iOS Convert Facebook Graph JSON result to NSMutableArray - ios

Question

I use
if ([FBSDKAccessToken currentAccessToken]) {
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/v2.3/116178611870507/feed?limit=2" parameters:[NSMutableDictionary dictionaryWithObject:#"id, message, picture" forKey:#"fields"]]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"fetched user:%#", result);
}
else {
NSLog(#"%#", error);
}
}];
}
and get:
{
data = (
{
"created_time" = "2015-08-08T13:19:59+0000";
id = "FirstID";
message = "First Message";
},
{
"created_time" = "2015-08-07T13:34:20+0000";
id = "THE ID";
message = "Message Content";
}
);
I would like to get this into an NSMutableArray to allow for easier creation of a tableview, using this data. How can I go about converting it, as it contains a lot of non UTF-8 such as \u2019?
Here is the non-edited result code I get for the open graph request. As you can see in it, there are numerous non UTF-8 elements such as /u2019 instead of '. I just need to put this into an array, while converting all those elements.:
{
data = (
{
"created_time" = "2015-08-08T13:19:59+0000";
id = "116178611870507_533557810132583";
message = "10 HABITS OF HAPPY COUPLES\n\nWhat does it take to be happy in a relationship? If you\U2019re working to improve your marriage, here are the 10 habits of happy couples.\n\n1. GO TO BED AT THE SAME TIME. Remember the beginning of your relationship, when you couldn\U2019t wait to go to bed with each other to make love? Happy couples resist the temptation to go to bed at different times. They go to bed at the same time, even if one partner wakes up later to do things while their partner sleeps. And when their skins touch it still causes each of them to tingle and unless one or both are completely exhausted to feel sexually excited.\n\n2. CULTIVATE COMMON INTERESTS. After the passion settles down, it\U2019s common to realize that you have few interests in common. But don\U2019t minimize the importance of activities you can do together that you both enjoy. If common interests are not present, happy couples develop them. At the same time, be sure to cultivate interests of your own; this will make you more interesting to your mate and prevent you from appearing too dependent.\n\n3. WALK HAND IN HAND OR SIDE BY SIDE. Do things together. Rather than one partner lagging or dragging behind the other, happy couples walk comfortably hand in hand or side by side. They know it\U2019s more important to be with their spouse than to see the sights along the way.\n\n4. MAKE TRUST AND FORGIVENESS YOUR DEFAULT MODE. If and when they have a disagreement or argument, and if they can\U2019t resolve it, happy couples default to trusting and forgiving rather than distrusting and begrudging.\n\n5. FOCUS MORE ON WHAT YOUR SPOUSE DOES RIGHT THAN WHAT HE OR SHE DOES WRONG. If you look for things your partner does wrong, you can always find something. If you look for what he or she does right, you can always find something, too. It all depends on what you want to look for. Happy couples accentuate the positive.\n\n6. HUG EACH OTHER AS SOON AS YOU SEE EACH OTHER AFTER WORK. Our skin has a memory of \U201cgood touch\U201d (loved), \U201cbad touch\U201d (abused) and \U201cno touch\U201d (neglected). Couples who say hello with a hug keep their skin bathed in the \U201cgood touch,\U201d which can inoculate your spirit against anonymity in the world.\n\n7. SAY \"I LOVE YOU\" AND \"HAVE A GOOD DAY\" EVERY MORNING. This is a great way to buy some patience and tolerance as each partner sets out each day to battle traffic jams, long lines and other annoyances.\n\n8. SAY \"GOOD NIGHT\" EVERY NIGHT, REGARDLESS OF HOW YOU FEEL. This tells your partner that, regardless of how upset you are with him or her, you still want to be in the relationship. It says that what you and your partner have is bigger than any single upsetting incident.\n\n9. DO A \"WEATHER\" CHECK DURING THE DAY. Call your spouse at home or at work to see how his or her day is going. This is a great way to adjust expectations so that you\U2019re more in sync when you connect after work. For instance, if your partner is having an awful day, it might be unreasonable to expect him or her to be enthusiastic about something good that happened to you.\n\n10. BE PROUD TO BE SEEN WITH YOUR SPOUSE. Happy couples are pleased to be seen together and are often in some kind of affectionate contact \U2014 hand on hand or hand on shoulder or knee or back of neck. They are not showing off but rather just saying that they belong with each other.\n\nHappy couples have different habits than unhappy couples. A habit is a discrete behavior that you do automatically and that takes little effort to maintain. It takes 21 days of daily repetition of a new a behavior to become a habit. So select one of the behaviors in the list above to do for 21 days and voila, it will become a habit\U2026and make you happier as a couple. And if you fall off the wagon, don\U2019t despair, just apologize to your partner, ask their forgiveness and recommit yourself to getting back in the habit. ~ Dr. Mark Goulson";

Here is my full code. Since there are 2 posts, I expect to have 2 objects in my NSMutableArray, and for each object in the array, use the RSSEntry class to sort through and create a new NSMutableArray from that. However, I only get 1 item in the NSMutableArray I create.
if ([FBSDKAccessToken currentAccessToken]) {
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/v2.3/116178611870507/feed?limit=2" parameters:[NSMutableDictionary dictionaryWithObject:#"id, message, picture" forKey:#"fields"]]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
// NSLog(#"fetched user:%#", result);
self.arrayName = [[NSMutableArray alloc] init];
[self.arrayName addObject:[result objectForKey:#"data"]];
// NSLog(#"%#", self.arrayName);
int i;
NSLog(#"%lu", (unsigned long)[self.arrayName count]);
for (i = 0; i < [self.arrayName count]; i++) {
id myArrayElement = [self.arrayName objectAtIndex:i];
NSString *theMessage = [myArrayElement valueForKey:#"message"];
// NSLog(#"%#", theMessage);
RSSEntry *entry = [[[RSSEntry alloc] initWithBlogTitle:#"Test"
articleTitle:#"Testing"
articleUrl:#"TestingURL"
articleDate:[NSDate date]
articleImage:theMessage] autorelease];
[self.theEntries addObject:entry];
}
NSLog(#"%#", self.theEntries);
}
else {
NSLog(#"%#", error);
}
}];
}

Answer 1

The problem is these two lines:
self.arrayName = [[NSMutableArray alloc] init];
[self.arrayName addObject:[result objectForKey:#"data"]];
You create an array and then you add an array to that one ([result objectForKey:#"data"] returns an array).
Replace those two lines with:
self.arrayName = [result[#"data"] mutableCopy];
Now self.arrayName will contain an array with the two desired dictionaries.
You can also improve your code by using more modern syntax:
if (!error) {
// NSLog(#"fetched user:%#", result);
self.arrayName = [result[#"data"] mutableCopy];
// NSLog(#"%#", self.arrayName);
NSLog(#"%lu", (unsigned long)self.arrayName.count);
for (NSDictionary *myArrayElement in self.arrayName) {
NSString *theMessage = myArrayElement[#"message"];
// NSLog(#"%#", theMessage);
RSSEntry *entry = [[[RSSEntry alloc] initWithBlogTitle:#"Test"
articleTitle:#"Testing"
articleUrl:#"TestingURL"
articleDate:[NSDate date]
articleImage:theMessage] autorelease];
[self.theEntries addObject:entry];
}
NSLog(#"%#", self.theEntries);
} else {
NSLog(#"%#", error);
}
