how do we access values stored in NSMutableArray of NSMutableDictionary ?
- by srikanth rongali
I have stored values in NsMutableDictionaries . ThenI stored all the dictionaries in NSMutable Array. I need to access the values ? How can I do that ?
-(void)viewDidLoad
{
[super viewDidLoad];
self.title = @"Library";
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)];
cells = [[NSMutableArray alloc] initWithObjects:@"dict1", @"dict2", @"dict3", @"dict4", @"dict5", @"dict6", nil];
dict1 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 01 Feb #2", @"date", @"0.7", @"time", @"1.2MB", @"size", @"200*200", @"pix", nil];
dict2 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Wed, 02 Mar #3", @"date", @"1.2", @"time", @"2.2MB", @"size", @"300*300", @"pix", nil];
dict3 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Tue, 03 Apr #5", @"date", @"1.7", @"time", @"2.5MB", @"size", @"240*240", @"pix", nil];
dict4 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 01 Feb #2", @"date", @"0.7", @"time", @"1.2MB", @"size", @"200*200", @"pix", nil];
dict5 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 10 Nov #5", @"date", @"2.7", @"time", @"4.2MB", @"size", @"200*400", @"pix", nil];
dict6 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 11 Dec #6", @"date", @"4.7", @"time", @"2.2MB", @"size", @"500*200", @"pix", nil];

// Set up the cell...
[(UILabel *)[cell viewWithTag:tag1] setText:[cells objectAtIndex:[dict1 objectForKey: @"date"]]];

cell.imageView.image = [UIImage imageNamed:@"image2.png"];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 80.0f;
}
I did in above way but it is not working. I know the mistake is at the accessing values. but, I could not get how to do it ?
Thank You.
