在 iOS 9 中使用 Facebook 登录无法打开本机 Facebook 应用程序 [英] Native Facebook app does not open with Facebook login in iOS 9
问题描述
我已将 iPhone 6 plus 更新到 iOS 9 beta 并尝试执行 Facebook 登录，但每次它都显示带有 Facebook 登录表单的 UIWebView.
我有 Facebook sdk
FB_IOS_SDK_VERSION_STRING @"3.24.0"FB_IOS_SDK_TARGET_PLATFORM_VERSION @"v2.2"我正在使用以下方法来执行 Facebook 登录
NSArray *permissions = @[@"email",@"user_birthday",@"public_profile"];FBSessionStateHandler completionHandler = ^(FBSession *session, FBSessionState 状态, NSError *error) {[self sessionStateChanged:session state:status error:error];};如果([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded){//我们有一个缓存的令牌，所以打开会话[[FBSession activeSession]openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent从视图控制器:无完成处理程序:完成处理程序];} 别的 {[self clearAllUserInfo];[[NSURLCache sharedURLCache] removeAllCachedResponses];//创建一个新的 Facebook 会话FBSession *fbSession = [[FBSession alloc] initWithPermissions:permissions];[FBSession setActiveSession:fbSession];[fbSession openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent从视图控制器:无完成处理程序:完成处理程序];}我在 plist 文件下有以下设置
LSApplicationQueriesSchemes <阵列><string>fbapi</string><string>fbapi20130214</string><string>fbapi20130410</string><string>fbapi20130702</string><string>fbapi20131010</string><string>fbapi20131219</string><string>fbapi20140410</string><string>fbapi20140116</string><string>fbapi20150313</string><string>fbapi20150629</string><string>fb-messenger-api20140430</string><string>fbauth</string><string>fbauth2</string><阵列>请让我知道我在这里遗漏了什么.首先是检查 iPhone 设备设置->Facebook 凭据 但从不打开 Facebook 应用程序进行登录.它似乎无法识别设备上安装的 Facebook 应用.
以下是新的Facebook登录"的完整流程.
<小时>这是我修改我的 Facebook 登录集成以使其在最新更新中工作的方式.
<块引用>Xcode 7.x、iOS 9、Facebook SDK 4.x
步骤 1.下载最新的 Facebook SDK(包括重大变化).
第 2 步.将 FBSDKCoreKit.framework 和 FBSDKLoginKit.framework 添加到您的项目中.
第 3 步.现在转到 Project > Build Phases > add SafariServices.framework
第 4 步.我们需要验证 info.plist 中的三处更改.
4.1 确保您的 info.plist 文件中有以下内容
<块引用>CFBundleURLTypes <阵列><字典><key>CFBundleURLSchemes</key><阵列><string><你的 fb id 在这里例如.fbxxxxxx></string></阵列></dict></阵列><key>FacebookAppID</key><string><你的 FacebookAppID></string><key>FacebookDisplayName</key><string><Your_App_Name_Here></string>4.2 现在添加以下白名单 Facebook 服务器，这是 iOS 9 必须的
<块引用>NSAppTransportSecurity <字典><key>NSExceptionDomains</key><字典><key>facebook.com</key><字典><key>NSIncludesSubdomains</key><真/><key>NSExceptionRequiresForwardSecrecy</key><假/></dict><key>fbcdn.net</key><字典><key>NSIncludesSubdomains</key><真/><key>NSExceptionRequiresForwardSecrecy</key><假/></dict><key>akamaihd.net</key><字典><key>NSIncludesSubdomains</key><真/><key>NSExceptionRequiresForwardSecrecy</key><假/></dict></dict></dict>4.3 添加 URL 方案
<块引用>LSApplicationQueriesSchemes <阵列><string>fbapi</string><string>fb-messenger-api</string><string>fbauth2</string><string>fbshareextension</string></阵列>第 5 步.现在打开 AppDelegate.m 文件
5.1 添加下面的导入语句，(删除旧的).
<块引用>#import #import 5.2 更新如下方法
- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)url源应用程序:(NSString *)源应用程序注释:(id)注释{返回 [[FBSDKApplicationDelegate sharedInstance] 应用程序:应用程序打开网址:网址源应用:源应用注释:注释];}- (void)applicationDidBecomeActive:(UIApplication *)application {[FBSDKAppEvents activateApp];}- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {返回 [[FBSDKApplicationDelegate sharedInstance] 应用程序:应用程序didFinishLaunchingWithOptions:launchOptions];}第 6 步.现在我们需要修改我们的登录控制器，我们在这里做登录任务
6.1 在 Login ViewController.m
中添加这些导入<块引用>#import #import 6.2 添加 Facebook 登录按钮
FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];loginButton.center = self.view.center;[self.view addSubview:loginButton];6.3 处理登录按钮点击
-(IBAction)facebookLogin:(id)sender{FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];if ([FBSDKAccessToken currentAccessToken]){NSLog(@"令牌可用:%@",[[FBSDKAccessToken currentAccessToken]tokenString]);[自取用户信息];}别的{[登录 logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error){如果(错误){NSLog(@"登录过程出错");}否则如果(result.isCancelled){NSLog(@"用户取消登录");}别的{NSLog(@"登录成功");if ([result.grantedPermissions containsObject:@"email"]){NSLog(@"结果为:%@",result);[自取用户信息];}别的{[SVProgressHUD showErrorWithStatus:@"Facebook 电子邮件权限错误"];}}}];}}6.4 获取用户信息(姓名、电子邮件等)
-(void)fetchUserInfo{if ([FBSDKAccessToken currentAccessToken]){NSLog(@"令牌可用:%@",[[FBSDKAccessToken currentAccessToken]tokenString]);[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" 参数:@{@"fields": @"id, name, email"}]startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id 结果, NSError *error) {如果(！错误){NSLog(@"结果:%@",result);NSString *email = [result objectForKey:@"email"];NSString *userId = [result objectForKey:@"id"];如果 (email.length > 0 ){//启动你的应用程序Todo}别的{NSLog(@Facebook 邮箱未验证");}}别的{NSLog(@"错误 %@",error);}}];}}第 7 步.现在你可以构建项目了，你应该得到下面的屏幕.
希望对大家有所帮助.

I have updated iPhone 6 plus to iOS 9 beta and trying to perform Facebook login but each time its presenting UIWebView with Facebook login form.
I have Facebook sdk
FB_IOS_SDK_VERSION_STRING @"3.24.0"
FB_IOS_SDK_TARGET_PLATFORM_VERSION @"v2.2"
And I am using following methods to perform Facebook Login
NSArray *permissions = @[@"email",@"user_birthday",@"public_profile"];
FBSessionStateHandler completionHandler = ^(FBSession *session, FBSessionState status, NSError *error) {
[self sessionStateChanged:session state:status error:error];
};
if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded) {
// we have a cached token, so open the session
[[FBSession activeSession]openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
fromViewController:nil
completionHandler:completionHandler];
} else {
[self clearAllUserInfo];
[[NSURLCache sharedURLCache] removeAllCachedResponses];
// create a new facebook session
FBSession *fbSession = [[FBSession alloc] initWithPermissions:permissions];
[FBSession setActiveSession:fbSession];
[fbSession openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
fromViewController:nil
completionHandler:completionHandler];
}
I have following setting under plist file
<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbapi</string>
<string>fbapi20130214</string>
<string>fbapi20130410</string>
<string>fbapi20130702</string>
<string>fbapi20131010</string>
<string>fbapi20131219</string>
<string>fbapi20140410</string>
<string>fbapi20140116</string>
<string>fbapi20150313</string>
<string>fbapi20150629</string>
<string>fb-messenger-api20140430</string>
<string>fbauth</string>
<string>fbauth2</string>
<array>
Please let me know what I am missing here. First it is checking for iPhone device Setting-> Facebook credentials but never open Facebook app for login. Seems it does not recognize Facebook app installed on device.
Below is complete process for new "Facebook login".
this is how I have revised my Facebook Login integration to get it work on latest update.
Xcode 7.x , iOS 9 , Facebook SDK 4.x
Step-1. Download latest Facebook SDK (it includes major changes).
Step-2. Add FBSDKCoreKit.framework and FBSDKLoginKit.framework to your project.
Step-3. Now go to Project > Build Phases > add SafariServices.framework
Step-4. There are three changes in info.plist we need to verify.
4.1 Make sure you have below in your info.plist file
<key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLSchemes</key> <array> <string><your fb id here eg. fbxxxxxx></string> </array> </dict> </array> <key>FacebookAppID</key> <string><your FacebookAppID></string> <key>FacebookDisplayName</key> <string><Your_App_Name_Here></string>
4.2 Now add below for White-list Facebook Servers, this is must for iOS 9
<key>NSAppTransportSecurity</key> <dict> <key>NSExceptionDomains</key> <dict> <key>facebook.com</key> <dict> <key>NSIncludesSubdomains</key> <true/> <key>NSExceptionRequiresForwardSecrecy</key> <false/> </dict> <key>fbcdn.net</key> <dict> <key>NSIncludesSubdomains</key> <true/> <key>NSExceptionRequiresForwardSecrecy</key> <false/> </dict> <key>akamaihd.net</key> <dict> <key>NSIncludesSubdomains</key> <true/> <key>NSExceptionRequiresForwardSecrecy</key> <false/> </dict> </dict> </dict>
4.3 Add URL schemes
<key>LSApplicationQueriesSchemes</key> <array> <string>fbapi</string> <string>fb-messenger-api</string> <string>fbauth2</string> <string>fbshareextension</string> </array>
Step-5. Now open AppDelegate.m file
5.1 Add below import statements, (remove old one).
#import <FBSDKLoginKit/FBSDKLoginKit.h> #import <FBSDKCoreKit/FBSDKCoreKit.h>
5.2 update following following methods
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
[FBSDKAppEvents activateApp];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
return [[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
}
Step-6. Now we need to modify our Login Controller, where we do Login task
6.1 Add these imports in Login ViewController.m
#import <FBSDKCoreKit/FBSDKCoreKit.h> #import <FBSDKLoginKit/FBSDKLoginKit.h>
6.2 Add Facebook Login Button
FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.center = self.view.center;
[self.view addSubview:loginButton];
6.3 Handle Login button click
-(IBAction)facebookLogin:(id)sender
{
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
if ([FBSDKAccessToken currentAccessToken])
{
NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]);
[self fetchUserInfo];
}
else
{
[login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
{
if (error)
{
NSLog(@"Login process error");
}
else if (result.isCancelled)
{
NSLog(@"User cancelled login");
}
else
{
NSLog(@"Login Success");
if ([result.grantedPermissions containsObject:@"email"])
{
NSLog(@"result is:%@",result);
[self fetchUserInfo];
}
else
{
[SVProgressHUD showErrorWithStatus:@"Facebook email permission error"];
}
}
}];
}
}
6.4 Get user info (name, email etc.)
-(void)fetchUserInfo
{
if ([FBSDKAccessToken currentAccessToken])
{
NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]);
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, email"}]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error)
{
NSLog(@"results:%@",result);
NSString *email = [result objectForKey:@"email"];
NSString *userId = [result objectForKey:@"id"];
if (email.length >0 )
{
//Start you app Todo
}
else
{
NSLog(@"Facebook email is not verified");
}
}
else
{
NSLog(@"Error %@",error);
}
}];
}
}
Step-7. Now you can build project, you should get below screen.
Hope this will help you guys.
