我想在我的iOS应用程序中与FBSDK建立Facebook共享.
我一直在阅读文档here,目前有
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self];
使用内容对象 – FBSDKShareLinkContent.
但是,在尝试使用Facebook Messenger共享指定的类似方法时,
[FBSDKMessageDialog showWithContent:content delegate:self];
我正在崩溃.我发现错误并将其记录在其中一个委托方法中,并指出“操作无法完成.(com.facebook.sdk.share error 202.)
“
我搜索了这个特定的错误,但没有找到任何直接相同的错误.这是完整的代码
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:kAPPShareLink];
content.contentDescription = kAPPShareDescription;
content.contentTitle = kAPPShareTitle;
if (buttonIndex == 0) {
// Facebook
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self];
} else if (buttonIndex == 1) {
// Facebook Messenger
[FBSDKMessageDialog showWithContent:content delegate:self];
}
请原谅我,如果我遗漏了一些明显的东西,但是当this documentation读取时,我认为FBSDKMessageDialog showWithContent：方法的工作方式与FBSDKShareDialog showFromViewController相同：这对我有用.
>我正在使用最新版本的XCode和iOS8.
解决方法
我必须登录然后发布,这是它的工作原理：
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result,NSError *error)
{
if (error)
{
// Process error
}
else if (result.isCancelled)
{
// Handle cancellations
}
else
{
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:@"https://developers.facebook.com/"];
FBSDKMessageDialog *messageDialog = [[FBSDKMessageDialog alloc] init];
messageDialog.delegate = self;
[messageDialog setShareContent:content];
if ([messageDialog canShow])
{
[messageDialog show];
}
else
{
// Messenger isn't installed. Redirect the person to the App Store.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/en/app/facebook-messenger/id454638411?mt=8"]];
}
}
}];
和股份代表：
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results
{
NSLog(@"didCompleteWithResults");
}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error
{
NSLog(@"didFailWithError ::: %@",error);
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer
{
NSLog(@"sharerDidCancel");
}
编辑：
[messageDialog canShow]在iPad上返回NO,在iPhone上运行正常
在Facebook Developers forum上发布了这个问题.
