How do I get the current x and y position so that I can use GCRectMake?
提问by Cesare
I have this code inside an animation:
我在动画中有这个代码:
image.frame = CGRectMake(x: x, y: y, width, height)
I need to get the x and y coordinates of an image. I found this Objective-C code:
我需要获取图像的 x 和 y 坐标。我找到了这个 Objective-C 代码:
CGPoint origin = imageView.frame.origin;
Once I find the x and y position of the image, I will need to transform it. I will use something like:
找到图像的 x 和 y 位置后,我将需要对其进行转换。我会使用类似的东西:
image.frame = CGRectMake(x-50, y-50, width+500, height+500)
...so that I can move the image around the screen. How do I find the original x and y positions?
...以便我可以在屏幕上移动图像。如何找到原始的 x 和 y 位置?

Do you mean you want this?
你的意思是你想要这个?
var frm: CGRect = imageView.frame
frm.origin.x = frm.origin.x - 50
frm.origin.y = frm.origin.y - 50
frm.size.width = frm.size.width + 500
frm.size.height = frm.size.height + 500
imageView.frame = frm
