objc sdk通过AVFile上传文件block没有回调(已解决）

[zxllf23]

问题描述

ps 问题已解决，原因在末尾

在Macos应用中进行文件上传(系统版本10.14.5)
代码如下，通过AVFile上传文件

        AVFile *f = [AVFile fileWithLocalPath:file.srtPath error:&ferror];
        EXIT_IF_ERROR(ferror);
        dispatch_group_enter(group);
        NSLog(@"Begin Upload %@",file.srtPath.lastPathComponent);//日志跟踪这里有执行到
        [f uploadWithProgress:^(NSInteger percent) {
            NSLog(@"Progress %@ %d",file.srtPath.lastPathComponent,percent);//这里不会回调
        } completionHandler:^(BOOL succeeded, NSError * _Nullable error) {
          //macos 系统这里也同样不会回调
            EXIT_IF_ERROR(error);
            file.srtCloudId = f.objectId;
            file.srtCloudUrl = f.url;
            [self saveStatus];
            NSLog(@"Finished Upload %@",file.srtPath.lastPathComponent);
            dispatch_group_leave(group);
        }];

而且控制台有输出以下结果，表示文件上传成功了

------ BEGIN LeanCloud REST Response ------
path: /1.1/fileTokens
cost: 6244.242ms
response: {
    bucket = TDWwApWr;
    createdAt = "2020-06-10T13:50:32.350Z";
    key = "aFXCLCRP5kptWCQZaJpNJ3A.ytenc";
    "mime_type" = "application/octet-stream";
    objectId = 5ee0e5289cba770009cd0514;
    provider = qiniu;
    token = "w6ZYeC-arS2makzcotrVJGjQvpsCQeHcPseFRDzJ:47xq6dUfIZalnWN8aPwY7cszsHI=:eyJpbnNlcnRPbmx5IjoxLCJzY29wZSI6IlREV3dBcFdyIiwibWltZUxpbWl0IjoiISIsImRlYWRsaW5lIjoxNTkxODAwNjMyfQ==";
    "upload_url" = "https://upload.qiniup.com";
    url = "http://file.yingyutingting.com/aFXCLCRP5kptWCQZaJpNJ3A.ytenc";
}
------ END --------------------------------

如题，控制台可以看到上传成功的文件

PS:我把同样的代码，创建了一个ios app，block同样没有回调

已解决

问题已找到，原因是AVFile的block回调都在主线程，而我在代码中用了dispatch_group，并在主线程执行dispatch_group_wait(group, DISPATCH_TIME_FOREVER); 这样会导致主线程一直处于等待状态
