如何将指定Swift代码转换为Objective-C？求可行转换方法

Got it, let's translate your Swift code to Objective-C while preserving all the original logic and best practices (like avoiding retain cycles with weak references). Here's the equivalent implementation:

NSString *token = @"0000000009";
[[SkyIdConfig sharedInstance] setupWithToken:token];

SkyDocumentsAnalyzer *skyIdView;

[[SkyIdConfig sharedInstance] loadAndConfigureWithCompletion:^(BOOL isConfigured, NSError * _Nullable error) {
    __weak typeof(self) weakSelf = self;
    if (error != nil || !isConfigured) {
        NSLog(@"%@", error.localizedDescription ?: @"Error !!!!");
        return;
    }
    
    dispatch_async(dispatch_get_main_queue(), ^{
        __strong typeof(weakSelf) strongSelf = weakSelf;
        if (!strongSelf) return;
        
        strongSelf->skyIdView = [[SkyIdBuilder sharedInstance] getDocumentAnalyzerInstanceWith:@"03" lang:@"fra"];
        if (strongSelf->skyIdView) {
            strongSelf->skyIdView.delegate = strongSelf;
            strongSelf->skyIdView.modalPresentationStyle = UIModalPresentationFullScreen;
            [strongSelf presentViewController:strongSelf->skyIdView animated:YES completion:nil];
        } else {
            NSLog(@"Error in config loading");
        }
    });
}];

Key Notes: #

• Singleton Access: Swift's SkyIdConfig.shared translates to [SkyIdConfig sharedInstance] in Objective-C (adjust if your SDK uses a different singleton method name like shared).
• Retain Cycle Prevention: We use __weak typeof(self) weakSelf and then __strong inside the main queue block to mirror Swift's [unowned self] behavior and avoid retain cycles.
• Method Naming: Swift's parameter labels are converted to Objective-C method segments (e.g., setup(With:) becomes setupWithToken: assuming the SDK's Objective-C interface follows standard conventions).
• Main Queue Dispatch: DispatchQueue.main.async becomes dispatch_async(dispatch_get_main_queue(), ^{...}) in Objective-C, ensuring UI updates run on the main thread.
• Optional Handling: Swift's optional checks translate to simple nil checks in Objective-C (if (strongSelf->skyIdView)).
