在这个方法(```LBXZXCapture.m ``` ```- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection```)里面加一句 ```oc [NSThread sleepForTimeInterval:0.5]; ``` 我感觉是运算密集,计算图像中包含的二维码条形码, 实际情况不需要那么快, 让线程休息0.5秒,测试cpu降低到20 - 40 %. #123 #83
