我正在使用 facebook sdk 在 facebook 上共享文本,但在尝试登录时无法获取访问 token 。登录成功,但没有获得任何访问 token 。 因此,如果没有访问 token ,我将无法在 facebook 上分享文本。 我的代码如下
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions[@"public_profile"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if ([result.token hasGranted"publish_actions"]) {
[[[FBSDKGraphRequest alloc]
initWithGraphPath"me/feed"
parameters: @{ @"message" : @"hello world"}
HTTPMethod"OST"]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(@"ost id:%@", result[@"id"]);
}
}];
}
if (error) {
// Process error
} else if (result.isCancelled) {
// Handle cancellations
} else {
// If you ask for multiple permissions at once, you
// should check if specific permissions missing
if ([result.grantedPermissions containsObject"email"]) {
// Do work
}
}
}];
我在 FBSDKLoginManager 对象的处理程序 block 中得到结果,没有错误,但它不包含 token 或其他数据
输出如下
请告诉我如何解决这个问题 谢谢
试试这个代码。基于 Facebook SDK 4.0 版
AppDalegate.m
- (BOOL)applicationUIApplication *)application openURLNSURL *)url sourceApplicationNSString *)sourceApplication annotationid)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
}
ViewController.m
- (IBAction)btnFacebookPressedid)sender {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[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];
}
}
}];
}
-(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, birthday, bio ,location ,friends ,hometown , friendlists"}]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error)
{
NSLog(@"resultis:%@",result);
}
else
{
NSLog(@"Error %@",error);
}
}];
}
}
关于ios - 尝试登录 iOS sdk 时无法通过 FBSDKLoginKit 获取访问 token ,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/30248048/
