So I am having this custom made class:
LocationSupplementaryObject.h:
@interface LocationSupplementaryObject : NSObject <NSCoding>
@property (nonatomic) NSString* storedPlaceName;
-(id)initWithLocationName:(NSString*)locationName;
-(void)encodeWithCoder:(NSCoder*)encoder;
-(id)initWithCoder:(NSCoder*)decoder;
- (void)saveCustomObject:(LocationSupplementaryObject *)object key:(NSString *)key;
- (LocationSupplementaryObject *)loadCustomObjectWithKey:(NSString *)key;
@end
LocationSupplementaryObject.m:
@implementation LocationSupplementaryObject
- (id)initWithLocationName:(NSString *)locationName
{
self = [super init];
if (self) {
self.storedPlaceName = locationName;
NSLog(@"Initialization success! Name is %@",self.storedPlaceName);
}
return self;
}
-(void)encodeWithCoder:(NSCoder *)encoder {
// Encode the properties of the object
[encoder encodeObject:self.storedPlaceName forKey:@"stored_placeName"];
}
-(id)initWithCoder:(NSCoder *)decoder {
self = [super init];
if (self) {
// Decode properties for the object
self.storedPlaceName = [decoder decodeObjectForKey:@"stored_placeName"];
}
return self;
}
- (void)saveCustomObject:(LocationSupplementaryObject *)object key:(NSString *)key {
NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:encodedObject forKey:key];
[defaults synchronize];
}
- (LocationSupplementaryObject *)loadCustomObjectWithKey:(NSString *)key {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSData *encodedObject = [defaults objectForKey:key];
LocationSupplementaryObject *object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
return object;
}
@end
So later in my program I am using LocationSupplementaryObject class:
LocationSupplementaryObject *suppObject = [[LocationSupplementaryObject alloc]initWithLocationName:[object objectForKey:(NSString*)kCCName]];
// Writing the object to defaults
[suppObject saveCustomObject:suppObject key:@"StoredLocation"];
NSLog(@"%@ Successfully packed",suppObject.storedPlaceName);
LocationSupplementaryObject *newObject = [[LocationSupplementaryObject alloc]init];
[newObject loadCustomObjectWithKey:@"StoredLocation"];
NSLog(@"Re initializing from defaults %@",newObject.storedPlaceName);
To initialise the name, I am taking object, loaded from the parse.com, we could see that suppObject.storedPlaceName is set correctly trough NSLog message. But, name retrieved and unarchived from NSUserDefaults turns out to be (null), I know that NSUserDefaults could be slow, even though we called synchronise so I am checking for the object in another side of program:
LocationSupplementaryObject *suppObject = [[LocationSupplementaryObject alloc]init];
[suppObject loadCustomObjectWithKey:@"StoredLocation"];
if (suppObject) {
NSLog(@"We got our name %@",suppObject.storedPlaceName);
}
And even though class was initialised with a legit NSString, it still shows me (null) for the name stored in NSUserDefaults. I should admit, that I doesn't have a lot of experience with NSCoder, so any help will be appreciated.
