我正在使用 GPUImage 过滤图像，我将 GPUImage 集成到我的项目中，它完美地集成了，现在我想将 GPUImage 的文件访问到我的代码中。我遇到了链接器错误。
当我在视图控制器中使用此代码时
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
GPUImageFilter *selectedFilter;
switch (buttonIndex) {
case 0:
selectedFilter = [[GPUImageGrayscaleFilter alloc] init];
break;
case 1:
selectedFilter = [[GPUImageSepiaFilter alloc] init];
break;
case 2:
selectedFilter = [[GPUImageSketchFilter alloc] init];
break;
case 3:
selectedFilter = [[GPUImagePixellateFilter alloc] init];
break;
case 4:
selectedFilter = [[GPUImageColorInvertFilter alloc] init];
break;
case 5:
selectedFilter = [[GPUImageToonFilter alloc] init];
break;
case 6:
selectedFilter = [[GPUImagePinchDistortionFilter alloc] init];
break;
case 7:
selectedFilter = [[GPUImageFilter alloc] init];
break;
default:
break;
}
UIImage *filteredImage = [selectedFilter imageByFilteringImage:self.imgViewPhoto.image];
[self.imgViewPhoto setImage:filteredImage];
}
如何解决这个问题？等待答案..
