   //Blur the UIImage with a CIFilter
    CIImage *imageToBlur = [CIImage       imageWithCGImage:viewImage.CGImage];
    CIFilter *gaussianBlurFilter = [CIFilter filterWithName: @"CIGaussianBlur"];
    [gaussianBlurFilter setValue:imageToBlur forKey: @"inputImage"];
    [gaussianBlurFilter setValue:[NSNumber numberWithFloat: 10] forKey: @"inputRadius"];
    CIImage *resultImage = [gaussianBlurFilter valueForKey: @"outputImage"];
    UIImage *endImage = [[UIImage alloc] initWithCIImage:resultImage];
    //Place the UIImage in a UIImageView
    UIImageView *newView = [[UIImageView alloc] initWithFrame:self.bounds];
    newView.image = endImage;
    [self addSubview:newView];

推荐答案

使用 Gaussian Blur 创建UIImage并将图像添加到此textField或Button(无论您拥有什么).

Create an UIImage with Gaussian Blur and add image onto this textField or Button (whatever you have).
