Ios 如何在PFQueryTableView编辑模式下添加新的插入行？

我想知道如何在

PFQueryTableView

中添加新的插入行。我的表视图工作正常，可以正确加载所有PFObject。但是，我想在表视图底部添加一个新行，这样当我单击该行时，它将弹出另一个视图控制器来创建一个新的

PFObject

。由于

PFQueryTableViewController

附带了其

编辑按钮

，该按钮仅允许删除PFObject。你能帮我吗

视图内加载

在-表视图中：行数部分：

In-tableView:cellForRowAtIndexPath:对象：

---

按照您描述的方式进行操作的问题是没有相应的

PFObject

传递到

tableView:cellForRowAtIndexPath:object:

方法。这可能会导致问题。此外，用户必须滚动到底部才能访问添加按钮

一个更好的方法（我也是这样做的，因为我的应用程序就是这样做的）就是在导航栏上添加另一个按钮

在

viewDidLoad

或自定义

init

方法中：

// Make a new "+" button
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addButtonPressed)];
NSArray *barButtons = [NSArray arrayWithObjects:self.editButtonItem,addButton,nil];
self.navigationItem.rightBarButtonItems = barButtons;

// The user pressed the add button
MyCustomController *controller = [[MyCustomController alloc] init];
[self.navigationController pushViewController:controller animated:YES];
// Replace this with your view controller that handles PFObject creation

- (void) setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];
    if(editing)
    {
        UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addButtonPressed)];
        // self.editButtonItem turns into a "Done" button automatically, so keep it there
        NSArray *barButtons = [NSArray arrayWithObjects:self.editButtonItem,addButton,nil];
        self.navigationItem.rightBarButtonItems = barButtons;
    }
    else
        self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

然后在

addButtonPressed

方法中：

// Make a new "+" button
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addButtonPressed)];
NSArray *barButtons = [NSArray arrayWithObjects:self.editButtonItem,addButton,nil];
self.navigationItem.rightBarButtonItems = barButtons;

// The user pressed the add button
MyCustomController *controller = [[MyCustomController alloc] init];
[self.navigationController pushViewController:controller animated:YES];
// Replace this with your view controller that handles PFObject creation

- (void) setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];
    if(editing)
    {
        UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addButtonPressed)];
        // self.editButtonItem turns into a "Done" button automatically, so keep it there
        NSArray *barButtons = [NSArray arrayWithObjects:self.editButtonItem,addButton,nil];
        self.navigationItem.rightBarButtonItems = barButtons;
    }
    else
        self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

如果您只希望用户能够在编辑模式下创建新对象，请将逻辑移到

setEditing:animated:

方法：

// Make a new "+" button
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addButtonPressed)];
NSArray *barButtons = [NSArray arrayWithObjects:self.editButtonItem,addButton,nil];
self.navigationItem.rightBarButtonItems = barButtons;

// The user pressed the add button
MyCustomController *controller = [[MyCustomController alloc] init];
[self.navigationController pushViewController:controller animated:YES];
// Replace this with your view controller that handles PFObject creation

- (void) setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];
    if(editing)
    {
        UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addButtonPressed)];
        // self.editButtonItem turns into a "Done" button automatically, so keep it there
        NSArray *barButtons = [NSArray arrayWithObjects:self.editButtonItem,addButton,nil];
        self.navigationItem.rightBarButtonItems = barButtons;
    }
    else
        self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

希望有帮助！这是我做这件事的方式（某种程度上），在我看来，这比在tableView底部的单元格内有一个按钮要干净一些
