How to delete a cell in UITableView by using custom button in cell?

I 开发者_JAVA百科have UITableView. I customized the cell height (80.0f).

I have 4 labels(UILabel) and 1 image(UIImage) and 3 buttons (UIButton). one of the button is delete button. By touching the cell or button(play button) on the image a video is loaded and played.

I need to delete the cell by touching delete button. I wrote a selector for delete button. I can delete the video from the library. But how to delete the cell from the table ?

Thank you. The following image shows the delete button of my program.

If your model is updated as you say, use this method on the table view to remove the cell with animation:

- (void)deleteRowsAtIndexPaths:(NSArray *)indexPaths
              withRowAnimation:(UITableViewRowAnimation)animation

http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UITableView_Class/Reference/Reference.html#//apple_ref/occ/instm/UITableView/deleteRowsAtIndexPaths:withRowAnimation:

The table view will clean up the cell for you.

Note that the commitEditingStyle: method is only called when the tableview's delete button (the one you get via editing mode or swipe-to-delete) is touched. From your question it sounds like you have a custom button which is why this method is not called. You could call it yourself but I wouldn't recommend it since it should only be called by the tableview itself.

I got the solution when I did this.

-(void)deleteClicked:(id)sender
{
    UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
    clickedButtonPath = [self.tableView indexPathForCell:clickedCell];

    NSArray *arrayDelete = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectoryD = [arrayDelete objectAtIndex:0]; 

    NSDictionary *dictOfplist1 = [contentArray objectAtIndex:clickedButtonPath.row];

   //To remove the videos from Documents folder       
    NSString *pathTemp1  = [documentsDirectoryD stringByAppendingString:[dictOfplist1 objectForKey:@"fileVideoE"]];
    BOOL succeed1 = [[NSFileManager defaultManager] removeItemAtPath:pathTemp1 error:nil];

   //To remove the images shown in cell from Documents folder.  
    NSString *pathTemp2  = [documentsDirectoryD stringByAppendingString:[dictOfplist1 objectForKey:@"fileImageE"]];
    BOOL succeed2 = [[NSFileManager defaultManager] removeItemAtPath:pathTemp2 error:nil];

   //To remove the data from the plist which is in Documents folder.
    NSString *pathDelete = [documentsDirectoryD stringByAppendingString:@"/details.plist"];
    [contentArray removeObjectAtIndex:[clickedButtonPath row]];
    [contentArray writeToFile:pathDelete atomically: YES];

    //To reload the data of the plist after deleting the items from it.
 [self.tableView reloadData];
}     

Every thing was fine the cell is removed, the data in the plist is removed the videos and images in Documents folder are removed.

Here is the image when I delete the 2nd row.
Thank You.

Call:

[self.tableView reloadData];

You need to do some research on the MVC idiom.
