I am new one to twitter integration in iOS5.
I need to post photos in twitter coming from services.
I have searched many and also practiced sample tutorials on this.
I am getting only photo URL. I need to post photo.
Can anyone help me regarding this?
Thanks in advance.
First you need to save the images and then you can post saved image to twitter
self.shareImg.image = [UIImage imageNamed:#"Your Saved image"];
if ([[[UIDevice currentDevice] systemVersion] floatValue] > 5.0) {
// Create the view controller
TWTweetComposeViewController *twitter = [[TWTweetComposeViewController alloc] init];
NSString *str = [NSString stringWithFormat:#"I created this photo http://%#", iTune];
// Optional: set an image, url and initial text
[twitter addImage:self.shareImg.image];
[twitter setInitialText:[NSString stringWithFormat:#"I created this photo using USC Project Trojan App:http://uslofphoto.com. Download http://%#", iTune]];
// Show the controller
[self presentModalViewController:twitter animated:YES];
// Called when the tweet dialog has been closed
twitter.completionHandler = ^(TWTweetComposeViewControllerResult result)
{
NSString *title = #"Tweet Status";
NSString *msg;
if (result == TWTweetComposeViewControllerResultCancelled)
msg = #"Tweet compostion was canceled.";
else if (result == TWTweetComposeViewControllerResultDone)
msg = #"Tweet composition completed.";
// Show alert to see how things went...
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil];
[alertView show];
// Dismiss the controller
[self dismissModalViewControllerAnimated:YES];
};
}

As twitter framework is added in ios5.0 I am using its class TWTweetComposeViewController
if([TWTweetComposeViewController canSendTweet])
{
NSLog(#"can send tweet");
}
else{
NSString *message = #"The application cannot send a tweet at the moment. This is because it cannot reach Twitter or you don't have a Twitter account associated with this device.";
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Oops" message:message delegate:nil cancelButtonTitle:#"Dismiss" otherButtonTitles:nil];
[alertView show];
}
On this step I need to show user the login page of twitter.For that I am confused if i should redirect user to settings to login to user?
And if yes this code is not working
NSURL *twitterURL = [NSURL URLWithString:#"prefs:root=TWITTER"];
[[UIApplication sharedApplication] openURL:twitterURL];
Also I have read some where that this will not work in ios6. So what should i do to just make user login for a moment and not send tweet directly. Right now i just want to make user login.
I also refer to this question It is working with ios6 well but in that case how do i handle for ios5.1 ?
Any help will be appreciated....
I figured it out with below conditional coding..
I got only this way. If anyone have any other way please suggest me.
if (SYSTEM_VERSION_LESS_THAN(#"6.0")) {
if(SYSTEM_VERSION_EQUAL_TO(#"5.0"))
{
NSURL *twitterURL = [NSURL URLWithString:#"prefs:root=TWITTER"];
[[UIApplication sharedApplication] openURL:twitterURL];
}else{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(#"No_Tw", nil) message:NSLocalizedString(#"No_TW_Ac", nil) delegate:nil cancelButtonTitle:NSLocalizedString(#"Button_Ok", nil) otherButtonTitles:nil, nil];
[alertView show];
}
}
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"6.0")) {
SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
tweetSheet.view.hidden=TRUE;
[self presentViewController:tweetSheet animated:NO completion:^{
[tweetSheet.view endEditing:YES];
}];
}
If iOS is 5.0 then it will redirect to login of Twitter otherwise it will show alert to user to go to settings and do login. And for for iOS 6.0 and larger SLComposeViewController is working fine.
I am very new to iOS development.I am making an application in which i required to integrate twitter and Facebook for wall posting.
I have done all the required coding for this and on simulator it is working fine but not on device.
one more question as the coding for Facebook integration i have copied it from other "demo" application.So what else we need to change in it to make it for my own application.Because when i see my update done by my app on Facebook wall, "demo" app name comes there with the post.
Please guide me !!Thanking you in Advance!!
Facebook
It seems you have jumped to coding part before reading the documentation. Before integrating facebook sdk and writing your code, you need create a new app section in facebook developer console, get an Facebook app id. You need to use that app id in your project, not the app id shipped with facebook demo application.
Documentation explains the process fully, no need to rewrite it here. Make sure you read it to the end.
Twitter
I am not sure if you are having problem in twitter also (question is unclear on that). If yes, you should tell how you are connecting to twitter. But generally, from the tone of your questions, it seems you haven't read the documentation, on creating an app section in respective developer console, and getting app id.
I don't know how much integration you need or if your willing to require iOS 6 but in iOS 6 it is SO MUCH easier to integrate Facebook and Twitter.
This is all the code:
In the header file:
#import "Social/Social.h"
In the main file:
//Twitter
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
if (result == SLComposeViewControllerResultCancelled) {
NSLog(#"Cancelled");
} else {
NSLog(#"Done!");
}
[controller dismissViewControllerAnimated:YES completion:Nil];
};
controller.completionHandler = myBlock;
[controller setInitialText:#"Status Text"];
[self presentViewController:controller animated:YES completion:Nil];
} else {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Sorry" message:#"You can't send a tweet right now. You must be online and signed into at least one Twitter account." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
//Facebook
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
if (result == SLComposeViewControllerResultCancelled) {
NSLog(#"Cancelled");
} else {
NSLog(#"Done!");
}
[controller dismissViewControllerAnimated:YES completion:Nil];
};
controller.completionHandler = myBlock;
[controller setInitialText:#""];
[self presentViewController:controller animated:YES completion:Nil];
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Facebook Error" message:#"Either you are not logged into Facebook or your Facebook username and password are incorrect." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
You Can use Share kit framework, http://getsharekit.com
As per integrating twitter in your application.Try this code
at self.fullimage write any url of image.
Call buildTweetSheet method to post to twitter.
import Twitter.framework
import
#property(nonatomic,strong) TWTweetComposeViewController *_tweetSheet;
#synthesize _tweetSheet;
-(void)buildTweetSheet
{
NSLog(#"buildTweetSheet");
_tweetSheet = [[TWTweetComposeViewController alloc] init];
UIImage *eimage=UIImage *eimage=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:self.fullimage]]];
[_tweetSheet setInitialText:#""];
[_tweetSheet addImage:eimage];
[_tweetSheet setInitialText:#""];
[self presentModalViewController:_tweetSheet animated:YES];
TWTweetComposeViewControllerCompletionHandler completionHandler = ^(TWTweetComposeViewControllerResult result)
{
if(result == TWTweetComposeViewControllerResultDone) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Done" message:#"Image Posted Successfully" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Failed" message:#"Image Posted Failed" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
}
[self dismissModalViewControllerAnimated:YES];
};
[_tweetSheet setCompletionHandler:completionHandler];
}
I am using the following code to post something on Facebook.
- (IBAction)post:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
mySocialComposer = [[SLComposeViewController alloc]init];
mySocialComposer = [SLComposeViewController
composeViewControllerForServiceType:SLServiceTypeFacebook];
[mySocialComposer setInitialText:#"Hellooooooo World"];
[mySocialComposer addImage:[UIImage imageNamed:#"image.jpg"]];
[self presentViewController:mySocialComposer animated:YES completion:nil];
[mySocialComposer setCompletionHandler:^(SLComposeViewControllerResult result){
NSString *outout = [[NSString alloc] init];
switch (result) {
case SLComposeViewControllerResultCancelled:
outout = #"Post Cancled";
break;
case SLComposeViewControllerResultDone:
outout = #"Post Successfull";
default:
break;
}
UIAlertView *myalertView = [[UIAlertView alloc]initWithTitle:#"FaceBook"
message:outout delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[myalertView show];
}];
}
}
I am using the above method to post on Facebook from iOS app.If I do post including an Image and some text it successfully post ed on Facebook. But when I try to post on Facebook without the image just text for that purpose i comment out the following line.
[mySocialComposer addImage:[UIImage imageNamed:#"image.jpg"]];
And while doing that i got an error alert that This post cannot be sent because connection to Facebook lost. Is there any way that i can post on Facebook without image . Thanks in advance.
You can just set the add image to nil. You should be able to post fine.
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
SLComposeViewController* mySocialComposer = [SLComposeViewController
composeViewControllerForServiceType:SLServiceTypeFacebook];
[mySocialComposer setInitialText:#"Hellooooooo World"];
[mySocialComposer addImage:nil];
[self presentViewController:mySocialComposer animated:YES completion:nil];
[mySocialComposer setCompletionHandler:^(SLComposeViewControllerResult result){
NSString *outout = [[NSString alloc] init];
switch (result) {
case SLComposeViewControllerResultCancelled:
outout = #"Post Canceled";
break;
case SLComposeViewControllerResultDone:
outout = #"Post Successfull";
default:
break;
}
As per Apple's official documentation on SLComposeViewController you will see that it says
Return Value
Returns a Boolean value indicating whether the text was successfully set.
Discussion
This method returns NO if text does not fit in the currently available character space or if the view controller has already been presented to the user (and therefore cannot be changed). Character limits are dependent on the target service and are documented by the service provider. For links to documentation for the supported services, see “Table 1Social Services Individual Documentation Sites” in SLRequest Class Reference.
So if this controller has already been shown it is not going to work. Try a different text and see again.
Can you remove
mySocialComposer = [[SLComposeViewController alloc]init];
You are not supposed to do that.
[mySocialComposer setInitialText:#"Hellooooooo World"];
[mySocialComposer addImage:[UIImage imageNamed:#"image.jpg"]];
[self presentViewController:mySocialComposer animated:YES completion:nil];
Put these lines of code after you set your completion handler.
Also remove the UIAlertView from there and put it inside the completion handler for error case.

iOS 5 Attach photo to Twitter with Twitter API
Some Twitter clients have a photo tweet feature. Does the iOS 5 Twitter API also include a way to tweet a photo?
Read this : TWTweetComposeViewController Class Reference
and the - addImage property
Yes of course
if ([[[UIDevice currentDevice] systemVersion] floatValue] > 5.0) {
// Create the view controller
TWTweetComposeViewController *twitter = [[TWTweetComposeViewController alloc] init];
// Optional: set an image, url and initial text
[twitter addImage:[UIImage imageName:#"YourImage.png"]];
[twitter setInitialText:#"I created this photo Download http://www.twetter.com"];
// Show the controller
[self presentModalViewController:twitter animated:YES];
// Called when the tweet dialog has been closed
twitter.completionHandler = ^(TWTweetComposeViewControllerResult result)
{
NSString *title = #"Tweet Status";
NSString *msg;
if (result == TWTweetComposeViewControllerResultCancelled)
msg = #"Tweet compostion was canceled.";
else if (result == TWTweetComposeViewControllerResultDone)
msg = #"Tweet composition completed.";
// Show alert to see how things went...
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil];
[alertView show];
// Dismiss the controller
[self dismissModalViewControllerAnimated:YES];
};
}
There is need to use TWTweetComposeViewController Class Reference
Refer ios-5-attach-photo-to-twitter-with-twitter-api link for code.
I'm planning updates for an enterprise app with ad-hoc distribution.
For updates, Apple recommends having the user visit an HTML page and tap on a link:
href="itms-services://?action=download-manifest&url=http://example.com/
manifest.plist"
See http://help.apple.com/iosdeployment-apps/#app43ad871e
I don't want to do this. I want the app to programmatically check for updates on launch and alert the user with a UIAlertView that an update is available.
Here's what I have so far in application didFinishLaunching. The complicated plist parsing comes from the structure of an example plist found here: http://help.apple.com/iosdeployment-apps/#app43ad78b3
NSLog(#"checking for update");
NSData *plistData = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://example.com/MyApp.plist"]];
if (plistData) {
NSLog(#"finished checking for update");
NSError *error;
NSPropertyListFormat format;
NSDictionary *plist = [NSPropertyListSerialization propertyListWithData:plistData options:NSPropertyListImmutable format:&format error:&error];
if (plist) {
NSArray *items = [plist valueForKey:#"items"];
NSDictionary *dictionary;
if ([items count] > 0) {
dictionary = [items objectAtIndex:0];
}
NSDictionary *metaData = [dictionary objectForKey:#"metadata"];
float currentVersion = [[[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleVersion"] floatValue];
float newVersion = [[metaData objectForKey:#"bundle-version"] floatValue];
NSLog(#"newVersion: %f, currentVersion: %f", newVersion, currentVersion);
if (newVersion > currentVersion) {
NSLog(#"A new update is available");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Update available" message:#"A new update is available." delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"UPDATE", nil];
[alert show];
}
}
}
Then I have my UIAlertView delegate method:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 1) {
NSLog(#"downloading full update");
UIWebView *webView = [[UIWebView alloc] init];
[webView loadRequest:[[NSURLRequest alloc] initWithURL:[NSURL URLWithString:#"itms-services://?action=download-manifest&url=http://example.com/MyApp.plist"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0]];
}
}
A few things:
I know [alert show] shouldn't be called in application didFinish, but I'll change it later.
I don't know how quickly plistData will be downloaded and how this download affects the app.
More importantly, my alert view delegate method doesn't work, and the update doesn't download. Even when I introduce webView with #property (nonatomic, strong) UIWebView *webView, the method doesn't do anything.
I think Dropbox has the MIME configured properly because I can download the .ipa through google Chrome.
So what I really need is a way using NSURLConnection (NSURLRequest etc.) to replicate the act of a user tapping on an HTML href. After that I think the full update will occur.
You can open a URL automatically using
[[UIApplication sharedApplication] openURL:...];
I don't know if it works for itms-services: urls, but it works for other bespoke URL schemes like tel:, fb: etc. so it should do unless Apple have specifically blocked it.
