在我的基于日历的应用程序中,我遇到了来自应用商店构建的大量崩溃。但是,我无法重现,也没有面对这次开发的崩溃。如何调试和重现`NSOperationQueue`崩溃

崩溃日志从面料:

-[EKEventStore(Utils) calendarByRetrievingSafelyWithIdentifier:forEntityType:] 

    Crashed: NSOperationQueue 0x17403fd60 :: NSOperation 0x17425bfc0 (QOS: DEFAULT)

我想解决这个问题的碰撞,我过去的一周试图与所有论坛。我无法得到任何有用的线索来解决我的问题。 请指导我手动重现这种类型的崩溃,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utils的:

@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

你没有张贴足够的信息;你的内部崩溃了 - [EKObject relationForKey:]方法;甚至更多,你没有发布你的崩溃的确切原因;

在我看来,这个方法[EKObject relationForKey:]从自身生成字典的地方,并可能是,[__NSDictionaryM的setObject:forKey:]在这里,你尝试插入零到字典

请检查崩溃日志“3 EventKit 0x19ab9d718 - [EKEventStore calendarsForEntityType:] + 512”。我在我的问题中给出了这个代码,之后都是eventKit框架函数。 – Ammaiappan

是的,我已经做了'但它不包含必要的信息;你能发布这个崩溃的布料页面的截图吗? –
