Macos 在NSTabView上加载同一NSViewController的不同实例

我有一个NSTabView，其中我在其选项卡上分配并加载相同的NSViewController：

IRCView *viewirc = [[IRCView alloc] initWithNibName:@"IRCView" bundle:nil];
for (id view in [tabsView tabViewItems]) {
     [view setView:[viewirc view]];
}

如何在每个

NSTabView

选项卡上加载

IRCView

视图控制器的不同“实例”？因此，每个选项卡都可以与IRC服务器建立不同的连接（在本例中）

for(NSTabViewItem * tabViewItem in [tabsView tabViewItems])
{
    // instantiate a brand new IRCView for each tab view item...
    IRCView *viewirc = [[IRCView alloc] initWithNibName:@"IRCView" bundle:nil];

    // ... and do whatever customization you want to do for each IRCView here

    [tabViewItem setView: viewirc];
    [viewirc release]; // tabViewItem already retains
}
