我想将 Facebook 和 Twitter 帐户与我的 iOS 应用程序相关联。我正在寻找检查帐户是否存在于设置中的代码。如果有，则需要使用相同的帐户登录，如果没有，则要求用户在设置中添加帐户。
我尝试了几件事，但真的没有用。如果有人需要我的代码，请告诉我，我会将其发布在 pastebin 上。

在您的项目中添加 Twitter 和社交框架并导入您的类文件中，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"];
}

将社交框架添加到您的项目并导入您的课程中
#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
}
推特
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
}
【讨论】：
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 SLServiceType，例如 SLServiceTypeFacebook 和 SLServiceTypeTwitter
这将基本上检查他们是否在其设置中本地连接了这些服务。我认为您不能要求用户将其添加到他们的设置中。大多数情况下，如果某个特定的共享选项不可用，例如 UIActionSheet，它就不会显示。
我的猜测是您可以使用SLComposeViewController 来检查已连接的帐户，如果未连接，请使用适当的 SDK 将其帐户与您的 iOS 应用程序连接。
