这是示例代码：

 NSArray *postDupe = [[_postsArray valueForKeyPath:@"@unionOfArrays.@allValues"] valueForKeyPath:@"post"];

 NSArray *foundArray = nil;

 predicate = [NSPredicate predicateWithFormat:@"post_id.stringValue contains [c] %@",@"18586"];

 foundArray = [postDupe filteredArrayUsingPredicate:predicate];

 long foundIndex = 0;
        long count = 0;
        for (int i=0; i<foundArray.count; i++)
        {
            foundIndex = [postDupe indexOfObject: [foundArray objectAtIndex: i]];
            //NSLog(@"%@ is at index %d", string, index);
            }
        _filterPostsArray = [_postsArray objectAtIndex:foundIndex];


        }
    searchActive = YES;
    dispatch_async(dispatch_get_main_queue(),^{
        [_issuesTable reloadData];
    });

示例Json数据：

        14556 =     {
            newCommentsCount = 0;

[__ NSDictionaryM safeObjectAtIndex：]：无法识别的选择器发送到实例

看起来你有一本字典并且把它当成一个数组。

在调试器中运行代码并在算法中检查变量的值，这应该会显示出错的地方。

<强>猜测：

谓词post_id.stringValue中的关键路径应为post.post_id.stringValue - 您的词典包含一个键post，其值本身就是一个具有键post_id的词典。
_filterPostsArray = [_postsArray objectAtIndex:foundIndex]听起来像是在为数组分配字典。您可能希望此语句在循环中并将字典添加到数组中作为新元素吗？
