[英]OS X Status Bar Application with a title in two lines
I'm an old iOS developer and now I want to make a simple OS X status bar application. 我是老iOS开发人员,现在我想制作一个简单的OS X状态栏应用程序。 I need to put a title at the NSStatusItem but it should be in two lines, like iStatPro network feature. 我需要在NSStatusItem上放置一个标题 ,但标题应该在两行中,例如iStatPro网络功能。
How should I add it? 我应该如何添加?
Here is a very simple example. 这是一个非常简单的示例。 This example shows two lines with two simple blinking lights. 此示例显示两行带有两个简单的闪烁灯。
It uses a NSView (Custom view) with two NSTextFields and two NSImageWells inside of it. 它使用一个NSView(自定义视图),其中包含两个NSTextField和两个NSImageWell。
The red and green light images are added to the project and set to the Image wells in IB. 红光和绿光图像已添加到项目中,并设置为IB中的图像孔。

I use two textfields as I think this will give better control if needed. 我使用两个文本字段,因为我认为这将在需要时提供更好的控制。 But you can use one and newline the text. 但是您可以使用文本和换行符。 @"Line 1\\nLine 2" @“第1行\\ n第2行”
I also had to set a Maximum line hight to help with the text alignment and had to fiddle with the constraints in IB. 我还必须设置“最大行数”以帮助文本对齐,并且不得不摆弄IB中的约束。
But the result is two lines with blinking lights: 但是结果是两行灯闪烁:
子类化NSView,您可以在其中手动绘制文本(搜索绘制的NSString),然后将视图添加到状态项。
