如何以编程方式使NSSlider垂直？

Question

我编写了一个Mac应用程序，并以编程方式创建了一些NSSlider。默认的NSSlider方向是水平的。如何使NSSlider成为垂直的？

Answer 1

目标C

我是用这个做的：

self.yourSlider.frameRotation = 90.0;
CGRect frame = self.yourSlider.frame;
float tmp = frame.size.height;
frame.size.height = frame.size.width;
frame.size.width = tmp;
[self.yourSlider setFrame:frame];
[self.yourSlider setWantsLayer:TRUE];

Swift

我猜斯威夫特的版本是：

self.yourSlider.frameRotation = 90.0
var frame: CGRect = self.yourSlider.frame
var tmp: Float = frame.size.height
frame.size.height = frame.size.width
frame.size.width = tmp
self.yourSlider.frame = frame
self.yourSlider.setWantsLayer(TRUE)
