;
}
}
return calendar;
}
@end
提前谢谢

你试过
Exception Breakpoint吗？ -
是的，我已经检查过了，仍然没有运气。
