問題描述

在 iOS 5.0 中，我通過

in iOS 5.0 i was opening Twitter setting from my app by

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]];

但是，這個功能在 iOS 5.1 中被刪除了，因此我無法打開 twitter 設置.

but , this features is removed in iOS 5.1 , hence i can not able to open twitter setting .

現在我正在使用

 + (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];                }];
        }
    }

}];

}

為了提出請求，我可以通過

for making request, i am able to check wether i am loged in or not by the

if ([TWTweetComposeViewController canSendTweet])

但現在我想要:如果我沒有登錄，它會顯示如圖所示的警報，并希望移動到 twitter 設置.是否可以 ?或者我必須手動進入 ti twitter 設置?

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 ?

推薦答案

這有點棘手，我通過刪除 *TWTWeetComposeViewController* 中的子視圖來獲得，所以它只在用戶不存在時顯示警報登錄并點擊設置按鈕，我們可以在我的應用程序中打開設置頁面.

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];
        }

     } 

這里，deleate 是您的視圖控制器，如果您在視圖控制器中使用此方法，只需使用 self 而不是 delegate.

here , deleate is your viewcontroller , if you are using this method inside your viewcontroller just use self instead of delegate.
