与Facebook SDK 4.0 + iOS共享内容

本文介绍了与Facebook SDK 4.0 + iOS共享内容的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用iOS(objective-c)上的Facebook SDK来在Facebook上共享图像.这是我使用的代码:

I use the Facebook SDK on iOS (objective-c) to share an image on Facebook. Here's the code that I use:

-(IBAction)facebookShare:(UIButton *)sender {
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = self.image;
photo.userGenerated = YES;
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = @[photo];
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self];
}

其中image是我通过从用户的库中选择它设置的UIImage.当我尝试按下按钮(使用此IBAction)时，应用程序崩溃，并显示以下错误:

Where image is an UIImage that I set by picking it from the user's gallery. When I try to press my button (with this IBAction) the app crashes giving this error:

以这种方式修复代码后，这是新的错误

here's the new error after fixing the code in this way

FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
        photo.image = //YOUR IMAGE                                                                 photo.userGenerated = YES;
        FBSDKSharePhotoContent * photoContent = [[FBSDKSharePhotoContent alloc] init];
        photoContent.photos = @[photo];
        FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init];
        shareDialog.shareContent = photoContent;
        shareDialog.delegate = (id)self;
        shareDialog.fromViewController = self;
        NSError * error = nil;
        BOOL validation = [shareDialog validateWithError:&error];
        if (validation) {
            [shareDialog show];
        }

最后使用其他仿真器解决了

Finally solved using a different Emulator.

推荐答案

在FB SDK的早期版本中存在一个错误，但是在这里看来您缺少必需的委托方法实现.

There was a bug in the earlier version of FB SDK, but here it seems that you are missing a required implementation of a delegate methods.

        FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
        photo.image = //YOUR IMAGE                                                                 photo.userGenerated = YES;
        FBSDKSharePhotoContent * photoContent = [[FBSDKSharePhotoContent alloc] init];
        photoContent.photos = @[photo];
        FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init];
        shareDialog.shareContent = photoContent;
        shareDialog.delegate = (id)self;
        shareDialog.fromViewController = self;
        NSError * error = nil;
        BOOL validation = [shareDialog validateWithError:&error];
        if (validation) {
            [shareDialog show];
        }

并实现所需的委托方法

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {
    // handle
}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error{
    // handle
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer{
    // handle
}
