Question

Mountain Lion提供了一个内置的共享按钮,可显示适合该应用的共享服务菜单:

如何将其插入我的应用程序？

Answer 1

要在Mountain Lion上添加分享按钮:

1)NSButton例如,添加一个被调用的shareButton.

2)为此按钮添加标准图像:

[shareButton setImage:[NSImage imageNamed:NSImageNameShareTemplate]];
[shareButton sendActionOn:NSLeftMouseDownMask];

3)进入"点击动作",呈现NSSharingServicePicker:

NSSharingServicePicker *sharingServicePicker = [[NSSharingServicePicker alloc] initWithItems:urls];
sharingServicePicker.delegate = self;

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

4)最后,实现NSSharingServicePickerDelegate方法来定制选择器的可用服务.
