  • json service from data scraping with php

    - by fredz0003
    I am trying to figure out what is the best way to make this work, I am new to php. I was able to make my script work to find specific data on my htm file with the following script tested on my local server. <?php include ('simple_html_dom.php'); //create DOM from URL or local file $html = file_get_html ('Lotto Texas.htm'); //find td class name currLotWinnum and store in variable winNumbers foreach($html ->find('td.currLotWinnum') as $winNumbers) //print winNumbers echo "<b>The winning numbers are</b><br>"; echo $winNumbers -> innertext . '<br>'; ?> Need some light here, ultimately I would like to create a web service to return json format and access that data from my iOS application using NSJSONSerialization class.

  • IOS - Performance Issues with SVProgressHUD

    - by ScottOBot
    I have a section of code that is producing pour performance and not working as expected. it utilizes the SVProgressHUD from the following github repository at https://github.com/samvermette/SVProgressHUD. I have an area of code where I need to use [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]. I want to have a progress hud displayed before the synchronous request and then dismissed after the request has finished. Here is the code in question: //Display the progress HUB [SVProgressHUD showWithStatus:@"Signing Up..." maskType:SVProgressHUDMaskTypeClear]; NSError* error; NSURLResponse *response = nil; [self setUserCredentials]; // create json object for a users session NSDictionary* session = [NSDictionary dictionaryWithObjectsAndKeys: firstName, @"first_name", lastName, @"last_name", email, @"email", password, @"password", nil]; NSData *jsonSession = [NSJSONSerialization dataWithJSONObject:session options:NSJSONWritingPrettyPrinted error:&error]; NSString *url = [NSString stringWithFormat:@"%@api/v1/users.json", CoffeeURL]; NSURL *URL = [NSURL URLWithString:url]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setValue:[NSString stringWithFormat:@"%d", [jsonSession length]] forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:jsonSession]; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *dataString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSDictionary *JSONResponse = [NSJSONSerialization JSONObjectWithData:[dataString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&error]; NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response; NSInteger statusCode = httpResponse.statusCode; NSLog(@"Status: %d", statusCode); if (JSONResponse != nil && statusCode == 200) { //Dismiss progress HUB here [SVProgressHUD dismiss]; return YES; } else { [SVProgressHUD dismiss]; return NO; } For some reason the synchronous request blocks the HUB from being displayed. It displays immediately after the synchronous request happens, unfortunatly this is also when it is dismissed. The behaviour displayed to the user is that the app hangs, waits for the synchronous request to finish, quickly flashes the HUB and then becomes responsive again. How can I fix this issue? I want the SVProgressHUB to be displayed during this hang time, how can I do this?

  • populate CoreData data model from JSON files prior to app start

    - by johannes_d
    I am creating an iPad App that displays data I got from an API in JSON format. My Core Data model has several entities(Countries, Events, Talks, ...). For each entity I have one .json file that contains all instances of the entity and its attributes as well as its relationships. I would like to populate my Core Data data model with these entities before the start of the App (otherwise it takes about 15 minutes for the iPad to create all the instances of the entities from the several JSON files using factory methods). I am currently importing the data into CoreData like this: -(void)fetchDataIntoDocument:(UIManagedDocument *)document { dispatch_queue_t dataQ = dispatch_queue_create("Data import", NULL); dispatch_async(dataQ, ^{ //Fetching data from application bundle NSURL *tedxgroupsurl = [[NSBundle mainBundle] URLForResource:@"contries" withExtension:@"json"]; NSURL *tedxeventsurl = [[NSBundle mainBundle] URLForResource:@"events" withExtension:@"json"]; //converting the JSON files to NSDictionaries NSError *error = nil; NSDictionary *countries = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:countriesurl] options:kNilOptions error:&error]; countries = [countries objectForKey:@"countries"]; NSDictionary *events = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:eventsurl] options:kNilOptions error:&error]; events = [events objectForKey:@"events"]; //creating entities using factory methods in NSManagedObject Subclasses (Country / Event) [document.managedObjectContext performBlock:^{ NSLog(@"creating countries"); for (NSDictionary *country in countries) { [Country countryWithCountryInfo:country inManagedObjectContext:document.managedObjectContext]; //creating Country entities } NSLog(@"creating events"); for (NSDictionary *event in events) { [Event eventWithEventInfo:event inManagedObjectContext:document.managedObjectContext]; // creating Event entities } NSLog(@"done creating, saving document"); [document saveToURL:document.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:NULL]; }]; }); dispatch_release(dataQ); } This combines the different JSON files into one UIManagedDocument which i can then perform fetchRequests on to populate tableViews, mapView, etc. I'm looking for a way to create this document outside my application & add it to the mainBundle. Then I could copy it once to the apps DocumentsDirectory and be able I use it (instead of creating the Document within the app from the original JSON files). Any help is appreciated!

How to fix it? Sorry for bad english.

  • Getting a UIImage from MySQL using PHP and jSON

    - by Daniel
    I'm developing a little news reader that retrieves the info from a website by doing a POST request to a URL. The response is a jSON object with the unread-news. E.g. the last news on the App has a timeStamp of "2013-03-01". When the user refreshes the table, it POSTS "domain.com/api/api.php?newer-than=2013-03-01". The api.php script goes to the MySQL database and fetches all the news posted after 2013-03-01 and prints them json_encoded. This is // do something to get the data in an array echo $array_of_fetched_data; for example the response would be [{"title": "new app is coming to the market", "text": "lorem ipsum dolor sit amet...", image: XXX}] the App then gets the response and parses it, obtaining an NSDictionary and adds it to a Core Data db. NSDictionary* obtainedNews = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error]; My question is: How can I add an image to the MySQL database, store it, pass it using jSON trough a POST HTTP Request and then interpret it as an UIImage. It's clear that to store an UIImage in CoreData, they must be transform into/from NSData. How can I pass the NSData back and forth to a MySQL db using php and jSON? How should I upload the image to the db? (Serialized, as a BLOB, etc)

  • Cannot access NSDictionary

    - by michael blaize
    I created a JSON using a PHP script. I am reading the JSON and can see that the data has been correctly read. However, when it comes to access the objects I get unrecognized selector sent to instance... Cannot seem to find why that is after too many hours !!!! Any help would be great ! My code looks like that: `NSDictionary *json = [[NSDictionary alloc] init]; json = [NSJSONSerialization JSONObjectWithData:receivedData options:kNilOptions error:&error]; NSLog(@"raw json = %@,%@",json,error); NSMutableArray *name = [[NSMutableArray alloc] init]; [name addObjectsFromArray: [json objectForKey:@"name"]];` The code crashes when reaching the last line above. The output like this: raw json = ( { category = vacancies; link = "http://blablabla.com"; name = "name 111111"; tagline = "tagline 111111"; }, { category = vacancies; link = "http://blobloblo.com"; name = "name 222222222"; tagline = "tagline 222222222"; } ),(null) 2012-06-23 21:46:57.539 Wind expert[4302:15203] -[__NSCFArray objectForKey:]: unrecognized selector sent to instance 0xdcfb970 HELP !!!

  • SLRequest return nil before block complete

    - by jaytr0n
    I'm having a little trouble thinking through this and deciding if it's a design flaw on my behalf or if I'm missing a piece that could make this work. Basically I'm using the new SLRequest to make a Twitter API call. After the data is returned, I'd like to put it into an object and return that object: -(AUDSlide *) getFollowerSlide { SLRequest *getRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/followers/ids.json?user_id=%@", [[self.twitterAccount valueForKey:@"properties"] valueForKey:@"user_id"]]] parameters:nil]; getRequest.account = twitterAccount; AUDSlide *slide = [[AUDSlide alloc] init]; [getRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if ([urlResponse statusCode] == 200) { NSError *jsonError = nil; NSDictionary *list = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&jsonError]; NSLog(@"Number of Followers: %u", [[list objectForKey:@"ids"] count]); slide.title = @"Followers"; slide.number = [NSString stringWithFormat:@"%u",[[list objectForKey:@"ids"] count]]; } else{ slide.title = @"Error"; slide.number = [NSString stringWithFormat: @"E%u", [urlResponse statusCode]]; } }]; return slide; } Of course the slide is returned before the call is complete and returns a nil object. So I'm not sure if I should try to force this into a synchronous request (that seems like it could be a bad idea) or rethink the design. Does anyone have any advice?

  • Simple iOS Get Request Not Pulling in Data

    - by user2793987
    I have a very simple get request that doesn't return data on my script. The script is fine when viewed in the web browser but the app does not pull in the data. Any other script works with this code in the app. I'm unsure of what to do because there shouldn't be a reason for this to not work. Please let me know if you need more information. Here's the script: https://shipstudent.com/complaint_desk/similarPosts.php?username=noah //retrieve saved username from user defaults (it's noah) NSUserDefaults *eUser = [NSUserDefaults standardUserDefaults]; savedUser = [eUser objectForKey:@"user"]; NSLog(@"%@",savedUser); in ViewDidLoad: NSString *categoryParam = [NSString stringWithFormat:@"https://shipstudent.com/complaint_desk/similarPosts.php?username=%@", savedUser]; NSURL *url = [NSURL URLWithString:categoryParam]; NSMutableURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageAllowed timeoutInterval:30.0]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (connection==nil) { NSLog(@"Invalid request"); } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { postData = [[NSMutableData alloc]init]; NSLog(@"Response received"); } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [postData appendData:data]; NSLog(@"Data received"); } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; similarPosts = [NSJSONSerialization JSONObjectWithData:postData options:kNilOptions error:nil]; [postsTbl reloadData]; for (id postObject in similarPosts) { NSLog(@"Relatable Post: %@",postObject); } }
