NSLOG le cache d'une application
Bonjour !
dans mon app, j'essaye de mettre en cache des informations afin que l'utilisateur puisse continuer à utiliser l'app sans réseau disponible.
Je vous donne un bout du code que j'ai écris :
Le log qui cache les id Facebook -
-(void)facebookRequestDidLoad:(id)result{
PFUser *user = [PFUser currentUser];
NSArray *data = [result objectForKey:@data];
if(data){
NSMutableArray *facebookIds = [[NSMutableArray alloc] initWithCapacity:[data count]];
for (NSDictionary *friendData in data ) {
if (friendData[@id]){
[facebookIds addObject:friendData[@id]];
NSLog(@facebookIds : %@", facebookIds);
}
}
[[AACache sharedChache] setFacebookFriends:facebookIds];
if (user) {
if ([user objectForKey:AAUserFacebookFriendsKey]) {
[user removeObjectForKey:AAUserFacebookFriendsKey];
}
NSError *error = nil;
PFQuery *facebookFriendsQuery = [PFUser query];
[facebookFriendsQuery whereKey:AAUserFacebookIDKey containedIn:facebookIds];
NSLog(@liste facebookID : %@", facebookIds);
NSMutableArray *simpleSharingListFriends = [[NSMutableArray alloc] init];
[facebookFriendsQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
NSLog(@comptage : %lu, [objects count]);
[simpleSharingListFriends removeAllObjects];
[simpleSharingListFriends addObjectsFromArray:objects];
NSLog(@liste amis tableau : %@", simpleSharingListFriends);
}
}];
if (!error) {
[simpleSharingListFriends enumerateObjectsUsingBlock:^(PFUser *newFriend, NSUInteger idx, BOOL *stop) {
PFObject *joinActivity = [PFObject objectWithClassName:AAActivityClassKey];
[joinActivity setObject:user forKey:AAActivityFromUserKey];
[joinActivity setObject:newFriend forKey:AAActivityToUserKey];
[joinActivity setObject:AAActivityTypeJoined forKey:AAActivityTypeKey];
PFACL *joinACL = [PFACL ACL];
[joinACL setPublicReadAccess:YES];
joinActivity.ACL = joinACL;
[joinActivity saveInBackground];
NSLog(@liste amis %@", simpleSharingListFriends);
}];
}
[user saveEventually];
}
}
else {
if (user) {
NSString *facebookName = result[@name];
if (facebookName && [facebookName length] != 0) {
[user setObject:facebookName forKey:AAUserNameKey];
NSLog(@facebook Name : %@", facebookName);
}else {
[user setObject:@Someone forKey:AAUserNameKey];
}
NSString *facebookId = result[@id];
if (facebookId && [facebookId length] != 0) {
[user setObject:facebookId forKey:AAUserFacebookIDKey];
NSLog(@facebook Id : %@", facebookId);
}
[user saveEventually];
}
[FBRequestConnection startForMyFriendsWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
[self facebookRequestDidLoad:result];
} else {
[self facebookRequestDidFailWithError:error];
}
}];
}
}

Par quel moyen est-ce que je peux suivre ce qu'il se passe dans la partie cache de l'application ?
