7、添加成功后，iOS的需要把Bundle id填写进去，必需要和项目里的填写一致，然后保存，并且应用模式的开关需要打开

二、项目配置
1、项目中通过pod集成SDK，手动集成也可以
pod 'FBSDKCoreKit'
pod 'FBSDKShareKit'
2、在info.plist文件中添加以下代码：
<key>FacebookAppID</key>
<string>应用编号</string>
<key>FacebookClientToken</key>
<string>应用密钥</string>
<key>FacebookDisplayName</key>
<string>app名称</string>
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>CFBundleURLName</key>
<string>com.clatia.plamclati</string>
<key>CFBundleURLSchemes</key>
<array>
<string>fb应用编号</string>
</array>
</dict>
</array>
<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbapi</string>
<string>fb-messenger-api</string>
<string>fb-messenger-share-api</string>
<string>fbauth2</string>
<string>fbshareextension</string>
</array>
3、在Appdelegate中，导入#import <FBSDKCoreKit/FBSDKCoreKit.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
return YES;
}
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options{
BOOL result = [[FBSDKApplicationDelegate sharedInstance] application:app openURL:url sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey] annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
return result;
}
4、在进行分享的地方处理逻辑
FBSDKShareLinkContent*linkContent = [[FBSDKShareLinkContent alloc]init];
linkContent.contentURL= [NSURL URLWithString:@"分享链接"];
linkContent.quote = @"描述信息";
FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc]init];
// 需要指定模式，否则会调起web分享
shareDialog.mode = FBSDKShareDialogModeNative;
if (![shareDialog canShow]) {
shareDialog.mode = FBSDKShareDialogModeWeb;
}
shareDialog.shareContent = linkContent;
shareDialog.delegate = self;
shareDialog.fromViewController = self;
[shareDialog show];
5、实现代理方法
分享后代理方法总是回调到sharerDidCancel，有知道原因和解决方法的小伙伴麻烦告知下
#pragma mark - FBSDKSharingDelegate
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary<NSString *,id> *)results {
NSString *postId = results[@"postId"];
FBSDKShareDialog *dialog = (FBSDKShareDialog *)sharer;
if (dialog.mode == FBSDKShareDialogModeBrowser && (postId == nil || [postId isEqualToString:@""])) {
// 如果使用webview分享的，但postId是空的，
// 这种情况是用户点击了『完成』按钮，并没有真的分享
NSLog(@"Cancel");
} else {
NSLog(@"Success");
}
}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error {
FBSDKShareDialog *dialog = (FBSDKShareDialog *)sharer;
if (error == nil && dialog.mode == FBSDKShareDialogModeNative) {
// 如果使用原生登录失败，但error为空，那是因为用户没有安装Facebook app
// 重设dialog的mode，再次弹出对话框
dialog.mode = FBSDKShareDialogModeBrowser;
[dialog show];
} else {
NSLog(@"Failure");
}
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer {
NSLog(@"Cancel");
}
