Load information from text field to table view - objective-c

Question

Hi I am trying to make an app that has a text field, tableview and a button.
When you press the button it adds the information from the text field to de tableview.
Do any one know when I can find a tutorial for this? I had one on a book but I cant find it.
Thanks in advance.
Here is my code so far:
code of .h
#interface BlockNotasViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> {
IBOutlet UITableView *tableNota;}
#property (strong, nonatomic) IBOutlet UITextField *textonota;
#property (nonatomic, retain) IBOutlet UITableView *tableNota;
#property (nonatomic, strong) NSMutableArray * arrayNota;
- (IBAction)AddNota:(id)sender;
#end
code of .m
- (void)viewDidLoad{
[super viewDidLoad];
self.textonota.delegate = self;
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return NO;
}
- (IBAction)AddNota:(id)sender {
[arrayNota addObject: textonota.text];
[tableNota reloadData];
}
//TableView------------------------------------
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [arrayNota count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (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] init];
}
cell.textLabel.text = [arrayNota objectAtIndex: indexPath.row];
return cell;
}
//----------------------------------------------
#end
No more errors but the button doesnt do anything

Answer 1

You can set up a NSMutableArray property that contains all the cells you want to add to the tableView.
When that button is pressed, you create a cell with a tag, and set text of that cell to the text of your UITextField:
cell.textLabel.text = aUITextField.text;
then add the cell into that NSMutableArray, and call [tableView reloadData] to refresh the table view.
In cellForRowAtIndexPath:indexPath delegate, you can use that tag to determine which cell in NSMutableArray to return, for example:
[return [self.cellArray objectAtIndex:indexPath.row]];
Hope this helps! :)

You should keep mutable array with strings. And use this array for fill content of tableview as data source. In delegate method - (UITableViewCell*) tableView:cellForRowAtIndexPath: you will create UITableViewCell if needed like this:
- (UITableViewCell*) tableView: (UITableView*) tableView
cellForRowAtIndexPath: (NSIndexPath*) indexPath
{
UITableViewCell* cell = [tableViewdequeueReusableCellWithIdentifier: #"identifier"];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault
reuseIdentifier: #"identifier"] autorelease];
}
cell.textLabel.text = [myMutableArray objectAtIndex: indexPath.row];
return cell;
}
- (NSInteger)tableView: (UITableView*) tableView numberOfRowsInSection:(NSInteger)section
{
return [myMutableArray count];
}
- (IBAction) pressButton: (id) sender
{
[myMutableArray addObject: textField.text];
[myTableView reloadData];
}
Every book for iOS developers contains information about UITableView.
