Swift 3.0将图像写入目录
我有一个简单的ImagePicker供用户选择或拍摄个人资料照片。 我想将此image保存到Home Directory ，以便以后轻松加载。
问题是没有设置图像类型。
//Save Image _ = PPimagePicked.image let imageData = UIImageJPEGRepresentation(PPimagePicked.image!, 0.6) let compressedJPGImage = UIImage(data: imageData!) UIImageWriteToSavedPhotosAlbum(compressedJPGImage!, nil, nil, nil) // Get Document Root Path let path = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/profile.jpg") do { //Save image to Root try imageData?.write(to: path, options: .atomic) print("Saved To Root") } catch let error { print(error) }
确切的错误是：
“[Generic]创建具有未知类型的图像格式是一个错误”
请尝试此代码我在swift 2.2中使用它。 以下方法包括UIImageJPEGRepresentation，UIImagePNGRepresentation
if let image = UIImage(named: "example.png") { if let data = UIImageJPEGRepresentation(image, 0.8) { let filename = getDocumentsDirectory().appendingPathComponent("copy.png") try? data.write(to: filename) } } func getDocumentsDirectory() -> URL { let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask) let documentsDirectory = paths[0] return documentsDirectory } if let image = UIImage(named: "example.png") { if let data = UIImagePNGRepresentation(image) { let filename = getDocumentsDirectory().appendingPathComponent("copy.png") try? data.write(to: filename) } }
尝试将图像转换为图像数据
let imageCapture = UIImage(data: dataImage)! UIImageWriteToSavedPhotosAlbum((image: imageCapture), nil, nil, nil)
