Open Twitter Setting from ACAccountStore (iOS 5.1 TWITTER) - iphone

Question

in iOS 5.0 i was opening Twitter setting from my app by
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"prefs:root=TWITTER"]];
but , this features is removed in iOS 5.1 , hence i can not able to open twitter setting .
Now i am using
+ (void)makeRequestsWithURL: (NSURL *)url {
// Create an account store object.
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
// Create an account type that ensures Twitter accounts are retrieved.
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[self canTweetStatus];
// Request access from the user to use their Twitter accounts.
[accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) {
if(granted) {
// Get the list of Twitter accounts.
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
// For the sake of brevity, we'll assume there is only one Twitter account present.
// You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
if ([accountsArray count] > 0) {
// Grab the initial Twitter account to tweet from.
ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
// Create a request, which in this example, posts a tweet to the user's timeline.
// This example uses version 1 of the Twitter API.
// This may need to be changed to whichever version is currently appropriate.
TWRequest *postRequest = [[TWRequest alloc] initWithURL:url parameters:nil requestMethod:TWRequestMethodPOST];
// Set the account used to post the tweet.
[postRequest setAccount:twitterAccount];
// Perform the request created above and create a handler block to handle the response.
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
NSString *output = [NSString stringWithFormat:#"HTTP response status: %i", [urlResponse statusCode]];
iOS5Twitter *twitter5 = [[iOS5Twitter alloc] init];
[twitter5 performSelectorOnMainThread:#selector(displayText:) withObject:output waitUntilDone:NO];
[twitter5 release]; }];
}
}
}];
}
for making request, i am able to check wether i am loged in or not by the
if ([TWTweetComposeViewController canSendTweet])
but now i want : if i am not loged in it would be show an alert like shown in image and want to move to the twitter setting . is it possible ? or i have to manually go ti twitter setting ?

Answer 1

It is little tricky , i get by the removing the subviews in *TWTWeetComposeViewController*, so it shows only alert when user is not loged in and by the clicking on setting button , we can open Setting page in my app.
+ (void)setAlertForSettingPage :(id)delegate
{
// Set up the built-in twitter composition view controller.
TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];
// Create the completion handler block.
[tweetViewController setCompletionHandler:^(TWTweetComposeViewControllerResult result) {
[delegate dismissModalViewControllerAnimated:YES];
}];
// Present the tweet composition view controller modally.
[delegate presentModalViewController:tweetViewController animated:YES];
//tweetViewController.view.hidden = YES;
for (UIView *view in tweetViewController.view.subviews){
[view removeFromSuperview];
}
}
here , deleate is your viewcontroller , if you are using this method inside your viewcontroller just use self instead of delegate.

iOS 6 uses SLComposeViewController instead of TWTweetComposeViewController, so now you have to do this if you want it to work on iOS 6 and iOS 5:
UIViewController *tweetComposer;
if([SLComposeViewController class] != nil)
{
tweetComposer = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[(SLComposeViewController *)tweetComposer setCompletionHandler:^(SLComposeViewControllerResult result)
{
// do whatever you want
}];
}
else
{
tweetComposer = [[TWTweetComposeViewController alloc] init];
[(TWTweetComposeViewController *)tweetComposer setCompletionHandler:^(TWTweetComposeViewControllerResult result)
{
// do whatever you want
}];
}
for (UIView *view in [[tweetComposer view] subviews])
[view removeFromSuperview];
[self presentViewController:tweetComposer animated:NO completion:nil];

Building upon Senior's and PJR's answers above, this is what worked for me.
Same as Senior's, except with a dimissViewController in the completion handler. For me this got around the problem that the empty view controller would stick around after I returned to the app from the settings. It would overlay my view controller and make it useless.
Brilliant solution, thanks Senior and PJR.
UIViewController *tweetComposer;
if([SLComposeViewController class] != nil)
{
tweetComposer = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[(SLComposeViewController *)tweetComposer setCompletionHandler:^(SLComposeViewControllerResult result)
{
[self dismissViewControllerAnimated:NO completion:nil];
}];
}
else
{
tweetComposer = [[TWTweetComposeViewController alloc] init];
[(TWTweetComposeViewController *)tweetComposer setCompletionHandler:^(TWTweetComposeViewControllerResult result)
{
[self dismissViewControllerAnimated:NO completion:nil];
}];
}
for (UIView *view in [[tweetComposer view] subviews])
[view removeFromSuperview];
[self presentViewController:tweetComposer animated:NO completion:nil];

To remove the post view,
instead using this code:
for (UIView *view in [[tweetComposer view] subviews])
[view removeFromSuperview];
use this:
tweetComposer.view.alpha = 0;
works both for twitter and facebook.
