How to store NSMutableArray to NSUserDefaults and show results in TableView? - objective-c

Question

I want to save the Notifications which come from server in my application and also make a User Interface to give users the ability of chosing which Notification(message) to read. In a scheduled method my client controls for changes inside the server and the communication is in JSON format. I have parsed it and can see the results in NSLog(#"....",..) too. I also control the status of message from the server, if the status equals to 1 i will save the message and add a node to TableView.. Now, can anyone help me about how to transmit datas in NSMutableArray both to NSUserDefaults and TableView? I can Share code or JSON representation too if you want..
It will be better if you could explain with some code.. Thanks
I decided to share some of my code,
as i have writen under the code too, i want to display NSMutableArray in UITableView
`-(IBAction)Accept:(id)sender
{ userName=[[NSString alloc] initWithString:userNameField.text ];
[userNameField setText:userName];
NSUserDefaults *userNameDef= [NSUserDefaults standardUserDefaults];
[userNameDef setObject:userName forKey:#"userNameKey"];

[passwordField setText:password];
NSUserDefaults *passDef=[NSUserDefaults standardUserDefaults];
[passDef setObject:password forKey:#"passwordKey"];

[serverField setText:serverIP];

[serverDef setObject:serverIP forKey:#"serverIPKey"];

NSMutableArray *status = [NSMutableArray array];
// i logged here and it saves the data, now i want to display my data in table view

Answer 1

save it in NSUserDefaults:
[[NSUserDefaults standardUserDefaults]setObject:yourArray forKey:#"theArray"];
get it from NSUserDefaults:
[[NSUserDefaults standardUserDefaults]objectForKey:#"theArray"];
setting values from an array to UITableViewCell:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"TheCell";
UITableViewCell *_cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (_cell == nil) {
_cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
_cell.textLabel.text = [yourArray objectAtIndex:indexPath.row];
return _cell;
}
Hope it helps

don't have a Mac nearby at the moment, so my answer might be a bit sloppy.
In your header file don't forget to add UITableViewDelegate and UITableViewDataSource, so it will look somewhat like that:
#interface yourController : UIViewController <UITableViewDelegate, UITableViewDataSource, ... some others if you need it ...> {
then in the implementation file(.m) you can just start typing
-tableview
and then use the autocompletion to get the methods that you need. You will most probably need these 3:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView: (UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath
depending on the needs of your app you might need more of them, but these 3 should be there.
