CAN U PLEASE SUGGEST ME HOW TO INTEGRATE TWITTER TO MY APP....

Is it free? I mean, can I use it in my app?

yea all code available in this site is free.

But most probably it won't work any more and at present I am not updating any code... busy in other projects at office :(

Tinyurl have a problem.
When i publish, the link tinyurl always are the same :s

Great stuff, Aman. You really made FB & Twitter integration easy.

That said, I ran a "Build and Analyze" and you've got a few memory leaks in your code. Any plans to address those in the future?

Awesome Aman Vai, very helpful.

Awesome tutorial... Really it helped me a lot.. thanks for giving us this wonderful tutorial. One thing i found is it is not handling the error if the user entered password or log in name is wrong?

Hello,

I want to put instead of the link inside the "withLink" I want to put a string. How can I do that?

Thank you.

new issue, it seems that no matter what username and password are entered, i still login and can post. Even if the username does not exist or the password is wrong I still get to the post screen and can post.

Same here. I changed my username, but it still show the old name and post on Twitter.

I solved this problem if you look below by simply parsing the data received back by twitter. If the data had the word "errors" in it, I call connectionDidFailWithError with isAuthFailed = YES so that I get a UIAlert that the username/password were incorrect. if the data had the word "user" in it, I let the user login. This is a basic explanation of what I did, although I have now switched over to using OAuth for Twitter since this basic http auth won't work as of June (forget the day).

thanks Uber

Can you upload your code with Oath here pls? It will be great help to many people.

do a google search for "An example iPhone Twitter app with OAuth authentication" and usually the first item is where I got the code from. the blog is by a guy named jaanus, which it should say at the top of the page.

just checked it... you are right.. but no idea why its happening.. earlier I found it working.... i am totally confused.. digged for some time but no help.... please do share if you found what's happening or why not happening.
thanks.

I used this to trace what was being recieved:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {

NSString* strData = [[[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSASCIIStringEncoding] autorelease];
NSLog(@"Received data: %@", strData ) ;
return ;
}

It prints <error code="32">Could not authenticate you.</error>, so twitter does recognize the invalid username/password but your code does not seem to catch this. I'm still a newbie so I'm not sure how to code in something to catch this error from twitter.

fixed the problem in my code, added in some xml parsing to process an error, posting code in a sec...

I added this to the ".h" file:

NSMutableData* receivedData;

The new methods in the ".m" file are:

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[receivedData setLength:0];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[receivedData appendData:data];

NSXMLParser* parser = [[NSXMLParser alloc] initWithData:data];
[parser setDelegate:self];
[parser parse];

return;
}

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ([elementName isEqualToString:@"errors"])
{
authenticated = NO;
[parser abortParsing];
}

if ([elementName isEqualToString:@"user"])
{
authenticated = YES;
[parser abortParsing];
}
}

Modified methods in the ".m" file are:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[loading1 stopAnimating];
[loading2 stopAnimating];

if(authenticated == NO)
{
isAuthFailed = YES;
NSError* error = [NSError errorWithDomain:NSURLErrorDomain code:1 userInfo:nil];
[self connection:connection didFailWithError:error];
}

if(authenticated == YES)
{
isAuthFailed = NO;

[connection release];
[receivedData release];

if(isLogged)
{
UIAlertView* aler = [[UIAlertView alloc] initWithTitle:@"Twitter" message:@"Tweet Posted!" delegate:nil cancelButtonTitle:@"Close" otherButtonTitles:nil];
[aler show];
[aler release];

[self login];
}

else
{
twitterWindow.hidden = YES;
twitterWindow2.hidden = NO;
isLogged = YES;
[[NSNotificationCenter defaultCenter] postNotificationName:@"notifyTwitterLoggedIn" object:nil userInfo:nil];
}
}
}


Also, "authenticated" is just a simple BOOL I added to the ".m" file.

Oh btw, I changed it so my twitter appears through windows instead of view alerts, if anyone wants the code for that (it's easy to do really) gimme your email and i'll send it over :-)
Guess I should look into OAuth now since basic http auth for Twitter won't work come June...

EDIT: forgot, in "OnLogin" you want to make an else statement for "if(!theConnection)" which says:
"receivedData = [[NSMutableData data] retain];"
Do the same thing for "OnSend"

Hi Aman, first of all, this is a great help. Thanks.

Just 1 error i found, when i run the app with performance tool, i find 1 error which say "xagents_twitter_conifg_file.plist" not found. TweeterAgent.m has reference to this file. pls. advise.

hey Kumar,
thanks for using and reporting this issue :)

that was a typo which was fixed in the latest code.

in twitteragent.m, you find a define of XAGENT_TWITTER_CONFIG_FILE...

update that line with this:
#define XAGENTS_TWITTER_CONFIG_FILE DOC_PATH(@"xagents_twitter_conifg_file.plist")

hope that solves.

hi Aman,

First of all, it is great help, thanks.

When i run the program with performance tool, i get the error that "xagents_twitter_conifg_file.plist file not found. The file TwitterAgent.m refer to this plist file. pls. advise.

Hi Aman, excellent code man! Thanks very much for sharing :)
I have one problem though - I could not find in the code what's the license of this libraries? How does it go if I want to use the TwitterAgent in a commercial app ?

Thanks, Marin

Whatever license suits you best :D

You're awesome :) Will post an article about the Twitter agent on my site when I get 10 minutes

I will really appreciate that... you have a cool blog!

does this use basic http authentication?

yea

Basic Authentication is going not going to be supported as of June 30, 2010. Are you planning to start using OAuth in twitter agent?

When you use landscape mode, and when you click into the textview to edit message, then the keyboard will pop up and will cover the "send"button. However, there is no way to dismiss it after finishing edit. I tried to figure that out. And you may have a try.
In the following function:
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{
const char* str = [text UTF8String];

int s = str[0];
if(s!=0){

if((range.location + range.length) > maxCharLength){
return NO;
}
else{
int left = 139 - ([sharedLink length] + [textView.text length]);
lblCharLeft.text= [NSString stringWithFormat:@"%d",left];
if([text isEqualToString:@"\n"]){

[textView resignFirstResponder];
return FALSE;

}
else {
return YES;
}
}
}

int left = 139 - ([sharedLink length] + [textView.text length]);
lblCharLeft.text= [NSString stringWithFormat:@"%d",left];
return YES;
}

You might also want to allow the backspace character:

if (range.length == 1) return YES;

thanks for the fix :)
plz check http://code.google.com/p/iphone-facebook-twitte...

This is great piece of code. When I integrate it in my App, the user selects "post to twitter", I call the twit:withLink:makeTiny: method which logs the user in and posts the tweets. Now the users stays logged in. I would like to allow the user to logout also. The user may want to log out of that account and log in to another account for a future tweet. Is there a way to add a Logout button on the "tweet this post" view?

Thanks Vic for using it.

I was thinking the same about logout! I will be adding soon, if you do this in the meantime, I will really appreciate if you share.

Thanks.

Is there anyway to include an image in the tweet? like from a screen shot?

no, not yet

Thanks for the quick reply. Back to the drawing board. But this is a great drop in group of code. Thanks for your hard work.

FacebookAgent and TwitterAgent are very cool,
Is very easy to use, packaged very well.
Thank you for sharing such a good code, so that Facebook and Twitter's programming has become so relaxed and happy.

Very much hope that TwitterAgent can easily upload Image, hope to see even better updates, Thanks again.

thanks leo :)

Wow!
I don't have enough words to thank you for these great agents! You are one of a kind! I really mean it.
Now a tiny question: when the user edits the text field of the tweet, how can he get out of edit mode and turn the keyboard down? the return button didn't work for me (it just jumped to the next line) and there was no "done" button.

Thank you for your generosity, I'm very happy that it came into your help.


yea, u r right, but there is a "send" button on the alert box, need to tap the "send" button when done.

True, but in a landscape environment you can't reach the "send" button cause it is obscured by the keyboard..

oops! I didn't test on landscape mode. Currently I'm fully busy in developing our next game at playdom.... dunno when i can manage time to work on this :( If you find a solve, please share.

Thanks! This is really helpful!
One little possible bug: in makeTiny, url create from stringWithFormat seems miss one percent symbol?

thanks. And big thanx for identifying the bug :)

Hey, Thank you very much!
Can you post a sample for this project? because the
defaultAgent doesn't seems to be in here.

Thanks.

seems answered the same person ( here and there ) :)

A sample project: http://amanpages.com/wordpress/wp-content/uploa...

Another person in iphonedevsdk also faced the same prob.. while adding the TwitterAgent and BusyAgent folders, you have to select copy.

Let me know if there is still any problem.
Thanks :).

This is outstanding, One question. Is there a way you can default the text and not allow the user to change it?

hi Jabroni, thanks :)

At this moment its not possible. It will be there just after a while if you tell me the use case:


1. user taps "share with twitter"
2. logs in.
3. The message will be shown to the user in alert but not in textarea i.e. not-editable. Tapping send button will send, cancel cancels.

or

1. user taps "share with twitter"
2. logs in.
3. No alert, only gray busy overlay. Posts the twit in background?


or

Both?

Thank you for your suggestion. I will integrate it just let me know.

newbie question, is it possible to make it so that the twitter menus are portrait mode through code and if so, how? (program comes though unity so I cannot change the plist settings).

not clear what do wanted to mean... it is in portrait mode... can you elaborate?

if i hold the device horizontally (landscape, home button to the right) the twitter login menu rotates to that orientation. If i hold the device vertically (home button on the bottom) the login menu rotates to that orientation. I want the menu to only be in the vertical orientation and not have it adjust when I turn the device (when horizontal, the keyboard covers up where you are putting your tweet and you cannot see what you are typing). Hope that clarifies what I mean.

.. crystal clear :)

no, not possible. Just tried it. I have rotated the alert view -90 degrees so it appears as it should be on portrait mode right but the keyboard orientation remains landscape...

btw, if you checkout the latest code from google code, you will get a fix.. now while typing twit message if the user presses 'enter' key, keyboard disappears. that may help.

thanks :)

ok, thanks though. the code is great regardless. maybe someday twitter @anywhere will get iphone support so we don't run into this problem but your stuff is an awesome solution in the meantime. thanks a bunch!

yea, twitter should release something like Facebook connect.

Thanks for your comment.

And one more thing Aman!!
I have posted the tweets with user locations. In my code self.myFamilyMap.fLatitude & self.myFamilyMap.fLongitude are the values of latitude and longitude respectively.
my app was using a map to locate the family members , so variable names are depicting map for family :-)
