只有當填充另一個數組時，NSMutableArray纔會出現界限

Question

所以我有一個UItableView，它根據用戶輸入自動填充單元格。我有一個名爲arrColors的顏色名稱的主數組，以及一個名爲arrAutoCorrect的「temp」數組，當用戶輸入時會填充該數組。

這兩個數組都是NSMutableArrays。

如果用戶清除所有文本，則應從所有顏色中完全加載臨時數組。 顏色數組中有21種顏色（字符串）。

我得到一個索引超出界限17（0 - 16）的錯誤。

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 17 beyond bounds [0 .. 16]' 

這讓我瘋狂。

這17個來自哪裏？當用戶清除文本框的所有內容時，該錯誤只會再次顯示。

我NSLogged幾乎所有我可以，我找不到什麼調用這個17範圍內。

我的代碼

- (void)searchAutocompleteEntriesWithSubstring:(NSString *)substring :(NSMutableArray*) passedArray { 

    [self.arrAutoComplete removeAllObjects]; 

    if ([substring length] == 0) { 
     //add all items 
     int count = 0; 
     for (NSString* c in passedArray) { 
      NSLog(@"Count: %i", count); 
      [self.arrAutoComplete addObject:c]; 
      count++; 
     } 

    } else { 
     //Narrow down 
     for(NSString *curString in passedArray) { 
      NSRange substringRange = [curString rangeOfString:substring options:NSCaseInsensitiveSearch]; 
      NSLog(@"my range is %@", NSStringFromRange(substringRange)); 
      if (substringRange.location == 0) { 
       [self.arrAutoComplete addObject:curString]; 
      } 
     } 

    } 
    [self.autocompleteTableView reloadData]; 
} 



#pragma mark - TABLE VIEW DELEGATES 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 

     // Return the number of sections. 
     //NSLog(@"Number of sections to call for autocomplete table is: 1"); 
     return 1; 

} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 


     // NSLog(@"Number of rows in section for autocomplete is: %lu", (long)[self.arrAutoComplete count]); 
     return [self.arrAutoComplete count]; 



} 


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    UITableViewCell *cell = nil; 
    //NSLog(@"Default cell delegate called"); 
    NSUInteger section = [indexPath section]; 
    // NSLog(@"Section: %lu", (unsigned long)section); 

    NSUInteger row = [indexPath row]; 
    NSLog(@"Row : %lu", (unsigned long)row); 


     //NSLog(@"Cell for autocomplete called"); 

     static NSString *AutoCompleteRowIdentifier = @"AutoCompleteRowIdentifier"; 
     cell = [tableView dequeueReusableCellWithIdentifier:AutoCompleteRowIdentifier]; 
     if (cell == nil) { 
      //NSLog(@"Cell for autocomplete was nil, createing new"); 
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AutoCompleteRowIdentifier]; 
     } 

     //NSLog(@"Indes path row: %lu", indexPath.row); 
     cell.textLabel.text = [self.arrColors objectAtIndex:row]; 
     //NSLog(@"Cell for autocomplete text should be: %@",[self.arrColors objectAtIndex:indexPath.row]); 



    return cell; 
}

附加信息： 如果我註釋掉所有的顏色searchAutocompleteEntriesWithSubstring其中子長度爲0的加入，則應用程序不會崩潰。

更新解決

我缺少的方法：

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { 
    return 60.0f;//some random number 
} 

請務必閱讀您的文件，小子。

Answer 1

我缺少的方法：

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { 
    return 60.0f;//some random number 
} 

即使我使用的是靜態的細胞，（這並不需要tableView:heightForRowAtIndexPath），動態表一樣。
