commitEditingStyle 不会被触发 [英] commitEditingStyle is not fired

问题描述

我有一个 UITableView，当编辑模式处于活动状态但未触发 commitEditingStyle 时，我试图删除一行.

I've a UITableView, I am trying to delete a row when editing mode is active but commitEditingStyle is not fired.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

    cell.text=[NSString stringWithFormat:@"Row Number %d",indexPath.row];

    return cell;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"trying to delete a row..");
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 6;
}

-(void)Edit:(id)sender //Active editing mode
{
    [self.table setEditing:YES animated:YES];
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(Done:)];
}

我只想删除一行?

这就是我展示弹出框的方式:

This is how I show my popover:

UIPopoverController *popover;
-(IBAction)open:(id)sender
{
    CGRect r=((UIButton*)sender).frame;
    CGRect tRect=[((UIButton*)sender) convertRect:((UIButton*)sender).frame toView:self.view];
    tRect.origin.x=r.origin.x;

    Popover *firstViewCtrl = [[Popover alloc] init];

    UINavigationController *navbar = [[UINavigationController alloc] initWithRootViewController:firstViewCtrl];
    navbar.preferredContentSize = CGSizeMake(300, 300);
    popover = [[UIPopoverController alloc] initWithContentViewController:navbar];
    popover.delegate = self;
    popover.popoverContentSize = CGSizeMake(300, 300);

    CGRect popRect = CGRectMake(0,
                                0,
                                200,
                                200);

    [popover presentPopoverFromRect:popRect
     inView:self.view
     permittedArrowDirections:UIPopoverArrowDirectionAny
     animated:YES];

   // [popover presentPopoverFromRect:tRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
}

我使用 Xcode 界面创建了 UITableView.

I created UITableView using Xcode interface.

-(void)Done:(id)sender
{
    [self.table setEditing:NO animated:NO];
    //[self.table endEditing:true];
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(Edit:)];
}

推荐答案

它在您触摸 DELETE 按钮时触发，而不是减号...并且 tableview 上的删除按钮不会适当显示到您的 tableview 的宽度...

it fires when you touch DELETE button, not the minus... And delete buttons on your tableview doesn't show propably due to your tableview's width...
