将工具栏添加到UITableViewController [英] Add toolbar to UITableViewController

问题描述

将UIToolBar添加到UITableViewController的最简单的方法是什么？

What is the simplest way to add UIToolBar to UITableViewController? I'm depending on edit functionality, so I can't change UITableViewController to UIViewController easily.

推荐答案

根本没有问题，

为了使其工作，您必须：

In order for this to work you must:

• 请确保您使用 UINavigationController 包含所有需要工具栏的视图控制器。


• 设置需要工具栏的视图控制器的 toolbarsItems 属性。

• Make sure that you use a UINavigationController to contain all your view controllers that needs a toolbar.
• Set the toolbarsItems property of the view controller that wants a toolbar.

几乎和设置视图控制器的标题一样简单，并且应该以同样的方式。很可能通过覆盖 initWithNibName：bundle：初始化。例如：

This is almost as easy as as setting the view controller's title, and should be done the same way. Most probably by overriding the initWithNibName:bundle: initializer. As an example:

-(id)initWithNibName:(NSString*)name bundle:(NSBundle*)bundle;
{
  self = [super initWithNibName:name bundle:bundle];
  if (self) {
    self.title = @"My Title";
    NSArray* toolbarItems = [NSArray arrayWithObjects:
        [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd 
                                                      target:self
                                                      action:@selector(addStuff:)],
        [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch 
                                                      target:self
                                                      action:@selector(searchStuff:)],
        nil];
    [toolbarItems makeObjectsPerformSelector:@selector(release)];
    self.toolbarItems = toolbarItems;
    self.navigationController.toolbarHidden = NO;
  }
  return self;
}

您也可以使用 setToolbarItems：animated： code>而不是分配到 toolbarItems 属性，以动态方式添加和删除工具栏项。

You can also use setToolbarItems:animated: instead of assigning to the toolbarItems property, to add and remove toolbar items in an animated fashion on the fly.
