ios - iOS 中 NSmutableArrays 的 NSMuatableArray 的 RemoveObjectAtIndex 正在崩溃

我正在使用 NSMutableArray 并尝试从 NSMutableArray 中删除对象，然后它崩溃了

[[self.sectionsArray objectAtIndex:indexPath.section] removeObjectAtIndex:indexPath.row];

.h 就像

NSMutableArray *sectionsArray;
@property (nonatomic, retain) NSMutableArray *sectionsArray;



.m is like:

 @synthesize sectionsArray;

 #pragma mark - TableView Delegate

 - (void)tableViewUITableView *)tableView didSelectRowAtIndexPathNSIndexPath *)indexPath
 {
// Perform segue to candy detail
  
NSLog(@"section: %d row: %d", indexPath.section, indexPath.row);
NSLog(@"section :%@", [[self.sectionsArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]);
[[self.sectionsArray objectAtIndex:indexPath.section] removeObjectAtIndex:indexPath.row];
//    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];
  
 }

崩溃日志是这样的:

 2014-01-28 11:56:24.989 CandySearch[828:c07] section: 2 row: 0
 2014-01-28 11:56:24.991 CandySearch[828:c07] section :<Candy: 0x75a5a70>

 libc++abi.dylib: terminate called throwing an exception

我可以看到该索引处的对象。但它仍然崩溃 为什么？

Best Answer-推荐答案

位于索引“indexPath.section”上的数组是一个 NSArray 对象，而不是一个 NSMutableArray 只需阅读崩溃日志: NSArrayI removeObjectAtIndex:

请检查你的sectionArray的对象
