私のアプリケーションには、あまりにも頻繁に更新され、クラッシュし、次のスタック トレースを取得する NSOutlineview があります。

これは私が得ているアサーションです、
*** Assertion failure in -[MyCustomOutlineView _expandItemEntry:expandChildren:startLevel:], /SourceCache/AppKit/AppKit-1187.34/TableView.subproj/NSOutlineView.m:1309

どうすればデバッグできますか
シナリオの編集
これはクライアント -- サーバー アプリケーションです。
Client will listen from a Socket in a **thread, and data will come in XML Format**
In the same thread it will Extract the XML Data and Form a NSMutableDictionary & NSMutableArray
something like this,
NSMutableArray *rootArray = will contain all first level of item,
each element of rootArray will be of type OutlineViewData class, this will contain any additional info whether they are single element or it can be another group item ,
if at all they are group item again there will be an array and so on..
**From listen thread i am calling OutlineView reload data over main thread.**
私が疑っているのは
こうなってます、
void SocketListenerThread(){
while ( hasData ){
if ( xmlOutLineData ){
pData = Make Outline Data ; // This is modifying the Data which will be
// display/used by the NSOutlineView
}
[ Call To Reload the NSOutlineView on the main thread ]
}
}
私は NSOutlineView reloadData が呼び出しをブロックしていると予想していましたが、呼び出しをブロックしていないようです。
NSOutlineView reloadDataのblockingBehaviorを持つ方法はありますか 事前に感謝..
