Question

我想在popover中显示视图的子视图。详细说明，

我有一个mainViewController。我在这个mainViewController中有一个子视图'songListView'。我在mainViewController中有一个名为'list'的按钮。我想在点击“列表”按钮时在popover中显示songListView。

那么，我该怎么做呢。

Answer 1

您可以使用以下代码作为从UIButton

显示PopOver的参考

-(void) buttonAction:(id)sender {
   //build our custom popover view
   UIViewController* popoverContent = [[UIViewController alloc]
                  init];
   UIView* popoverView = [[UIView alloc]
                  initWithFrame:CGRectMake(0, 0, 200, 300)];
   popoverView.backgroundColor = [UIColor greenColor];
   popoverContent.view = popoverView;

   //resize the popover view shown
   //in the current view to the view's size
   popoverContent.contentSizeForViewInPopover =
                  CGSizeMake(200, 300);

   //create a popover controller
   self.popoverController = [[UIPopoverController alloc]
               initWithContentViewController:popoverContent];

   //present the popover view non-modal with a
   //refrence to the button pressed within the current view
   [self.popoverController presentPopoverFromRect:popoverButton.frame
               inView:self.view
               permittedArrowDirections:UIPopoverArrowDirectionAny
               animated:YES];

   //release the popover content
   [popoverView release];
   [popoverContent release];
}

Answer 2

我的问题解决了。我刚刚创建了另一个View Controller类，即'TempPopoverView'。

然后我将此TempPopoverView的视图设置为等于我的MainView的子视图

以下是我的代码中的代码段：

TempPopoverView *viewController = [[TempPopoverView alloc]initWithNibName:@"TempPopoverView" bundle:nil];

[self. songListView setHidden:NO];//songListView is subview of MainView
 viewController.view=self. songListView;
 UINavigationController *navCont = [[UINavigationController alloc]initWithRootViewController:viewController];
 navCont.navigationBar.tintColor = [UIColor colorWithRed:.102 green:.102 blue:.102 alpha:1];

[self showPopOverController:navCont andFrame:sender.frame andInView:self.view];//self.view is the MainView
[viewController release];
 [navCont release];

Answer 3

你可以在主视图上使用presentModalViewController。

例如

SongListView *songList = [[SongListView alloc] init];
[self presentModalViewController: songList animated: YES];

也有不同的动画。

Answer 4

就像你想在self.view中添加子视图一样简单

[popoverController.contentViewController.view addSubview:yourselfobject];

将子视图显示为弹出窗口时出现问题
