【Unity3D游戏开发】iOS9 ReplayKit录制视频 (三十)

Unity游戏需要视频分享，之前用过第三方的，现在听说苹果有了自带的ReplayKit，毕竟是游戏中录制视频，视频的大小，压缩带来的性能影响，抱着试试看的态度加入了下，性能感觉还可以，但是架不住苹果的Objective-C和swift啊

#游戏目标: 为游戏增加视频分享

#开发环境: Unity5.3.0f4

#技术点: ReplayKit，需要ios9.0以上

直接上代码吧

ReplayKitProxy.h

#import <UIKit/UIKit.h>#import <ReplayKit/ReplayKit.h>@interface ReplayKitProxy : NSObject<RPPreviewViewControllerDelegate, RPScreenRecorderDelegate>+ (ReplayKitProxy*) sharedInstance;// 是否支持录像功能(仅ios9以上支持)+ (BOOL)isSupportReplay;// 开始录制视频- (void)startRecording;// 停止录制视频- (void)stopRecording;// 删除已录制视频，必须在stopRecording之后调用(eg.离开视频分享界面)- (void)discardRecording;// 显示视频- (void)displayRecordingContent;@end

ReplayKitProxy.m

#import "ReplayKitProxy.h"@interface  ReplayKitProxy () <RPPreviewViewControllerDelegate, RPScreenRecorderDelegate>@property RPPreviewViewController* previewViewController;@end@implementation ReplayKitProxy+ (ReplayKitProxy *)sharedInstance{    static ReplayKitProxy* _instance = nil;    static dispatch_once_t onceToken;    dispatch_once(&onceToken, ^{        _instance = [[ReplayKitProxy alloc] init];    });    return _instance;}+ (BOOL)isSupportReplay{    NSString* version = [[UIDevice currentDevice] systemVersion];        BOOL _ios90orNewer = [version compare: @"9.0" options: NSNumericSearch] != NSOrderedAscending;        return _ios90orNewer;}// 开始录制视频- (void)startRecording{    RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;        if (recorder.available == FALSE) {        NSLog(@"Replaykit is not available");        return;    }        if (recorder.recording == TRUE) {        NSLog(@"Replaykit is recording");        return;    }        // 添加代理:防止有些设备录制出来黑屏    recorder.delegate = self;        [recorder startRecordingWithMicrophoneEnabled:YES handler:^(NSError * _Nullable error) {        if (error) {            NSLog(@"%@", error.localizedDescription);        }    }];}// 停止录制视频- (void)stopRecording{    RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;    if (recorder.recording == FALSE) {        return;    }        [recorder stopRecordingWithHandler:^(RPPreviewViewController * _Nullable previewViewController, NSError * _Nullable error) {        if (error) {            NSLog(@"%@", error.localizedDescription);            // [self ShowRecordAlert:error.localizedDescription];            return;        } else {            if (previewViewController != NULL) {                previewViewController.previewControllerDelegate = self;                self.previewViewController = previewViewController;            }        }    }];}// 删除已录制视频，必须在stopRecording之后调用// eg.离开视频分享界面- (void)discardRecording{    RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;    if (recorder.recording == TRUE) {        return;    }        [recorder discardRecordingWithHandler:^{        NSLog(@"discardRecording complete");        self.previewViewController = NULL;    }];}// 显示视频- (void)displayRecordingContent{    UIViewController* rootViewController = [UIApplication sharedApplication].keyWindow.rootViewController;    [rootViewController presentViewController:self.previewViewController animated:YES completion:^{        NSLog(@"DIsplay complete!");    }];}// MARK: delegate RPPreviewViewControllerDelegate- (void)previewControllerDidFinish:(RPPreviewViewController*)previewController{    if (previewController != NULL) {        [previewController dismissViewControllerAnimated:YES completion:^{                    }];    }}// MARK: RPScreenRecorderDelegate- (void)screenRecorder:(RPScreenRecorder *)screenRecorder didStopRecordingWithError:(NSError *)error previewViewController:(nullable RPPreviewViewController *)previewViewController{    // Display the error the user to alert them that the recording failed.//    showScreenRecordingAlert(error.localizedDescription)        /// Hold onto a reference of the `previewViewController` if not nil.    if (previewViewController != NULL) {        self.previewViewController = previewViewController;    }}@end

# 注意点: ReplayKit.framework必须ios9.0以上才支持，所以需要将framework的属性设置为Optional，否则在9.0以下手机上会报错
