iOS13上传相册视频Code=1 “Operation not permitted”

在做文件上传时候，发现iOS13上，选择相册的视频上传，会报无权限访问文件的错误，iOS13以下的系统不会出这个问题，可能部分机型上会有吧，但是我没发现。

报错信息：
Error Domain=NSCocoaErrorDomain Code=257 "The file "trim.166DC0B6-0C86-4EC3-BCBD-F29684A5566C/tmp/1C91514D-C987-4C1C-BEBF-6A7F071F1435.MOV" couldn't be opened because you don't has permission to view it."

看了下iOS12和iOS13上获取到的文件路径：

iOS12
file:///private/var/mobile/Containers/Data/Application/166DC0B6-0C86-4EC3-BCBD-F29684A5566C/tmp/1C91514D-C987-4C1C-BEBF-6A7F071F1435.MOV";

iOS13
file:///private/var/mobile/Containers/Data/Application/PluginKitPgin/166DC0B6-0C86-4EC3-BCBD-F29684A5566C/tmp/1C91514D-C987-4C1C-BEBF-6A7F071F1435.MOV";

发现iOS12的路径多了一个PluginKitPgin文件夹，这导致文件访问受限。

但是有意思的是通过iOS13的这个路径可以拿到问价你的二进制数据

+ (NSData *)fileData:(NSString *)filePath {
    NSFileHandle *fileHande = [NSFileHandle fileHandleForReadingAtPath:filePath];
    return [fileHande readDataToEndOfFile];
}

这样的话先拿到文件，然后写入沙盒，然后通过沙盒路径去上传就ok了，大致代码是这样的：

//视频文件
if ([mediaType isEqualToString:@"public.movie"])
{
    NSURL *url = [info objectForKey:UIImagePickerControllerMediaURL];
    NSString *videoPath = url.path;

    // <13.0可以直接上传
    if ([[UIDevice currentDevice].systemVersion floatValue] < 13.0)
    {
        //上传
        [self addUploadFileWithPath:videoPath];
    }
    //13.0 先将文件存在在沙盒，然后上传
    else
    {
        NSString *datapath = [self writeFileToDocPaths:videoPath];
        [self addUploadFileWithPath:datapath];
    }
}

将数据写入沙盒中

-(NSString *)writeFileToDocPaths:(NSString *)filePath {
    //读取相册中的文件
    NSData *data = [VHUploaderModel fileData:filePath];
    //将文件写入沙盒
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString *dataPath = [self getFilePath:[NSString stringWithFormat:@"%@",[filePath lastPathComponent]]];
    if (![fileManager fileExistsAtPath:dataPath]) {//文件是否存在
        [fileManager createFileAtPath:dataPath contents:nil attributes:nil];
    }
    NSFileHandle *fileHandle = [NSFileHandle fileHandleForWritingAtPath:dataPath];
    [fileHandle seekToEndOfFile];
    [fileHandle writeData:data];
    [fileHandle closeFile];
    return dataPath;
}
- (NSString *)getFilePath:(NSString *)fileName {
    NSString *docPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,  NSUserDomainMask, YES).firstObject;
    return [docPath stringByAppendingPathComponent:fileName];
}
