xcode - Setting Up an image in swift using NSuserdefaults -

i'm building swift game , need set images. code works string or integer:

for var = 0; < globalcurrentmembers.count; ++i {     var membersdefaultname = nsuserdefaults.standarduserdefaults()     membersdefaultname.setvalue(globalcurrentmembers[i].name, forkey: "globalcurrentmembersname\(i)")     membersdefaultname.synchronize() } 

but have error image

for var = 0; < globalcurrentmembers.count; ++i {     var membersdefaultimage = nsuserdefaults.standarduserdefaults()     membersdefaultimage.setvalue(globalcurrentmembers[i].image,                          forkey: "globalcurrentmembersimage\(i)")     membersdefaultimage.synchronize() } 

globalcurrentmembers array of member wich looks that:

class member {    var image = uiimage ()    var name = string ()    var progression = int()    var round = int()    var level = int()    var imageprogression = [uibutton]()      func init(){       image = uiimage(named: "default.png")!       name = "default"       progression = 0       round = 0       level = 0    } } 

so please can tell me how doing that.

uiimage not implement nscoding protocol, need convert uiimage nsdata first.

change code following:

  var imagedata = uiimagepngrepresentation(globalcurrentmembers[i].image)   var myencodedimagedata = nskeyedarchiver.archiveddatawithrootobject(imagedata)   membersdefaultimage.setobject(myencodedimagedata, forkey: "globalcurrentmembersimage\(i)") 

of course storing image nsuserdefaults not best practice, should store image in file directory.
