Question

由于Facebook SDK每小时都在变化，因此很难获得适用于当前SDK版本的实际教程。一些变化是激进的！

我正在尝试上传照片......但问题是我的FBSessionDelegate方法“fbDidLogin”永远不会被调用。我登录，回到应用程序，但没有任何反应：/

我想我的Session Delegate存在问题：/

这个新SDK的主要变化是关于委托...你在视图中设置委托一次加载而不是设置它[facebook authorize：permissions delegate：self];

我尝试过发现视频（教程）：http://developers.facebook.com/blog/post/532/

这是我的.H

#import "Facebook.h"

@interface sampleClass : UIViewController 
                             <FBSessionDelegate, FBRequestDelegate> {

    Facebook * facebook;
}

@property (strong, nonatomic) Facebook * facebook;

- (IBAction)uploadPhoto:(id)sender;

这是我的.M

- (void)viewDidLoad {
    [super viewDidLoad];

    facebook = [[Facebook alloc] initWithAppId:kAppId andDelegate:self];
}

- (IBAction)uploadPhoto:(id)sender {

     NSArray* permissions = [[NSArray alloc] initWithObjects:
                            @"offline_access", @"publish_stream", nil];

    [facebook authorize:permissions];

}

#pragma mark - Facebook Session Delegate Methods

- (void)fbDidLogin {
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"mov"];
    NSData *videoData = [NSData dataWithContentsOfFile:filePath];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               videoData, @"video.mov",
                               @"video/quicktime", @"contentType",
                               @"Video Test Title", @"title",
                               @"Video Test Description", @"description",
                               nil];
    [facebook requestWithGraphPath:@"me/videos"
                     andParams:params
                 andHttpMethod:@"POST"
                   andDelegate:self];
}

-(void)fbDidNotLogin:(BOOL)cancelled {
NSLog(@"did not login");
}


#pragma mark - Facebook Request Delegate Methods

- (void)request:(FBRequest *)request didLoad:(id)result {
if ([result isKindOfClass:[NSArray class]]) {
    result = [result objectAtIndex:0];
}
NSLog(@"Result of API call: %@", result);
}

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error {
    NSLog(@"Failed with error: %@", [error localizedDescription]);
}



#pragma mark - Support SSO for Facebook


- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    return [self.facebook handleOpenURL:url];
}

Answer 1

您需要输入您的应用程序代表。

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url

并将'Facebook * facebook'变量放在Application Delegate和View Controller都可以访问的位置。

您可以按照本指南进一步说明

你有没有工作？您是否尝试过使用Hackbook作为示例？它以sdk下载为例。此链接指的是演示应用程序，但它现在称为Hackbook。 http://thinkdiff.net/facebook/how-to-develop-facebook-application-for-iphone/
