你的demo如果录制视频点击几次屏幕后会崩溃，reason: '*** -[AVAssetWriter finishWritingWithCompletionHandler:] Cannot call method when status is 2'

[xinyu1105]

• (void)stopWritingWithError:(NSError **)error {

self.isWriting = NO;

dispatch_async(self.dispatchQueue, ^{

[self.assetWriter finishWritingWithCompletionHandler:^{
	
	if (self.assetWriter.status == AVAssetWriterStatusCompleted) {
		
		dispatch_async(dispatch_get_main_queue(), ^{
			if ([self.delegate respondsToSelector:@selector(videoWriter:didOutputVideoAtPath:)]) {
				[self.delegate videoWriter:self didOutputVideoAtPath:self.assetWriter.outputURL];
			}
		});
		
	} else {
		
		*error = self.assetWriter.error;
		
	}
    self.assetWriter = nil;
}];

});
}

这个怎么解决呢?麻烦回复下,谢谢!!
