array data from other viewcontroller

ahsan123 · 08-23-2011, 01:26 PM

Hello everyone

I have made an application in which I have UITableview and UIView. In UIView I have a text field i which entered data must be save in the UITableView Controller. For this I have done thi:

Code:

Today *today=[[Today alloc]initWithStyle:UITableViewStylePlain];
	AddTasks *add=[[AddTasks alloc]init];
    [today.array insertObject:add.tName.text atIndex:[today.array count]];
	NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];
	[defaults setObject:today.array forKey:@"todayArray"];
	[defaults synchronize];

Note: TodayTasks is UITableView controller and AddTasks is UIView for entering data.

But I am facing failure in this. Can any one help me.

Thanks

You're going to have to be a bit more descriptive.... what exactly does 'facing failure' mean? Does the app crash? Does it compile? What happens?

no it doesn't crashes. the failure I am facing is "Data is not being entered"

thanks

Well, seeing as you create 'add' one line before you add it to the UITableView, my guess is that the text field is empty (unless your AddView init() call populates the text field with some data).

You'll need to have some data in your text field before you add it to your table view.

Sorry I did not understand please can you explain please. I do put text in textfield but even then it does not put into the array of UITableView List.

for explaining you:
I have done this in array

Code:

	array=[[NSMutableArray array]retain];

This is TableView array. Means Today's page array

The text field you're adding will be nil because you've only just created it, so there's no data to add to your array:

Code:

Today *today=[[Today alloc]initWithStyle:UITableViewStylePlain];
AddTasks *add=[[AddTasks alloc]init];

// *** At this point, the text field of add.tName will be blank because you have only just initialized it with the line above.

[today.array insertObject:add.tName.text atIndex:[today.array count]];

Hello MattW

I haven't just created the textfield. Actually I do put data in text field after running the program but when I check the tableview, it shows empty.
It is not being done with this too. It is not showing the string.

Code:

    [today.array insertObject:@"hello" atIndex:[today.array count]];
