我目前正在开发Facebook SDK 4.4.0。在4.4.0版本之前,在4.3.0中我们收到了带有以下代码的电子邮件public_profile
NSArray *arrFBPermission = [[NSArray alloc]initWithObjects:@"email",@"public_profile", nil];
[loginUsingFB logInWithReadPermissions:arrFBPermission handler:^(FBSDKLoginManagerLoginResult *result, NSError *error){
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error){
if (!error){
NSString *fnm = [result valueForKey:@"first_name"];
NSString *lnm = [result valueForKey:@"last_name"];
}
else{
Nslog("%@", error localizedDescription);
}
}];
}
现在在新的SDK(即4.4.0)中,我没有得到这些值。为什么?我想要来自Facebook的电子邮件,first_name,last_name,id。

使用Facebook 4.4 SDK会有轻微的变化。
您必须使用您想要的Facebook帐户FBSDKGraphRequest
请求参数。
在您的代码中,参数中有nil
:
使用如下参数更新代码:
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location , friends ,hometown , friendlists"}]
如果您想使用自定义按钮登录Facebook,则可以使用以下完整代码:
- (IBAction)btnFacebookPressed:(id)sender {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior = FBSDKLoginBehaviorBrowser;
[login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
{
if (error)
{
// Process error
}
else if (result.isCancelled)
{
// Handle cancellations
}
else
{
if ([result.grantedPermissions containsObject:@"email"])
{
NSLog(@"result is:%@",result);
[self fetchUserInfo];
[login logOut]; // Only If you don't want to save the session for current app
}
}
}];
}
-(void)fetchUserInfo
{
if ([FBSDKAccessToken currentAccessToken])
{
NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]);
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email"}]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error)
{
NSLog(@"resultis:%@",result);
}
else
{
NSLog(@"Error %@",error);
}
}];
}
}
我希望它对你有用。
