                    case AVAssetExportSessionStatusCancelled: {
                        NSLog(@"AVAssetExportSessionStatusCancelled");
                        if (failure) {
                            failure(@"导出任务已被取消", nil);
                        }
                    }  break;
                    default: break;
                }
            });
        }];
    }];
}

这样可以正常导出，基本上跟原来的导出方法类似，只是把requestAVAssetForVideo方法换成requestExportSessionForVideo。
