Twit with TwitterAgent : One line code, auto tineURL

[AmanApps]

Hello all,

Perhaps you have seen my post on FacebookAgent class which simplifies facebook integration into your iPhone app.

Now, I would like the share my TwitterAgent class with you.
Using this class you can integrate twitter into your app in a single line of code!

[[TwitterAgent defaultAgent] twit ];

[[TwitterAgent defaultAgent] twit:@"Search with google!" ];

[[TwitterAgent defaultAgent] twit:@"Search with google!" withLink:@"http://www.google.com" makeTiny:NO];

[[TwitterAgent defaultAgent] twit:@"Search with google!" withLink:@"http://www.google.com" makeTiny:YES];

Read more and Download the code from here.

Some screenshots:







Any feedback and suggestion is highly appreciated.

i'll definitely give it a try!

Nice work again Aman; I notice the custom login...does this not go through oAuth?

[AmanApps]

@dissonance: let me know if you have any suggestion

@scotopia, hey, Thanks! nope, its not open auth.
I was looking for you, could you manage time on using open auth with iphone? I was totally lost in the open auth section on twitter site...

[scotopia]

Yeah I got oAuth working with regular twitter updates; unfortunately image services like twitpic, yfrog etc don't do oAuth with their API so i've had to fall back on basic auth for those. Basically I just modified ben gottlieb's engine here: bengottlieb's Twitter-OAuth-iPhone at master - GitHub

[alon7]

Thank you !!!
I really needed this!

can you post a sample app that show how to use it?

It doesn't work for me.

Thanks again.

@alon7:
When you add the folders to your project, you have to select 'copy' instead of reference. It worked with me anyway.. here is sample project. What I have done here:
1. Created a new project.
2. from xcode added the TwitterAgent and the BusyAgent folders to the project. Selected copy.
3. added a button to the view.
4. added a touch event inside handler for the button.
5. in the handler code, i used the twitter agent.

btw, don't forget to import TwitterAgent.h where you want to use this.

Let me know if still any prob.


@scotopia: cool man! Thanks for sharing the link

[alon7]

Thanks, worked for me.

[alon7]

Another problem popped up.

I have a tableview and a didSelectRowAtIndexPath method.

When I'm pressing the cell its shows a alertview the asks cancel or facebook.

If I press facebook, nothing happens.
(Of course it have the facebook code: [fbAgent setStatus:@"status from iPhone demo"]; )

Where is the problem?

I tried to make a new view and put it in the viewDidLoad method and it didn't work either.

Seems like it's only working with UIButton.

Any suggestions?

Thanks.

[AmanApps]

hi Alon7,
Sorry man, I also faced the same problem for some reason it doesn't work on viewDidLoad..

If you find out any solution, please share. I will also look into it. Currently working on creating another tool.
Thanks.

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.

here is the another link from where you can download twitter application.Not developed by me but I can help you if you want.

Wow, I'm getting better... I found a bug, and I fixed it! (I love this wrapper class, by the way.)

In line 401 of TwitterAgent.m it should read:

NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"http://tinyurl.com/api-create.php?url=%@",link]];

The percent sign was missing, and that broke it. You'd get Tiny URLs, but they didn't go anywhere, because it was generating TinyURLs for the link "@" instead of what was intended.

Now, could someone find that one other bug in the Facebook agent for me, that was the limit of my brain power!

[AmanApps]

Thanks for the fix

[[TwitterAgent defaultAgent] twit:@"%@", barObj.barName];

Too many arguments to function twit.
Am i missing something here? No doubt I am! Thank for help if you can

It is good that we can tweet with the twitter agent, I will appreciate if you twit or facebook share the blog link so other also might get help...

I really like your popup dialogs, similar to BiteSMS txt input dialog. I may be 'liberating' that code.


I'd suggest implementing xAuth authentication, which in my opinion is better that oAuth as you can control user/pass input and token management yourself.

Like OAuth xAuth uses a one-off token exchange when the user authorises you app at first use.

xAuth requires you to contact twitter (via email) and perform registration of your app. Twitter posts then say 'from myApp'. Twitter took around a day to respond to my request and authorise my app for xAuth. Until authorised you just get a network error (401 ?) if you try and connect using xAuth.


There is a xAuth framework written and published under MIT license

blogg : Aral Balkan xAuthTwitterEngine library and demo
code : aral's XAuthTwitterEngine at master - GitHub

This framework is itself made up of MGTwitter etc, so I'm sure the author would have no issues with incorporating the authentication section into your own framework - assuming the code was published under the same open license.

I implemented twitter using this xAuth framework and must say it works really well. I used keychain to store the exchanged token, and provided a way to log out which simply deletes the token from the keychain - next access see's there's no token and requests login/authentication again.

@funkyspider

Thanks A LOT for the links! I will integrate oAuth asap since its the ultimate way!

[funkyspider]

xAuth - you have to register app with twitter and request xAuth access (via email - link on that blogg page) and control your own login view.

OAuth - handles the login for you if the app hasn't been authorised. You do not have to register your app with twitter via Email. This is the OAuth login page which is automatically displayed.

An oAuth framework also exists under MIT license.
bengottlieb's Twitter-OAuth-iPhone at master - GitHub

I added similar text to my xAuth login form -

"app requesting access to read and post to twitter. You may revoke access at any time by visiting your settings page in twitter"


To store the xAuth exchange token in the phones keychain is a pain, but again there is a framework which simplifies it massively.
Sci-Fi Hi-Fi: Weblog: Simple iPhone Keychain Code
security at master from ldandersen's scifihifi-iphone - GitHub

+ (NSString *) getPasswordForUsername: (NSString *) username andServiceName: (NSString *) serviceName error: (NSError **) error;
+ (void) storeUsername: (NSString *) username andPassword: (NSString *) password forServiceName: (NSString *) serviceName updateExisting: (BOOL) updateExisting error: (NSError **) error;
+ (void) deleteItemForUsername: (NSString *) username andServiceName: (NSString *) serviceName error: (NSError **) error;

Using xAuth/oAuth all you actually store is the single token value which is given to you when the user authorises.

As you are only storing a token value which has been returned from you can hard code the username as 'twituser', the serviceName as 'twitter' etc when using the getPasswordForUsername/ storeUsername / deleteItemForUsername methods. The token is then just stored as the password.

[MozyMac]

OMG DUDE, You are a live saver, I'm trying your facebook code as well, hope it's as awesome and easy as this!

[MozyMac]

any chance that you could update the code to add remember me (password and username) feature ?

Thank you.

[AmanApps]

@mozymac: It was not saved due to a bug. Just before fixed it and committed.
Please check out from the google code or from my blog.

thanks

@funkyspider: cool, just one prob is that users have to leave the application to let safari open. thanks.

[kumar74]

can you upload or email me your code for Twitter using Xauth? It will really be a great help. Thanks in Advance.

Hi it all works fine for me apart for when I want to pass in my own values as below - I get the error message 'too many arguments to function twit' - does anyone know how to sort this - thanks

-(IBAction) response1 {
NSInteger row = [singlePicker selectedRowInComponent:0];
NSString *selected = [pickerData objectAtIndex:row];

[[TwitterAgent defaultAgent] twit:@"%@!", selected];
}
