Question

我在一个应用程序组中有2个沙盒应用程序，并尝试将在＃34; Main＆＃34;（代码中的SandboxTest）应用程序中生成的文件传输到＆＃34; Helper＆＃34;（代码中为SandboxPair））申请。使用沙箱它在10.11上工作，在10.12 Sierra上失败。当沙箱关闭时也可以正常工作。

Helper是由Main使用NSTask启动的（我也尝试过NSWorkspace，结果相同）。以下是我启动它并发送文件的方式：

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{       
    //Testing
    _path = [[NSBundle mainBundle] pathForResource:@"SandboxPair" ofType:@"app"];
    _path = [_path stringByAppendingPathComponent:@"/Contents/MacOS/SandboxPair"];
    if( ![self runTaskWithLaunchPath:_path] ) {
        NSLog(@"launching helper app failed");
    }

    [self performSelector:@selector(sendFile) withObject:nil afterDelay:2];

    return;
}

- (BOOL)runTaskWithLaunchPath:(NSString*)launchPath
{
    _helperAppTask = [NSTask new];
    if( ![[NSFileManager defaultManager] fileExistsAtPath:launchPath] )
    {
        NSLog(@"ERROR: Not found command %@", launchPath);
        return NO;
    }

    _helperAppTask.launchPath = launchPath;

    NSPipe* outPipe = [NSPipe pipe];
    NSPipe* errPipe = [NSPipe pipe];
    _helperAppTask.standardOutput = outPipe;
    _helperAppTask.standardError = errPipe;

    [_helperAppTask launch];

    return YES;
}

///Run openFile:withApplication: test
- (void)sendFile
{
    NSString* groupIdentifier = [[[NSBundle mainBundle] objectForInfoDictionaryKey:@"AppIdentifierPrefix"]
                                stringByAppendingString:[[NSBundle mainBundle]
                                objectForInfoDictionaryKey:(NSString*)kCFBundleIdentifierKey]];
    NSURL* sharedPath = [[NSFileManager defaultManager]
                         containerURLForSecurityApplicationGroupIdentifier:groupIdentifier];

    NSError* error = nil;
    [[NSFileManager defaultManager] createDirectoryAtURL:sharedPath
                             withIntermediateDirectories:YES attributes:nil error:&error];
    NSString* fileName = @"test.txt";

    fileName = [[@"~/Downloads/" stringByAppendingPathComponent:fileName]stringByExpandingTildeInPath];
    [@"test file" writeToFile:fileName atomically:YES
                     encoding:NSUTF8StringEncoding error:&error];
    NSLog(@"File written at path: %@", fileName);

    BOOL opened = [[NSWorkspace sharedWorkspace] openFile:fileName withApplication:_path];

    if(!opened) {
        NSLog(@"File was not opened in helper application");
    } else {
        NSLog(@"File was successfully opened in helper application");
    }
}

来自帮助应用程序的AppDelegate.m的接收文件代码：

- (BOOL)application:(NSApplication *)sender openFile:(NSString *)filename
{
    NSAlert* alert = [[NSAlert alloc] init];
    alert.messageText = @"Helper app: File was recieved. application:openFile: is working";
    [alert addButtonWithTitle:@"OK"];
    [alert runModal];
    return YES;
}

- (void)application:(NSApplication *)sender openFiles:(NSArray<NSString *> *)filenames
{
    NSAlert* alert = [[NSAlert alloc] init];
    alert.messageText = @"Helper app: Files was recieved. application:openFiles: is working";
    [alert addButtonWithTitle:@"OK"];
    [alert runModal];
}

您可以在github上看到测试项目：https://github.com/pogosskiy/SierraSandbox 还有一个代码来测试这些进程之间的NSConnection。我试图用它来表示应用程序组Group中有一个文件，但它在沙箱下的10.12也失败了。

我该如何解决这个项目？也许权利中有一些沙箱标志？我已经在com.apple.security.temporary-exception.apple-events中尝试了一些，但没有效果（或者可能有错误）。
