搜索顯示控制器在返回結果時崩潰

我有一個帶有搜索顯示控制器的tableview。它過去一直很好，但最近已經開始崩潰某些搜索結果。在這裏，我的代碼根據他們的姓名，年齡和障礙搜索高爾夫球員。數據被正確加載到表格中，我可以訪問和深入查看以獲取更多信息。但是，當我輸入名稱或年齡的搜索查詢時，應用程序崩潰，而高爾夫球手障礙返回正常。搜索顯示控制器在返回結果時崩潰

注：dataSouceArray是用於實現代碼如下數據源，dataSourceArrayCopy是用於在搜索過濾器添加和刪除對象的數據的可變副本。

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope{ 
    /* 
    Update the filtered array based on the search text and scope. 
    */ 

    [self.dataSourceArrayCopy removeAllObjects]; // First clear the filtered array. 

    /* 
    Search the main list for products whose type matches the scope (if selected) and whose name matches searchText; add items that match to the filtered array. 
    */ 
    for (Golfer *golfer in dataSourceArray){ 
     if ([scope isEqualToString:@"Name"] || [golfer.golferName isEqualToString:scope]){ 
      NSComparisonResult result = [golfer.golferName compare:searchText 
                  options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) 
                  range:NSMakeRange(0, [searchText length])]; 
      if (result == NSOrderedSame){ 
       [self.customerListCopy addObject:golfer]; 
      } 
     } 
     if ([scope isEqualToString:@"Age"] || [golfer.golferAge isEqualToString:scope]){ 
      NSComparisonResult result = [golfer.golferAge compare:searchText 
                  options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) 
                  range:NSMakeRange(0, [searchText length])]; 
      if (result == NSOrderedSame){ 
       [self.dataSourceArrayCopy addObject:golfer]; 
      } 
     } 
     if ([scope isEqualToString:@"Handicap"] || [golfer.golferHandicap isEqualToString:scope]) 
     { 
      NSComparisonResult result = [golfer.golferHandicap compare:searchText 
                   options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) 
                   range:NSMakeRange(0, [searchText length])]; 
      if (result == NSOrderedSame) 
      { 
       [self.dataSourceArrayCopy addObject:golfer]; 
      } 
     } 
    } 
} 
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString 
{ 
    [self filterContentForSearchText:searchString scope: 
    [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]]; 

    // Return YES to cause the search result table view to be reloaded. 
    return YES; 
} 


- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption 
{ 
    [self filterContentForSearchText:[self.searchDisplayController.searchBar text] scope: 
    [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]]; 

    // Return YES to cause the search result table view to be reloaded. 
    return YES; 
}

任何幫助將不勝感激，感謝您花時間閱讀此。

粗略一瞥，我沒有看到任何明顯的錯誤。您需要設置斷點並逐步瀏覽代碼，以查找崩潰併發布的確切行。 – TechZen 2010-03-18 15:09:26

將來，請勿在代碼中使用製表符來縮進格式。 – TechZen 2010-03-18 15:20:28

謝謝你看看，我會稍後再報告。 – Convolution 2010-03-18 15:26:32

奇怪的是，當在另一個開發人員手機上測試完全相同的代碼時，它並沒有使程序崩潰。沒有太多的答案，但讓這成爲每個人的教訓，在多個設備上進行測試。
