ios - iphone - 如何在使用 Facebook IOS SDK 创建事件时添加图像

Question

我有以下代码来添加一个事件，一切正常并加载到 facebook，没有任何问题，唯一的问题是图像没有上传，iOS 文档中也没有任何类型的帮助，也许我正在寻找错误的地方？也许您经历过这种情况并且可以提供帮助。谢谢

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 [delegate facebook].accessToken, @"access_token",
                                 @"Going To Eat!", @"name",
                                 @"description of the event", @"description",
                                 @"2012-08-20T17:00:00+0000", @"start_time",
                                 @"2012-08-21T17:00:00+0000", @"end_time",
                                 @"Carlsbad", @"city",
                                 @"CA", @"state",
                                 @"900 safe street", @"street",
                                 @"OPEN", @"privacy",
                                 @"https://.../img/faces/pizza-port-brewing-carlsbad.jpg", @"@file.jpg",
                                 nil];

  [[delegate facebook] requestWithGraphPath:@"me/events" 
                        andParams:params
                    andHttpMethod:@"POST"
                      andDelegate:self];

好吧，如果您使用当前的 iOS 版 Facebook API，那么您可以将 UIImage 对象传递给 requestWithGraphPath:调用它会自动检测它并将其上传到您的事件图标。如果它是图像链接，则从 NSURL 中创建 UIImage。

UIImage *image = [[UIImage alloc]initWithImageNamed@"test.png"];    
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 [delegate facebook].accessToken, @"access_token",
                                 @"Going To Eat!", @"name",
                                 @"description of the event", @"description",
                                 @"2012-08-20T17:00:00+0000", @"start_time",
                                 @"2012-08-21T17:00:00+0000", @"end_time",
                                 @"Carlsbad", @"city",
                                 @"CA", @"state",
                                 @"900 safe street", @"street",
                                 @"OPEN", @"privacy",
                                 image, @"picture",
                                 nil];

  [[delegate facebook] requestWithGraphPath:@"me/events" 
                        andParams:params
                    andHttpMethod:@"POST"
                      andDelegate:self];
