请在这里查看facebook developer https://developers.facebook.com/docs/reference/api/event/的文档。其中你可以找到包含图像的参数“图片”

Answer 2

好吧我想通了，如果你使用IOS的当前Facebook API，那么你可以传递一个UIImage对象到requestWithGraphPath：它会自动检测它并上传它到你的活动图标。如果它的图像链接然后使用NSURL创建一个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];
