NSArray With NSString Is This Even Possible? - iphone

Question

I am trying to build a Grouped Sectioned View. I want to set an array as an object in the dictionary but I came across the empty array Issues.
Is this Even possible????? Is There a trick ????
#import "RootViewController.h"
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
// Get the specific Node for this row.
Nodes *nodes = (Nodes *)[nodesMArray objectAtIndex:indexPath.row];
// Create the Details View Controller and initialize it.
nodesDetailView *viewController = [[nodesDetailView alloc] initWithStyle:UITableViewStyleGrouped ];
[[self navigationController] pushViewController:viewController animated:YES];
// Set the title of the view to the nodes name
viewController.title = [nodes computer_name];
//Information
//Network Data
viewController.ipaddress= [nodes ipaddress];
viewController.subnet_mask= [nodes subnet_mask];
viewController.gateway= [nodes gateway];
viewController.domain_name= [nodes domain_name];
}
#import "nodesDetailViewController. h
#interface nodesDetailView : UITableViewController{
//Network Data
NSString *ipaddress;
NSString *subnet_mask;
NSString *gateway;
NSString *domain_name;
//Grouped
NSMutableArray *Keys;
NSMutableDictionary *Contents;
}
#property (nonatomic, retain) NSMutableArray *Keys;
#property (nonatomic, retain) NSMutableDictionary *Contents;
#property (nonatomic, retain) NSString *ipaddress;
#property (nonatomic, retain) NSString *subnet_mask;
#property (nonatomic, retain) NSString *gateway;
#property (nonatomic, retain) NSString *domain_name;
#end
#import "nodesDetailViewController. m
#synthesize .......
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
NSMutableArray *keys = [[NSMutableArray alloc] init];
NSMutableDictionary *contents = [[NSMutableDictionary alloc] init];
NSString *network = #"Network Data";
NSString *product = #"Product Details";
//IS THIS POSSIBLE ??????? Because I get An Empty array
[contents setObject:[NSArray arrayWithObjects: ipaddress,subnet_mask, gateway, domain_name, nil] forKey:network];
return self;
}
Thank You In Advance.

Answer 1

All of those strings that you are adding to the array haven't even been allocated/initialized yet. That's why the array is empty. You can't just go: NSString *emptyString; and then go: [myArray addObject:emptyString];. Your strings are all empty.

Check the values u are passing from the table view. They maybe nil. I just used this much of data and i m getting correct NSLog.
NSMutableDictionary *contents = [[NSMutableDictionary alloc] init];
NSString *my = #"kk";
NSString *my1 = #"polko";
[contents setObject:[NSArray arrayWithObjects: my1,my, nil] forKey:#"o"];
NSLog(#"%#" , contents);

For Those Who are wondering: Problem Solved My code was fine. the problem was :
it was in the wrong place.
The Code Supposed to be in - (void)viewDidLoad and not in - (id)initWithStyle:
I want to thank everybody who took the time to look in to it.
I have no idea why i put the code there to begin with.
Thanx Again
