uiimageview - Swift: Remove All from the Subview -

i create multiple objects under same name , adding them subview (variables in german).

    wandx = (screenbreite - ((felderanzx - 0) * feldbreite))     wandy = ( screenhoehe - ((felderanzy - 5) * feldbreite))      for(var = 0; < 6; i++){         wand1 = uiimageview(frame: cgrectmake(wandx, wandy, feldbreite, feldbreite))         wand1.image = wand         self.addsubview(wand1)         wandxarray.insert(wandx, atindex: i)         wandyarray.insert(wandy, atindex: i)         wandx = wandx + feldbreite     } 

(creating row of walls)

but if want remove them wand1.removefromsuperview() removes last object added. possible solution found putting object on top , delete references. many object , many stages problem cpu usage.

edit: using method self.view.subviews.removeall()is getting me following error:

cannot use mutating member on immutable value: 'subviews' get-only property

wand1 = uiimageview(... rewriting reference on , over, never able remove last item created superview. either going have use array or dictionary:

class class {     var array = [uiimageview]();     ...     func something()     {     ...     for(var = 0; < 6; i++){     let wand1 = uiimageview();     wand1.image = wand     array.append(uiimageview(frame: cgrectmake(wandx, wandy, feldbreite, feldbreite)))     self.add.subview(wand1)//dunno how works code     wandxarray.insert(wandx, atindex: i)     wandyarray.insert(wandy, atindex: i)     wandx = wandx + feldbreite    }    ...    func removethisimage(index : int)    {        array[index].removefromsuperview();    } 

or can create object references every image create, each unique name

//no longer allowed if want remove subviews view , not concerned removing specifics, call self.subviews.removeall() self view contains subviews. //

looks have write own extension method handle this:

extension uiview {     func clearsubviews()     {         subview in self.subviews as! [uiview] {             subview.removefromsuperview();         }     } } 

then use it, self.view.clearsubviews();
