    text
    copied!<p>I'm trying to add a cell to my table view controller from a modal view controller. My data source array has multiple properties (name, time interval). Right now I have a delegate/protocol in my modal view controller that sends the data to the table view controller. However, for some reason I can add the data to the array but I can't add a cell to the tableview with that data. Here is my code:</p> <p>ToDoTableViewController.h (TableViewController)</p> <pre><code> @interface ToDoTableViewController : UITableViewController &lt;UITableViewDataSource, Properties2ViewControllerDelegate&gt; { IBOutlet UIView *headerView; } @property (strong, nonatomic) NSMutableArray *taskArray; -(UIView *)headerView; -(IBAction)addCell:(id)sender; </code></pre> <p>ToDoTableViewController.m (TableViewController)</p> <pre><code>-(void) viewDidLoad{ [[self tableView] setDataSource:self]; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"]; if (!cell) cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"]; [[cell textLabel] setText:[taskArray objectAtIndex:[indexPath row]]]; return cell; } -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return [taskArray count]; } -(IBAction)addCell:(id)sender{ Properties2ViewController *pvc = [[Properties2ViewController alloc]init]; [pvc setDelegate:self]; [self presentViewController:pvc animated:YES completion:NULL]; } -(UIView *)headerView{ if (!headerView){ [[NSBundle mainBundle] loadNibNamed:@"HeaderView" owner:self options:nil]; } return headerView; } -(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{ return [self headerView]; } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{ return [[self headerView] bounds].size.height; } -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [[self tableView] reloadData]; } -(void)properties2ViewControllerDidEnterPropertiesSuccesfully:(Tasks *)t{ [taskArray addObject:t]; } </code></pre> <p>Properties2ViewController.h (ModalViewController)</p> <pre><code> @class Tasks; @protocol Properties2ViewControllerDelegate; @interface Properties2ViewController : UIViewController &lt;UITextFieldDelegate&gt;{ __weak IBOutlet UITextField *taskName; __weak IBOutlet UIButton *doneButton; __weak IBOutlet UIDatePicker *datePicker; __weak IBOutlet UILabel *label1; __weak IBOutlet UILabel *label2; } @property (strong, nonatomic) Tasks *testTask; @property (weak, nonatomic) id &lt;Properties2ViewControllerDelegate&gt; delegate; -(IBAction)dismiss:(id)sender; -(IBAction)cancel:(id)sender; @end @protocol Properties2ViewControllerDelegate &lt;NSObject&gt; @optional -(void)properties2ViewControllerDidEnterPropertiesSuccesfully:(Tasks *)t; @end </code></pre> <p>Properties2ViewController.m (ModalViewController)</p> <pre><code>-(IBAction)dismiss:(id)sender{ testTask = [[Tasks alloc]initWith:[taskName text] :[datePicker countDownDuration] :[NSDate date]]; if ([self.delegate respondsToSelector:@selector (properties2ViewControllerDidEnterPropertiesSuccesfully:)]){ [self.delegate properties2ViewControllerDidEnterPropertiesSuccesfully:testTask]; } [self dismissViewControllerAnimated:YES completion:NULL]; } -(void)viewWillDisappear:(BOOL)animated{ [super viewWillDisappear:animated]; } -(BOOL) textFieldShouldReturn:(UITextField *)aTextField{ if (aTextField.tag == 1){ [taskName resignFirstResponder]; } return YES; } -(void)viewDidDisappear:(BOOL)animated{ [super viewDidDisappear:animated]; } -(IBAction)cancel:(id)sender{ [self dismissViewControllerAnimated:YES completion:NULL]; } @end </code></pre> <p>Here are the properties of the Task class...if it helps at all...</p> <pre><code>@interface Tasks : NSObject @property (strong, nonatomic) NSString *taskName; @property NSTimeInterval timeInterval; @property NSDate *dateCreated; -(id)initWith:(NSString *)tskNme :(NSTimeInterval)timeInt :(NSDate *)dateCreat; @end </code></pre> <p>---EDIT----- So I tried putting this in my properties2ViewControllerDidEnterPropertiesSuccesfully delegate method but the cell is still not being created...:</p> <pre><code>-(void)properties2ViewControllerDidEnterPropertiesSuccesfully:(Tasks *)t{ [taskArray addObject:t]; [self.tableView reloadData]; int lastRow = [[self tableView] numberOfRowsInSection:0]; NSIndexPath *ip = [NSIndexPath indexPathForItem:lastRow inSection:0]; [self.tableView cellForRowAtIndexPath:ip]; } </code></pre> <p>Also, if i switch </p> <pre><code>[self.tableView cellForRowAtIndexPath:ip]; </code></pre> <p>with</p> <pre><code>[self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:ip] withRowAnimation:UITableViewRowAnimationTop]; </code></pre> <p>then an exception is thrown (Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'attempt to insert row 0 into section 0, but there are only 0 rows in section 0 after the update')</p>
