iOS - Use responseObject outside of AFNetworking - ios

I want to display the responseObject received from the below AFNetworking call in my tableview cell. I created an NSMutableArray property in my header file (neighbourData) thinking allocating responseObject to it might work. Though as predicted, I can't seem to use the data outside of the AFNetworking method. On the other hand, placing the AFNetworking method inside of my tableview cell works, but there is a lag time in waiting for the data to display in my UIlabels. Any ideas?
ViewController.h
#property (strong, nonatomic) NSMutableArray *neighbourData;
ViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableDictionary *viewParams = [NSMutableDictionary new];
[viewParams setValue:#"u000" forKey:#"view_name"];
[DIOSView viewGet:viewParams success:^(AFHTTPRequestOperation *operation, id responseObject) {
self.neighbourData = [responseObject mutableCopy];
NSLog(#"This is the neighbourdata %#",self.neighbourData);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", [error localizedDescription]);
}];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *NetworkTableIdentifier = #"sidebarCell";
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
sidebarCell *cell = (sidebarCell *)[tableView dequeueReusableCellWithIdentifier:NetworkTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"sidebarCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
NSDictionary *userName = [self.neighbourData objectAtIndex:indexPath.row];
[[cell username] setText:[userName objectForKey:#"users_name"]];
NSDictionary *userBio = [self.neighbourData objectAtIndex:indexPath.row];
[[cell userDescription] setText:[userBio objectForKey:#"userbio"]];
return cell;
}

You can initialise neighbourData with the responce object or just pass its refrence to your arry and then reload the table. it will work
self.neighbourData = [NSMutableArray alloc]initWithArry: responseObject]];
[yourTableView reloadData];
OR
self.neighbourData = (NSMutableArray *)responseObject;
[yourTableView reloadData];

tableview reloadData not working after successful login / AFNetworking

I'm using the below code in my ViewController.m to log a user in to my app. However on the following ViewController (AccountViewController), I have a tableView. Upon successful login, I want to reload/populate the data in the tableView, but instead after a successful login, I get an empty table. I've put reloadData in viewWillAppear at the top of MyAccountViewController. See below. Not sure why it's doing this, as when I navigate from AccountViewController to another screen and back, the table is populated. Is my AFNetworking bit causing the table not to populate for some reason?
ViewController.m

You have a "refresh" observer, but it calls a function you haven't shown here. You set your data it looks like with this:
for (id object in responseObject) {
// NSLog(#"adding object!");
[self.storageData setObject:(NSDictionary *)object forKey:[NSString stringWithFormat:#"%d",iCount]];
iCount++;
[self.tableView reloadData];
}
but because that is in viewDidLoad, it is only called once, BEFORE viewWillAppear. You need to fill self.storageData and self.descripData in a separate function, then call THAT function from viewWillAppear, or using your NSNotificationCenter notification from the previous VC.

Crash error: [__NSCFArray objectAtIndex:]: index (10) beyond bounds (10)'

I know this seems to be a fairly common error, but I'm going crazy trying to sort out why I'm getting this message. As I scroll down my tableView, the console throws me this:
Terminating app due to uncaught exception 'NSRangeException', reason: '-[__NSCFArray objectAtIndex:]: index (10) beyond bounds (10)'
Any idea how I can fix this? I'm trying to get the number of items in the array storageData (e.g. return [storageData count];) See code below.
ViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
self.storageData = [[NSMutableDictionary alloc] init];

//failure
}];
}

Data not populating on TableView

I am fetching data from the website and loading on the tableViewController. Tableviewcontroller is inside the tabbarcontroller. Whenever I clickked on tabbar, tableview data does not populated. However once I click other viewcontrollers and then click again on tableviewcontroller, then data populated.

You aren't doing anything once you receive a response from the network and populate your array?
What you need to do is notify the table view that it needs to query its data source again to refresh its values. Simply calling reloadData on your table view once you have your array would to the trick:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:#"http://ilyasuyanik.com/coursera/books.php" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
if ([[responseObject valueForKey:#"status"] isEqualToString:#"success"]) {
int count = [[responseObject valueForKey:#"total"] integerValue];
NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:count];
for (int i = 1; i <= count; i++) {
NSString *obj = [NSString stringWithFormat:#"%i", i];
[array addObject:[responseObject objectForKey:obj]];
}
dispatch_async(dispatch_get_main_queue,^{
booksArray = array;
for (id obj in booksArray) {
NSLog(#"%#", [obj valueForKey:#"title"]);
}
//now you can update your table view
[self.tableView reloadData];
});
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Issue with Pagintation

I am trying to use the Instagram API for Pagination in my iOS App. However whenever I add my new pictures to my existing array I get this Error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[__NSCFArray insertObject:atIndex:]: mutating method sent to immutable object'
Here is my code on how to get the initial set of Instagram Images:
- (void)fetchInstagramPics {
NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
BOOL *status = [user boolForKey:#"isInstagramLoggedIn"];
if (status) {
[[InstagramClient sharedClient] getPath:#"users/self/feed"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
// NSLog(#"Response: %#", responseObject);
self.timelineResponse = [responseObject mutableCopy];
[instaPics addObjectsFromArray:responseObject[#"data"]];
[self updateArrays];
[self.tableView reloadData];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", error);
}];
}
dispatch_async(dispatch_get_main_queue(), ^{
[self.tableView reloadData]; });
}
Here is how I am attempting to add more pictures into the instaPics Array:
- (void)nextInstagramPage:(NSIndexPath *)indexPath{
NSDictionary *page = self.timelineResponse[#"pagination"];
NSString *nextPage = page[#"next_url"];
[[InstagramClient sharedClient] getPath:[NSString stringWithFormat:#"%#",nextPage] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
self.timelineResponse = [responseObject mutableCopy];
[self.timelineResponse addEntriesFromDictionary:responseObject];
[instaPics addObjectsFromArray:responseObject[#"data"]];
[self.tableView reloadData];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", error);
}];
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
if (scrollView.contentOffset.y == roundf(scrollView.contentSize.height-scrollView.frame.size.height)) {
NSLog(#"we are at the endddd");
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self nextInstagramPage:indexPath];
}
}
Here are all the properties defined in the Header file of this class:
#property (strong, nonatomic) NSMutableArray *instaPics;
#property (strong, nonatomic) AFOAuth1Client *twitterClient;
#property (strong, nonatomic) IBOutlet UINavigationItem *navBar;
#property (strong, nonatomic) NSMutableArray *tweets;
//Edit: Now have the construction of the Cells:
if (indexPath.row % 2 == 0) {
static NSString *CellIdentifier = #"TweetCell";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"Background.png"]];
NSDictionary *tweet = tweets[indexPath.row];
return cell;
}else {
static NSString *CellIdentifier = #"InstagramCell";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"Background.png"]];
NSDictionary *entry = instaPics[indexPath.row];
return cell;
}
}
You have to initialize the NSMutableArray, add instaPics = [[NSMutableArray alloc] init]; in fetchInstagramPics

How can i retrieve a image from Parse.com via query at iOS?

I am using Parse.com for retrieving my data.I want to retrieve my images from parse via pf query but my approach does not working.I get nothing where my UIImageView is. Here is my code:
PFQuery *query = [PFQuery queryWithClassName:#"Class"];
[query whereKey:#"Yes or No" equalTo:[NSNumber numberWithBool:YES]];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
// The find succeeded.
NSLog(#"Successfully retrieved %d scores.", objects.count);
for (int i = 0; i < objects.count; i++) {
object = [objects objectAtIndex:i];
NSString *Property1 = [object objectForKey:#"Property1"];
__block UIImage *MyPicture = [[UIImage alloc]init];
PFFile *imageFile = [object objectForKey:#"Resimler"];
[imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error){
if (!error) {
MyPicture = [UIImage imageWithData:data];
}
}];
aClass *AC = [[aClass alloc]initWithProperty:Propert1 Picture:MyPicture];
[self.MyArray addObject:AC];
}
}
} else {
// Log details of the failure
NSLog(#"Error: %# %#", error, [error userInfo]);
}
}];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
MyViewViewCell *cell = (MyViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"Cell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
aClass *mC = [self.MyArray objectAtIndex:indexPath.row];
cell.Label.text = mC.Property;
cell.myImage.image = mC.Picture;
return cell;
}
Edit:
At aClass.h
#interface aClass : NSObject
#property(strong)NSString *Property;
#property(strong)UIImage *Resim;
-(id)initWithProperty:(NSString *)aProperty Picture:(UIImage *)aPicture ;
#end
at aClass.m
#implementation Mekan
#synthesize Property, Picture;
-(id)initWithMekanIsmi:(NSString *)aProperty Picture:(UIImage *)aPicture{
self=[super init];
if(self){
self.Property = aProperty;
self.Picture = aPicture;
}
return self;
}
#end
I know it is kind of a mass code but i have to write those codes to illustrate where i assign myImage. So you can ask where you do not understand
I do it like this:
UIImageView *imageView = [[UIImageView alloc] initWithImage:#"default.png"];
[userIcon getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
imageView.image = [[UIImage alloc] initWithData:data];
} progressBlock:^(int percentDone) {
// update progress
}];
You seem to be assigning it to a UIImage properly, but never setting that image as the image for a UIImageView.
