Nskeyedarchiver doesn't work on ios8 but works on ios7 and simulator
So, I use NSKeyedArchiver
for wishlist and it works fine on iOS 7 and on simulator, but not on iOS 8 devices.
Here is the code I'm using:
wishlist.m
- (void)viewDidLoad
{
NSString *voirexpo = @"viensdeexpo";
[[NSUserDefaults standardUserDefaults] setObject:voirexpo forKey:@"voirexpo"];
[[NSUserDefaults standardUserDefaults] synchronize];
[super viewDidLoad];
self.navigationController.navigationBar.barStyle = UIStatusBarStyleLightContent;
refait=0;
refait2=0;
wishlist * car2=[NSKeyedUnarchiver unarchiveObjectWithFile:@"myWishlist1.bin"];
NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
NSData * objectData = [defaults objectForKey:@"myWishlist1.bin"];
if(objectData != nil)
{
wishlist * car3 = [NSKeyedUnarchiver
unarchiveObjectWithData:objectData];
NSLog(@"YOOOOOOUUUUHOOOOO %@", [car3 description]);
}
NSLog(@"YOOOOOOUUUUHOOOOO %@", [car2 description]);
rent=@"0";
self.navigationItem.backBarButtonItem =
[[UIBarButtonItem alloc] initWithTitle:@"Back"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
}
-(NSString*)pathForCacheFile:(NSString*)fileName
{
NSArray*documentDir = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString*path = nil;
if (documentDir)
{
path = [documentDir objectAtIndex:0];
}
return [NSString stringWithFormat:@"%@/%@", path, fileName];
}
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if(_dataSource)
{
_dataSource=nil;
}
_dataSource=[NSKeyedUnarchiver unarchiveObjectWithFile:[self pathForCacheFile:@"myWishlist1.bin"]];
tableview.scrollEnabled=YES;
[tableview reloadData];
}
cardescription.m (view where I select a car to put in my wishlist)
-(NSString*)pathForCacheFile:(NSString*)fileName
{
NSArray* documentDir = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString* path = nil;
if (documentDir)
{
path = [documentDir objectAtIndex:0];
}
return [NSString stringWithFormat:@"%@/%@", path, fileName];
}
static wishlist *mywishlist;
-(void)saveInWishlist
{
if(mywishlist)
mywishlist=nil;
mywishlist=[wishlist new];
mywishlist.exponom=wishexpo;
mywishlist.idvoiture=TelephoneCellulaire;
mywishlist.imvoiture=dataimage;
mywishlist.objid=objectId;
{
NSMutableArray *temp=[NSKeyedUnarchiver unarchiveObjectWithFile:[self pathForCacheFile:@"myWishlist1.bin"]];
// mywishlist.imageSrc=filePath;
if(temp.count==0 || temp==nil)
{
NSMutableArray*newArr=[NSMutableArray array];
[newArr addObject:mywishlist];
[NSKeyedArchiver archiveRootObject:newArr toFile:[self pathForCacheFile:@"myWishlist1.bin"]];
NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
// userObject is the object we want to save...
[defaults setObject:[NSKeyedArchiver archivedDataWithRootObject:newArr] forKey:@"myWishlist1.bin"];
[defaults synchronize];
}
else
{
[temp addObject:mywishlist];
[NSKeyedArchiver archiveRootObject:temp toFile:[self pathForCacheFile:@"myWishlist1.bin"]];
NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
// userObject is the object we want to save...
[defaults setObject:[NSKeyedArchiver archivedDataWithRootObject:temp] forKey:@"myWishlist1.bin"];
[defaults synchronize];
}
}
}
- (IBAction)BACKO:(id)sender {
[self saveInWishlist];
NSLog(@"ICIII %@",wishexpo);
wishlist * car2=[[wishlist alloc]init];
car2.exponom=wishexpo;
car2.idvoiture=TelephoneFix;
car2.imvoiture=dataimage;
car2.objid=objectId;
[NSKeyedArchiver archiveRootObject:car2 toFile:@"

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Wishlist"
message:@"This car has been successfully added to your wishlist"
delegate:self

I have the same error when using NSKeyedArchiver
and only with iOS8. In my case, I was doing this:
[defaultManager changeCurrentDirectoryPath:customDirectory];
[NSKeyedArchiver archiveRootObject:blankDictionary toFile:filename];
But it worked when I did this:
NSString fullPath = [NSString stringWithFormat:@"%@/%@", customDirectory, filename];
[NSKeyedArchiver archiveRootObject:blankDictionary toFile:fullPath];
I am guessing the error is in NSKeyedArchiver
and relative paths are not working. If there are relative paths in the search path, try taking them out.
