01-下载解压zip包
// 1.获取要下载文件的URL
guard let url = URL(string: "https://file.qf.56.com/f/style/static/gift/m/v2/zip/motianlun.zip") else {
return
}
// 2.获取下载的文件存放的路径
let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory, in: .userDomainMask)
// 3.开始进行下载
Alamofire.download(url, to: destination).response { (response : DefaultDownloadResponse) in
// 3.1.获取zip所在的目录
// URL : URL Scheme + Path
guard let zipPath = response.destinationURL?.path else {
return
}
print(zipPath) 这个是带有包名的路径
// 3.2.获取unzip存放的目录---删除最后的包名-解压的路径
let unzipPath = (zipPath as NSString).deletingLastPathComponent
// 3.3.解压文件
SSZipArchive.unzipFile(atPath: zipPath, toDestination: unzipPath)
}}
02.采集视频 采集音频 音视频的写入---代理中执行
03 GpuImage使用
// 1.获取到需要处理的图片
let image = imageView.image!
// 2.创建GPUImagePicture
let processImage = GPUImagePicture(image: image)
// 3.添加对应的滤镜
let blurFilter = GPUImageGaussianBlurFilter()
blurFilter.blurRadiusInPixels = 5
blurFilter.texelSpacingMultiplier = 10
// 4.将滤镜添加到processImage
processImage?.addTarget(blurFilter)
// 5.使用滤镜处理下一次显示的该图片
blurFilter.useNextFrameForImageCapture()
processImage?.processImage()
// 6.获取最新的图片
imageView.image = blurFilter.imageFromCurrentFramebuffer()
}
GpuImage添加其他滤镜
GPUImageStillCamera的使用
fileprivate var camera : GPUImageStillCamera!
fileprivate var filter : GPUImageBrightnessFilter!
var isFirst : Bool = true
@IBAction func startCapturing() {
if isFirst {
// 1.创建GPUImage中的相机 100 : 1
let camera = GPUImageStillCamera(sessionPreset: AVCaptureSessionPresetHigh, cameraPosition: .front)
camera?.outputImageOrientation = .portrait
self.camera = camera
// 2.添加滤镜
let filter = GPUImageBrightnessFilter()
camera?.addTarget(filter)
self.filter = filter
// 3.创建GPUImageView对象
let gpuImageView = GPUImageView(frame: view.bounds)
view.insertSubview(gpuImageView, at: 0)
filter.addTarget(gpuImageView)
isFirst = false
}
// 4.开始采集
camera?.startCapture()
}
@IBAction func stopCapturing() {
camera.stopCapture()
}
@IBAction func rotateCamera() {
camera.rotateCamera()
}
@IBAction func takePhoto() {
camera.capturePhotoAsImageProcessedUp(toFilter: filter) { (image : UIImage?, error : Error?) in
UIImageWriteToSavedPhotosAlbum(image!, nil, nil, nil)
}
}
