在我的基于日历的应用程序中，我面临着来自应用程序商店构建的大量崩溃。但是，我无法重现，也没有遇到开发过程中的崩溃。
来自 Fabric 的崩溃日志:

我想解决这个崩溃问题，我上周在所有论坛上都尝试过。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()
}];
}];
}
我的实用工具:
@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
提前致谢
最佳答案
您没有发布足够的信息；你在 -[EKObject relationForKey:] 方法内的某个地方发生了崩溃；更重要的是，您还没有发布崩溃的确切原因；
在我看来，这个方法 [EKObject relationForKey:] 在某个地方从自身生成 dict，并且可能是 [__NSDictionaryM setObject:forKey:] 在这里你尝试将 nil 插入 dict
