使用CABasicAnimations和CoreMotion移动UIView

Question

I want to move my UIView up and down (x axis) with the accelerometer but keep it within the screen. Currently, I can't get it to move in coordination with the accelerometer. I have an NSTimer that fires every 0.05 seconds (which is how often the Accelerometer updates) and calls a method which attempts to move the UIView. How can I get the UIView to move based on the accelerometer's movement?

Answer 1

.05 seconds is too short an interval to do any meaningful animation. Think in terms of .1 seconds or so at a minimum.

If you can't get animations to work, post your code. Also tell us if you are using Storyboards (the default) or XIB files.

You really need to have a look at :
