-[GPUImageFilter initWithVertexShaderFromString:] 断言失败

Question

出现如下错误

*** Assertion failure in -[GPUImageFilter initWithVertexShaderFromString:fragmentShaderFromString:], /Users/XYZ/Downloads/GPUImage-master/framework/Source/GPUImageFilter.m:94

在设置框架路径后，我已经按照 https://github.com/BradLarson/GPUImage 中的说明进行了设置，所有其他内容编写了以下代码进行测试，但出现了上述错误。

GPUImageVideoCamera *videoCamera = [[GPUImageVideoCamera alloc] initWithSessionPreset:AVCaptureSessionPreset640x480 cameraPosition:AVCaptureDevicePositionBack];
videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait;

GPUImageFilter *customFilter = [[GPUImageFilter alloc] initWithFragmentShaderFromFile:@"CustomShader"];
GPUImageView *filteredVideoView = [[GPUImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, viewWidth, viewHeight)];

// Add the view somewhere so it's visible

[videoCamera addTarget:customFilter];
[customFilter addTarget:filteredVideoView];

[videoCamera startCameraCapture];

请帮我解决这个问题...

Answer 1

NSAssert(NO, @"Filter shader link failed");

你的link"CustomShader"是错误的。你的项目中有CustomShader.fsh吗？
