我的FB请求输出在iOS中无效。它输出两次到控制台。第一次输出正确的信息,然后立即用(null)而不是正确的数据做同样的事情。
这是我的代码:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
facebook = [[Facebook alloc] initWithAppId:@"fbKEY....." andDelegate:self];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:@"FBAccessTokenKey"]
&& [defaults objectForKey:@"FBExpirationDateKey"]) {
facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
}
//FB check for valid session
if (![facebook isSessionValid]) {
NSArray *permissions = [[NSArray alloc] initWithObjects:
@"user_likes",
@"read_stream",
@"user_location",
@"user_checkins",
// @"publish_actions",
// @"user_activities",
// @"friends_birthday",
nil];
[facebook authorize:permissions];
}
[facebook requestWithGraphPath:@"me" andDelegate:self];
// get the posts made by the "platform" page
[facebook requestWithGraphPath:@"platform/posts" andDelegate:self];
// get the logged-in user's friends
[facebook requestWithGraphPath:@"me/friends" andDelegate:self];
[facebook dialog:@"feed" andDelegate:self];
// Override point for customization after application launch.
return YES;
}
- (void)request:(FBRequest *)request didLoad:(id)result {
NSDictionary *userData = (NSDictionary *)result; // The result is a dictionary
NSString *name = [userData objectForKey:@"name"];
NSString *location = [[userData objectForKey:@"location"] objectForKey:@"name"];
NSString *gender = [userData objectForKey:@"gender"];
NSLog(@"name is %@", name);
NSLog(@"location is %@", location);
NSLog(@"gender is %@", gender);
// NSLog(@"%@",result);
}
这是我的NSLog输出:
