Getting Email Address from LinkedIn API - ios

Question

I want to include a "Sign Up using LinkedIn" feature in my app.
I'd like to be able to get some information, such as name and email.
By default I am able to get a name, but I'm stuck on getting the email.
My results are in JSON.
Here's my code:
- (IBAction)logInWithLinkedIn:(id)sender
{
if ([_client validToken])
{
[self requestMeWithToken:[_client accessToken]];
}
else
{
[_client getAuthorizationCode:^(NSString *code)
{
[self.client getAccessToken:code success:^(NSDictionary *accessTokenData) {
NSString *accessToken = [accessTokenData objectForKey:#"access_token"];
[self requestMeWithToken:accessToken];
} failure:^(NSError *error) {
NSLog(#"Quering accessToken failed %#", error);
}];
} cancel:^{
NSLog(#"Authorization was cancelled by user");
} failure:^(NSError *error) {
NSLog(#"Authorization failed %#", error);
}];
}
}
- (void)requestMeWithToken:(NSString *)accessToken
{
[self.client GET:[NSString stringWithFormat:#"https://api.linkedin.com/v1/people/~?oauth2_access_token=%#&format=json", accessToken] parameters:nil success:^(AFHTTPRequestOperation *operation, NSDictionary *result) {
NSLog(#"current user %#", result);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"failed to fetch current user %#", error);
}];
}
- (LIALinkedInHttpClient *)client
{
LIALinkedInApplication *application = [LIALinkedInApplication applicationWithRedirectURL:#"redirectURL"
clientId:#"key"
clientSecret:#"secret"
state:#"state"
grantedAccess:#[#"r_emailaddress"]];
return [LIALinkedInHttpClient clientForApplication:application presentingViewController:nil];
}
My result is:
firstName
headline
lastName
siteStandardProfileRequest
Anyone see how I can get the email?

Answer 1

You should use:
[self.client GET:[NSString stringWithFormat:#"https://api.linkedin.com/v1/people/~:(id,first-name,last-name,maiden-name,email-address)?oauth2_access_token=%#&format=json", accessToken] parameters:nil success:^(AFHTTPRequestOperation *operation, NSDictionary *result)
This may helps :)

You can use LinkedIn SDK
+ (void)loginToLinkedInAndFetchProfileData:(RequestResult)resultHandler
{
void (^PerformDataFetch)() = ^() {
if ([LISDKSessionManager hasValidSession]) {
NSString *urlString = [NSString stringWithFormat:#"%#/people/~:(id,first-name,last-name,maiden-name,email-address)", LINKEDIN_API_URL];
[[LISDKAPIHelper sharedInstance] getRequest:urlString success:^(LISDKAPIResponse *response) {
NSString *token = [[LISDKSessionManager sharedInstance].session.accessToken serializedString];
[[NSUserDefaults standardUserDefaults] setValue:token forKey:LinkedInAccessTokenKey];
[[NSUserDefaults standardUserDefaults] synchronize];
NSData *objectData = [response.data dataUsingEncoding:NSUTF8StringEncoding];
id value = [NSJSONSerialization JSONObjectWithData:objectData options:kNilOptions error:nil];
resultHandler(value, nil);
} error:^(LISDKAPIError *error) {
resultHandler(nil, error);
}];
}
};
NSString *token = [[NSUserDefaults standardUserDefaults] stringForKey:LinkedInAccessTokenKey];
if (token.length) {
LISDKAccessToken *accessToken = [LISDKAccessToken LISDKAccessTokenWithSerializedString:token];
if ([accessToken.expiration isLaterThan:[NSDate date]]) {
[LISDKSessionManager createSessionWithAccessToken:accessToken];
PerformDataFetch();
}
} else {
[LISDKSessionManager createSessionWithAuth:[NSArray arrayWithObjects:LISDK_BASIC_PROFILE_PERMISSION, LISDK_EMAILADDRESS_PERMISSION, nil] state:nil showGoToAppStoreDialog:YES successBlock:^(NSString *returnState) {
PerformDataFetch();
} errorBlock:^(NSError *error) {
resultHandler(nil, error);
}];
}
}
Response
> {
> emailAddress = "someEmail#email.com";
> firstName = Name;
> id = "2342d-6Y";
> lastName = LastName;

Update for Swift 3:
// Set preferred scope.
let scope = "r_basicprofile%20r_emailaddress"
// Then
if let accessToken = UserDefaults.standard.object(forKey: "LIAccessToken") {
// Specify the URL string that we'll get the profile info from.
let targetURLString = "https://api.linkedin.com/v1/people/~:(id,first-name,last-name,maiden-name,email-address)?format=json"

-(void)syncLinkedInWithCompetionHandler:(CompletionBlock)block{

state:#"some state"

block(returnState, nil);
}
errorBlock:^(NSError *error) {

block(nil, error);
}
];
}
-(void)getProfileDataWithCompletion:(CompletionBlock)block {
NSString *urlString = [NSString stringWithFormat:#"%#/people/~:(id,first-name,last-name,headline,location,email-address)", LINKEDIN_API_URL];

[[LISDKAPIHelper sharedInstance] getRequest:urlString success:^(LISDKAPIResponse *response) {
