TableView with TextView. How to add multiple files? (A .txt file each row)

[Ogispert]

I'm a novice in this and I'm trying to develop a little app.

This app is about a table view, with a sub view (another table view), and finally a Text View that opens a .txt file.

My problem is that I want it to display a different .txt file each row, and I only get the same file, no matter witch row I select.

Hope someone can help me.

Thank's a lot in advance.


This is the code I have:


TEXT VIEW CONTROLLER (.M)

#pragma mark - View lifecycle

- (void)viewDidLoad
{
[Article setText:[self textSelected]];
self.title = textSelected;
[super viewDidLoad];

NSString *filepath = [[NSBundle mainBundle] pathForResource:textSelected ofType:@"txt"];
if (filepath) {
NSString *myText = [NSString stringWithContentsOfFile:filepath encoding:NSUTF8StringEncoding error:NULL];
if (myText) {
Article.text = myText;
}
}
}

- (void)viewDidUnload
{
[super viewDidUnload];
self.Article = nil;
}

ANOTHER OPTION TO LOAD THE FILE WAS:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"FILE NAME" ofType:@"txt"];
if (filePath) {
NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
if (myText) {
Article.text = myText;
}

BUT I DON'T KNOW HOW TO POINT A DIFFERENT FILE TO EACH ROW.


THE TABLE VIEW CONTROLLER (.M) LOOKS LIKE THIS:


- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [contenido objectAtIndex:
[indexPath row]];
return cell;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

if (self.articleViewController == nil)
{
ArticleViewController *text = [[ArticleViewController alloc]
initWithNibName:@"ArticleViewController"
bundle:[NSBundle mainBundle]];

self.articleViewController = text;
[text release];
}

[self.navigationController pushViewController:
self.articleViewController animated:YES];
}

It is a table view and when you click a row it goes to a text view with a .txt file.

The problem is that every row displays the same file and I need each row to display a different file.

All file are in the bundle.

I don't know if I have to make a TextViewController (xib) for each row (file), or it is just a matter of my code.

Thank's a lot.

No not require the multiple textviewcontroller.
1. what the table view contain name of file?
2.is yes then in the next view controller send that name and in the opening of file on by that

Sorry, I'm not sure if I understand you:

So, this my code for each file:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"FILE NAME" ofType:@"txt"];
if (filePath) { 
NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; 
if (myText) { 
Article.text = myText; 
}

So You say that I have to send this code for each file?... That's ok, ... But how do I separate each row and file? there is de (if.. else..) code, but I'm not sure how to use it.

I'm sorry if I don't get you right. Do you speak spanish?... yo sí.

thank's a lot.

[ngaikwad]

hi
i don't know Spanish.............

i want to know that in the table what data you store that data is file name or other. and about the data sending when you click on table cell there you can use the filename=[your_array objectatindex:row];

Ok, I've tried using the same data name and then a different one, then I've change from option 1 to option 2, and the only thing that changed was the .txt file, but again, is the same for all rows.

I could send you the entire file if you want.

I would be so glad.

thank's

and i'm sorry if I don't make my self clear.

paste code here [code] tag to paste code

[ngaikwad]

Check that your code is as same as below

1.your table contain the filenames(any file name as u created).........
tablecell1----------a.txt
tablecell1----------b.txt
2.in the class at the method
-(void)tableviewuitableview *)tableview didselectrowatindexpathnsindexpath *)indexpath{
here you may be cal the next view??
if yes then at time calling the view u can send the file name to next view by making string object in next view controller and set the name to that and onpe the file in there viewdidload and show in there view as you make(textview or any other)
}

The problem is that your textviewcontroller loads your article in viewDidLoad and it's only called once as you use a property to keep track of it in your tableView.

make one method in articleviewcontroller to accept filename and in the viewdidload make shure that the text file open and show all data there

so in that way when u click on the table cell there that file name send to next view controller and that file will display

It didn't work just like that...

So, do I need an .xib for each .txt file... or (I'm sorry), I keep miss understanding something.

ej. [articleViewController textfilename:abc.txt]; "abc" is my file name?

sorry, I've spent a lot of time with this and I'm a little frustrated.

No you not require an .xib file for each *.txt file.
Yes the abc is Your file name

and don't frustrated it will solve!!!!!!!!!!!!!!!!!!!

So sorry about this, but, Could you explain that a little more???

Try this. Add line in didSelectRowAtIndexPath:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
        
            //---Navigate to the details view---
            if (self.articleViewController == nil)
            {        
                ArticleViewController *text = [[ArticleViewController alloc] 
                                            initWithNibName:@"ArticleViewController" 
                                            bundle:[NSBundle mainBundle]];
                
                self.articleViewController = text;
                [text release];
            }    
            self.articleViewController.textSelected = [contenido objectAtIndex: 
                               [indexPath row]];
            //---set the state selected in the method of the 
            // DetailsViewController---//
            [self.navigationController pushViewController:
             self.articleViewController animated:YES];
        }
}

Change viewDidLoad, add viewWillAppear in article controller:

- (void)viewDidLoad
{
    //[Article setText:[self textSelected]];
    //self.title = textSelected;
    [super viewDidLoad];
    
	/*NSString *filepath = [[NSBundle mainBundle] pathForResource:textSelected ofType:@"txt"];
    if (filepath) {
        NSString *myText = [NSString stringWithContentsOfFile:filepath encoding:NSUTF8StringEncoding error:NULL];  
        if (myText) {  
            Article.text = myText;  
        }  
    }*/
    
    // Do any additional setup after loading the view from its nib.
}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    NSString *filepath = [[NSBundle mainBundle] pathForResource:textSelected ofType:@"txt"];
    if (filepath) {
        NSString *myText = [NSString stringWithContentsOfFile:filepath encoding:NSUTF8StringEncoding error:NULL];

So sorry about this, but, Could you explain that a little more???

ok.....

In the articleviewcontroller make one method any name which can only store the string .
and this string is you send from table view controller xib file.

and in viewdidload you open the file and show in that xib file(if taken text area then send all file data to there)

if (self.articleViewController == nil)
            {        
                ArticleViewController *text = [[ArticleViewController alloc] 
                                            initWithNibName:@"ArticleViewController" 
                                            bundle:[NSBundle mainBundle]];
                
                self.articleViewController = text;
                [text release];
            }

articleViewController is set as a property. viewDidLoad will only run once (as I mentioned earlier).

Or the loading of the text can be done in viewWillAppear.
