无法使用在内部使用.xib文件的iOS框架 [英] Unable to use iOS framework which is internally using .xib file

问题描述

我想通过以下网址中指定的步骤为iOS制作通用框架： Universal -framework-iOS

我有一个viewController类，该框架内部加载一个.xib文件。

下面是代码的一部分，显示了如何初始化viewController并显示相关视图：

  *** SomeViewController类的一部分实现，这是框架之外的*** / 
 
  - （void）viewDidLoad 
 {super bd 
 [super viewDidLoad]; 
 //在加载视图之后执行任何其他设置，通常来自nib。 
 
 self.viewControllerWithinFramework = [[ViewControllerWithinFramework alloc] initWithTitle：@我的自定义视图]; 
} 
  - （IBAction）showSomeView：（id）sender {
 [self.viewControllerWithinFramework showRelatedView]; 
} 
 
 / ***部分实现ViewControllerWithinFramework类，这是框架内部*** / 
 
  - （id）initWithTitle：（NSString * ）aTitle 
 {
 self = [super initWithNibName：@ViewControllerWithinFrameworkbundle：nil]; // ViewControllerWithinFramework.xib在框架内
 
 if（self）
 {
 _viewControllerTitle = aTitle; 
} 
 
 return self; 
} 
  

创建框架时，我包括所有.xib文件，包括ViewControllerWithinFramework.xib在其复制捆绑资源构建阶段。

现在我的问题是当我尝试集成该框架在其他项目，它崩溃与以下堆栈跟踪：

 示例[3616：a0b] ***由于未捕获异常终止应用程序'NSInternalInconsistencyException' ，原因：'Could not load NIB in bundle：'NSBundle< / Users / miraaj / Library / Application Support / iPhone Simulator / 7.0 / Applications / 78CB9BC5-0FCE-40FC-8BCB-721EBA031296 / Sample.app> （

解决方案

如果你使用通用框架 - iOS所有资源（包括Nib和图像）将被复制到一个单独的包（文件夹），如 MyApp.app/Myframework.bundle/MyNib.nib 。

您需要通过传递 NSBundle 对象而不是 nil 。你可以如下获得你的包对象：

  NSString * path = [[NSBundle mainBundle] pathForResource：@MyframeworkofType： @束]; 
 NSBundle * resourcesBundle = [NSBundle bundleWithPath：path]; 
  

至于图片，您可以在之前加上 Myframework.bundle / 到他们的名字：

  [UIImage imageNamed：@Myframework.bundle / MyImage
  
 
 
 
这也适用于Interface Builder。
 
 
 
更新框架是一个痛苦，特别是资源，所以更好地尝试使用 CocoaPods 。
 
I am trying to make a universal framework, for iOS by following steps specified in this URL: Universal-framework-iOS

I have a viewController class within, that framework which internally loads a .xib file.

Below is a part of code which shows, how I am initializing that viewController and showing related view:
/*** Part of implementation of SomeViewController class, which is outside the framework ***/

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.viewControllerWithinFramework = [[ViewControllerWithinFramework alloc] initWithTitle:@"My custom view"];
}
- (IBAction)showSomeView:(id)sender {
    [self.viewControllerWithinFramework showRelatedView];
} 

/*** Part of implementation of ViewControllerWithinFramework class, which is inside the framework ***/

- (id)initWithTitle:(NSString *)aTitle
{
   self = [super initWithNibName:@"ViewControllerWithinFramework" bundle:nil]; // ViewControllerWithinFramework.xib is within the framework

   if (self)
   {
       _viewControllerTitle = aTitle;
   }

   return self;
}
While creating the framework, I included all .xib files, including ViewControllerWithinFramework.xib within its Copy Bundle Resources build phase.

Now my problem is when I try to integrate that framework within other project, it crashes with below stack trace:
Sample[3616:a0b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/miraaj/Library/Application Support/iPhone Simulator/7.0/Applications/78CB9BC5-0FCE-40FC-8BCB-721EBA031296/Sample.app> (loaded)' with name 'ViewControllerWithinFramework''

    7   UIKit                               0x0033fc44 -[UIViewController view] + 35
Any ideas, how could I resolve this problem?

Note: It works fine if there is no any xib within the framework.
解决方案
If you're using Universal-framework-iOS all resources (including Nibs and images), will be copied inside a separate bundle (folder) such as MyApp.app/Myframework.bundle/MyNib.nib.

You need to specify this bundle by passing a NSBundle object instead of nil. Your can get your bundle object as follows:
NSString *path = [[NSBundle mainBundle] pathForResource:@"Myframework" ofType:@"bundle"];
NSBundle *resourcesBundle = [NSBundle bundleWithPath:path];
As for images you can just prepend Myframework.bundle/ to their names:
[UIImage imageNamed:@"Myframework.bundle/MyImage"
This also works in Interface Builder.

Finally your users to install/update a framework is a pain, specially with resources, so better try to use CocoaPods.
