Question

我试过

LSSharedFileListRef globalLoginItems = LSSharedFileListCreate(NULL, kLSSharedFileListGlobalLoginItems, NULL);
if (globalLoginItems) {
    LSSharedFileListItemRef ourLoginItem = LSSharedFileListInsertItemURL(globalLoginItems,
                                                                         kLSSharedFileListItemLast,
                                                                         NULL, NULL,
                                                                         (CFURLRef)[[NSBundle mainBundle] bundleURL], 
                                                                         NULL, NULL);
    if (ourLoginItem) {
        CFRelease(ourLoginItem);
    } else {
        NSLog(@"Could not insert ourselves as a global login item");
    }

    CFRelease(globalLoginItems);
} else {
    NSLog(@"Could not get the global login items");
}

当我构建并运行应用程序时，LSSharedFileListInsertItemURL（）刚刚返回NULL。我还需要做些什么吗？某种授权？

注意：此处的用例适用于全局登录项，即使用kLSSharedFileListGlobalLoginItems而不是kLSSharedFileListSessionLoginItems。

Answer 1

我得到了这个工作。在将应用程序插入登录项之前，我所要做的就是添加这些行：

AuthorizationRef auth = NULL; 
AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &auth);
LSSharedFileListSetAuthorization(globalLoginItems, auth);

LSSharedFileListSetAuthorization的文档说我们必须为此获得正确的system.global-login-items，但它仍然有效！

但如果用户不是管理员，则会失败。为了使它能够工作，你必须这样做：

AuthorizationItem right[1] = {{"system.global-login-items.", 0, NULL, 0}};
AuthorizationRights setOfRights = {1, right};
AuthorizationRef auth = NULL; 
AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &auth);


AuthorizationCopyRights(auth, &setOfRights, kAuthorizationEmptyEnvironment,
                              (kAuthorizationFlagDefaults
                               | kAuthorizationFlagInteractionAllowed
                               | kAuthorizationFlagExtendRights), NULL);

建议您参考the docs了解详情。

这对我有用：

NSString * appPath = [[NSBundle mainBundle] bundlePath];

// This will retrieve the path for the application
CFURLRef url = (CFURLRef)[NSURL fileURLWithPath:appPath]; 

// Create a reference to the shared file list.
// We are adding it to the current user only.
// If we want to add it all users, use
// kLSSharedFileListGlobalLoginItems instead of
//kLSSharedFileListSessionLoginItems
LSSharedFileListRef loginItems = LSSharedFileListCreate(NULL, kLSSharedFileListSessionLoginItems, NULL);
if (loginItems) {
    //Insert an item to the list.
    LSSharedFileListItemRef item = LSSharedFileListInsertItemURL(loginItems,kLSSharedFileListItemLast, NULL, NULL,url, NULL, NULL);
    if (item){
        CFRelease(item);
    }
}   

CFRelease(loginItems);

Answer 3

NSString * appPath = [[NSBundle mainBundle] bundlePath];

        // This will retrieve the path for the application
        CFURLRef url = (CFURLRef)[NSURL fileURLWithPath:appPath]; 

        LSSharedFileListRef loginItems = LSSharedFileListCreate(NULL, kLSSharedFileListGlobalLoginItems, NULL);
        if (loginItems) {
            //Insert an item to the list.
            LSSharedFileListItemRef item = LSSharedFileListInsertItemURL(loginItems,kLSSharedFileListItemLast, NULL, NULL,url, NULL, NULL);
            if (item){
                CFRelease(item);
            }
        }   

        CFRelease(loginItems);

这段代码不起作用？我用kLSSharedFileListGlobalLoginItems替换了kLSSharedFileListSessionLoginItems

Cocoa应用程序如何将自身添加为全局登录项？
