如何使用导航控制器创建静态子视图?

问题描述:

我已经创建了一个视图控制器堆栈的导航控制器。如何使用导航控制器创建静态子视图?

我想添加一个子视图在底部保持静态(不移动),而用户之间浏览这堆视图。

就像在某些应用程序中,底部有一个“广告栏”。

我该怎么做?

如果我理解正确的话,这是你想要的东西:

UIView below UINavigationController or below TabBar

您就可以向该通过创建包围UINavigationController的一个自定义的UIViewController。创建一个名为 “CustomViewController” 新品类,并粘贴以下代码:

接口

#import <UIKit/UIKit.h> 

@interface CustomViewController : UIViewController 

- (id)initWithViewController:(UIViewController*)viewController bottomView:(UIView*)bottomView; 

@end 

实现:

#import "CustomViewController.h" 

@implementation CustomViewController 

- (id)initWithViewController:(UIViewController*)viewController bottomView:(UIView*)bottomView 
{ 
    self = [super init]; 
    if (self) { 

     // Set up view size for navigationController; use full bounds minus 60pt at the bottom 
     CGRect navigationControllerFrame = self.view.bounds; 
     navigationControllerFrame.size.height -= 60; 
     viewController.view.frame = navigationControllerFrame; 

     // Set up view size for bottomView 
     CGRect bottomViewFrame = CGRectMake(0, self.view.bounds.size.height-60, self.view.bounds.size.width, 60); 
     bottomView.frame = bottomViewFrame; 

     // Enable autoresizing for both the navigationController and the bottomView 
     viewController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; 
     bottomView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; 

     // Add views as subviews to the current view 
     [self.view addSubview:viewController.view]; 
     [self.view addSubview:bottomView]; 
    } 
    return self; 
} 

@end 

现在使用CustomViewController:

UIView *myBottomView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 100)]; 
myBottomView.backgroundColor = [UIColor redColor]; 

CustomViewController *customViewController = [[CustomViewController alloc] initWithViewController:<yourNavigationController> bottomView:myView];

谢谢y欧!这正是我想要的 –

哦,,,我有问题,而实现它,我可以得到一个实施的源代码?这将如此伟大:D –

@PangHoMing如果你告诉我更多关于你如何设置你的UINavigationController的信息,我可以提供额外的代码/信息。 –

为什么不在与导航控制器视图相同的级别添加此静态子视图(通常是UIWindow附近的级别)。只需将它添加到最上面即可。
