iOS系統(tǒng)錄屏-ReplayKit框架

ReplayKit框架說明

  • ReplayKit框架是蘋果提供的錄制視頻的框架.
  • 優(yōu)點(diǎn):錄制流暢不卡頓
  • 缺點(diǎn):
  • 不能定制預(yù)覽頁面
  • 如果再次錄制開始時(shí)間距離上次錄制完成時(shí)間超過8分鐘,還會(huì)彈框提示錄制權(quán)限
  • 默認(rèn)保存到相冊,不能指定保存路徑.
  • ReplayKit只支持ios9+,部分最新函數(shù)只支持10+

開始錄制

  • #import <ReplayKit/ReplayKit.h>
  • 添加代理 <RPScreenRecorderDelegate, RPPreviewViewControllerDelegate>
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSKeyValueChangeKey,id> *)change context:(void *)context
{
    if ([keyPath isEqualToString:@"recording"]) {
        NSLog(@"keyPath === %@",object);
        if ([change valueForKey:@"recording"] == 0) {
            NSLog(@"可以錄制");
        }else
        {
            NSLog(@"++++++++++++不可以");
        }
    }
}

//開始錄屏
- (void)startRecoding
{
    //將開啟錄屏功能的代碼放在主線程執(zhí)行
//    __weak typeof (self)weakSelf = self;
    dispatch_async(dispatch_get_main_queue(), ^{
        if ([[RPScreenRecorder sharedRecorder] isAvailable] && [self isSystemVersionOk]) { //判斷硬件和ios版本是否支持錄屏
            NSLog(@"支持ReplayKit錄制");
            //這是錄屏的類
            RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;
            recorder.delegate = self;
            
            //開起錄屏功能
            //9.0+函數(shù)(在10+版本被廢棄,替換為startRecordingWithHandler:)
            [recorder startRecordingWithMicrophoneEnabled:YES handler:^(NSError * _Nullable error) {

                if (error) {
                    IsDecoderScreen = 0;
                    NSLog(@"========%@",error.description);

                } else {

                    }
                }
            }];
            //10.0+函數(shù)
            //在此可以設(shè)置是否允許麥克風(fēng)（傳YES即是使用麥克風(fēng)，傳NO則不是用麥克風(fēng)）

結(jié)束錄制

//結(jié)束錄屏
- (void)stopRecording
{
    __weak typeof (self)weakSelf = self;
    [[RPScreenRecorder sharedRecorder] stopRecordingWithHandler:^(RPPreviewViewController *previewViewController, NSError *  error){

            [startRecordScreenBtn setTitle:@"錄屏" forState:UIControlStateNormal];
        } else {
            [_RPPreview setPreviewControllerDelegate:self];
            startRecordScreenBtn.backgroundColor = [UIColor greenColor];

            IsDecoderScreen = 0;
            //在結(jié)束錄屏?xí)r顯示預(yù)覽畫面
            [weakSelf showVideoPreviewController:_RPPreview withAnimation:YES];

    }];
}

預(yù)覽保存/取消

//顯示視頻預(yù)覽頁面,animation=是否要?jiǎng)赢嬶@示

    });
}

//關(guān)閉視頻預(yù)覽頁面，animation=是否要?jiǎng)赢嬶@示

    //UI需要放到主線程
    dispatch_async(dispatch_get_main_queue(), ^{

ReplayKit代理實(shí)現(xiàn)

其他補(bǔ)充方法

//顯示彈框提示
- (void)showAlert:(NSString *)title andMessage:(NSString *)message {

//判斷對應(yīng)系統(tǒng)版本是否支持ReplayKit
- (BOOL)isSystemVersionOk {
    if ([[UIDevice currentDevice].systemVersion floatValue] < 9.0) {
        return NO;
    } else {
        return YES;
    }

相冊轉(zhuǎn)移到沙盒并從沙盒上傳到服務(wù)器

  • 保存到相冊后就能把數(shù)據(jù)轉(zhuǎn)到沙盒,從而上傳到服務(wù)器了
  • (void)uploadVideoAsyn{}
  • 實(shí)現(xiàn)思路,參照我的另一篇文章:
