AFNetworking, NSURLSession and json Response (Ronak Sankhala) - json

I am trying to get json response from a web-service api. I want to extract product data from the json. I also want to implement this using AFNetworking and i also trying to get response using NSURLSession and its completely working.

Can anyone suggest a way to do this.me how the things will be done.

You Can use also use sqlite for the data.

pull to refresh uitableview json parsing data

i'm using json rss feed parsing in my rss app, i have table view loading titles , thumbnails and sending links of titles to a web view each in it's own nsmutable array, however , i'm adding a pull to refresh in my app , i followed alot of tutorials , i added the code, when i pull , i get the spinning wheel , and loads and stops, but my new feed isn't loaded, how do i make sure the parsing method gets recalled , bnot just refreshen table happens , below is my code :

i found the answer , i had to empty the table view , and recall the nsurl , reload data and end refreshing , it works perfectly now
here is the code everyone:
- (void)refresh {
[feeds removeAllObjects];
NSURL *url = [NSURL URLWithString:#"http://icuore.ly/category/ipad/feed/"];
parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
[parser setDelegate:self];
[parser setShouldResolveExternalEntities:NO];
[parser parse];
[self.tableView reloadData];
[refreshControl endRefreshing];
NSLog(#"fetching data from the server");

Cannot get UISearchBar code working

xcode newbie trying to get UISearchBar functionality working.
I am using storyboards and my tableview controller shows a list of events (title, location & start date)in the cells from the array json. When the table firsts loads all of my results are displayed ok. When I click put some text into the search bar (text that exists in the title) nothing is shown in the view controller (I.e. it filters all of the events out). Hopefully this makes a bit more sense.
My header file is
#import <UIKit/UIKit.h>
#define kGETUrl #"http://www.max-momentus.com/fetchevents.php5"
#interface MMAllEventsViewController : UITableViewController <UISearchBarDelegate, UITableViewDelegate, UITableViewDataSource> {

Have you made sure you have the delegates: in your view controllers .h file? Also, make sure you've selected the "UISearchBar and UISearchDisplay Controller" as your search bar object from the storyboard (assuming you're using storyboards). Make sure you've linked your SearchBar to have your view controller be its delegate, and it's connected to an IBOutlet object in your code (again, assuming your using storyboards:
#property (strong, nonatomic) IBOutlet UISearchBar *searchBar;
Finally, make that you have declared a UISearchDisplayController variable, linked it to your UITableView and then make sure when loading the results from a search, to check in your
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
and
- (NSInteger)numberOfRowsInTableView:(UITableView *)tableView
if:
if(tableView == searchDisplay):
{
...load results.
}
else
{
...load normal view

loading phpMyAdmin-database to UITableView

I developed an App in xcode 4.2 that reads data from a phpMyAdmin database and loads it to a tableview. Now if I do the same inxcode 4.3, it doesn't work anymore. I am looking for a solution since days now, but can't find any and I have no idea why it doesn't work (my database and php script works fine).

NSMutableArray *myArray;
FirstViewController.m:

NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error;
myArray = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions
error:&error];
[self.tableView reloadData];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [myArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

Parsed results in UITableView

I am using HTMLParser by Ben Reeves. It works great but the only problem is that I couldn't put the output in UITableView. Anyone can tell me what's wrong with this code? ...................................................................................
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSError *error = nil;
NSURL *url=[[NSURL alloc] initWithString:#"http://website.com/"];
NSString *strin=[[NSString alloc] initWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
HTMLParser *parser = [[HTMLParser alloc] initWithString:strin error:&error];
if (error) {
NSLog(#"Error: %#", error);
return;
}
HTMLNode *bodyNode = [parser body];
NSArray *divNodes = [bodyNode findChildTags:#"div"];
for (HTMLNode *inputNode in divNodes) {
if ([[inputNode getAttributeNamed:#"class"] isEqualToString:#"views-field-title"]) {
NSLog(#"%#", [inputNode allContents]);
listData = [[NSArray alloc] initWithObjects:[inputNode allContents], nil];
}
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.listData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [listData objectAtIndex:row];
return cell;
}
#end
You're reinitializing your array every time you find a new element. I think you need to move
listData = [[NSArray alloc] initWithObjects:[inputNode allContents], nil];
outside of your loop and change it to
listData = [[NSMutableArray alloc] init];
listData should be an NSMutableArray so you can add data to it. You'll need to change this in your variable definition too.
Then inside your loop, use [listData addObject:[inputNode allContents]];

IOS Loading data into a table from a web service

I'm very new to this, so pardon my ignorance.
I have the following method that I've pieced together and I get no errors when it's running, and I verified that I'm getting data from the web service. What I do notice is that when I put a breakpoint on the numberOfRowsInSection method it returns 0 both times. I assume that means I'm not loading my array correctly.
Declare my messages property in the header
#property (nonatomic, strong) NSArray *messages;
Synthesize that property in the m file
#synthesize messages;
This is the method that loads the data and is supposed to reload the table
- (void)request:(RKRequest*)request didLoadResponse:(RKResponse*)response
{
if ([response isOK])
{
// Success! Let's take a look at the data
NSDictionary *result = [NSJSONSerialization JSONObjectWithData: [[response bodyAsString] dataUsingEncoding:NSUTF8StringEncoding] options: NSJSONReadingMutableContainers error:nil];
if([[result objectForKey:#"result"] isEqualToString:#"success"])
{
NSArray *message_array = [result objectForKey:#"messages"];
for(NSUInteger i = 0; i < [message_array count]; i++)
{
EHRXMessage *m = [[EHRXMessage alloc] init];
NSDictionary *message = [message_array objectAtIndex: i];
m.subject = [message objectForKey:#"Title"];
m.callback_name = [message objectForKey:#"CallbackName"];
[self.messages setValue:m forKey:[NSNumber numberWithInt:i]];
}
[self.tableView reloadData];
}
else
{
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:#"Inbox Error!"
message:#"Error loading messages"
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
}
}
}
And here is the method where I tell it how to load the cells
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"MessageCell"];
EHRXMessage *message = [self.messages objectAtIndex:indexPath.row];
cell.textLabel.text = message.callback_name;
cell.detailTextLabel.text = message.subject;
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.messages count];
}
And here's a snippet of what the json looks like
{"result":"success","count":"0", "messages":[{"SenderID":"6fcb7c19-b21f-4640-a237-0e7ac5ca0ce8","Title":"General","Message":"","CallbackName":"Claudia","CallbackNumber":"1295","EncounterID":null,"AdmissionID":"d7387243-3e8a-42e4-8a85-fdd3428dae68","DateSent":"3/9/2012 12:52 PM"}]}
- (void)viewDidLoad
{
[super viewDidLoad];
self.loaded = FALSE;
NSURL *URL = [NSURL URLWithString:#"http://46.136.168.166:8000/test.php"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection start];
// creating loading indicator
self.HUD = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
if(connection){
self.recievedData = [NSMutableData data];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(!cell)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
NSDictionary *item = [self.dataBase objectAtIndex:[indexPath section]];
NSArray *item_d = [item allKeys];
[[cell textLabel] setText:[item objectForKey:[item_d objectAtIndex:[indexPath row]]]];
return cell;
}
- (void)fetchedData:(NSMutableData *)responseData
{
NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error];
[self setDataBase:[json objectForKey:#"json-data-header"]];
[self.table reloadData];
}
Do you have numberOfRowsInSection?
EDIT
Be sure to initialize the data source (self.messages)
