ios - ReplayKit 在我的 Objective-C 代码中不起作用

Question

有谁知道如何在 Objective-C 中使用 ReplayKit？

要在我的代码中使用 ReplayKit，我按照 api 实现 RPScreenRecoderDelegate , RPPreviewViewControllerDelegate在我的appDelegate .

#import <ReplayKit/ReplayKit.h>

@interface AppDelegate : NSObject <UIApplicationDelegate,
                                    NSURLConnectionDelegate,
                                    UIAlertViewDelegate,
                                    MFMailComposeViewControllerDelegate,
                                    RPPreviewViewControllerDelegate,
                                    RPScreenRecorderDelegate>
{}

然后在我的游戏 View 中，单击“录制”按钮以触发录制，如下所示:

- (void)StartRecording
{
    RPScreenRecorder* recorder =  RPScreenRecorder.sharedRecorder;
    recorder.delegate = self;
    [recorder startRecordingWithMicrophoneEnabled:YES handler:^(NSError *error) {

        if(error)
        {
            [self ShowRecordAlert:error.localizedDescription];
        }
    }];
}

使用“stop_btn”停止录制屏幕:

- (void)StopRecording
{
    RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;

    [recorder stopRecordingWithHandler:^(RPPreviewViewController * previewViewController, 
NSError * error) {

        if(error)
        {
            [self ShowRecordAlert:error.localizedDescription];
        }

        if(previewViewController)
        {
            previewViewController.previewControllerDelegate = self;

            TiIOSDevice* device = (TiIOSDevice*)Game::Get()->GetDevice();
            UIViewController* con = (UIViewController*)device->GetViewController();

            previewViewController.modalPresentationStyle = UIModalPresentationFullScreen;

            [con presentViewController:previewViewController animated:YES completion:nil];
        }

    }];
}


//Implements two callbacks to capture the error:

- (void)screenRecorder:(RPScreenRecorder *)screenRecorder
            didStopRecordingWithError:(NSError *)error
            previewViewController:(RPPreviewViewController *)previewViewController
{
    if(error)
    {
        [self ShowRecordAlert:error.localizedDescription];
    }
}

- (void)previewControllerDidFinish:(RPPreviewViewController *)previewController
{
    [previewController dismissViewControllerAnimated:YES completion:nil];
}

但是，当我触摸 '"Record"或 "Stop_btn"` 时，没有进入相应的处理程序。

我打印 sharedRecorder.recording值和 sharedRecorder.microphoneEnable值，它们都返回 false。

不知道是哪一步丢失了，请给我一些建议。

要回答 Veslam 的问题，您可以这样做。假设您有自己的带有窗口属性的 AppDelegate:

@interface MyAppDelegate : NSObject <UIApplicationDelegate> 
{

}

@property (nonatomic, retain) UIWindow* myWindow;

在 MyAppDelegate.mm 文件中，您将像以前一样初始化 myWindow，可能在 didFinishLaunchingWithOptions 中。然后您必须为 AppDelegate 的 window 属性定义 setter，如下所示:

-(UIWindow*) window
{
  // this is necessary so that ReplayKit can display its popup window
  return myWindow;
}

这将在您尝试开始录制时修复“AppDelegate UIWindow:unrecognized selector to instance”错误。
