顶部的三角形看起来很漂亮,但我无法构建这样的三角形。
我尝试编写如下代码,但我看到了一个普通的菜单。
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {// Insert code here to initialize your application
NSStatusItem * statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:110] retain];
[statusItem setTitle:@"Test"];
[statusItem setEnabled:YES];
[statusItem setHighlightMode:YES];
statusItem.menu = [[NSMenu alloc] initWithTitle:@"menu"];
NSMenuItem * menuItem = [[NSMenuItem alloc] initWithTitle:@"menuItem1" action:NULL keyEquivalent:@""];
[statusItem.menu addItem:menuItem]; }
请帮我做点什么来实现它。非常感谢!
最佳答案
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification{
// Insert code here to initialize your application
NSStatusItem * statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:110] retain];
[statusItem setTitle:@"Test"];
[statusItem setEnabled:YES];
[statusItem setHighlightMode:YES];
[statusItem setTarget:self];
[statusItem setAction:@selector(showPopover:)];
}
- (void) showPopover:(id)sender {
NSLog(@"sender is: %@", sender);
RSTestPopoverViewController * viewController = [[RSTestPopoverViewController alloc] initWithNibName:@"RSTestPopoverViewController" bundle:nil];
NSPopover * popover = [NSPopover new];
popover.contentViewController = viewController;
[popover showRelativeToRect:NSZeroRect ofView:(NSView *)sender preferredEdge:NSMinYEdge];
}
popover回调的参数是NSStatusBarButton类的实例。 这是我的控制台中的输出。
