  • either I did not understand the question, or the answer cannot be done, after the image is loaded into the memory, the system itself does not know where the image came from - Max Mikheyenko
  • I have long suspected that all is not well in the Danish kingdom ... but these things can not be stuck =? func imagePickerController (picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String: AnyObject]) {... and just func pickerView (pickerView: UIPickerView !, didSelectRow row: Int, inComponent component: Int) ... because the system takes an array from an array, didn’t chooseRow row: Int, inComponent component: Int) because it is retrieved from an array by the array, byCeponEtRow row: Int, inComponent component: Int) because it is retrieved from an array by the array, it is taken from the array by the array, from Component Component Int: in, inComponent component: Int) because it is taken from the array by the array from the array, byCeponentRow row: Int, inComponent component: Int) ... ... I don’t have to have a file name - it’s enough by the numerical value ... for how long I’m trying to slip somehow, but nothing good came out ... @ Max Mikheyenko - user198638

Standardly this functionality is not provided. And if the image is displayed, the file name cannot be obtained, plus not the fact that the image is from a file, maybe it is downloaded from the network.

But you can create a variable and store in it the name of the file you take. You can create your own class inherited from a UIImage and specify the file name in the class field.

  • I tried the recipe = for some reason, it works the other way around. if the condition background [0] is not met - print ("imageBackground works_0") and if the condition is met i.e. The necessary value is loaded into the background of the screen - background [0] - print ("view.backGroundColor no result") = it happens =? and more on this advice - is there anything like an example or similar ... @ VAndkJ - user198638
