I have integrated MGTwittweEngine for getting the feeds of a twitter page to show in a tableview in my app.This thing was working from 2 months but from 1st june it has stopped working.Kindly suggest what is going wrong with my code.
in viewdidload I am calling
feed_count = 30;
[self setTweets:[[NSMutableArray alloc]init]];
twitterEngine = [[MGTwitterEngine alloc] initWithDelegate:self];
[twitterEngine setUsesSecureConnection:NO];
[twitterEngine setUsername:#"GoodLifeFitness"];
[twitterEngine getUserTimelineFor:[twitterEngine username] sinceID:0 startingAtPage:1 count:feed_count];

I am working on ELCAlbumPickerController, i am able to select multiple images and upload, but in addition i want to get the file name and datatype of the file. how can i do that?
I am able to select either image or video , how can i select both image and video and any file at a time?

You can get the asset URL using the key UIImagePickerControllerReferenceURL which would give the 'name', but that probably won't be very useful as its probably a UUID. The UIImagePickerControllerMediaType key contains the type.
In my app, there is code that, if a button is pressed the user can upgrade the app and remove the advertisements, it calls the MKStoreKit and once the user purchases the upgrade, the adverts do remain in the app UNTIL the app is restarted.
I want to fix this, so the advertisements are removed immediately, but how would I go about doing this?
Here is some of the code;
-(IBAction)removeAds:(id)sender
{
if (![MKStoreManager isFeaturePurchased:#"com.davidsapps.puzzler.removeads"]) { //
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Upgrade App" message:#"To upgrade and remove all advertisements from this app Please click OK to purchase the upgrade!" delegate:self cancelButtonTitle:#"No Thanks" otherButtonTitles:#"Yes Please",nil];
[alert show];
[alert release];
}
}
The alert it links to;
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:#- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:#"com.idevver.mybatterypal.upgrade"];
}
}
}
Using MKStoreKit
Is there anything I can do to make it remove the advertisements without the user having to restart the app?
Thanks,
Chris
EDIT - the advertisements are Admob Mediation, using this code in the ViewDidLoad
- (void)viewDidLoad {
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
bannerView_.adUnitID = MY_BANNER_UNIT_ID;
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGFloat screenHeight = screenRect.size.height;
CGFloat screenXPos = (screenWidth /2);
CGFloat screenYPos = screenHeight - 90;
[bannerView_ setCenter:CGPointMake(screenXPos, screenYPos)];
bannerView_.rootViewController = self;
bannerView_.adUnitID = MY_BANNER_UNIT_ID;
bannerView_.rootViewController = self;
[self.view addSubview:bannerView_];
This is the code that actually calls the advertisement banner, it is in an if/else statement later in the viewDidLoad
if (![MKStoreManager isFeaturePurchased:#"com.davidsapps.puzzler.removeads"]) { //
[bannerView_ loadRequest:[GADRequest request]];
}
So I guess somehow when the feature is purchased, I need to add to the MKStoreManager.m file something to say dismiss the bannerView_ code above?
Would that work?

When the purchase completes, it is up to you to remove the ads. Do something similar to this.
[bannerView removeFromSuperview];
All you have to do is hide the ads when the purchase completes.
My previous question was about the problem that I have to login each time for doing web services like posting a link or uploading a picture. Philipe answered that I have to use cookies instead of login process for each request. I found this method for getting cookies:
- (void)getCookies {
NSHTTPURLResponse * response;
NSError * error;
NSMutableURLRequest *request;
request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"http://MyWebsite.com/login.php"]
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:120];
NSData * data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"%#", [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]);
NSArray * all = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[NSURL URLWithString:#"http://MyWebsite.com/login.php"]];
NSLog(#"%d", all.count);
for (NSHTTPCookie *cookie in all) {
NSLog(#"Name: %# : Value: %#", cookie.name, cookie.value);
NSLog(#"Comment: %# : CommentURL: %#", cookie.comment, cookie.commentURL);
NSLog(#"Domain: %# : ExpiresDate: %#", cookie.domain, cookie.expiresDate);
NSLog(#"isHTTPOnly: %c : isSecure: %c", cookie.isHTTPOnly, cookie.isSecure);
NSLog(#"isSessionOnly: %c : path: %#", cookie.isSessionOnly, cookie.path);
NSLog(#"portList: %# : properties: %#", cookie.portList, cookie.properties);
NSLog(#"version: %u", cookie.version);
}
}
I also found this code to use these cookies, but I'm not sure how to use it:
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookies];
Here is my method for POSTing, I am using RestKit API:
- (IBAction)addLinkPressed:(UIButton *)sender {
[RKClient clientWithBaseURLString:#"http://MyWebsite.com"];
NSDictionary* params = [NSDictionary dictionaryWithObjectsAndKeys:
self.linkField.text, #"url",
self.linkTitleField.text, #"title",
self.linkSummaryField.text, #"summary",
nil];
RKRequest *request = [[RKClient sharedClient] post:#"/send_link.php" params:params delegate:self];
[request setUserData:#"sendLink"];
}
Question: Which property of cookies should I store to use it for login information and where should I put it in my code?
I solved this issue by some inefficient way. Here is my methodology:
First I try to post to the web service and after posting I parse the returning HTML to see if the posting was successful or not. If posting was successful I give an appropriate message to the user that you post successfully but if it was not successful it could have two reasons: First: there were some error during the post execution Second: the user was not logged in. The way that I recognize the differentiation between fist and second error is just parsing the response HTML.
Here is the code that I used for this methodology (this is for the time that the user wants to change the password)
- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error {
NSRange range = [[error localizedDescription] rangeOfString:#"-1012"];
if (range.length > 0){
//First error occurs here
}
RKLogError(#"Hit error: %#", error);
}
- (IBAction)requestToChangePasswordPressed {
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.labelText = #"Loading";
[RKClient clientWithBaseURLString:#"http://WebServiceDomain.com"];
NSDictionary* params = [NSDictionary dictionaryWithObjectsAndKeys:
self.oldPasswordField.text, #"oldPassword",
self.passwordNew.text, #"newPassword",

It shows me the fail popup of Incorrect username and password
I have checked through nslog that username and password are going correct.
what could be wrong?
It looks like the version of MGTwitterEngine you're using is trying to use basic auth. That was switched off in Twitter in favour of OAuth. Get a newer version of MGTwitterEngine (or a fork that supports OAuth).
I have integrated xmpp in my app and able to list all the users in a table view, but I only want to display the online users and then want to implement the feature to send and recieve messages to my online friends...
Please suggest me some helpful code...
Here is my code, executed after facebook login.

I don't know the actual flow of the xmpp framework for showing users online and to implement chat feature...
i have the following delegate methods as well..
- (void)xmppStreamDidSecure:(XMPPStreamFacebook *)sender
{
NSLog(#"---------- xmppStreamDidSecure: ----------");
}
- (void)xmppStreamDidConnect:(XMPPStreamFacebook *)sender
{
NSLog(#"---------- xmppStreamDidConnect: ----------");
isOpen = YES;
NSError *error = nil;
if (![self.xmppStreamFB authenticateWithAppId:_APP_ID accessToken:self.accessToken error:&error])
{
NSLog(#"Error authenticating: %#", error);
}
else {
NSLog(#"NO Error authenticating:");
/*
ChatViewController *cvc = [[ChatViewController alloc] init];
[self.view addSubview:cvc.view];*/
}
}
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
NSLog(#"---------- xmppStreamDidAuthenticate: ----------");
[self goOnline];
}
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error
{
NSLog(#"---------- xmppStream:didNotAuthenticate: ----------");
}
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
NSLog(#"---------- xmppStream:didReceiveIQ: ----------");
/*
ChatViewController *cvc = [[ChatViewController alloc] init];
[self.view addSubview:cvc.view];*/
return NO;
}
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
{
NSLog(#"---------- xmppStream:didReceiveMessage: ----------");
}
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
{
NSLog(#"---------- xmppStream:didReceivePresence: ----------");
}
- (void)xmppStream:(XMPPStream *)sender didReceiveError:(id)error
{
NSLog(#"---------- xmppStream:didReceiveError: ----------");
}
- (void)xmppStreamDidDisconnect:(XMPPStream *)sender
{
NSLog(#"---------- xmppStreamDidDisconnect: ----------");
if (!isOpen)
{
NSLog(#"Unable to connect to server. Check xmppStream.hostName");
}
}
And the two methods for online and offline user presence, but don't know how to modify them for my task:
- (void)goOnline
{
NSXMLElement *presence = [NSXMLElement elementWithName:#"presence"];
[[self xmppStream] sendElement:presence];
}
- (void)goOffline
{
NSXMLElement *presence = [NSXMLElement elementWithName:#"presence"];
[presence addAttributeWithName:#"type" stringValue:#"unavailable"];
[[self xmppStream] sendElement:presence];
}
finally after lots of efforts i found out how to show online/offline/away users.
i'm going to tell you step by step how i did it, so that i can be useful for the less experienced users too..
Step 1- on click of chat button i'm calling the following method-
-(void) chatFacebook
{
if (appDelegate.facebook == nil)
{
appDelegate.facebook = [[[Facebook alloc] initWithAppId:_APP_ID] autorelease];
}
if (!accessToken)
{
[appDelegate.facebook authorize:[XMPPStreamFacebook permissions] delegate:self appAuth:NO safariAuth:NO];
}
else
{
[self fbDidLogin];
}
}
step 2- Now its time for login dialog delegate methods to come in , if the login is successfull the fbDidLogin is called, here are the delegate methods you should include-
#pragma mark FBLoginDialogDelegate
/**
* Called when the user successfully logged in.
*/
- (void)fbDidLogin
{
NSLog(#"logged in.....................");
[appDelegate.facebook requestWithGraphPath:#"me" andDelegate:self];
DDLogVerbose(#"%s accessToken: %# expirationDate: %#",__PRETTY_FUNCTION__,appDelegate.facebook.accessToken,appDelegate.facebook.expirationDate);
self.accessToken = appDelegate.facebook.accessToken;
if (xmppStream) {
[xmppStream release];
xmppStream = nil;
}
xmppStream = [[XMPPStreamFacebook alloc] init];
xmpReconnect = [[XMPPReconnect alloc] initWithStream:xmppStream];
if (xmppRosterStorage) {
[xmppRosterStorage release];
xmppRosterStorage = nil;
}
xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];
if (xmppRoster) {
[xmppRoster release];
xmppRoster = nil;
}
xmppRoster = [[XMPPRoster alloc] initWithStream:xmppStream rosterStorage:xmppRosterStorage];
[xmppStream addDelegate:self];
[xmppRoster addDelegate:self];
[xmppRoster setAutoRoster:YES];
xmppStream.myJID = [XMPPJID jidWithString:[NSString stringWithFormat:#"%##chat.facebook.com", uid]];
// You may need to alter these settings depending on the server you're connecting to
allowSelfSignedCertificates = NO;
allowSSLHostNameMismatch = YES;
// Uncomment me when the proper information has been entered above.
NSError *error = nil;
if (![xmppStream connect:&error])
NSLog(#"Error connecting: %#", error);
if(!tableView)
{
tableView = [[UITableView alloc]initWithFrame:CGRectMake(0,0, 480, 320) style:UITableViewStylePlain];
}
[tableView setFrame:CGRectMake(0,0, 480, 320)];
[tableView setTag:2];
[tableView setDelegate:self];
[tableView setDataSource:self];
[tableView setHidden:NO];
[tableView setBackgroundColor:[UIColor clearColor]];
[tableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
[tableView setAlpha:1.0];
[self.view addSubview:tableView];
[self.tableView reloadData];
[self showTopBar];
}
/**
* Called when the user dismissed the dialog without logging in.
*/
- (void)fbDidNotLogin:(BOOL)cancelled
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Canceled" message:#"Login cancled" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
[alert release];
}
/**
* Called when the user logged out.
*/
- (void)fbDidLogout
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Logged out" message:#"Logged out" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
[alert release];
}
Step 3- The second line of the fbDidLogin method calls the FBRequestDelegate methods so you should include this protocol in your .h class, to get the uid of the user(which is logged in , means the current user) you need to implement the following methods-
pragma mark
pragma mark FBRequestDelegate
- (void)request:(FBRequest*)request didFailWithError:(NSError*)error{
DDLogError(#"%s %#",__PRETTY_FUNCTION__,error);
//[appDelegate.facebook logout:self];
}
/**
* Called when a request returns and its response has been parsed into an object.
* The resulting object may be a dictionary, an array, a string, or a number, depending
* on thee format of the API response.
*/
- (void)request:(FBRequest*)request didLoad:(id)result {
DDLogVerbose(#"%s............DDLOG................... %#",__PRETTY_FUNCTION__,result);
NSLog(#" Result>>>>-------%#", result);
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithDictionary:(NSMutableDictionary *)result];
uid = [dict objectForKey:#"id"];
NSLog(#"iddddddddddddd---%#", uid);
}
Step 4- Now comes the table view DataSource and Delegate methods, you need to implement these, here are the methods-
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView1
{
return [[[self fetchedResultsController] sections] count];
// need to implement NSFetchedResultsControllerDelegate
}
- (NSString *)tableView:(UITableView *)sender titleForHeaderInSection:(NSInteger)sectionIndex
{
NSArray *sections = [[self fetchedResultsController] sections];
if (sectionIndex < [sections count])
{
id <NSFetchedResultsSectionInfo> sectionInfo = [sections objectAtIndex:sectionIndex];
int section = [sectionInfo.name intValue];
switch (section)
{
case 0 : return #"Available";
case 1 : return #"Away";
default : return #"Offline";
}
}
}
return #"";
}
- (NSInteger)tableView:(UITableView *)tableView1 numberOfRowsInSection:(NSInteger)sectionIndex
{
NSArray *sections = [[self fetchedResultsController] sections];
if (sectionIndex < [sections count])
{
id <NSFetchedResultsSectionInfo> sectionInfo = [sections objectAtIndex:sectionIndex];
return sectionInfo.numberOfObjects;
NSLog(#"section ifnfo ===========%#", sectionInfo);
}
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
[cell setSelectionStyle:UITableViewCellSelectionStyleGray];
user = [[self fetchedResultsController] objectAtIndexPath:indexPath];
cell.textLabel.text = user.displayName;
cell.textLabel.textColor = [UIColor whiteColor];
cell1 = cell;
}
Step 5- Finally you also need to implement NSFetchedResultsController delegate methods , so that you can fill table with the chat users, here are the methods-
- (NSFetchedResultsController *)fetchedResultsController
{
if (fetchedResultsController == nil)
{
NSEntityDescription *entity = [NSEntityDescription entityForName:#"XMPPUserCoreDataStorage"
inManagedObjectContext:[self managedObjectContext]];
NSSortDescriptor *sd1 = [[NSSortDescriptor alloc] initWithKey:#"sectionNum" ascending:YES];
NSSortDescriptor *sd2 = [[NSSortDescriptor alloc] initWithKey:#"displayName" ascending:YES];
NSArray *sortDescriptors = [NSArray arrayWithObjects:sd1, sd2, nil];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
[fetchRequest setEntity:entity];
[fetchRequest setSortDescriptors:sortDescriptors];
[fetchRequest setFetchBatchSize:10];
fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest
managedObjectContext:[self managedObjectContext]
sectionNameKeyPath:#"sectionNum"
cacheName:nil];
[fetchedResultsController setDelegate:self];
[sd1 release];
[sd2 release];
[fetchRequest release];
NSError *error = nil;
if (![fetchedResultsController performFetch:&error])
{
NSLog(#"Error performing fetch: %#", error);
}
}
return fetchedResultsController;
}
- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller
{
[[self tableView] reloadData];
}
Step 6 - Compile and run your code ,user list should appear in table view
if any problems appears, please share , i'm always here to help you .And please dont mind if there are some mistakes while posting this answer, cz i'm posting just for the third time
Thanks.
