替換NSMutableDicitionary中的值，它位於NSMutableArray內部

-1

我有一個NSMutableArray，它構成了包含或保存NSMutableDictionary的NSMutableArray。替換NSMutableDicitionary中的值，它位於NSMutableArray內部

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; 
self.userNameArray = [NSMutableArray arrayWithArray:[userDefaults arrayForKey:@"userNameTextArray"]]; 

NSMutableArray *arrayToAdd = [[NSMutableArray alloc] init]; 
for (id object in self.userNameArray) { 
    [arrayToAdd addObject:@"Negative"]; 
} 

self.namesDictionary = [@{ @"userNameText" : self.categoriesMutableNameArray, @"selectedCellState" : arrayToAdd}mutableCopy]; 

self.namesFinalArr = [[NSMutableArray alloc] init]; 
self.namesDictMutableDict = [NSMutableDictionary dictionaryWithDictionary:self.namesDictionary]; 
[self.namesFinalArr addObject:self.namesDictMutableDict];

結果在我上面的代碼NSLog的是這樣的：

(
    { 
    selectedCellState =   (
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative, 
     Negative 
    ); 
    userNameText =   (
     "userText - Text", 
     "userText1 - Text1", 
     "userText2 - Text2", 
     "userText3 - Text3", 
     "userText4 - Text4", 
     "userText5 - Text5", 
     "userText6 - Text6", 
     "userText7 - Text7", 
     "userText8 - Text8", 
     "userText9 - Text9", 
     "userText10 - Text10", 
     "userText11 - Text11", 
     "userText12 - Text12", 
     "userText13 - Text13" 
    ); 
} 
)

我使用一個UITableView和我填充self.namesFinalArr的UITableView的。在這樣的CellForRow方法和它的工作原理：

labelForTableCell.text = [[[self.namesFinalArr objectAtIndex:0] objectForKey:@"userNameText"]objectAtIndex:indexPath.row];

這種填充我與userNameText下的數據的UITableView在self.namesFinalArr

我試圖啓用或細胞禁用圖像時被選中，我把它使用didDeselectRowAtIndexPath和didSelectRowAtIndexPath方法的方法來顯示和隱藏UImageview

這工作，但我想更新self.namesFinalArr在被按下的索引列或行selectedCellState但我得到下面的錯誤。

在didselectRowAtIndexPath方法我做這樣的事情：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
     self.selectedRows = [self.tableView indexPathsForSelectedRows]; 

     [[[[self.namesFinalArr objectAtIndex:0] objectForKey:@"selectedCellState"]objectAtIndex:indexPath.row] setValue:@"Positive" forKey:@"selectedCellState"]; 

}

當試圖改變數組值和索引行我得到一個錯誤：

 Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFConstantString 0x23fef0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key selectedCellState.'

此Log是哪個數組？ – preetam

self.namesFinalArr – user3110353

在這種情況下，有一個數組包含兩個字典中的每一個都包含數組，並且您想要更改數組中的值，並且應該使用此方法更改值

[[[self.namesFinalArr objectAtIndex:0] objectForKey:@"selectedCellState"] replaceObjectAtIndex:indexPath.row withObject:@"Positive"];
