iOS Question smoother movements

tufanv · Mar 30, 2016

Hello

I have a basic menu button. When i click it , sidepanel comes from the left with the help of a timer with interval 1. With each tick the panel moves to right with value 1. The sliding panel is not moving too much smoothly, it makes some lags. Is there any possible way to make it smoother ?

TY

Try to use the class attached. it ticks on each screen refresh so it will be smooth.

You can use it as a timer.

B4X:

dim tmr as CADisplayLink

tmr.initialize("tmr",me)
tmr.Enabled=true

Sub tmr_refresh

' each screen refresh

end Sub

You can customize it to tick on your desired interval with tmr.TimeStamp calculations

A general question: Do you have tried it in release mode?

now i tried it. Yes it is very smooth. What i couldnt manage is to calculate timestamp . When i start the animation, my left menu starts to slide to right but slowly(slower than a timer with interval 1 ). Can i make it faster like a timer with interval 1 ?

But for your issue you could also use LayoutAnimation and it will be better I think
