我想在UIPopoverController上添加两个按钮，如下面的屏幕截图所示： HTML Edit

感谢您的帮助！

Answer 1

将视图控制器添加到UINavigationController，然后将导航控制器添加到UIPopoverController。然后在你的UIViewController的viewDidLoad方法中，将此代码放在：

中

UIBarButtonItem *okButton = [[UIBarButtonItem alloc] initWithTitle:@"Ok" style:UIBarButtonItemStyleBordered target:self action:@selector(okayButtonPressed)];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelButtonPressed)];

self.navigationItem.title = @"My Title";

[self.navigationItem setLeftBarButtonItem:cancelButton animated:NO];
[self.navigationItem setRightBarButtonItem:okButton animated:NO];

[cancelButton release];
[okButton release];

Answer 2

您需要直接使用UINavigationController初始化popover。然后将根视图设置为自定义视图控制器。

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:yourViewController];     
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:navigationController];

Answer 3

使用UINavigationController作为弹出窗口。然后，访问导航控制器的.navigationBar property，获取.topItem，并设置其.leftBarButtonItem和.rightBarButtonItem。

Answer 4

我不会像之前的海报建议那样使用导航控制器，苹果建议不要在ipad上使用导航控制器（有充分的理由）它不像你期望的那样在弹出时将VC推入堆栈时使用，现在你真的不想使用它的“导航”方面，但我不会使用导航控制器只是因为你蚂蚁吧....改为使用UIToolBar，并将其按钮设置为你想要的任何东西......这里不需要使用导航控制器......

当我这样做时，我的navBar似乎不适合UIPopoverController，如下所示：

这就是我正在做的事情：

// alloc the Direct Reports view controller.
ToolsViewController *toolsViewController = [[[ToolsViewController alloc] init] autorelease];

UINavigationController *toolsNavController = [[[UINavigationController alloc] initWithRootViewController:toolsViewController] autorelease];
toolsNavController.title = @"Tools";
toolsNavController.view.frame = CGRectMake(0.0, -10.0, 320.0, POPOVER_HEIGHT);

if(![self.toolsPopoverController isPopoverVisible]){
    // show popover

    self.toolsPopoverController = [[[UIPopoverController alloc] initWithContentViewController:toolsNavController] autorelease];
    self.toolsPopoverController.delegate = self;
    self.toolsPopoverController.popoverContentSize = CGSizeMake(320.0, POPOVER_HEIGHT);
    [self.toolsPopoverController presentPopoverFromBarButtonItem:sender 
                                     permittedArrowDirections:UIPopoverArrowDirectionAny 
                                                     animated:YES];

} else {
    // close popover
    [self.toolsPopoverController dismissPopoverAnimated:YES];
}

这很有用！

//Determine how to present this view based on device
if ([UIDevice currentDevice ].userInterfaceIdiom == UIUserInterfaceIdiomPad) {
    BNRAssetTypeViewController *contentViewController = [[BNRAssetTypeViewController alloc] init];
    UINavigationController *popOverNavigation = [[UINavigationController alloc] initWithRootViewController:contentViewController];

    self.assetPickerPopover = [[UIPopoverController alloc] initWithContentViewController:popOverNavigation];

    [self.assetPickerPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

}

然后在contentViewController的init函数中添加此

//add a barbutton item which will help in adding new type

UIBarButtonItem *bbi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addNew:)];

//set bar item to right side of navbarite
self.navigationItem.rightBarButtonItem =bbi ;

UIPopoverController顶部的按钮
