我正在尝试使用ReplayKit
将记录功能添加到基于C++的游戏中。我检查游戏代码中的iOS版本是否为9.0或更高版本,如果是,则将调用RecordReplayIOS::startRecording()
,然后ReplayKit应该开始记录。
出于某种原因,startRecordingWithMicrophoneEnabled
函数始终返回错误-5803
,根据API文档,这就是RPRecordingErrorFailedToStart
。有什么想法我做错了吗?RecordReplayIOS.hpp
:
#ifndef __RECORD_REPLAY_IOS_HPP__
#define __RECORD_REPLAY_IOS_HPP__
class RecordReplayIOS {
public:
static bool canRecord();
static void startRecording();
static void stopRecording();
};
#endif
RecordReplayIOS.mm
:#include "RecordReplay_ios.hpp"
#include "ReplayKit/ReplayKit.h"
@interface Recorder : NSObject
+(void)startRecording;
+(void)stopRecording;
@end
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
bool RecordReplayIOS::canRecord() {
// ReplayKit needs at least iOS 9
if (SYSTEM_VERSION_LESS_THAN(@"9.0")) {
return false;
}
return true;
}
void RecordReplayIOS::startRecording() {
[Recorder startRecording];
}
void RecordReplayIOS::stopRecording() {
[Recorder stopRecording];
}
@implementation Recorder
+(void)startRecording {
RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;
recorder.delegate = self;
[recorder startRecordingWithMicrophoneEnabled:false handler:^(NSError * error) {
if(error != nil) {
NSString* desc = error.description;
return;
}
}];
}
+(void)stopRecording {
RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;
[recorder stopRecordingWithHandler:^(RPPreviewViewController *previewViewController, NSError *error) {
if(error != nil) {
NSString* desc = error.description;
return;
}
if(previewViewController) {
//do stuff...
}
}];
}
@end
最佳答案
代码没有错。看来我只是尝试将ReplayKit与太旧的iPad一起使用。显然ReplayKit需要A7或A8处理器。我的具有A6处理器的iPad 4根本无法与ReplayKit一起使用。
检查设备是否可以使用ReplayKit的正确方法是查询RPScreenRecorder.sharedRecorder.available
。如果设备支持ReplayKit,则返回true。
