Yes..

Add a new method in ASScreenRecorder.h

- (BOOL)startRecordingWithView:(UIView*)view;

Add a new property in .m

@property (strong, nonatomic) UIView *recordingView;

Implement the new method:

- (BOOL)startRecordingWithView:(UIView*)view
{
    self.recordingView = view;

    if (!_isRecording) {
        [self setUpWriter];
        _isRecording = (_videoWriter.status == AVAssetWriterStatusWriting);
        _displayLink = [CADisplayLink displayLinkWithTarget:self selector:@selector(writeVideoFrame)];
        [_displayLink addToRunLoop:[NSRunLoop mainRunLoop] forMode:NSRunLoopCommonModes];
    }
    return _isRecording;
}

In - (void)writeVideoFrame (line 240) change:

dispatch_sync(dispatch_get_main_queue(), ^{
            UIGraphicsPushContext(bitmapContext); {

                if (self.recordingView)
                {
                    [self.recordingView drawViewHierarchyInRect:CGRectMake(0, 0, _viewSize.width, _viewSize.height) afterScreenUpdates:NO];
                }
                else
                {
                    for (UIWindow *window in [[UIApplication sharedApplication] windows]) {
                        [window drawViewHierarchyInRect:CGRectMake(0, 0, _viewSize.width, _viewSize.height) afterScreenUpdates:NO];
                    }
                }

            } UIGraphicsPopContext();
        });
