无法分发 Mac Catalyst 扩展

Question

我成功上传到 Appstore iOS 一个带有多个扩展的应用程序，但是当我尝试为 Mac AppStore（一个 Mac Catalyst 应用程序）上传相同的应用程序时，我在两个扩展

上从 Xcode 得到以下错误

ERROR ITMS-90355: "Missing Info.plist value. No value for NSExtensionPrincipalClass found in extension Info.plist   
for MyApp.app/Contents/PlugIns/MyExtension.appex"

这些扩展是具有故事板文件的共享扩展和动作扩展，因此如果我在 Info.plist 文件中设置 NSExtensionPrincipalClass 键，我会在控制台中收到以下消息

Invalid Configuration: Either NSExtensionMainStoryboard or NSExtensionPrincipalClass   
must be specified in the extension's Info.plist file but not both.

当然没有出现扩展界面，也没有任何作用

有人知道如何解决这个问题吗？

或者，可以仅在 Info.plist 文件中设置 NSExtensionPrincipalClass 键，然后以编程方式调用故事板文件？

提前谢谢大家

Answer 1

在我的扩展中，我使用的是故事板，可以使用 NSExtensionPrincipalClass 而不是 NSExtensionMainStoryboard ？同时，我已经向 Apple 发送了反馈，

Answer 2

现在 Apple 已经解决了这个问题，我可以毫无问题地加载带有扩展的应用程序。

等待 Apple 的答复，我想出了一个解决方法，包括将故事板包装到新的 AUViewcontroller。

1.  include MyXib_Wrapper.h and MyXib_Wrapper.m
2.  Add to AudioUnitInterface.storyboard the ID mainStoryID
3.  Remove or comment the <AUAudioUnitFactory>  from your derived AUViewController class
4.  Update code in MyXib_Wrapper.m -> createAudioUnitWithComponentDescription according to your code (if you are performing more tasks)
5.  Replace in .plist NSExtensionMainStoryboard with NSExtensionPrincipalClass
6.  Sets MyXib_Wrapper for NSExtensionPrincipalClass and factoryFunction (very important!)

MyXib_Wrapper.h

#import <CoreAudioKit/AUViewController.h>
#import "AudioUnitViewController.h"

@class AudioUnitViewController;

@interface MyXib_Wrapper : AUViewController <AUAudioUnitFactory> {

    AudioUnitViewController *vc;
}
@end

MyXib_Wrapper.m

#import "MyXib_Wrapper.h"
#import "AudioUnitViewController.h"
#import "MyAudioUnit.h"

@implementation MyXib_Wrapper

- (MyAudioUnit *) createAudioUnitWithComponentDescription:(AudioComponentDescription) desc error:(NSError **)error {
    vc.audioUnit = [[MyAudioUnit alloc] initWithComponentDescription:desc error:error];

    // perform here more tasks    
    return vc.audioUnit;
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"AudioUnitInterface" bundle:nil];
        vc = (AudioUnitViewController*) [storyboard instantiateViewControllerWithIdentifier:@"mainStoryID"];
    }
    return self;
}

#pragma mark - View lifecycle
-(UIView*)view {
    return vc.view;
}

- (void)viewDidLoad {
    [super viewDidLoad];
    self.preferredContentSize = vc.preferredContentSize;
}
@end

从 Alessandro Petrolati 变通方法中获得灵感，我认为我找到了一个更简单的解决方案，至少在我的案例中，这两个扩展都运行良好。

1.  Replace in .plist NSExtensionMainStoryboard with NSExtensionPrincipalClass
2.  Update YourViewController.m file

将此 init 方法添加到您的 .m class 文件

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"YournStoryboardName" bundle:nil];
        self = (YourViewController*) [storyboard instantiateViewControllerWithIdentifier:@"YourStoryboardID"];
    }
    return self;
}

这似乎太简单了...

包验证成功，我终于顺利地将应用程序上传到 AppStore Connect！

我要做的就是在上线前查看最新详情...

试着相信！

我的方法是只使用一个简单的 VC 加载到代码中，然后 VC 包含实际呈现我们想要的 VC（从 Storyboard 加载）

info.plist 包含：

<key>NSExtension</key>
<dict>
    <key>NSExtensionPrincipalClass</key>
    <string>$(PRODUCT_MODULE_NAME).PreviewVCLoader</string>
    <key>NSExtensionAttributes</key>
    <dict>
        <key>QLSupportsSearchableItems</key>
        <true/>
        <key>QLSupportedContentTypes</key>
        <array>
            <string>com.hobbyistsoftware.jump</string>
        </array>
    </dict>
    <key>NSExtensionPointIdentifier</key>
    <string>com.apple.quicklook.preview</string>
</dict>

然后我的预览VC加载器class是

import UIKit
import QuickLook

class PreviewVCLoader: UIViewController, QLPreviewingController {

    
    init() {
        super.init(nibName: nil, bundle: nil)
    }

    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    
    lazy var realVC:PreviewViewController = {
        let board = UIStoryboard.init(name: "MainInterface", bundle: nil)
        guard let vc = board.instantiateViewController(withIdentifier: "PreviewViewController") as? PreviewViewController else {
            fatalError("Unable to instantiate storyboard in preview")
        }
        return vc
    }()
    
    override func viewDidLoad() {
         super.viewDidLoad()

        self.addChild(realVC)
        realVC.view.frame = self.view.bounds
        realVC.view.autoresizingMask = [.flexibleWidth,.flexibleHeight]
        self.view.addSubview(realVC.view)
        realVC.didMove(toParent: self)
    }
    
    func preparePreviewOfFile(at url: URL, completionHandler handler: @escaping (Error?) -> Void) {
        realVC.preparePreviewOfFile(at: url, completionHandler: handler)
    }
}
