Question

I saved a picture to NSData with UserDefaults and now want it to be retrieved in a tableview cell.

Here is what I put in the ViewDidLoad of the TableView.m

NSData *imageData;
imageData = [NSKeyedArchiver archivedDataWithRootObject:yourUIImage];
[[NSUserDefaults standardUserDefaults] setObject:imageData forKey:@"image"];

And here is what I put in the TableView cellforRowatIndex

cell.imageView.image = [UIImage imageWithData:@"bild"];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

However when I start the programe I get an EXC_BAD_ACCESS Error at the cell.imageView.image line together with a “incompatible pointer types sending “NSString*” to paramater of type “NSData*””

Here is btw how I save the image in the first place:

if ([[NSUserDefaults standardUserDefaults] objectForKey:@"image"] == nil) { 
picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];

    NSData *imageData;
    UIImage *yourUIImage;
    imageData = [NSKeyedArchiver archivedDataWithRootObject:yourUIImage];
    [[NSUserDefaults standardUserDefaults] setObject:imageData forKey:@"image"];

Answer 1

Use NSKeyedUnarchiver as a counterpart to NSKeyedArchiver like this:

NSData *imageData = [[NSUserDefaults standardUserDefaults] dataForKey: @"image"];
cell.imageView.image = [NSKeyedUnarchiver unarchiveObjectWithData: imageData];
