iphone - UITableView 编辑模式不工作

Question

我正在尝试激活 UITableView 的编辑模式。当我单击“编辑”按钮时，它变为“完成”，但表格中没有显示圆形红色减号。我在下面发布了该类(class)的一些方法。应用程序委托(delegate)创建了一个选项卡栏，选项卡内的 View 具有导航 Controller 。一切都在代码中完成，很少用 nib 文件完成。怎么了？

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {  
    return [ikub.subscriptions count];  
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {  
    int i = [indexPath row];  
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];  
    if (cell == nil) {  
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];  
    }  
    Subscriptions *s = [ikub.subscriptions objectAtIndex:i];  
    cell.textLabel.text         = [s title];  
    cell.detailTextLabel.text   = [NSString stringWithFormat:@"%@ artikuj te rinj, %@ artikujt te lexuar", [s new], [s read]];  
    if (deleteActive) {  
        cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;  
    } else {  
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;  
    }  
    return cell;  
}  
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {  
    Subscriptions *s = [ikub.subscriptions objectAtIndex:[indexPath row]];  
        NSString *address = [[NSString alloc] init];  
        NSString *type = [NSString stringWithString:[s type]];  
        if ([type isEqualToString:@"Category"]) {  
            address = [NSString stringWithFormat:@"http://www.ikub.al/Rss.aspx?node=9e26cdb8-dba6-4504-8bb6-29f0753be179~%@", [s code]];  
        } else if ([type isEqualToString:@"Tag"]) {  
            address = [NSString stringWithFormat:@"http://www.ikub.al/Rss.aspx?tag=%@", [s code]];  
        }
        address = [address stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];  
        SubscriptionStories *ss = [[SubscriptionStories alloc] init];  
        ss.address = address;  
        ss.title = [s title];  
        [self.navigationController pushViewController:ss animated:YES];  
        [ss release];  
}  
- (void)viewWillAppear:(BOOL)animated {  
    [subscriptionsTable reloadData];  
}  
- (void)viewDidLoad {  
    refreshButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:nil];  
    self.navigationItem.leftBarButtonItem = refreshButton;  
    [refreshButton release];  
    self.navigationItem.rightBarButtonItem = self.editButtonItem;  
    [super viewDidLoad];      
}  
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {    
    return YES;  
}

Answer 1

继承对其没有任何影响。

您可以使用此方法，当您将 navigationController 的右键分配给它时它会起作用。

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
    [super setEditing:editing animated:animated];
    [tableView setEditing:editing animated:YES];
}

或者你可以编写一个基本上切换 UITableView 状态的方法，比如

[tableView setEditing:TRUE];

当按钮完成后，将其切换为

[tableView setEditing:FALSE];
