Question

我有一个由storyboard创建的项目，在项目中连接和移动每个viewcontroller的方法是通过导航栏（后面的底部）。我想在我的项目中应用由xib编写的metaio sdk。 sdk工作得很好，但问题是xib不包含导航栏。该应用无法返回上一页。我试图将xib转换成故事板，但没有成功。

我有ARViewController.h / m / xib

#import <UIKit/UIKit.h>
#import <metaioSDK/MetaioCloudPlugin/MetaioCloudPluginViewController.h>

@interface ARViewController : MetaioCloudPluginViewController
{
bool    m_useLocationAtStartup; //!< Flag to indicate if we should use the location at startup
}

- (IBAction)onBtnClosePushed:(id)sender;

@end

的.m

#import "ARViewController.h"
#import "ASImageSharingViewController.h"

@implementation ARViewController

#pragma mark - View lifecycle


- (void) viewDidLoad
{
[super viewDidLoad];

// use this call to move the radar position
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
    [self setRadarOffset:CGPointMake(-16, -20) scale:0.825f anchor:ANCHOR_TR];
}
else
{
    [self setRadarOffset:CGPointMake(-4.5, -20) scale:0.55f anchor:ANCHOR_TR];
}


// add the popup view to the view hierarchy if it is not present there already.
if( ![self.objectContextView  superview] )
{
    // we add it to the screen
    [self.view addSubview:self.objectContextView];

    [self.objectContextView setHidden:YES];
}
}

我将xib转移到故事板的方法是： 1.创建空的unviewcontroller并删除默认视图。 2.将视图从ARViewController.xib复制到新的unviewcontroller 3.将ARViewController设置为新的unviewcontroller

中的自定义类

但是，当我运行项目时，它仍然在xib文件中运行，而不是在storyboard中运行unviewcontroller。

我的问题是：

在此视图中拥有导航栏的最简单方法是什么？将xib转换为storyboard或将导航栏直接转换为xib？
如何将此xib转换为故事板，以便导航栏可以在此页面中使用？
如何将带有背底的导航栏放到xib上？（我正在使用Xcode 5）

Answer 1

你应该使用UINavigationController这是你所有问题的答案。

如何通过导航栏在同一个项目中连接xib和storyboard？
