How to use Facebook SDK in iOS? - ios

Question

I am using Facebook sdk in my app and I'm try to login with Facebook button.
This is work in simulator and iPhone 4 but when I'm using iPhone 5 then it's show following error:
error Error Domain=com.facebook.sdk Code=2 "The operation couldn’t be completed. (com.facebook.sdk error 2.)" UserInfo=0x1766e9c0
{com.facebook.sdk:ErrorLoginFailedReason=com.facebook.sdk:SystemLoginCancelled, com.facebook.sdk:ErrorInnerErrorKey=Error Domain=com.apple.accounts Code=7 "The operation couldn’t be completed. (com.apple.accounts error 7.)",
com.facebook.sdk:ErrorSessionKey=<FBSession: 0x1762f0c0, state: FBSessionStateClosedLoginFailed, loginHandler: 0x0, appID: 733184070029762, urlSchemeSuffix: , tokenCachingStrategy:<FBSessionTokenCachingStrategy: 0x17506a20>, expirationDate: (null), refreshDate: (null), attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:(null)>}
my code is here:
if ([[FBSession activeSession] isOpen]) {
/*
* if the current session has no publish permission we need to reauthorize
*/
// if ([[[FBSession activeSession] permissions]indexOfObject:#"public_profile"] == NSNotFound)
{
[[FBSession activeSession] requestNewReadPermissions:[NSArray arrayWithObject:#"public_profile"]
completionHandler:^(FBSession *session,NSError *error){
//[self postPhoto];
[FBRequestConnection
startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"error %#",result);
NSString *facebookId = [result objectForKey:#"id"];
NSLog(#" facebook %#",facebookId );
[self fb_link_check:facebookId];
}
}];
}];
}
}
else
{
FBSession* session = [FBSession activeSession];
[session closeAndClearTokenInformation];
[session close];
[FBSession setActiveSession:nil];
[FBSession openActiveSessionWithReadPermissions:[NSArray arrayWithObject:#"public_profile"] allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if (!error && status == FBSessionStateOpen) {
// [self publishStory];
[FBRequestConnection
startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"error %#",result);
NSString *facebookId = [result objectForKey:#"id"];
NSLog(#" facebook %#",facebookId );
[self fb_link_check:facebookId];
}
}];
}else
{
NSLog(#"error %#",error);
}
}];
}
So, can any one help me on this.
Also, there is another thing that when we download new facebook sdk 3.16.1 and click on it for installation, it give following error:
The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.)
Couldn't open "facebook-ios-sdk-3.16.1(1).pkg".
