removeObjectAtIndex崩潰應用程序

Question

在.h文件中，我設置了下面的行。

NSMutableArray *repArray; 

在我已放置在下面線.m文件（我把這種前的代碼只是所需的線） - （無效）read_data_fromDB { objectsForCharacters = [[ALLOC的NSMutableDictionary] 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); 

}

我試圖從一個方法刪除一個數組元素。如果我執行下面的行，那麼應用程序會在我的iPod Touch中自動崩潰。但它在模擬器中正常工作沒有任何錯誤。

[repArray removeObjectAtIndex:selectedIndexPath.row]; 

或

[repArray removeObjectAtIndex:0]; 

兩個崩潰，即使我有在陣列多於一個元素的應用程序。

當你的應用程序崩潰時，99％的時間你試圖刪除超出數組邊界的對象。
