Question

我正在尝试将我选择的图像转换为base64然后上传到服务器但是当我进入图像选择器时我似乎得到一个奇怪的错误我得到错误创建一个未知类型的图像格式是一个错误

def PinGuess(pin,nums):
  global Found,Invalid
  while not Found:
    Numbers = xrange(nums)
    current_pin = int(choice(Numbers))
    if current_pin not in Invalid:
     call(['clear'])
     print 'Trying: {}'.format(current_pin)
     if current_pin == pin: Found = True
     else: Invalid.append(current_pin)


  print len(Invalid)

if __name__ == '__main__':
  Found = False
  Invalid = []
  Pin = 123

  for i in range(1):
   Process(target=PinGuess, args=(Pin,300)).start()

Answer 1

您是否尝试在选择器委托功能中将AnyObject更改为Any？ swift3的正确语法是：

func imagePickerController(_ picker: UIImagePickerController,
                               didFinishPickingMediaWithInfo info: [String : Any]) {
}

Answer 2

试试这个：

    if let chosenImage =  info[UIImagePickerControllerOriginalImage] as? UIImage {
        ...
    }

Answer 3

我在选择器中点击图像时在模拟器中收到错误，但是在用户通过点击“选择”按钮确认选择之前。也就是说，该应用程序在所有外观上都可以正常工作。

由于用户也可以点击“取消”但保留在选择器中（因此在控制返回应用程序之前，点击另一个图像会在控制台上出现相同的错误），我怀疑问题出在Apple的代码中（至少在模拟器中运行时。）
