我使用以下代码进行曝光调整及其工作。我需要用于锐化，去噪，高光，色温，阴影，模糊等的滤镜名称。
[CIFilter filterWithName: @"CIExposureAdjust"
keysAndValues: @"inputImage", [_imageView image], nil];

我写信给您之前发布的所有过滤器的帖子链接。我会重复：link to all filters。
例如，你需要模糊效果。模糊是类别，有7个过滤器：
等等。
答案 1 :(得分：17)
您需要做的就是询问CIFilter过滤器名称。然后，您可以向每个过滤器询问其attributes，它会返回一个字典，用于描述过滤器接受的每个输入和输出参数。
NSArray* filters = [CIFilter filterNamesInCategories:nil];
for (NSString* filterName in filters)
{
NSLog(@"Filter: %@", filterName);
NSLog(@"Parameters: %@", [[CIFilter filterWithName:filterName] attributes]);
}
例如，这是CIZoomBlur过滤器的上述代码的输出：
Filter: CIZoomBlur
Parameters: {
CIAttributeDescription = "Simulates the effect of zooming the camera while capturing the image.";
CIAttributeFilterCategories = (
CICategoryBlur,
CICategoryVideo,
CICategoryStillImage,
CICategoryBuiltIn
);
CIAttributeFilterDisplayName = "Zoom Blur";
CIAttributeFilterName = CIZoomBlur;
CIAttributeReferenceDocumentation = "http://developer.apple.com/cgi-bin/apple_ref.cgi?apple_ref=//apple_ref/doc/filter/ci/CIZoomBlur";
inputAmount = {
CIAttributeClass = NSNumber;
CIAttributeDefault = 20;
CIAttributeDescription = "The zoom-in amount. Larger values result in more zooming in.";
CIAttributeDisplayName = Amount;
CIAttributeIdentity = 0;
CIAttributeMin = 0;
CIAttributeSliderMax = 200;
CIAttributeSliderMin = 0;
CIAttributeType = CIAttributeTypeDistance;
CIUIParameterSet = CIUISetBasic;
};
inputCenter = {
CIAttributeClass = CIVector;
CIAttributeDefault = "[150 150]";
CIAttributeDescription = "The x and y position to use as the center of the effect.";
CIAttributeDisplayName = Center;
CIAttributeType = CIAttributeTypePosition;
CIUIParameterSet = CIUISetBasic;
};
inputImage = {
CIAttributeClass = CIImage;
CIAttributeDescription = "The image to use as an input image. For filters that also use a background image, this is the foreground image.";
CIAttributeDisplayName = Image;
CIUIParameterSet = CIUISetBasic;
};
outputImage = {
CIAttributeClass = CIImage;
};
}
但大多数情况下，您可能只使用the docs。

在Swift（撰写本文时为4.2）中，您可以使用此代码获取所有过滤器名称：
对于指定类别中的过滤器：
CIFilter.filterNames(inCategory: "Name_of_the_category")
对于指定类别中的过滤器：
CIFilter.filterNames(inCategories: ["Name_of_the_category_1", "Name_of_the_category_2"])
对于所有类别中的过滤器，只需在inCategory或inCategories中传递nil：
CIFilter.filterNames(inCategory: nil)
或
CIFilter.filterNames(inCategories: nil)
以上所有功能均返回Array值中的String过滤器名称：
[
"CIAccordionFoldTransition",
"CIAdditionCompositing",
"CIAffineClamp",
"CIAffineTile",
"CIAffineTransform",
"CIAreaAverage",
"CIAreaHistogram"...

必须承认它不容易阅读，但其答案与目标C上的第一个答案相当。
for filtername in filters {
print("filter \(filtername)")
print("attributes \(CIFilter.init(name: filtername)?.attributes.keys.description)")
}
产生这个...
filter CIAccordionFoldTransition
attributes Optional("[\"inputImage\", \"CIAttributeFilterDisplayName\", \"inputTargetImage\", \"CIAttributeFilterAvailable_iOS\", \"CIAttributeFilterAvailable_Mac\", \"inputNumberOfFolds\", \"inputFoldShadowAmount\", \"inputBottomHeight\", \"CIAttributeReferenceDocumentation\", \"inputTime\", \"CIAttributeFilterCategories\", \"CIAttributeFilterName\"]")
filter CIAdditionCompositing
attributes Optional("[\"CIAttributeFilterCategories\", \"CIAttributeFilterName\", \"CIAttributeFilterDisplayName\", \"inputImage\", \"CIAttributeReferenceDocumentation\", \"CIAttributeFilterAvailable_iOS\", \"CIAttributeFilterAvailable_Mac\", \"inputBackgroundImage\"]")
因此，这些长字符串中包含信息，您只需要选择它即可：）
