Delete specified file from document directory

Question

I want to delete an image from my app document directory. Code I have written to delete image is:

 -(void)removeImage:(NSString *)fileName
{
    fileManag         


        

Answer 1

Swift 3.0:

func removeImage(itemName:String, fileExtension: String) {
  let fileManager = FileManager.default
  let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
  let nsUserDomainMask = FileManager.SearchPathDomainMask.userDomainMask
  let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
  guard let dirPath = paths.first else {
      return
  }  
  let filePath = "\(dirPath)/\(itemName).\(fileExtension)"
  do {
    try fileManager.removeItem(atPath: filePath)
  } catch let error as NSError {
    print(error.debugDescription)
  }}

Thanks to @Anil Varghese, I wrote very similiar code in swift 2.0:

static func removeImage(itemName:String, fileExtension: String) {
  let fileManager = NSFileManager.defaultManager()
  let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory
  let nsUserDomainMask = NSSearchPathDomainMask.UserDomainMask
  let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
  guard let dirPath = paths.first else {
    return
  }
  let filePath = "\(dirPath)/\(itemName).\(fileExtension)"
  do {
    try fileManager.removeItemAtPath(filePath)
  } catch let error as NSError {
    print(error.debugDescription)
  }
}
