Persist Array of Images Swift -

i want able save array, cardimages, contains uiimages via swiftyuserdefaults.

desired behavior

here exact desired behavior:

save array of uiimages nsuserdefaults via swiftyuserdefault library

retrieve images later

code stripped down little code

    var newphotokey = defaultskey<nsarray>("image")//setting swiftyuserdefaults persisted array          cardimages = [(uiimage(named: "myimagename.jpg")!)] //this array contains default value, , fill more         defaults[thekeyforstoringthisarray] = cardimages //this persisted array in array full of images should stored. error happens  var arraytoretreivewith = defaults[thekeyforstoringthisarray] as! [uiimage] //to retreive 

error

i following error:

attempt set non-property-list object ( ", {300, 300}" ) nsuserdefaults/cfpreferences value key image *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: 'attempt insert non-property list object ( ", {300, 300}" ) key image'

thanks!

the error message clear actually. uiimage not propertylist need change row data first. i'll put example below fyi saving big data images using nsuserdefaults not recommended. i'd use nsfilemanager , put in user documents directory. anyway

var newphotokey = defaultskey<nsarray>("image") cardimages = [(uiimage(named: "myimagename.jpg")!)]  var cardimagesrowdataarray: nsdata = [] image in cardimages {     let imagedata = uiimagejpegrepresentation(image, 1.0)     cardimagesrowdataarray.append(imagedata) } defaults[thekeyforstoringthisarray] = cardimagesrowdataarray   var arraytoretreivewith = defaults[thekeyforstoringthisarray] as! [nsdata] // here can use uiimage(data: data) 

if don't insist on using swiftyuserdefaults, can save in user documents directory, here how

func saveimage(image: uiimage){     if let imagedata = uiimagejpegrepresentation(image, 1.0) {          let manager = nsfilemanager()          if let docurl = manager.urlsfordirectory(.documentdirectory, indomains: .userdomainmask).first{              let uniquename = nsdate.timeintervalsincereferencedate()              let url = docurl.urlbyappendingpathcomponent("\(uniquename).jpg")              imagedata.writetourl(url, atomically: true)          }      }  }
