Facebook iOS sdk xcode 4.3 / storyboards [英] Facebook iOS sdk xcode 4.3/storyboards

问题描述

我一直在看几周教程，无法找到在iOS中实现FB的任何故事板示例。

我有我的应用程序打开FBloginscreen，请求用户认证的应用程序，然后返回到应用程序...
像一些其他用户，fbdidlogin和handleopenurl方法不被调用。我确定我做错了事，但不知道什么。
i am在我的故事板中使用默认视图控制器（我没有创建一个vc程序的
），所以我可能需要做一些事情。

从我的理解，handleopenurl方法需要在我的应用程序委托文件，而不是在我的视图controller.m文件，但我不知道如何应该写，如何连接一个UIViewController对象我创建到VC在我的故事板（带有我正在使用的按钮和标签的故事板）中。

  ViewController.h（与FB相关）
 
 #importFBConnect.h
 
 @interface ViewController：UIViewController 
< UIImagePickerControllerDelegate，
 UINavigationControllerDelegate，FBSessionDelegate，FBDialogDelegate> 
 {
 Facebook * facebook; 
} 
 
 @property（非原子，保留）Facebook * facebook;'
  

---

  ViewController.m（与FB相关）
 
 #importViewController.h
 
 @implementation ViewController; 
 @synthesize Facebook; 
 
  - （void）LogintoFB 
 {
 facebook = [[Facebook alloc] initWithAppId：@345872345487883andDelegate：self]; 
 NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; 
 if（[defaults objectForKey：@FBAccessTokenKey] 
&&&&default; ]。 
 facebook.expirationDate = [defaults objectForKey：@FBExpirationDateKey]; 
} 
 if（！[facebook isSessionValid]）{
 [facebook authorize：nil]; 
 NSLog（@登录）; 
} 
 
 
} 
 //前iOS 4.2支持
  - （BOOL）应用程序：（UIApplication *）应用程序handleOpenURL :( NSURL *）url {
 NSLog（@ -  4.2 got calleld）; 
 return [facebook handleOpenURL：url]; 
} 
 //对于iOS 4.2+支持
  - （BOOL）应用程序：（UIApplication *）应用程序openURL：（NSURL *）url 
 sourceApplication：（NSString *）sourceApplication注释：（id）annotation {
 NSLog（@4.2+被调用）; 
 return [facebook handleOpenURL：url]; 
} 
} 
  - （void）fbDidLogin {
 NSLog（@fbDidLogin）; 
 NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; 
 [defaults setObject：[facebook accessToken] forKey：@FBAccessTokenKey]; 
 [defaults setObject：[facebook expirationDate] forKey：@FBExpirationDateKey]; 
 [默认同步]; 
 
 
 [Facebook对话框：@feedandDelegate：self]; 
 
 
}'

谢谢！

$ b如果你可以指导我在iOS中实现Facebook的故事板。 $ b

解决方案

- （BOOL）应用程序：openURL：sourceApplication：注释：应该在应用程序中实现代理。

将属性添加到appDelegate中：

  @property （非原子，强力）Facebook * facebook; 
  

合成它！

在你的登录到创建Facebook对象后添加此方法
（AppDelegate应该是你的appDelegate类名称）

  AppDelegate * appDelegate = [[UIApplication sharedApplication] delegate]; 
 appDelegate.facebook = facebook; 
  

i have been looking at tutorials for weeks now, not been able to find ANY storyboard examples implementing FB in iOS.

i got my app to open the FBloginscreen, request user auth for app, and then return to app... like some other users , fbdidlogin and handleopenurl method are not called. i am sure i am doing something wrong but just don't know what. i am using the default view controller in my storyboard (i did not create a vc programatically ) so i might need to do something with that.

from what i understand that handleopenurl method needs to be in my app delegate.m file and not in my view controller.m file, but i am not sure how it should be written and how to connect a UIViewController object i create to the VC in my storyboard (the one with the buttons and labels that i am using).

ViewController.h (relevant to FB)

#import "FBConnect.h"

@interface ViewController : UIViewController
<UIImagePickerControllerDelegate, 
UINavigationControllerDelegate, FBSessionDelegate, FBDialogDelegate>
{
Facebook *facebook; 
}

@property (nonatomic,retain) Facebook *facebook;'

---

ViewController.m (relevant to FB)

#import "ViewController.h"

@implementation ViewController;
@synthesize facebook;   

-(void)LogintoFB
{
    facebook = [[Facebook alloc] initWithAppId:@"345872345487883" andDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }
    if (![facebook isSessionValid]) {
        [facebook authorize:nil];
        NSLog(@"did log in");
    }


}
// Pre iOS 4.2 support
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    NSLog(@"-4.2 got calleld");
    return [facebook handleOpenURL:url]; 
}
// For iOS 4.2+ support
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    NSLog(@"4.2+ got called");
    return [facebook handleOpenURL:url]; 
}
}
- (void)fbDidLogin {
    NSLog(@"fbDidLogin");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];


    [facebook dialog:@"feed" andDelegate:self];


}'

also if you can direct me to a tutorial that used storyboard when implementing Facebook in iOS that would be great.

thank you!

解决方案

-(BOOL)application:openURL:sourceApplication:annotation: should be implemented in the app delegate.

Add a property to the appDelegate :

@property (nonatomic, strong) Facebook *facebook;

Synthesize it!

In your logintoFB method add this after creating the Facebook object (AppDelegate should be whatever your appDelegate class name is)

AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
appDelegate.facebook = facebook;
