应用程序崩溃与NSRangeException _PFBatchFaultingArray使用NSFetchedResultsController

我收到很多关于一个指定崩溃的崩溃报告，但不知道从哪里开始修复它，因为我无法自己重现它，并且崩溃报告是匿名发送的。应用程序崩溃与NSRangeException _PFBatchFaultingArray使用NSFetchedResultsController

正如您所看到的，它与我正在使用的NSFetchedResultsController有关。

下面是该崩溃报告的摘录。报告之间的唯一区别是索引[...]index (someLargeIndex) beyond bounds (1)[...]的范围。其余的在每个报告中保持不变。

Application Specific Information: 
*** Terminating app due to uncaught exception \\\'NSRangeException\\\', reason: \\\'*** -[_PFBatchFaultingArray objectAtIndex:]: index (262144) beyond bounds (1)\\\'

[_PFBatchFaultingArray objectAtIndex：]：索引（262144）超越边界（1）它必须做你的数组，访问262144数组_PFBatchFaultingArray索引只有2个元素（边界1 ）。我会说看看你的崩溃报告的其他线程。 – ARC

你有没有想过呢？我无法在任何地方找到答案 –

尝试查看你的cellForRowAtIndexPath：或者你使用NSFetchedResultsController的结果。还有，使用下面的代码，看看有多少结果提供给你：

NSArray *sections = fetchController.sections; 
int someSection = 0; 
id <NSFetchedResultsSectionInfo> sectionInfo = [sections objectAtIndex:someSection]; 
numberOfObjects = [sectionInfo numberOfObjects];

，然后转至您尝试获得的信息，这个地方可能是，你拨打：

[fetchedResultsController objectAtIndexPath:indexPath];

和看你传过来什么：

NSLog(@"row to be retrieved: %d", indexPath.row); 
[fetchedResultsController objectAtIndexPath:indexPath]; //here comes the crash

最终，你可以检查

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

查看有多少行正在返回。

这可能是NSFetchedResultsController的缓存问题。看到这个问题多一点：_PFBatchFaultingArray objectAtIndex:
