iOS 上传视频出错，QiniuErrorDomain Code=2 The request timed out.

Question

最近用Qiniu iOS-SDK 里面的Demo尝试上传视频。 上传一半左右时出错。

出错信息：

2013-11-02 23:06:19.968 QiniuDemo[265:60b] Failed uploading /private/var/mobile/Applications/XXXXXXXX-140A-487D-A77E-XXXXXXXX/tmp/2013-11-03-03-05-52mov with error: Error Domain=QiniuErrorDomain Code=2 "The operation couldn’t be completed. (QiniuErrorDomain error 2.)" UserInfo=0x155b8c30 {error=The request timed out}

少做修改的上传代码：

QiniuDemo/QiniuViewController.m

- (void)uploadContent:(NSDictionary *)theInfo {

    //obtaining saving path

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat: @"yyyy-MM-dd-HH-mm-ss"];
    //Optionally for time zone conversions
    [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];

    NSString *timeDesc = [formatter stringFromDate:[NSDate date]];

    [formatter release];

    //extracting image from the picker and saving it
    NSString *mediaType = [theInfo objectForKey:UIImagePickerControllerMediaType];

    NSString *key = [NSString stringWithFormat:@"%@%@", timeDesc, @".mov"];
    NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:key];
    NSLog(@"Upload Path: %@", filePath);

    NSData *webData = [NSData dataWithContentsOfFile:[[theInfo objectForKey:UIImagePickerControllerMediaURL] path]];
    [webData writeToFile:filePath atomically:YES];

    [self uploadFile:filePath bucket:QiniuBucketName key:key];
}

这是上传客户端判断超时，七牛 iOS-SDK 用了 ASIHTTPRequest 库，其有默认超时时间，你可以将其调大，可参考这个。

如果上传的资源比较大，推荐使用断点续上传，看这里 。

同时请检查上传链路是不是有问题。
