快速而肮脏只是为了显示它正在使用中
class AppDelegate
def application(application, didFinishLaunchingWithOptions:launchOptions)
@window = UIWindow.alloc.initWithFrame UIScreen.mainScreen.bounds
@window.makeKeyAndVisible
my_view = UIView.alloc.initWithFrame [[0, 0], [50, 50]]
my_view.backgroundColor = UIColor.greenColor
@window.addSubview my_view
UIView.animateWithDuration(0.25, animations: lambda {
new_frame = my_view.frame
new_frame.origin = [100, 100]
my_view.frame = new_frame
})
true
end
end

以下代码可用于动画对象。
my_view = UIView.alloc.initWithFrame [[0, 0], [50, 50]]
my_view.backgroundColor = UIColor.greenColor
view.addSubview my_view
my_view.frame = [[0,0],[0,0]] #the position from which animation begins
UIView.beginAnimations(nil,context:nil)
UIView.setAnimationDuration(0.05)
UIView.setAnimationDelay(0.2)
UIView.setAnimationCurve(UIViewAnimationCurveEaseOut)
my_view.frame = [[250,400],[50,50]] # the position at which the animation ends
my_view.backgroundColor = UIColor.blueColor #you can also change other properties while animating
UIView.commitAnimations

使用sugarcube!
frame = my_view.frame
frame.origin = point_a
my_view.frame = frame
# animating the move to point_b is EASY
my_view.move_to point_b

move: "my_id",
from: [10, 10],
to: [50, 50]
