初次尝试ios插件开发 & ReplayKit相关

昨天WonderParade把Ocean Adventure全部WFC了,然后想到录屏的时候,想起之前研究过的Quicktime录屏,在想能不能设备上录制

google之后搜到了ReplayKit,看起来非常简单的样子

最初尝试直接cycript执行,载入Framework之后虽然可以调用到开始和停止录制,但是因为cycript里的函数不是objc的方法,所以没办法搞回调

于是找了示例项目,粗略编了一个MS插件,作用仅仅就是声明一个ReplayKitObj类,代替调用开始/停止录制

毕竟也不熟练,怼了一阵搞出来一个能工作的版本,但是真正搞出来之后发现,ReplayKit录制质量特别渣……

基本上来讲,qt录制质量是100的话,airplay录制大概是85,rk就是60-70的样子…而且音频只录制了一个声道,这是最骚的

// Objective-C runtime hooking using CaptainHook:
//   1. declare class using CHDeclareClass()
//   2. load class using CHLoadClass() or CHLoadLateClass() in CHConstructor
//   3. hook method using CHOptimizedMethod()
//   4. register hook using CHHook() in CHConstructor

            UIViewController *rootController = [UIApplication sharedApplication].keyWindow.rootViewController;
            [rootController presentViewController:previewViewController animated:YES completion:nil];

}

+(void)previewControllerDidFinish:(RPPreviewViewController *)previewController {
    NSLog(@"previewControllerDidFinish");
    [[UIApplication sharedApplication].keyWindow.rootViewController dismissViewControllerAnimated:YES completion:nil];
}

+(void)previewController:(RPPreviewViewController *)previewController didFinishWithActivityTypes:(NSSet <NSString *>*)activityTypes {
	NSLog(@"activity - %@",activityTypes);
}

@end



总之,本来还在想要不要开发一个完整插件出来,但这么差的录制质量,还是算了
