iOS-视频录制库、

既然有了播放在线视频, 那么我们也把录制加进来吧。

GitHub Page

首先初始化我们的视频录制器, 并添加到View

    self.captureManager = [[AVCaptureManager alloc] initWithPreviewView:self.view];
    self.captureManager.delegate = self;

设置代理并写代理方法

#pragma mark - AVCaptureManagerDeleagte

- (void)didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL error:(NSError *)error {
    
    if (error) {
        NSLog(@"error:%@", error);
        return;
    }
    
    if (!isNeededToSave) {
        return;
    }
    
    [self saveRecordedFile:outputFileURL];
}

开始录制 结束录制

[self.captureManager startRecording];
[self.captureManager stopRecording];

保存录制后的视频 - 写到代理方法里的

- (void)saveRecordedFile:(NSURL *)recordedFile {
    
    [SVProgressHUD showWithStatus:@"Saving..."
                         maskType:SVProgressHUDMaskTypeGradient];
    
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
    dispatch_async(queue, ^{
        
        ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
        [assetLibrary writeVideoAtPathToSavedPhotosAlbum:recordedFile
                                         completionBlock:
         ^(NSURL *assetURL, NSError *error) {
             
             dispatch_async(dispatch_get_main_queue(), ^{
                 
                 [SVProgressHUD dismiss];
                 
                 NSString *title;
                 NSString *message;
                 
                 if (error != nil) {
                     
                     title = @"Failed to save video";
                     message = [error localizedDescription];
                 }
                 else {
                     title = @"Saved!";
                     message = nil;
                 }
                 
                 UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                                 message:message
                                                                delegate:nil
                                                       cancelButtonTitle:@"OK"
                                                       otherButtonTitles:nil];
                 [alert show];
             });
         }];
    });
}

.h文件

@property (nonatomic, assign) id<AVCaptureManagerDelegate> delegate;
@property (nonatomic, readonly) BOOL isRecording;

- (id)initWithPreviewView:(UIView *)previewView;
- (void)toggleContentsGravity;
- (void)resetFormat;
- (void)switchFormatWithDesiredFPS:(CGFloat)desiredFPS;
- (void)startRecording;
