Objective c removeObjectAtIndex使应用程序崩溃

在.h文件中，我设置了以下行

  NSMutableArray *repArray;   

在.m文件中，我放置了以下几行。（我只放置了此ex所需的代码行） -（无效）从数据库中读取数据 { objectsForCharacters=[[NSMutableDictionary alloc]init]

sqlite3 *db = [contactAppDelegate getNewDBConnection];

NSMutableString *query = nil;

query = [NSMutableString stringWithFormat:@"select representative, title, business_name, uid from corporate where profiler_type <> 'OWN_CORPORATE' order by representative asc"];  

const char *sql = [query UTF8String];
sqlite3_stmt *selectAllStmt = nil;

if(sqlite3_prepare_v2(db,sql, -1, &selectAllStmt, NULL)!= SQLITE_OK)
    NSAssert1(0,@"error preparing statement",sqlite3_errmsg(db));
else
{
    repArray = [[NSMutableArray alloc]init];
    businessArray = [[NSMutableArray alloc]init];
    titleArray = [[NSMutableArray alloc]init];
uidArray = [[NSMutableArray alloc]init];

    while(sqlite3_step(selectAllStmt)==SQLITE_ROW)
    {


        char *chrstr =(char *)sqlite3_column_text(selectAllStmt, 0);
        if(chrstr !=NULL)
        {
            corpRepresentative = [NSString stringWithUTF8String:chrstr];
            [repArray addObject:corpRepresentative];
        }       
        chrstr =(char *)sqlite3_column_text(selectAllStmt, 1);
        if(chrstr !=NULL)
        {

            corpTitle = [NSString stringWithUTF8String:chrstr];
            [titleArray addObject:corpTitle];
        }
        chrstr =(char *)sqlite3_column_text(selectAllStmt, 2);
        if(chrstr !=NULL)
        {
            corpBusiness_name = [NSString stringWithUTF8String:chrstr];
            [businessArray addObject:corpBusiness_name];

        }   

        chrstr =(char *)sqlite3_column_text(selectAllStmt, 3);
        if(chrstr !=NULL)
        {
            corporteUid = [NSString stringWithUTF8String:chrstr];
            [uidArray addObject:corporteUid];

        }


    }


}
sqlite3_finalize(selectAllStmt);

sqlite3_close(db);

}

我正在尝试从方法中删除数组元素。如果我执行以下命令，则应用程序会在我的iPod Touch中自动崩溃。但它在模拟器中运行良好，没有任何错误

[repArray removeObjectAtIndex:selectedIndexPath.row];

或

---

即使我的数组中有多个元素，这两个元素都会使应用程序崩溃。

当你的应用程序像那样崩溃时，99%的时间你都在试图删除超出数组边界的对象。

错误消息是什么？@Philippe Sabourin我真的不知道如何接受我前面问题的答案。@Benj我没有收到任何错误消息。它在模拟器中运行良好，没有错误。但不是在iPod@dinesh看起来你已经明白了：）83%要好得多。可能是的，但为什么我会有这个问题在模拟器中并不存在。彼得，你能帮我一下吗？我可以尝试-但你需要发布更多的代码-在你创建数组的地方，以及在从数组中删除对象的上下文中发布更多的代码。另外，您是否检查了indexPath.row是否小于数组对象计数？Peter我已经为您上传了其他代码。请看一看。我确信问题出在removeObjectAtIndex中。然后请上传实际相关的代码。应用程序崩溃的整个函数，以及调试器显示的错误消息。
