Question

我尝试使用Application Scripting Bridge将我的Mac发送到睡眠状态。代码如下所示：

#import "Finder.h"
 FinderApplication *Finder = [SBApplication applicationWithBundleIdentifier:@"com.apple.finder"];
        [Finder sleep];

但它不起作用。任何想法为什么它不起作用？没有编译错误或警告，但它不起作用......

当我在this answer发布时，我已经使用以下代码超过8年没有问题：

MDRestartShutdownLogout.h：

#import <CoreServices/CoreServices.h>
/*
    *    kAERestart        will cause system to restart
    *    kAEShutDown       will cause system to shutdown
    *    kAEReallyLogout   will cause system to logout
    *    kAESleep          will cause system to sleep
 */
extern OSStatus MDSendAppleEventToSystemProcess(AEEventID eventToSend);

MDRestartShutdownLogout.m：

#import "MDRestartShutdownLogout.h"

OSStatus MDSendAppleEventToSystemProcess(AEEventID eventToSendID) {
    AEAddressDesc targetDesc;
    static const ProcessSerialNumber kPSNOfSystemProcess = {0, kSystemProcess };
    AppleEvent eventReply = {typeNull, NULL};
    AppleEvent eventToSend = {typeNull, NULL};

    OSStatus status = AECreateDesc(typeProcessSerialNumber,
         &kPSNOfSystemProcess, sizeof(kPSNOfSystemProcess), &targetDesc);

    if (status != noErr) return status;

    status = AECreateAppleEvent(kCoreEventClass, eventToSendID,
          &targetDesc, kAutoGenerateReturnID, kAnyTransactionID, &eventToSend);

    AEDisposeDesc(&targetDesc);

    if (status != noErr) return status;

    status = AESendMessage(&eventToSend, &eventReply,
                          kAENormalPriority, kAEDefaultTimeout);

    AEDisposeDesc(&eventToSend);
    if (status != noErr) return status;
    AEDisposeDesc(&eventReply);
    return status;
}

请注意，上述代码基于Technical Q&A QA1134中的代码，但我的代码重新使用AESendMessage()而不是AESend()。 AESend()位于HIToolbox.framework，位于Carbon.framework，因此64位应用无法使用。（AESendMessage()是AE.framework）中CoreServices的一部分。

如果Scripting Bridge不足以执行非特定于应用程序的操作，例如关闭Mac，那么您可以轻松转移到其他框架，Applescript（以及扩展的Scripting Bridge）无法直接访问。要关闭Mac，请参阅核心服务：Technical Q&A QA1134: Programmatically causing restart, shutdown and/or logout
