cocoa - NSSharingService - 删除 facebook 和 twitter 并添加打印

Question

我刚刚实现了一个共享按钮，它有一个共享菜单:

 [_shareButton sendActionOn:NSLeftMouseDownMask];

并连接此操作:

-(IBAction)share:(id)sender {   
    NSArray *shareArray = @[@"testShare"];
    NSSharingServicePicker *sharingServicePicker = [[NSSharingServicePicker alloc] initWithItems:shareArray];
    sharingServicePicker.delegate = self;

    [sharingServicePicker showRelativeToRect:[sender bounds]
                                      ofView:sender
                               preferredEdge:NSMinYEdge];
}

现在回答我的问题，我不希望 Facebook 和 Twitter 成为菜单中的选项。我只希望电子邮件和消息可用。我还想添加“打印”，但不知道是否可以做到。

这可能吗？

谢谢

(没有足够的代表点来添加“NSSharingService”作为标签)

通过使用proposeSharingServices解决了这个问题。

- (NSArray *)sharingServicePicker:(NSSharingServicePicker *)sharingServicePicker sharingServicesForItems:(NSArray *)items proposedSharingServices:(NSArray *)proposedServices{

// Find and the services you want
NSMutableArray *newProposedServices = [[NSMutableArray alloc] initWithCapacity:5];
for (NSSharingService *sharingService in proposedServices) {
    if ([[sharingService title] isEqualToString:@"Email"] || [[sharingService title] isEqualToString:@"Message"]) {
        [newProposedServices addObject:sharingService];
    }
}
NSArray *services = newProposedServices;

NSSharingService *customService = [[NSSharingService alloc] initWithTitle:@"Print" image:[NSImage imageNamed:@"PrintImage"] alternateImage:nil handler:^{
    // Do whatever
}];

services = [services arrayByAddingObject:customService];

return services;

}
