IOS：在未安裝應用程序時，LinkedIn登錄未重定向到網頁

Question

我試圖在我的ios應用程序中集成linkedin。我觀察到如果沒有安裝應用程序我的應用程序顯示安裝linkedin應用程序而不是重定向到像facebook和gmail這樣的web瀏覽器。我想知道weather linkedin支持這種事情，如果沒有安裝應用程序重定向到網頁，或者我必須為此編寫自定義代碼。如果是這樣，請幫助我在未安裝linkedin應用程序時以及安裝時編寫自定義代碼。 在我的應用程序中集成linkedin sdk后，我編寫了如下代碼。

 LISDKSessionManager createSessionWithAuth:[NSArray arrayWithObjects:LISDK_BASIC_PROFILE_PERMISSION, LISDK_EMAILADDRESS_PERMISSION, nil]
 state:nil
 showGoToAppStoreDialog:YES
 successBlock:^(NSString *returnState) {
     NSLog(@"%s","success called!");
     LISDKSession *session = [[LISDKSessionManager sharedInstance] session];
     NSLog(@"value=%@ isvalid=%@",[session value],[session isValid] ? @"YES" : @"NO");
     NSMutableString *text = [[NSMutableString alloc] initWithString:[session.accessToken description]];
     [text appendString:[NSString stringWithFormat:@",state=\"%@\"",returnState]];
     NSLog(@"Response label text %@",text);
 }
 errorBlock:^(NSError *error) {
     NSLog(@"%s","error called!");
 }
 ];

如果您的設備上未安裝該應用，則會調用錯誤阻止，您必須向用戶顯示您必須從應用商店下載應用的提醒。 用戶可以單擊“否”，然后使用OAuth登錄。

-(void)loginViaLinkedIn
 {
  __weak __typeof(self)weakSelf = self;
[LISDKSessionManager createSessionWithAuth:[NSArray 
arrayWithObjects:LISDK_BASIC_PROFILE_PERMISSION, nil]
                                     state:@"some state"
                    showGoToAppStoreDialog:YES
                              successBlock:^(NSString *returnState) {

                                  NSLog(@"%s","success called!");
                                  LISDKSession *session = [[LISDKSessionManager sharedInstance] session];
                                  NSLog(@"value=%@ isvalid=%@",[session value],[session isValid] ? @"YES" : @"NO");
                                  [weakSelf getLinkedInDetail];
                              }
                                errorBlock:^(NSError *error) {
                                    NSDictionary * userInfoDic = [error userInfo];
                                    NSString * info = [[userInfoDic allKeys] firstObject];
                                    if([info isEqualToString:@"You need to download the LinkedIn App in order to connect with LinkedIn"] && error.code == 3)
                                    {
                                        [weakSelf loginViaOAuthProtocol];
                                        // Linkedin native app not available , login with OAuth
                                    }
                                    else
                                    {
                                        [weakSelf linkedinAuthenticationResponse:nil error:error];
                                    }
                                }
 ];

 }

您可以閱讀有關它的官方文檔。 “了解移動身份驗證用戶體驗”根據以下情況，可能會出現幾種可能導致不同用戶體驗的情況：

-Is the LinkedIn application installed on the device?
-Is the user a LinkedIn member?
-Is the user signed into the LinkedIn application on their device?
-Has the user granted your application permission to access their profile?

所有這些都在以下內容中解釋： https ： //developer.linkedin.com/docs/ios-sdk-auth#ux
