Question

我想将Facebook和Twitter帐户与我的iOS应用程序连接起来。我正在寻找检查帐户是否在设置中的代码。如果它在那里需要使用相同的帐户登录，如果不是，则要求用户在设置中添加帐户。

我尝试了几件事，但实际上没有用。如果有人需要我的代码，请告诉我，我会将其发布在pastebin上。

Answer 1

在项目中添加Twitter和社交框架，并导入类文件，如

#import <Social/Social.h> #import <Twitter/Twitter.h>

For Facebook

if（[SLComposeViewController isAvailableForServiceType：SLServiceTypeFacebook]）{

    SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

    NSData *aImgdata=[[NSUserDefaults standardUserDefaults]objectForKey:@"EditImage"];
    if (aImgdata) {
        UIImage *aImage=[UIImage imageWithData:aImgdata];
        [controller addImage:aImage];
    }

    controller.completionHandler = ^(SLComposeViewControllerResult result) {
        if(result == SLComposeViewControllerResultDone) {

        }
        [self dismissViewControllerAnimated:YES completion:nil];

    };
    [self presentViewController:controller animated:YES completion:Nil];
}
else
{

     [self ShowAlertView: @"You can't share on facebook right now, make sure your device has an internet connection and you have at least one Facebook account setup"];

}

For Twitter

if（[TWTweetComposeViewController canSendTweet]）{

        {

            TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];

            NSData *aImgdata=[[NSUserDefaults standardUserDefaults]objectForKey:@"EditImage"];
            if (aImgdata) {
                UIImage *aImage=[UIImage imageWithData:aImgdata];
                [tweetViewController addImage:aImage];
            }

            tweetViewController.completionHandler = ^(TWTweetComposeViewControllerResult result) {
                if(result == TWTweetComposeViewControllerResultDone) {

                    [self ShowAlertView: @"Tweet Has been Shared"];

                }
                [[AppDelegate sharedInstance]showActivity:NO];
                [self dismissViewControllerAnimated:YES completion:nil];
            };

            [self presentViewController:tweetViewController animated:YES completion:nil];

        }

    } else {

        [self ShowAlertView: @"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"];
    }

为您的项目添加社交框架并在您的课程中导入

#import <Social/Social.h>

对于Facebook

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

    [controller addImage:UIImage];
controller.completionHandler = ^(SLComposeViewControllerResult result) {
    if(result == SLComposeViewControllerResultDone) {

    }
    [self dismissViewControllerAnimated:YES completion:nil];

};
[self presentViewController:controller animated:YES completion:Nil];
}
else
{

 //Show Alert: No Facebook Account in Settings Page

}

对于Twitter

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {

SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];

    [controller addUrl:NSURL];
controller.completionHandler = ^(SLComposeViewControllerResult result) {
    if(result == SLComposeViewControllerResultDone) {

    }
    [self dismissViewControllerAnimated:YES completion:nil];

};
[self presentViewController:controller animated:YES completion:Nil];
}
else
{

 //Show Alert: No Twitter Account in Settings Page

}

Answer 3

要检查您是否可以与Facebook或Twitter分享，请使用：
[SLComposeViewController isAvailableForServiceType:serviceType]
其中serviceType可以是任何SLServiceTypes，例如SLServiceTypeFacebook和SLServiceTypeTwitter

这基本上将检查他们是否在其设置中本机连接了这些服务。我认为您不能要求用户在其设置中添加它。大多数情况下，如果某个特定的共享选项在UIActionSheet上不可用，则不会显示。

我的猜测是您可以使用SLComposeViewController检查已连接的帐户，如果没有连接，请使用相应的SDK将其帐户与您的iOS应用相关联。
