GPUImage相机..white屏幕

Question

我有一个iPad 2，其中我在我viewDidLoad中IAM调用此

-(void)stillCameraStart{ 
GPUImageStillCamera *stillCam=[[GPUImageStillCamera alloc]init]; 
GPUImageView *filterView = [[GPUImageView alloc] initWithFrame:CGRectMake(0.0, 0.0,768, 1024)]; 
GPUImageGammaFilter *filter = [[GPUImageGammaFilter alloc] init]; 

[stillCam addTarget: filter]; 
[filter addTarget: filterView]; 
[stillCam startCameraCapture]; 
} 

但所有我得到的是白色screen.am我做错了测试代码？我期待一台相机开始

Answer 1

你错过了这个说法？

[self.view addSubview:filterView];
