【问题描述】：

如何在 ios Facebook SDK 中上传大型视频？我有一个 4 分钟的视频，总是出现未知错误。

【参考方案1】：

我必须像这样为视频参数构建我的 NSData：

videoData = [NSData dataWithContentsOfURL:url options:NSDataReadingMappedAlways error:&error];

我还必须在 FBRequestConnection.m 中更改此方法，然后事情开始起作用了：

//
// Generates a URL for a batch containing only a single request,
// and names all attachments that need to go in the body of the
// request.
//
// The URL contains all parameters that are not body attachments,
// including the session key if present.
//
// Attachments are named and referenced by name in the URL.
//
- (NSString *)urlStringForSingleRequest:(FBRequest *)request forBatch:(BOOL)forBatch

    [request.parameters setValue:@"json" forKey:@"format"];
    [request.parameters setValue:kSDK forKey:@"sdk"];
    NSString *token = request.session.accessTokenData.accessToken;
    if (token) 
        [request.parameters setValue:token forKey:kAccessTokenKey];
        [self registerTokenToOmitFromLog:token];
    

    NSString *baseURL;
    if (request.restMethod) 
        if (forBatch) 
            baseURL = [kBatchRestMethodBaseURL stringByAppendingString:request.restMethod];
         else 
            baseURL = [kRestBaseURL stringByAppendingString:request.restMethod];
        
     else 
        if (forBatch) 
            baseURL = request.graphpath;
         else 
            NSString *const kVideoGraphBaseURL = @"https://graph-video." FB_BASE_URL @"/";
            if (([request.HTTPMethod isEqualToString:@"PUT"] || [request.HTTPMethod isEqualToString:@"POST"]) && [request.graphPath rangeOfString:@"videos"].location != NSNotFound)
            
                baseURL = [kVideoGraphBaseURL stringByAppendingString:request.graphPath];
            
            else
            
                baseURL = [kGraphBaseURL stringByAppendingString:request.graphPath];
            
        
    

    NSString *url = [FBRequest serializeURL:baseURL
                                     params:request.parameters
                                 httpMethod:request.HTTPMethod];
    return url;

iOS SDK 中的视频支持似乎很差。

【讨论】：

如果我没记错的话，你不能上传超过 12 兆字节的视频（它写在 Facebook 技术文档中）
